I like good value just as much as the next guy and all, so after so long watching this channel I have way more faith in predator engines than I used to. Heard a couple stories of shredded piston heads when they were new and decided I wouldn't even look at them.
I caught the whole Velocity Dispatch episode on Friday and congrats on the win! Glad Isaac didn't crash when it broke loose on him during the first run.
If you guys want. I have a mini sprint kit, which would be really easy to mount with the motor mounts it had. Full set up for methanol. Fuel system and everything. It’s a 2014 suzuki gsxr 600
Trevor Colletti ...caint believe that I waited all that time to watch and something came up and I missed it...where can it be found? Please! PLEASE! ďà wòöķįęè
too bad about the spark issue. I'm glad you found the trouble and it wasn't more serious. When the new coils arrive and you install them, please take note of the inner circle of bolts in the flywheel. They are elongated to allow for timing advance adjustment. Consult with Performance 670 to see what they say the spark advance should be. There is a chance that the timing is set wrong.
You guys are doing fine. Perfect !! This gives everyone a starting point. Teaches us the best and fastest way to build ! Less work on our part . Thanks.
MrHillfolk couldn't agree more. If it wasn't for oe manufacturers champion wouldn't sell any plugs. When i bought my new harley as soon as i got it home i pulled those out and put in ngk
Thank u for the respect ive been a body man for 5 years now and i work mon-fri 630am to 6pm and some sat's but flat rate @17.50$ and turn 90 to 115 hrs a week pays off and supports my family
I just loved your show on TV. I cussed myself because I missed it the first go round but I caught it the second go round. Man you all were great. I was praying that cart was going to hit 100mph and sure enough it did. You boys don`t play around. You all Got-R-Did. lol
Kyle Baker Yes it is. About a year ago,I needed a 23hp Kawasaki engine replacement for a zero turn. I contemplated using a 670,and I priced em at just under 700$. I ended up finding a new 24hp Briggs for 740$ shipped. For an extra 50$ I've got a Briggs that I can get parts for and fix.
Kyle Baker Exactly. Actually for my employment, one segment is I work for a Briggs generator dealer. I got a better price off eBay than my job so I like saving $ too. Haha so I’m not too biased but sometimes a few bucks more gets a better product. I always liked the Kohler engines better than Briggs actually, but I guess some of the newer ones (courage) are really bad.
Thanks for another great video guys. I like the dragster most of all out of all your fantastic builds. I've been a mechanic here in Australia for nigh on forty years and have always done well with trouble shooting, usually I see Ike's logic process unfolding and its all but identical to my own. Great work, the both of you, not only mechanically, your video editing and camera work are excellent too. BTW, locally here in Oz we also share the "It'll be fine" attitude, but we term it, "She'll be right mate" lol.
Congratulations on beating the challenge for the Velocity channel!..I enjoyed watching it,it took some guts to do that,that big Ducati engine on that little frame was hairy!..If the 670 doesn't pan out,you aught to put the Ducati engine on the dragster..Its a heavier & stronger frame.
With all the work you did with the engine to increase the power and the RPM the clutch springs are very needed necessity as well as having an offset keyway to advance your timing, timing is very critical for making power on such a small engine. The new key ways usually are sold in two degree increments. And a big loud wind to you fellas today 😎 PS the magnet should be epoxied in place check clearances
I love your dragster.....and the twin cylinders concept is great.....I have 14 Exmark mowers I work daily and I tried using Predator engines as replacements for the Kohler engines after about 3300 to 3500 hrs. Terrible idea disastrous results 1000 to 1400 hrs tops......crank pistons and rods fine.....everything else...problem!
tip for bondo.....before you sand again, spray black paint from a far distance....just enough to cover little black dots all over......then sand with a block until all dots are gone. The dots will show you the low spots your eye cant see
Just a heads up a 2003-2005 yamaha R6 engine was fuel injected and made 110whp and the whole bike weighed in at 350lbs. If you were going the motorcycle engine route and didnt want to get something like a liter bike or busa engine that would be a solid contender.
