I remember I was 9 yrs. old had a paper route. I lived in Pompano bch. Florida. I saved all my money wanting a mini-bike. Saved 200 dollars that was a lot of money back then. I went to Uniroyal bought a green 3 1/2 horse clinton minibike for that 200 bucks I had. It did 50 mph. God I was in heaven..

After getting addicted to minibikes after your videos I built a 60 mph predator for probably around $100 ; done the governor removal, 24mm nibbi, header pipe I got off Facebook for cheap, and 18 Lbs valve springs, on a ct200u frame 10t clutch 50t sprocket , will run 57-60 all day
@@Black66 oh I got rid of the ct200u frame last night lol, found a kid that traded me even for a 1980’s sensation frame , he had no idea what he had lol; definitely hats off to you for my new hobby! Thinking about getting a rascal lite kit, hard to beat that for $500
Perfect timing. I'm putting a Predator 212 on my old Coleman CT200U tomorrow. I'm have the stage 1 ready to go on it with a header and do the zip tie on the governor. I'll have some fun on it then probably do the upgrades in this video. Thanks man! ✌
Black66…. Can you possibly make a video showing how you align the chain correctly when putting it on the front and back sprockets? I’ve also wondered how to align or square things up when installing a torque converter.
Moving away from the stock flywheel with the governor removed seems like a good idea for operator safety anyway. Plenty fine in spec I'm sure, but probably not a few thousand rpm higher!
This is all great. While you are taking the piston out, change the connecting rod to a Billet Rod for higher RPM safety and they come with replaceable bearing . Keep same cam and don't bother porting or polishing the head. Drill holes in the stock muffler.
Check out the playlists on the channel for billet rod and flywheel installs along with a stroker kit for good measure. Here is the link to one of them . Thanks for watching th-cam.com/video/VbcpA0jdSIw/w-d-xo.html
I did the flywheel and 12 degree key it's jetted 38 with air cleaner and exhaust I'm not at high elevation the 30 thousands gap seems to much it runs fine but slight misfire at idle I've got the head gasket and springs not installed yet
At 14:40 flywheel 8° advance pre-installed/off the shelf. Completely understand where your going. Now, here me out. How about cam timing, when changing cam out? Dont cam manufacturers sometimes have a little advance made into them as well? Whether regrind or new billet?
See where I am going? I'm basically taking this videos timing principles education, and trying to add some info. I'm coming from automotive principles. So, moving the powerband/peak hp or tq observed at different rpm throughout the range. Ignition timing can manipulate peak hp at different rpm. Also, cam timing too. I don't have much experience using a degree wheel/reading cam cards/checking valve/piston clearance with putty/etc etc. That's probably why my car project's engine build, where I installed a schrick camshaft "straight up", choosing to skip degreeing the cam. I think it was a mistake, and I probably left some untapped hp on the table. My motor never had a strong idle performance, but upstairs (peak 7k rpm fuel cut) it made all its hp. I didn't like my results in the end. Kept dreaming of tearing it all down someday, and really get into the "meat n potatoes" of playing with cam timing, using an adjustable cam gear, and recording max advance/retard degrees, that way I'd know what is simply too much/dangerous/risk of valve to piston contact.
The flywheel that I used has around 18 degrees of timing. The sweet spot on these little engines is about 32 give or take depending on the setup. Most billet wheels come with about 32 degrees of timing. I could have gotten away with more timing on this one. This setup is for the average person throwing this together in the garage with minimal tools. Inexpensive simple and easy. Definitely could degree in the cam but this wasn't in the scope of this video. Thanks for watching!
I bought a high-performance Minibike about a week ago and I found a box that came with it in the back of my car in the box was a brand new 212 predator hemi never even taken out of the box, a brand new front tire a brand new rear tire, a brand new 18 tooth clutch a brand new clutch gas throttle and cable and a brand new seat all wrapped up in plastic still all I needed was a frame. This morning I found a Azuza frame in excellent condition for 20 bucks. So I pretty much got this minibike for free except for the front and rear rim now I’m going to do the mods that you just did. Thank you to you and my son‘s gonna have an awesome little Minibike it’s gonna cost me about 140 bucks with everything
Great video man I liked how u pressed the springs in. Gonna have to try making one of those out of a chain saw tool... So when buying a new motor should I break it in first b4 I rebuild it..... Gonna go billet rod n flywheel. Any advice for my first build bud... Love your channel..
