That stabilizer I agree is a must. I have a headlight on the front added to mine and the front end definitely gets a bit wild at top speed. I just hold on tight and hope for no death wobble 🙃
No joke…you could try raising your fork height a bit, you’ll lose a little handling in corners but your front end won’t walk on ya 🤷🏼♂️ unfortunately it’s a balance between handling and stability…personally I steer with my throttle so I jack them bitches up 👍
Yeah I got them as raked out as they can be 🙃 I definitely feel it in the tight turns, but like you said the throttle is what makes the bike turn around quick. As you know the 426 spends most of its time going fast so I don’t mind losing some stability on the turns if itll keep things “safe” wide open lol 👍
Hey mate I've got an 01 wr426 would that decomp lever work on it? I figure it would so would you have a link to it I'd love to get it so I don't blow my engine up if I hit a branch or something
Pezza no problem and yes it’s for the Honda hot start but it fits the Yamaha perch just fine, the only thing to be concerned about is how worn out your cable is. Mine was shot and I couldn’t depress the lever easily...keep in mind it’s still a tiny bit harder to push over the stock lever however with gloves and a mans hand you should have no problem
@@localenterprisebroadcastin5971 alright sweet I'll get it ordered! Thanks for the help, I'm super keen to get the bad boy ready for the bush it's an absolute GUN of a bike
I have an 02 426 WR with the hotcam exhaust cam mod that eliminates the manual decomp. I’ve got the carb throttle stop corrected, did the exhaust cam yz timing mod, yz ignition timing wire change and love the power. It’s strong smooth power. Love the 18” rear rim coupled up with an IRC M5B 140/80/18, makes a killer rear tire.
Awesome bike just got me a 2001 yz426 street legal but needs major love. need to rebuild bottom and top end. Pretty much replacing everything. I’ll post videos soon.
Fuck yeah! Throw some good parts at her and let it rip ! I recommend the 13.5:1 piston ...both hot cams and a good head polish ...that thing will be a rocket 🚀...look forward to seeing your videos and thanks for the sub...If you run into any issues feel free to drop questions in my comments section. I’ll answer as soon as I can 👍

Got mine on Amazon but I have since moved to the Magura hydraulic…it was around 250 bucks but well worth it …I too had to customize the easy pull box to work…after about a year I noticed the shorty cable was stretching and wasn’t disengaging my clutch properly
Hey man, im considering picking up a 2001 YZ426F and ive been told that they have problems with valves and they are quite hard to start. Is that true? How is your 426 going?
Sick bike, I had an 02 back in the day. One of my favourite bikes ever, & I’ve had a stack of bikes, still got em. If you find 1 in good condition, grab it straight away. Just service it, change the oil every 5-10 hours, you’ll have no drama’s. How I recommend you start it, is to kick it over as far as the kickstart goes, take it up all the way, push decomp lever in, kick it a quarter way, come back up to full stroke, ( kickstart at its highest point ) , let go of decomp lever & give it a filthy ol kick. Start every time.
@@peterdalmationcro4217 thanks for the reply man! I ended up getting the 426 about a month ago now although it ended up being a 450 but I still got it and I absolutely love it, I absolutely love the pre aluminium frame YZ's
Good question 👍 it’s so I know I’ve properly torqued the fastener to factory specs and tell me if certain fasteners comes loose. It’s a trick I picked up wrenching in the military
Yeah that seems perfect. I have 15/48 currently because I’ll be mixing in some street riding going from trail to trail. I’d like the 14/48 better power wise, but for the street it would prefer the little wider ratio. When I had the engine apart I wish I had thought of putting a wr transmission in there. Or at least just the 4th and 5th if that’s possible
@@frankiemarchese2978 right!??

@@frankiemarchese2978 the funny thing is my bike has been built and has no problem passing the new bikes on the track...probably because I’m not hauling around a big stupid heavy starter, battery and electric fuel pump...I remember when the 426 was considered “heavy” ...shit most new bike out weigh it by a good 10-15 lbs 😂😂😂
Yeah no joke, they designed it to feel like a 250 2 stroke and they did a good job. I’ll look into those cams one day. For now im happy with the oem motor.