It's always a good idea to either film or make a drawing of how things go together, both when undoing and doing things up. Hope you get it going real hard.
i think the magnets point the same way...its important to pass a magnetic field over a coil and the two magnets work together...if one is loose in there and bouncing around or getting pushed away from the coil that would have an ill effect on the spark
I don't understand the science behind it, but performance 670 told us specifically that while the flywheel is rotating clockwise the first magnet to pass a coil (if that makes sense) needs the north side facing the coil, and the second needs the south side facing the coil
As i (vaguely) understand it, north comes up to the leading edge of the coil, causing the magnetic field in the coil to shift one way, then as things go on around north hits the other side,with south hitting the leading, which rips the field the other way causing it to generate enough power to make the spark. Of course, I could be completely off, but it sounds good in my head at least.
That's pretty close. It has to provide like an AC wave, one magnet (nth) for positive pulse and the other (sth) gives a negative pulse. The module senses the negative swing and releases the primary (like a set of points opening) and you get a spark voltage from the coil. Because of the way it works the voltage peak and slope of the pulse also determines the timing advance so any change to coil resistance, air gap or magnets will effect not just spark voltage but timing advance too. So its critical to set the right specified air gap particularly if it has 2 separate coils that the air gap be the same for both. You can experiment with different air gaps to the rotor and use a timing light you may see the difference in ignition timing curve which gives you some means to fine tune the ignition timing on it for best power, as would different impedance coils. I've got a vid on how it works using a scope to show the voltage pulses and spark trigger point.
Had a one man watch party at my house. Very cool goKart . I can see how that lose magnet would cause a weak spark. The closer the magnet is to the coil, the more voltage is induced into the coil...makes sense to me.
The rollers will add stall, but its still going to clime the front pulley to quick, I think..basically like shifting to a higher gear to soon.. What I used to do back it the day on snowmobile clutches, was to add more tension to the spring on the rear pulley.. it was always amazing how much it improved acceleration. Its basically like waiting a little longer to shift to a higher gear. on the rear pulley, the slider sits in the valley.. carefully dissemble the rear pulley, while holding both inner and outer pulley, and keeping the tension on the spring. rotate the outer section of the pulley counter clock wise, so the the slide moves to the next valley to the left, putting more tension on the spring.. i would think that the manufacturer would have a stronger spring for that purpose also, but maybe not.. but adding more tension like I described does work also.
wow you guys are becoming superstars and i cant think of two better men for the job congrats on your success on the velocity channel like i said its a class act watch out that rooster will be jealous Ike lol
Nice vid. I can see your annoyance with these issues. I hate it when stuff just slowly falls apart everywhere, and then there’s so much that could be wrong, it is annoying to fix. Just adding to the list Header is rusting where the two pipes meet.
You guys rock. Just put your stickers all over my 13 year old sons first drift bike build with a 11hp honda and a moped front end. Air horn and led's to come. Keep up the hard work and i agree elec kart build.
Ditch those plugs and have gopowersports send you autolite AR3910X plugs. Also, again, loosen your coils, place a business card between the coils and flywheels and torque the coil bolts, it’s a good reference point. You are correct, the flywheel does tend to move as rpms climb, enough to touch and kill a coil if they touch, crankshaft flex.
To each their own, but I personally love the sound of a 4 cylinder bike engine, but you can't put a shit exhaust on there. If I had to make a serious recommendation for them, I would start looking for the engine out of a mid to late 90's Honda VFR750/Magna. A 750cc V4 that makes 80 HP at around 9,000 RPM sounds like nothing else out there. Check out Do It With Dan's videos on his Magna. IDK if I can paste links in here, but copy and paste this: /watch?v=VrV2CAJTRA0 after youtube . com into your search bar to hear the bike.
Guys I watched your video on the velocity channel it was very good I indeed enjoyed it thank you and keep up the good work. Get rid of that pos Predator 670 find a good engine to replace it with you will have alot more fun.
Hey guys I've been watching you both for the last 2 and half years and I'm addicted to you guys,and I can't even fine a go kart or mini bike to save my life,not even scrap ones...but nice work on the drag kart,my idea is to replace the entire ignition system with the spark plugs it's included....upgrade
Get yourself some dry guide coat powder off of Amazon, or find some high build primer in rattle can...that should help with the bodywork and getting it all smooth...