This is what I have found as I have installed several preditor engines on similar mini bikes from the 2 or 3 manufacturers that HF uses. Meaning there is a standard and a hemi version. So far I have managed to get a top speed of 58 ~ 59 mph in their stock version, all by fiddling with the gear/sprocket sizes. What I also discovered is that after it maxes out on RPMs the valves simply start to float meaning the engine has hit it's limit. From that point no amount of modifications will increase the power unless you install lighter valves,and stronger valve springs. Once you do that you can you go on to purchase all the other go fast aftermarket parts. If done correctly the bike can hit 80 mph, and I'm almost there.
Which option is better for plugging the holes in this case: blue or black RTV? Is it necessary to wait the full 24 hours for it to cure before running the engine and riding?
Hey i'm looking to get into mini bikes and not sure what parts to get i tried to use the links in the description but all of them were out of date if you could update them I would appreciate that so much!
I’m curious as to what kind of mileage the bikes get as they get modified too! Mpg stock then mods…..im thinking they might actually improve! It might be easier to check the mileage by quart than mileage per gallon…save you some time! You could rig up a small tank and just hang it on the frame with a hook and baling wire with a piece of clear fuel line…..what do you think? I’ve always wanted to know how far these minis could go on a tank anyway!
Held .21 gal so it got 75 mpg….I always wondered. As the mods are installed, I would think the mileage would go down, but how much. Reason I’m asking is in case of an EMP, these minis might be the only thing we could get around on! And I wonder if the electronics would survive the pulse, cause the electrics are so rudimentary and still very robust. Thanks for getting back to me. I’m thinking about building my own bike adult size kinda like the groundhog. I’m sure you’ve seen it on utube. Comfort would be much improved for adults on a bigger bike. I love watching your builds and thanks for your exportice on the subject, and appreciate you taking the time to share your knowledge.
Would recommend checking and clearing big end rod clearance too-its often tight. I wonder how it would react to at least 1 stamped 1:1.3 rockerarms - plenty cheap. Oops my bad
Hey black! Just fyi. I got an oko $20 flat slide carb from Amazon and put it on my ct200u. It’s stock with a header. This carb is great! Came with main and slow jets also. I think it might be better than my mikuni??
Excellent video. Good advice, clear demo, pacing and narration keep it interesting. Suggest you mention the torques you're using, as well as valve clearance. What were your sources for the various parts? Particularly interested in the cast aluminum flywheel. Thank you!
@Black66 Question: The flywheel you linked from studz racing, they claim it fits "Honda clone engines only" and not predator.. nut we see you using it here on a predator engine. Is there a difference in these two tapers, if so, what is it? And how did you manage to use the EC Flywheel? (looks like you cleaned yours up a bit too) I ordered one for my 212 predator and studz racing is giving me trouble about it!
Yes, the taper on the clone and standard 212 are slightly different. There are differences in opinion on using the clone wheel on a standard crank. I have used them without a problem. I am not saying he is wrong, Other folks might have had diffferent experiences with this stuff than I have. I make sure to lap the wheel in with a good valve grinding compound before torqing the wheel.
@Black66 thank you! Eric from studz racing is telling me to return the flywheel and "just by the billet flywheel" but I'm building a cheap 212 here for a mini bike... I don't need $120 billet flywheel on a stock un-reinforced 212 block. Any tips for lapping the clone flywheel to the predator properly?
I use valve grinding compound and run the wheel back and forth until I get an even sanded surface on the crank as seen in the video. Also there is a link in the video description for a vendor that sells this wheel with the same taper for the 212. His wheel has 28 degresss timing built in in case you don't want to use the offset keyway to advance the timing.
Nice video learned. For me that 5mph top end isn't worth making allot more noise imo. Unless the stock muffler doesn't really do much noise canceling any ways. I'd go the other way if I could get quieter muffler and lose some top end. Unless you live around country roads your not goin 50mph very much anyways. Likely get up to speed and slow down after a few seconds randomly.
seems to me if your going to build a cycle kart this stock 212 is the way to go considering how much the ghost motor and hop up kit is .its way more bang for your buck.
Great video ! You work fast! When putting the engines back together, could you mention what you torque the bolts and other small things like that so we can make sure engine is put together correctly. I'm a old newbie learning to work on small engines. Enjoying your content.