Yes ...when you like to wrench on the weekends and beer is involved it’s a good idea to mark the fasteners you’ve already torqued properly 👍 it’s easy to miss bolts when they’re all the same color 😉
Yehudi Marin shit I did forget that... I’ll update the description in a day or so...check back at the end of the week ...thanks for the view and the comment 👍
Trey Swingo for the easy starting yes. Just the exhaust is all you need, but if you want increased performance getting both is the best option. A shim kit is required for both. I got lucky and only needed to shim my intake but it’s good to have a kit around if you plan on keeping the bike for a while. The valves do need to be adjusted periodically with shims, having the kit keeps ya from making several trips to the shop for one or two shims
@@treyswingo9079 It can be a bitch and its gonna be a while before i have to tear it down again, in the meantime here's a helpful vid for ya th-cam.com/video/55FsTP3JLaQ/w-d-xo.html
Can you link the lever and perch’s as well I like the the decompression lever turned 180 degrees I was worried about it being pushed while riding and I like the set up you have
Chase Jenkins I know the front fender can be swapped with the new ones and rumor has it that the 450s with the steel frame plastics fit and are lighter
Got an 01' yz426. The bike's a beast and distinctive sound is unmatched. At a minimum, throw in the hotcams exhaust cam...you'll thank yourself later.🥵
Couldn't agree more, if you watch the full video I did cam the motor and ported the head... you'll hear that sound. 7:50 Thanks for the comment and keep that front wheel flying boss!
The two best mods we did to all of our 426s(2) & 400s(3) are 05 yz450f carb & hot cams decomp set up, bikes crank so easy I can kick them over with no problem, great bikes !
Picked up a 2001 a couple weeks. Awesome power to ground ! At 55 yrs old, this is a blast !! Several mods from prior owner, and adding more now. GREAT BIKE !!
Bikelife Mikey The lever you speak of is called the decompression lever, stock motors require one, I do have one but I don’t need it to start because of the updated exhaust cam. I highly recommend that modification 👍
Yeah they can be a bitch to start if there not set up right, first thing is a richer pilot jet, then check your valve lash, rarely is it an ignition issue but it can be, make sure the plug is new and the flywheel is clean of debris... other than that these bikes are reliable as fuck
I tell ya what once it's up and going its awesome! I was rippin around yesterday once the bike is warm it starts right up it's that first Initial start.
Austin Werner MX thanks for the comment 👍 good luck with your super moto build and to answer you question it’s so I know I’ve torqued the bolt properly after re-assembling major components...a trick I learned from wrenching in the military...but a lot of race teams do it as well
Austin Werner MX copy this part # R132100013 into amazon and it will bring it up...it’s been updated in design since I last purchased mine...be advised though my decomp cable is brand new so it’s not much effort but if your cable is worn or old you might need a strong thumb 👍
Hi Austin, super moto conversion done ? how does it feel like riding on streets? as an MX bike it should have close loop clutch gearing right ? how many gears does it have ?
I am from Austria and I have been looking for something like this but i cunt find such a thing in my country😅 Therefore I would be very greatful if you could send me a link from this thing😅😂🙈
Rocky mountain High riders well there’s a few options...the easiest way is install a rechargeable cordless drill battery to the underside of your seat (in the air box area) ...that should give you a few hours of lighting if you’re using LEDs...the other option is to find a stator & flywheel off of one of the WR models or buy the 500 dollar conversation kit from “Ricky Stator” (a damn good stator shop based outta California) ...unfortunately with these 426s Yamaha only gave ya enough juice to run the ignition ...if you’re planning on racing in the super Moto I would go with the cordless battery set up ...a larger stator for lighting completely robs the engine of power and the heavier flywheel will slow the revs significantly compared to stock...
@@localenterprisebroadcastin5971 hey thanks for the tip ive been looking at the stator and flywheel option to be able to run lighting I'm planning on getting my 426 street legal do you know If there is a kit that makes this a pretty simple conversion
I've owned 7 of these bikes. By far one of my favorite bikes, but the best mod would be a auto decompression cam from a 2003 yz450f or a Hotcam. Also a 450f carb.