What's the compression ratio ? Make sure that's up there !!!! And what do your heads look like the shape does a lot for how the fuel mixes before it fires ! Try dimpling the piston with a drill bit in a small cluster and if you weld up the heads cut a pressure release channel like with a grinder this makes a improved quench effect ...all this will help the way the piston can help mix and maximize your fuel burn ! Also try brisk spark plugs ...I never made more power than with them ...there a triple spark ... call to get your conversion plug number might use a dr15zc but not sure depends on compression ....also make sure your plug boots are tight on the spark plug insulator if there not ,electricity will take the path of least resistance.. get som msd boots and then either run silicone tubing around the wire or dubble up some heat shrink tubing ...4 stroke have such weak spark compared to 2 stroke ....also is your case vented ? If not vent it a lot of pressure builds up in the case from the air against the side of the crank weights . Some people go as far as knife edging the crank for the less resistance reason alone ...these are cheap easy mods to try ...proven results
Aww yea,.. Paint job, maaan when you got a close-up 🤯 it pops!! Looks old-school, i like it. That dragster gotta hit 100mph before summer's end. With the 670, fellas can you do it??? I got faith in ya and a lil tweak here and there. I still say build a transmission from an old motor bottom-end, do away with chain setup and g with cvt axles similar to used in sand buggies with high torque&hp output. U guys are killin' it broh' s and the truck, it's coming along Jon. I noticed a few lil indentions when you were showing it. Could u used a shaping hammer from the inside and maybe tap those out?? Or were those rivets that'll only be able to bondo or fiberglass over?? I thought you welded it but i sometimes miss episodes so idk.. But..... It's taking shape. I remember a c10 i build with my step pappy wheni was 14yr old. Oh the joy and since of accomplishment everytime i looked at it or started it up, or drove it. Well until he got drunk and sold it to a dealership owner. He got himself a brand new z71 4x4 even trade, well a $44k truck at the time. I never got to drive it Even though i built the c10 fr frame up. It was nice. However i did learn basics in mechanic, body work. They can't ever take that away. Anyways watching y'all build is very inspirational. Thx for making us viewers feel like a part of something phenomenal ..😎👍👍
For me would be interesting to put a commercial Kawasaki or Kohler TWIN engine in of the same displacement and see what they would run...I have a landscape business and it was all about the Japanese engines for trimmers and 21"mowers as I was buying equipment starting in the 1990's. Briggs was a huge part of my teen teen years with mini bikes and home owner lawn mowers and having to spend $10 grand on a commercial mower that only came with a Briggs was really a tough sell, so far they are what you would expect fairly tough and burn a lot of oil. I know that these motors are actually meant to be Governed and run at a max RPM and you guys trying to get them to run full skirt up is not really what they like so it might be a good idea to drop some Royal purple in and find a giant oil cooler and fan to keep them happy?
Guys great vids btw . Went back on some of ya old vids and seen the drift trikes with a turbo .. need to bring em back and re do what u wanted to fix . Have a retro day or something ? Would be awesome .
Guys, I missed the Velocity show, but wanted you and the fan base to know the show, Velocity Dispatch, is available to stream a la carte on Vudu for $1.99 for the episode - I’ll be checking it out today, peace and pistons!! C
It’s actually really cool seeing you guys polish that turd of a v-twin. I want to see you guys push the engine to its max. Like an underdog story. Ps- I don’t think you’ll break anything. I think the tires will spin before you start popping wheelies, or the engine will die a glorious death. Need some slicks.
The weak spark could be the result of one cylinder being dumped to pass EPA testing or to comply with some dumb gas millage regulation on small engines so you need to by-pass the rig. Could be a solid copper core plug wire is needed (thicker is better) or a by pass system on the mag. For racing you could also try shaving the heads down 0.30 or more to get some more compression and also polish the intake system to very smooth and shinny to help with gas and air flow. Get a turbo that will do the trick.
you guys should do a 3 wheeled dragster and use a harley rim with a car tire on it for the drive. that bad boy has a lot of rotational weight and friction with the 2 wheel set up.
Back in the 90s in a place called goose rock kentucky its in manchester ky, there was 2 guys that had 2 dragsters like yours with gsxr 1000 motors it was the bud rail and bud light rail it was a dirt drag
Bondo was created for body shops so they could get jobs done fast and out the door. All custom experts use lead. Takes longer but last a life time. Will not crack or absorb moisture and cause rusting. If your going to keep this truck for awhile that makes sense. If your going to turn it over in no time your doing great. But then again that is just my opinion. And leading has a learning curve.