I would love to know how you get 50mph out of a stock predator! We have built around 10 bikes so far and i think the highest our speedo hit was 38mph. 50mph seems untouchable witjout upgrades. Maybe our gearing is just way off
Gearing is a big deal with these things. Too much gear and it will actually be slower even though on paper it says faster. Check out this video th-cam.com/video/xV8i59aGUao/w-d-xo.html
Well I bought everything on your list for my very first 212 build! Super stoked about this! I still won’t have anything to put it on, but I’m intrigued by the build itself. Sure will be one bad shelf engine untill I find something to put it on!
As long as you're having fun that's all that counts!! I would throw a sweet-looking blower housing on it. Like chrome or powder-coated blower housing so it will look even sweeter sitting on the shelf!!!👍
@@Black66 so the stock carb is trashed, I’m really not trying to spend a load on the Mikuni vm22, I’ve found a few other brands on Amazon, “knock off” would you say that would be ok for this cheap build? I’ve seen a few reviews and I’m not sure what to do exactly, some say the stock carb is better than the knock off? Would it be in my best interest to buy the stock one or knockoff. Unless you know of somthing better? Really appreciate the advise!
Given my weight, the fact that I want to ride on dirt and grass, and the minor hills of my terrain, I'd give up 20 mph worth of top end gearing for more torque and acceleration. Might keep the clutch alive too.
Great video, I noticed that you got the bike up to 50mph only with the governor ziptied on a stock 212. I have a cc100x with a stage 1 predator 212 hemi(jetted carb, intake, pipe, ziptied governer) but it only does around 35 as its top speed. Could this be because I am using a 12t clutch with a 75 rear sprocket? If I changed the sprocket to a 50t would it get a higher top speed? Thanks
Hey, just a tip, a large reason the stock rod blows up on the 212 is due to not enough oil entering the linkage with the crankshaft. Maybe drilling a hole on the conrod would allow oil to seep into it, giving it similar lubricating properties as the billet rod.
How did you hook up the throttle back together because I tried following your video for the governor removal and now I’m stuck on how to hook up the throttle
I bought it used. Not sure what store it came from. I use it for my minibike TH-cam channel. Thanks for watching. th-cam.com/channels/x9Ph4--sJxfQPzk_oEq8-g.html
Hey, I'm 14 and I want to get into building my own first minibike! I will go with the 212 predator engine but I am having trouble finding a good budget frame! and I was wondering if you could link the frame you are using in this video. Is the frame purchasable by itself? thank you.
I think it would be great if you make a new budget build minibike because all the parts shown don't exist anymore Keep up the great work I love your vids so far!
This was really cool video. Really like budget builds. Cool trick with the rod polish I’ve never seen or heard of that before. How much safer you think that makes a stock rod on the predator?
Thanks! Not sure on the rod. It was an old racers trick that has been used for ages. I would have to do a test or comparison on it to find out for sure .
I was wondering how much valve clearance is in a non hemi predator engine. I am building my first motor and I bought a cam from go power sports. It is the 265 hot cam, I am thinking of mating it with the 1.3 rockers you are using in this video however I don't want valve clearance to be a issue. Thank you for your time.
A standard predator is easier to use higher lift cams in because the valves are not angled or canted. If you use around .080” piston to valve clearance and .030” piston to head you should be fine.
Hello , another great video . I assume this flywheel would work on the predator 224 , same taper ? Was it a good fit , seemed it rocked back and forth a bit before you torqued it down ?
Yes, It will work on the 224. The reason it rocked back and forth was the 7 degree flywheel key . It lets the flywheel move so you can rotate it forward to get the 7 degrees of additional timing.
Black66. Iam Working On Taco 22 Mini Bike At The Moment Iam Going With The Briggs 5 horse. I Have Been Looking At Mods For A Frijole Mini bike. Iam Using The 196cc On That. Thank's For The Ideas.And Keep The Videos Coming
I just received my stage 3 header pipe from gopowersports for my 224 and it doesn't fit? Neither the gasket or the flange... did you have these problems when using some of your 212 exhausts?
If you watch the 224 playlist you will see, I changed out the head at some point in the build. You can use them . You have too oblong the holes with a Dremel or file.
So you want your timing key out of the way from the groove behind where you installed yours? Like if put the back end of my timing key flush with the groove behind it then would I'm good?

Amazing work that bike is fast
I have a few of those flywheels on various units. Very good value for money
They look like a clone of the GX200 aluminum. I wonder how they come timed. The GX200 aluminum is timed at 22 BTDC.