Hello I have put comments and questions on one of the first videos when the bike was first bought with some good feedback and helpful hints but now I have another BIG PROBLEM! I got all my parts in and ready to be installed in my motor I got new valves and springs from kibblewhite! I got both exhaust and intake hotcams camshafts I got new connecting rod and piston kit, performance ignition coil, a complete transmission bearing and seal kit, 2 complete engine gasket kits just incase, counter balancer bearings and shaft, water pump rebuild kit and shaft, timing chain, tensioners, on and on I have over a 1000$ invested!!!! I have everything to make this old bike new again! Now I start to tear down the motor pulling the valve cover and then the cams and what do I find the journals on the intake side where the camshaft rides in is badly worn I can clearly see mushrooming and that's not good!!! I obviously can't put all my new parts in with it being like that!!! So what do I do! I looked around online i found a refurbished YZ426F head for 750$ but its complete with new everything including stock cams! I just spent all that money I may just buy this head so I have it but I want my head redone as well! WHO CAN I SEND IT TO FOR THE MACHINE WORK TO BE DONE????? i found several other heads online used and they want BIG$$$$ for them and basically they could be junk then I'm more screwed! I no I saw a few with the same problem and the seller says there in good shape some of the pictures I see don't even show the journals I think they are hiding something! And the ones I do see the journals they look as if they too are wore out! It's all a crap shoot! So if anyone can point me to a solution I'd be much appreciative! Because I am freaking out over this!!!!!🤢🤮😤🤬 This bike may end up being a big money pit with no happy ending!
Allen Stayduhar ok i understand your frustration. When it comes to machine work I always go local. But machine work isn’t necessary...sometimes with the older bikes it’s cheaper to buy a parts bike to go with with it 🤷🏼♂️. I say keep looking...I’m sure you’ll find a head that works ...FYI I ALWAYS do my own porting and head work hence my disclaimer “if you do t like working on shit don’t buy this bike” ....keep looking for a used head and buy a dremel 👍
@@localenterprisebroadcastin5971 I think that finding a parts bike is a wise idea I have been hoping to find a WR rather than a YZ so I can get the lighting coils and flywheel off the bike and use it on mine! I will definitely check out that video with porting I've always wondered how that works I've done 2 strokes but this is my first rebuild of a 4 stroke motor!!! Its all a new learning experience for me! Out of all the videos I've seen yours has been very helpful! Thanks again I'll definitely keep you updated!
Hey bud it's been awhile since I've messed with my 400 project! So I took the bike apart I have everything I need except for the head problem but I got a good used head now and I got it all rebuilt! All new internationals valves springs cams I put both exhaust and intake hot cams in it awaiting my shim kit! The only problem I'm having now is my cylinder itself there is very little wear in the cylinder although I can feel a slight difference when I put the old piston back in the bore. there seems to be a lot of play or a very large gape. I put the rings back on the piston and placed it back in seems to be very tight however it rocks side to side? So I dont know if I should have the cylinder chromed or my other option is a steel sleeve? The old piston is junk because the wrist pin is scored up slightly and there is a very little bit of play on both ends of my connecting rod which I put a new rod kit in it already! So question do I get a forged piston or a cast piston I know and understand that a cast piston can be weaker I also no that a cast piston doesn't expand as much as a forged piston does? Maybe this is why there seems to be a lot of room to allow for expansion to happen I also wanted to know and pick your brain if I go with a steel sleeve bore what kind of piston should I use? I'm fairly sure the rings are a different material then ones used in a chromed bore piston? And the reason I ask is I am looking into buying a cylinder that has been sleeved and bored to fit a 426 I imagine the heads are the same from a 400 to a 426 I was also curious about what compression ratio should I use? This is still all very new to me i never wrenched on a 4 stroke bike like this b4 there are so many variables to worry about! I do enjoy working in bikes though it's not a bother at all I just dont want to make any serious mistakes! I dont wanna do it twice and spend more money! If you can appreciate that! Once again I so greatly appreciate your help and input on my project! I hope I can send a video somehow when it's all done! Thanks a million! Ill be looking for your input!