"We got AC spark plugs. They didn't have Champions." Well, a history lesson here. The "AC" in AC Delco, stands for Albert Champion. Al didn't start 1 plug company, he founded 2. en.wikipedia.org/wiki/Albert_Champion_(cyclist) steve
John, 220 is too fine for shaping body filler. Use 36, then 80 grit to get your basic shape. Leave the last coat of filler just high enough to remove all the 80 grit marks with 180. I rarely go any finer than 180 before priming. Also, id stay away from the rattle can stuff. Invest in some type of gun and a 2k high build primer from your paint store, feather fill or an equivalent product may be an even better option at your current stage in the process. Etching or epoxy primers are needed for bare metal prior to high build products to ensure long term adhesion. A PPG rep once pointed out to me that quality etching primers use an acid component that comes in a separate plastic jug and must be added before use. If it comes as one product in a metal can it cant have much if any ability to etch metal, otherwise it would soon destroy its container. That being said, I, and from what I can gather most other professionals tend to lean toward epoxies more than etch primers. Also, when you need to build a line or such as the one up the center of your post you might find it helpful to use masking tape up one side of the line as you sand the opposite side. Particularly as you work into finer grits the tape will raise the sand paper off the surface just enough to help that line form nice and strait. I hope this helps a little.
The best way to fix something, is to understand how it works in the first place. Also, there are air gap specifications (feeler gauge measured) to avoid uneven ignition pickups for any engine. Guessing means wasted time and money.
We are going to find out what the weak link is in the drivetrain is when you get your coils. I suggest changing out that toggle ignition switch with a real ignition switch. Those toggles are built sorry and could be not fully turning on causing low spark also. I have seen plenty of faulty switches causing no spark/weak spark problems.
A few episodes ago you guys were talking about an EFI setup... I am pretty sure MegaSquirt has the ability to do a V-Twin configuration, and would allow you to get rid of those magnets / weak spark.
Those new coils should make her run good. I would like to see you guys run a BIG Carb as well. Maybe the next step for crazy fast times is get a Vtwin from a Harley or a Japanese cruiser. I think you guys would have more fun with gears.
All those engines that use that style of coil and a magnet on the flywheel use the same gap. I always used a match book. Lessen upthe bolts, put the matchbook down, set the coil down then tighten it up.
I’ve been doing auto body since 1986 The sanding block is your friend get a med and small 3m and a long board after you Cheese grade you’ll block it with 36 or 40 grit leaving enough filler to come through with your 80 after that if it feels straight prime then while it’s drying give the primed spot a light guide coat fuzz of flat black after that dries block again with 220 then repeat prime fuzz then 400 then prime with a good epoxy primer and guide coat it again , block it again then seal it and you can paint it black if you wanted to Let the critics begin

Isaac's booger analogy was epic. You boys are nuckin' futts. Great job!!
Weak spark helps explain our slower times at the drag strip. Plus with these new rollers this thing will launch even harder!
CarsandCameras getting her in the Power Band during launch will help a lot and will also test that drivetrain
CarsandCameras yes I love that idea where is your meet and greet going to be
I like good value just as much as the next guy and all, so after so long watching this channel I have way more faith in predator engines than I used to.
Heard a couple stories of shredded piston heads when they were new and decided I wouldn't even look at them.
CarsandCameras put it on methanol an add some timing an it will wake it up a lot
Maybe find some neodymium magnets?? Should give you better spark than the original sintered iron magnets.
5:20 Ike's attitude made my day! LOL
I can't wait to see it launch now!
You guys are Kings of the small motor TH-cam world. Wish you both the best. Been watching this channel since the beginning. Wish I lived closer haha
I caught the whole Velocity Dispatch episode on Friday and congrats on the win! Glad Isaac didn't crash when it broke loose on him during the first run.
If you guys want. I have a mini sprint kit, which would be really easy to mount with the motor mounts it had. Full set up for methanol. Fuel system and everything. It’s a 2014 suzuki gsxr 600
Caswell Racing 76: I have a suzuki GSX600R KATANA bike too. It's a 1993, SUPER fast. I love that bike. 😁
Congrats on the tv airing, the show was awesome! Glad to see you guys are making your way up in the world and that Ike is still alive and well.