@@Deucealive75 I can't remember around 26 or 28 i think.....They responded well to an 8 degree advance key for me
1:29 where did you buy that lift thingy the bike is supported on?
Need to know too I just bought a predator engine for my bike yesterday but trying to figure out how to hold it up
Great video man I liked how u pressed the springs in. Gonna have to try making one of those out of a chain saw tool... So when buying a new motor should I break it in first b4 I rebuild it..... Gonna go billet rod n flywheel. Any advice for my first build bud... Love your channel..
Thanks! I would break it in after I installed the billet rod and flywheel.
This is what I have found as I have installed several preditor engines on similar mini bikes from the 2 or 3 manufacturers that HF uses. Meaning there is a standard and a hemi version. So far I have managed to get a top speed of 58 ~ 59 mph in their stock version, all by fiddling with the gear/sprocket sizes. What I also discovered is that after it maxes out on RPMs the valves simply start to float meaning the engine has hit it's limit. From that point no amount of modifications will increase the power unless you install lighter valves,and stronger valve springs. Once you do that you can you go on to purchase all the other go fast aftermarket parts. If done correctly the bike can hit 80 mph, and I'm almost there.
Check out the playlist for many Performance engine builds and part comparisons along with top-speed runs! th-cam.com/video/wHIKyVU4oxw/w-d-xo.html
BROOOOO Drill press valve spring tool. That's genius.
Thank U so much for your Video and Help and information.
Anyway you can list your tool list you used for the build? Thanks! Love the videos
I’m curious what was the purpose of “lapping the flywheel “ and if I go with the same flywheel do I also have to do this ?
great video, well put together ❤
Thanks!
@@Black66 hey how did you remove the gear off the crankshaft
@@magmasloth3619 I put the crank in a vise to hold it and used a small hammer and a punch. It will come right off pretty easily.
Great video sir !
Which option is better for plugging the holes in this case: blue or black RTV? Is it necessary to wait the full 24 hours for it to cure before running the engine and riding?
Either one will work you can also use loctite . I have never had one leak even after riding right after the assembly.
Not encludin shipping. $$$$ that's a killer.
This dude is awesome
Thanks!
Was there a noticeable loss of torque with the pipe? I was wondering if the 0-30 times were slower.

Hey i'm looking to get into mini bikes and not sure what parts to get i tried to use the links in the description but all of them were out of date if you could update them I would appreciate that so much!
I’m curious as to what kind of mileage the bikes get as they get modified too! Mpg stock then mods…..im thinking they might actually improve! It might be easier to check the mileage by quart than mileage per gallon…save you some time! You could rig up a small tank and just hang it on the frame with a hook and baling wire with a piece of clear fuel line…..what do you think? I’ve always wanted to know how far these minis could go on a tank anyway!
I did do a range test video a couple of years ago with a very small tank. Check it out.th-cam.com/video/j7U_0GgGLng/w-d-xo.html
@@Black66 so that little tank went 15 miles and it held .wq
Held .21 gal so it got 75 mpg….I always wondered. As the mods are installed, I would think the mileage would go down, but how much. Reason I’m asking is in case of an EMP, these minis might be the only thing we could get around on! And I wonder if the electronics would survive the pulse, cause the electrics are so rudimentary and still very robust. Thanks for getting back to me. I’m thinking about building my own bike adult size kinda like the groundhog. I’m sure you’ve seen it on utube. Comfort would be much improved for adults on a bigger bike. I love watching your builds and thanks for your exportice on the subject, and appreciate you taking the time to share your knowledge.
Would recommend checking and clearing big end rod clearance too-its often tight. I wonder how it would react to at least 1 stamped 1:1.3 rockerarms - plenty cheap. Oops my bad
Hey black! Just fyi. I got an oko $20 flat slide carb from Amazon and put it on my ct200u. It’s stock with a header. This carb is great! Came with main and slow jets also. I think it might be better than my mikuni??
Ah sweet! I'll have to try one out
Do you have a link for that? I would like to check that out.
@@Deucealive75
@mklein5179 got a link for that carb is it a PWK style?
Excellent video. Good advice, clear demo, pacing and narration keep it interesting.
Suggest you mention the torques you're using, as well as valve clearance.
What were your sources for the various parts? Particularly interested in the cast aluminum flywheel. Thank you!