I also was wondering where to buy one of those steering stabilizers you have on your bike? That is a definite upgrade I need to do! I've never felt a bike jolt side to side like that in the front like this one did on gravel at high speeds! Even older bikes I've had! I suppose its possible my steering stem is lose but I doubt it!
Total investment so far around is 2800 to 3000 bucks including purchasing the bike...keep in mind i blew this bike up once already (my fault) so I should be $650.00 to 800.00 bucks less...most of my expense was on the cams. I got most of my performance increase from the head work, carb mod and high compression piston, pretty much a budget build .
Lewis Z I already did 👍 ...here’s the link ... th-cam.com/video/AOOSAl3bPDo/w-d-xo.html. Keep in mind that was my first attempt at it I have since relocated the lever to the throttle side
Yeah I ver happy with that clutch set up. Its light as a feather and grabs like no other. I ran it down in california with 0 issues. Motor was making the most it ever had at that elevation and still no slip
@@localenterprisebroadcastin5971 nice can't go wrong with steel clutch plates and more durable especially if you like to shift constantly. I will do the same set up great add on
Do you have a link for the hot start lever on your right side of the bike. I bought my bike used recently. It has a full set of hot cams but the lever for it is red right next to the choke. it is such a pain to constantly have to reach down to pull it out and then push it back in after firing the bike. I would greatly appreciate if you have a link that you could share for a lever like yours. Also if you have a link for the steering stabilizer you use I would be interested in that as well
Realize this video is older but wanting to know what shift lever you are running? I hate the stock one, to get it where I need it to be I cannot fully seat the splines without it rubbing the case. Thanks
Jeremy Kyle I’ve had similar issues even with my aftermarket one ...but it’s an MSR shift lever...i had to bend it slightly to be where I like it. I don’t have the part number as it was equipped with the bike when I bought it...having said that it seems to working very well and has taken plenty of punishment 👍
Albe's Adv thanks bud👍 I look forward to seeing your bike evolve as your riding needs change. I’ll be in the SoCal area (mainly Temecula) later this year we should shred some hills if ya got time 🤷🏼♂️
So I can stall my bike but just flicking the throttle from idle to 1/16th throttle just like 3mm of movement in the slide really fast and it will stall, if I gun it it will rev up fine, any way to get rid of that small small bog
Also you need to rule out any vacuum leaks before the carb...This could be done quite easily with a handheld propane torch, With the engine at idle point the propane torch around the intake of the engine (Obviously without the flame lit) If your engine RPM changes that you know you’ve got a vacuum leak somewhere...To isolate the vacuum leak use soapy water mixture in a spray bottle and spray around the intake where the suspected leak maybe...And a vacuum leak Cause bubbles to form when you go to the throttle
Check the mid body gasket on the carb and check the throttle slide for excessive wear (the carb body may be worn as well,The telltale sign of this is the infamous wandering Idle when warm)...Also Excelerator pump timing can be the culprit...You may be experiencing a Rich bog instead of a lean bog if you’re leak jet isn’t correct or you don’t have one (like my carb) ...The good news is the FCR carburetor can be tuned it just about every throttle position
That stabilizer I agree is a must. I have a headlight on the front added to mine and the front end definitely gets a bit wild at top speed. I just hold on tight and hope for no death wobble 🙃

It's not gonna have a fuel pump fuel injection computer module sensor electronic junk problems. 1998 - 2006 steel frame carbureted titanium 5Valve Yamahas ARE THE BEST!
Do you just need one hot cam?
Trey Swingo for the easy starting yes. Just the exhaust is all you need, but if you want increased performance getting both is the best option. A shim kit is required for both. I got lucky and only needed to shim my intake but it’s good to have a kit around if you plan on keeping the bike for a while. The valves do need to be adjusted periodically with shims, having the kit keeps ya from making several trips to the shop for one or two shims
local enterprise broadcasting in the future could you do a video for that?
@@treyswingo9079 It can be a bitch and its gonna be a while before i have to tear it down again, in the meantime here's a helpful vid for ya th-cam.com/video/55FsTP3JLaQ/w-d-xo.html
link to the kickstand?