Champions are junk as plugs. The best option for small engines i think is ngk
Bob Keller
Champions are only good if you have spares😀
Ngk ftw
MrHillfolk couldn't agree more. If it wasn't for oe manufacturers champion wouldn't sell any plugs. When i bought my new harley as soon as i got it home i pulled those out and put in ngk
E3 are what i run in my 200 2 stroke and i have never fowled it. NGK are good plugs but i love E3's
Bob Keller
I wouldn't use champion plugs for paper weights! I always run ac or NGK.
James stranger lol. Not many people would. I literally have never met anyone who likes champion plugs. I work at napa and never sell any!
i like the fact that your modding it. trying to improve the smaller platform.not just slapping something know to already be fast in there.
My dad was into drag racing snowmobiles for a long time, and I'll tell you that getting CVT clutching right is an art and a pain in the ass
You guys rock and at first when he was rocking that crank back and forth it sounded like connecting rods were loose
Thank u for the respect ive been a body man for 5 years now and i work mon-fri 630am to 6pm and some sat's but flat rate @17.50$ and turn 90 to 115 hrs a week pays off and supports my family

Still waiting for that wrench that ike threw to fall.
Should be about the same time as that giant booger!
Legend says that the wrench is still falling.
Just don't let it wind up like Red Beards 670. 🔥
Allen McKinney the 670 is crap
Allen McKinney that was rough.
Kyle Baker
Yes it is.
About a year ago,I needed a 23hp Kawasaki engine replacement for a zero turn.
I contemplated using a 670,and I priced em at just under 700$.
I ended up finding a new 24hp Briggs for 740$ shipped.
For an extra 50$ I've got a Briggs that I can get parts for and fix.
MrHillfolk and it’s a name you can stand behind
Kyle Baker
Exactly.

The velocity episode was awesome! I watch you guys religiously. Would be cool for you guys to get an actual show.
Thanks!

CarsandCameras: What are you guys setting your coils to from the flywheel? I set mine to .010 and gets great spark.
hwesson: Interesting? Never really thought much about that, but would be interesting to learn about.
Shes going to fly cant wait to see next update... awesome ...

Terry Baker thanks
That thing sounds better than a Harley. Damn can’t wait until the next run at the track!
wow you guys are becoming superstars and i cant think of two better men for the job congrats on your success on the velocity channel like i said its a class act watch out that rooster will be jealous Ike lol
And the booger incident makes you reconsider Mechan-IKE'S cooking episode. LOL HAHAHAHA!!
fan1701 🤣🤣🤣
Nice vid. I can see your annoyance with these issues. I hate it when stuff just slowly falls apart everywhere, and then there’s so much that could be wrong, it is annoying to fix.
Just adding to the list
Header is rusting where the two pipes meet.
Ive been waiting for this.. somehow i missed it..i dont know how though the bell was hit.. Anyway your on here thats what matters. Thanks guys
Jay Walker My “bell” doesn’t work either! 🧐
Haha loved the wrench toss Issac! 😂
You guys rock. Just put your stickers all over my 13 year old sons first drift bike build with a 11hp honda and a moped front end. Air horn and led's to come. Keep up the hard work and i agree elec kart build.
Thanks man!
Good job guy's 'tune what ya got to the max'
Ditch those plugs and have gopowersports send you autolite AR3910X plugs. Also, again, loosen your coils, place a business card between the coils and flywheels and torque the coil bolts, it’s a good reference point. You are correct, the flywheel does tend to move as rpms climb, enough to touch and kill a coil if they touch, crankshaft flex.
Awesome show guys! I hope you get to do another episode.
One thing the 670 will do that any sport bike engine won't do is sound that good
bud have you herd the Ducati paingale 1299
personally I would go a built banshee 2 stroke twin. sound shits on any sport bike, Harley or built 670.
Mow Money Mods yea man I also love them two smokes
A good old Harley engine would sound great
To each their own, but I personally love the sound of a 4 cylinder bike engine, but you can't put a shit exhaust on there. If I had to make a serious recommendation for them, I would start looking for the engine out of a mid to late 90's Honda VFR750/Magna.

Get yourself some dry guide coat powder off of Amazon, or find some high build primer in rattle can...that should help with the bodywork and getting it all smooth...