Thanks! I did leave some of the parts used in the build in description of the video
@Black66 Question: The flywheel you linked from studz racing, they claim it fits "Honda clone engines only" and not predator.. nut we see you using it here on a predator engine. Is there a difference in these two tapers, if so, what is it? And how did you manage to use the EC Flywheel? (looks like you cleaned yours up a bit too) I ordered one for my 212 predator and studz racing is giving me trouble about it!
Yes, the taper on the clone and standard 212 are slightly different. There are differences in opinion on using the clone wheel on a standard crank.
I have used them without a problem. I am not saying he is wrong, Other folks might have had diffferent experiences with this stuff than I have. I make sure to lap the wheel in with a good valve grinding compound before torqing the wheel.
@Black66 thank you! Eric from studz racing is telling me to return the flywheel and "just by the billet flywheel" but I'm building a cheap 212 here for a mini bike... I don't need $120 billet flywheel on a stock un-reinforced 212 block. Any tips for lapping the clone flywheel to the predator properly?
I use valve grinding compound and run the wheel back and forth until I get an even sanded surface on the crank as seen in the video.
Also there is a link in the video description for a vendor that sells this wheel with the same taper for the 212. His wheel has 28 degresss timing built in in case you don't want to use the offset keyway to advance the timing.
Nice video learned. For me that 5mph top end isn't worth making allot more noise imo. Unless the stock muffler doesn't really do much noise canceling any ways. I'd go the other way if I could get quieter muffler and lose some top end. Unless you live around country roads your not goin 50mph very much anyways. Likely get up to speed and slow down after a few seconds randomly.
seems to me if your going to build a cycle kart this stock 212 is the way to go considering how much the ghost motor and hop up kit is .its way more bang for your buck.
Check out the Ghost vs. Predator video. th-cam.com/video/1jZ9Kb1sclE/w-d-xo.html
I've been spreading the word about you, especially on Cars and Cameras. Cuz they got 1 million subs, and you should too.
Thanks for the support!
Great video ! You work fast! When putting the engines back together, could you mention what you torque the bolts and other small things like that so we can make sure engine is put together correctly. I'm a old newbie learning to work on small engines. Enjoying your content.
Thanks! I'll do that.
I would love to know how you get 50mph out of a stock predator! We have built around 10 bikes so far and i think the highest our speedo hit was 38mph. 50mph seems untouchable witjout upgrades. Maybe our gearing is just way off
Gearing is a big deal with these things. Too much gear and it will actually be slower even though on paper it says faster. Check out this video th-cam.com/video/xV8i59aGUao/w-d-xo.html
Well I bought everything on your list for my very first 212 build! Super stoked about this! I still won’t have anything to put it on, but I’m intrigued by the build itself. Sure will be one bad shelf engine untill I find something to put it on!
As long as you're having fun that's all that counts!! I would throw a sweet-looking blower housing on it. Like chrome or powder-coated blower housing so it will look even sweeter sitting on the shelf!!!👍
@@Black66 so the stock carb is trashed, I’m really not trying to spend a load on the Mikuni vm22, I’ve found a few other brands on Amazon, “knock off” would you say that would be ok for this cheap build? I’ve seen a few reviews and I’m not sure what to do exactly, some say the stock carb is better than the knock off? Would it be in my best interest to buy the stock one or knockoff. Unless you know of somthing better? Really appreciate the advise!
@@cheynejones9536 I use this kit all the time.
Not as good as the OG but for the money it works fine. www.ebay.com/itm/194358544642
to adjust the mixture screw on stock carb it says online tightening it makes it RICH loosening it makes it LEAN correct ??
Be nice to see what a modified stock muffler would do.
Di you do a sidecar build?
Did you ever do a video of zip tied governor and a header pipe? I bet that's pretty close to the same 58mph
Can you make a video like this on the predator 224 please thanks for the content
Given my weight, the fact that I want to ride on dirt and grass, and the minor hills of my terrain, I'd give up 20 mph worth of top end gearing for more torque and acceleration. Might keep the clutch alive too.
Go with the 2 clutches setup or torque converter...
Such great videos my friend.
Would lobe to see a step by step video on that table build.