What's the compression ratio ? Make sure that's up there !!!! And what do your heads look like the shape does a lot for how the fuel mixes before it fires ! Try dimpling the piston with a drill bit in a small cluster and if you weld up the heads cut a pressure release channel like with a grinder this makes a improved quench effect ...all this will help the way the piston can help mix and maximize your fuel burn ! Also try brisk spark plugs ...I never made more power than with them ...there a triple spark ... call to get your conversion plug number might use a dr15zc but not sure depends on compression ....also make sure your plug boots are tight on the spark plug insulator if there not ,electricity will take the path of least resistance.. get som msd boots and then either run silicone tubing around the wire or dubble up some heat shrink tubing ...4 stroke have such weak spark compared to 2 stroke ....also is your case vented ? If not vent it a lot of pressure builds up in the case from the air against the side of the crank weights . Some people go as far as knife edging the crank for the less resistance reason alone ...these are cheap easy mods to try ...proven results
Love your builds..especially the slingshot..hopping you guys build a custom mini chopper/trike some day
I can't wait to see that thing rip with the high stall now.
Good show guys!
I loved the booger analogy it was priceless and exactly accurate
that is a really fast car to me keep up the good works
Aww yea,.. Paint job, maaan when you got a close-up 🤯 it pops!!
Looks old-school, i like it. That dragster gotta hit 100mph before summer's end. With the 670, fellas can you do it??? I got faith in ya and a lil tweak here and there.
I still say build a transmission from an old motor bottom-end, do away with chain setup and g with cvt axles similar to used in sand buggies with high torque&hp output.
U guys are killin' it broh' s and the truck, it's coming along Jon. I noticed a few lil indentions when you were showing it. Could u used a shaping hammer from the inside and maybe tap those out?? Or were those rivets that'll only be able to bondo or fiberglass over?? I thought you welded it but i sometimes miss episodes so idk.. But..... It's taking shape. I remember a c10 i build with my step pappy wheni was 14yr old. Oh the joy and since of accomplishment everytime i looked at it or started it up, or drove it. Well until he got drunk and sold it to a dealership owner. He got himself a brand new z71 4x4 even trade, well a $44k truck at the time. I never got to drive it Even though i built the c10 fr frame up. It was nice. However i did learn basics in mechanic, body work. They can't ever take that away. Anyways watching y'all build is very inspirational. Thx for making us viewers feel like a part of something phenomenal ..😎👍👍
I love Ikes analogy because it's so true lol
For me would be interesting to put a commercial Kawasaki or Kohler TWIN engine in of the same displacement and see what they would run...I have a landscape business and it was all about the Japanese engines for trimmers and 21"mowers as I was buying equipment starting in the 1990's. Briggs was a huge part of my teen teen years with mini bikes and home owner lawn mowers and having to spend $10 grand on a commercial mower that only came with a Briggs was really a tough sell, so far they are what you would expect fairly tough and burn a lot of oil. I know that these motors are actually meant to be Governed and run at a max RPM and you guys trying to get them to run full skirt up is not really what they like so it might be a good idea to drop some Royal purple in and find a giant oil cooler and fan to keep them happy?
🤣🤣 it goes flinging.... an sticks to the wall!!!!!! Lost it lmao
Guys great vids btw . Went back on some of ya old vids and seen the drift trikes with a turbo .. need to bring em back and re do what u wanted to fix . Have a retro day or something ? Would be awesome .
Love this dragster
awesome as usual guys
Guys, I missed the Velocity show, but wanted you and the fan base to know the show, Velocity Dispatch, is available to stream a la carte on Vudu for $1.99 for the episode - I’ll be checking it out today, peace and pistons!! C
Its forever enshrined in the dictionary of technical jargon..."Ike's Booger Analogy". Let us never forget, or let him live it down.
For your body line up the cab, use masking tape on one side and sand then switch to the other side to get a clean crisp body line.
That snot a very accurate analogy! ;-) But it'll be fine.
It’s actually really cool seeing you guys polish that turd of a v-twin. I want to see you guys push the engine to its max. Like an underdog story.
Ps- I don’t think you’ll break anything. I think the tires will spin before you start popping wheelies, or the engine will die a glorious death. Need some slicks.
It'll be fine
Great video, thanks guys!
The weak spark could be the result of one cylinder being dumped to pass EPA testing or to comply with some dumb gas millage regulation on small engines so you need to by-pass the rig. Could be a solid copper core plug wire is needed (thicker is better) or a by pass system on the mag. For racing you could also try shaving the heads down 0.30 or more to get some more compression and also polish the intake system to very smooth and shinny to help with gas and air flow. Get a turbo that will do the trick.
you guys should do a 3 wheeled dragster and use a harley rim with a car tire on it for the drive. that bad boy has a lot of rotational weight and friction with the 2 wheel set up.
Ike is the calm quiet kind of angry hahah
Great "finger/booger" analogy!!
Back in the 90s in a place called goose rock kentucky its in manchester ky, there was 2 guys that had 2 dragsters like yours with gsxr 1000 motors it was the bud rail and bud light rail it was a dirt drag
Glad I clicked! Subbed
Looks like a fun thing.
Ike's analogy made sense.
Bondo was created for body shops so they could get jobs done fast and out the door. All custom experts use lead. Takes longer but last a life time. Will not crack or absorb moisture and cause rusting. If your going to keep this truck for awhile that makes sense. If your going to turn it over in no time your doing great. But then again that is just my opinion. And leading has a learning curve.
A 34 to 36 mm flatslide carb would really do you justice trust me.
I would have put a little hot glue on them magnets just to hold them more secure. Nice vid well done.
"We got AC spark plugs. They didn't have Champions."
Well, a history lesson here. The "AC" in AC Delco, stands
for Albert Champion. Al didn't start 1 plug company,
he founded 2.

John, 220 is too fine for shaping body filler. Use 36, then 80 grit to get your basic shape. Leave the last coat of filler just high enough to remove all the 80 grit marks with 180. I rarely go any finer than 180 before priming. Also, id stay away from the rattle can stuff. Invest in some type of gun and a 2k high build primer from your paint store, feather fill or an equivalent product may be an even better option at your current stage in the process. Etching or epoxy primers are needed for bare metal prior to high build products to ensure long term adhesion. A PPG rep once pointed out to me that quality etching primers use an acid component that comes in a separate plastic jug and must be added before use. If it comes as one product in a metal can it cant have much if any ability to etch metal, otherwise it would soon destroy its container. That being said, I, and from what I can gather most other professionals tend to lean toward epoxies more than etch primers. Also, when you need to build a line or such as the one up the center of your post you might find it helpful to use masking tape up one side of the line as you sand the opposite side. Particularly as you work into finer grits the tape will raise the sand paper off the surface just enough to help that line form nice and strait. I hope this helps a little.
The best way to fix something, is to understand how it works in the first place. Also, there are air gap specifications (feeler gauge measured) to avoid uneven ignition pickups for any engine. Guessing means wasted time and money.
love the bugger analogy 🤣🤣
We are going to find out what the weak link is in the drivetrain is when you get your coils. I suggest changing out that toggle ignition switch with a real ignition switch. Those toggles are built sorry and could be not fully turning on causing low spark also. I have seen plenty of faulty switches causing no spark/weak spark problems.
A few episodes ago you guys were talking about an EFI setup... I am pretty sure MegaSquirt has the ability to do a V-Twin configuration, and would allow you to get rid of those magnets / weak spark.
Loved the booger analogy
Those new coils should make her run good. I would like to see you guys run a BIG Carb as well.
Maybe the next step for crazy fast times is get a Vtwin from a Harley or a Japanese cruiser. I think you guys would have more fun with gears.
What is the name of the show and episode number that y'all were on the velocity channel? I want to try to find it online.
Velocity dispatch episode 1.
havent found it.
I found it on on demand on tv.
All those engines that use that style of coil and a magnet on the flywheel use the same gap. I always used a match book. Lessen upthe bolts, put the matchbook down, set the coil down then tighten it up.
yay, another dragster video!
I’ve been doing auto body since 1986
The sanding block is your friend get a med and small 3m and a long board after you Cheese grade you’ll block it with 36 or 40 grit leaving enough filler to come through with your 80 after that if it feels straight prime then while it’s drying give the primed spot a light guide coat fuzz of flat black after that dries block again with 220 then repeat prime fuzz then 400 then prime with a good epoxy primer and guide coat it again , block it again then seal it and you can paint it black if you wanted to
Let the critics begin
Say gday to Chris from rather b welding!! You guys will get on awesome I reckon!! Rob in Tasmania!!
I took auto body in high school for 3 years and i miss it sooooo much😫
Good stuff. Enjoy your trip to Texas
episode on velocity was awesome guys just the music repeating over and over got to me but overall two thumbs up from me
tyler larson thanks
hope to see you guys on tv again soon! keep up the awesome content as always