Great video, I noticed that you got the bike up to 50mph only with the governor ziptied on a stock 212. I have a cc100x with a stage 1 predator 212 hemi(jetted carb, intake, pipe, ziptied governer) but it only does around 35 as its top speed. Could this be because I am using a 12t clutch with a 75 rear sprocket? If I changed the sprocket to a 50t would it get a higher top speed? Thanks
yes by changing the sprocket to a 50t it will increase the speed
i would try a 60t first tbh
Hey, just a tip, a large reason the stock rod blows up on the 212 is due to not enough oil entering the linkage with the crankshaft. Maybe drilling a hole on the conrod would allow oil to seep into it, giving it similar lubricating properties as the billet rod.
Do you have a Baja hawg ty mini bike? They are pretty cool
Hello, thank you for the video. I was wondering if you could share which tools you use to port the head. Thank you
The porting tools I used are in the description of the video. Thanks for watching!
@@Black66 thank you
@Black66 just for reference you used a dermal correct?
How did you hook up the throttle back together because I tried following your video for the governor removal and now I’m stuck on how to hook up the throttle
Watch the latest B200 videos . I show how to make up a throttle without the Governor. th-cam.com/video/CK4p-iYTwFg/w-d-xo.html
Where did you get that lift?Diy? Do you have plans for it?love it
I bought it used. Not sure what store it came from. I use it for my minibike TH-cam channel. Thanks for watching. th-cam.com/channels/x9Ph4--sJxfQPzk_oEq8-g.html
Hey could I fit a stock 212 pred into a FRP DB003 40CC 4-Stroke
Hey, I'm 14 and I want to get into building my own first minibike! I will go with the 212 predator engine but I am having trouble finding a good budget frame!
and I was wondering if you could link the frame you are using in this video. Is the frame purchasable by itself?
thank you.
I think it would be great if you make a new budget build minibike because all the parts shown don't exist anymore
Keep up the great work I love your vids so far!
This was really cool video. Really like budget builds. Cool trick with the rod polish I’ve never seen or heard of that before. How much safer you think that makes a stock rod on the predator?
Thanks! Not sure on the rod. It was an old racers trick that has been used for ages. I would have to do a test or comparison on it to find out for sure .
I was wondering how much valve clearance is in a non hemi predator engine. I am building my first motor and I bought a cam from go power sports. It is the 265 hot cam, I am thinking of mating it with the 1.3 rockers you are using in this video however I don't want valve clearance to be a issue. Thank you for your time.
A standard predator is easier to use higher lift cams in because the valves are not angled or canted. If you use around .080” piston to valve clearance and .030” piston to head you should be fine.
Great video
Thanks!
What do you torque everything too?
Foot pounds duh 😎
Hey @Black66 how did you make the crank holding tool?
I made it from an old clutch . You can buy the tool already made on the mini bike web sites like GPS.
I would like to see this run with a carb upgrade aswell
Hello , another great video . I assume this flywheel would work on the predator 224 , same taper ? Was it a good fit , seemed it rocked back and forth a bit before you torqued it down ?
Yes, It will work on the 224. The reason it rocked back and forth was the 7 degree flywheel key . It lets the flywheel move so you can rotate it forward to get the 7 degrees of additional timing.
What type of wheels did you use and what was the back wheel setup? Im looking to make one of these, but dont know what tires to use.
Check out the mini bike playlist. I have had a few different set ups on this bike th-cam.com/video/5Grizcea_Ug/w-d-xo.html

Good consistent data comparisons. Can you list the vendor where you picked up the cast aluminum flywheel for that price?
Thanks Yes, the links are in the description
Love your videos! What brand pipe is that you added?
Thank you! The links are in the description for the parts used in the build.
I just received my stage 3 header pipe from gopowersports for my 224 and it doesn't fit? Neither the gasket or the flange... did you have these problems when using some of your 212 exhausts?
If you watch the 224 playlist you will see, I changed out the head at some point in the build. You can use them . You have too oblong the holes with a Dremel or file.
@@Black66 I noticed you used one thats why I was so confused. I must've missed you dremeling the holes
Are you going for the spring mini bike run? Yes, I'm local. We share the same city.
Ya, I might go
Do you have a video on the throttle connection to the carb with no governor
Yes, the throttle connection is covered in this video and many others on the channel th-cam.com/video/bXRQfwHEPfg/w-d-xo.html
@@Black66
Your awesome ... You reply fast my friend
So you want your timing key out of the way from the groove behind where you installed yours? Like if put the back end of my timing key flush with the groove behind it then would I'm good?