Chase Jenkins www.rockymountainatvmc.com/parts/ricochet-kickstand-p
Chase Jenkins use thread locker on the bolts if you buy one
Can you link the lever and perch’s as well I like the the decompression lever turned 180 degrees I was worried about it being pushed while riding and I like the set up you have

Anyone know of a resytle plastic kit for the 02?
Chase Jenkins I know the front fender can be swapped with the new ones and rumor has it that the 450s with the steel frame plastics fit and are lighter
I have my '01 YZ426 since 2004. I will literally never sell it. It is a beast of a bike!
Josh Danco I don’t blame you one bit 👍 I’m never selling mine either
@@localenterprisebroadcastin5971 where did you order the clutch/decomp combo lever from?
have u rebuilt it
So I have the same black box right above the radiator on the right side what is that ?
Brock Maurer it’s the CDI module. It’s part of your ignition system
Got an 01' yz426. The bike's a beast and distinctive sound is unmatched.
At a minimum, throw in the hotcams exhaust cam...you'll thank yourself later.🥵
Couldn't agree more, if you watch the full video I did cam the motor and ported the head... you'll hear that sound. 7:50 Thanks for the comment and keep that front wheel flying boss!
I watched the full video. Great job; she's purty!....keep her thumpin'!
The two best mods we did to all of our 426s(2) & 400s(3) are 05 yz450f carb & hot cams decomp set up, bikes crank so easy I can kick them over with no problem, great bikes !
Rhonda Palmer there are many mods to make this bike even better but you have highlighted the two most important 👍
Yeah, after being a 2t family for years we picked up out first yz400f back in 08 & those upgrades really bring the older bikes up to par.
Is the kick stand strong enough to be able to kick the bike over with me standing on the bike fully?
Brandon Nguyen I’m sure it depends on how heavy and tall you are 🤷🏼♂️ I weight bout 190 and it holds me just fine 👍
Picked up a 2001 a couple weeks. Awesome power to ground ! At 55 yrs old, this is a blast !! Several mods from prior owner, and adding more now. GREAT BIKE !!
David Newton thanks for the comment 👍 yeah they’re a blast for sure and an absolute beast in torque
What did it cost you?
@@rickydicky5889 I just bought one for 1200 😂runs & rides & has sumo wheels & dirt setup.
I have a 01 426f I have a lever I have to hold and release when I kick why don’t you have one?
Bikelife Mikey The lever you speak of is called the decompression lever, stock motors require one, I do have one but I don’t need it to start because of the updated exhaust cam. I highly recommend that modification 👍
local enterprise broadcasting ohhhh okay
Bikelife Mikey He literally talked all about it in the video lol.
Just got one of these definitely need to get some of these mods because kicking it is a bitch after a while lol
Yeah they can be a bitch to start if there not set up right, first thing is a richer pilot jet, then check your valve lash, rarely is it an ignition issue but it can be, make sure the plug is new and the flywheel is clean of debris... other than that these bikes are reliable as fuck
I tell ya what once it's up and going its awesome! I was rippin around yesterday once the bike is warm it starts right up it's that first Initial start.
Where can I find that seat?
Robert Pacheco Amazon...but that was last year...I don’t know if it’s still available...eBay also had it but it was more expensive
Nice bike, i just got one thats street legal and im doing a supermoto build. Why are your bolts painted orange
Austin Werner MX thanks for the comment 👍 good luck with your super moto build and to answer you question it’s so I know I’ve torqued the bolt properly after re-assembling major components...a trick I learned from wrenching in the military...but a lot of race teams do it as well
local enterprise broadcasting ah ok thats a good idea, also where did u get the clutch/decomp lever combo. Couldnt find it
Austin Werner MX a paint marker is your best friend especially after a few beers and chief 😉
Austin Werner MX copy this part # R132100013 into amazon and it will bring it up...it’s been updated in design since I last purchased mine...be advised though my decomp cable is brand new so it’s not much effort but if your cable is worn or old you might need a strong thumb 👍
Hi Austin, super moto conversion done ? how does it feel like riding on streets? as an MX bike it should have close loop clutch gearing right ? how many gears does it have ?
Pound reducer clutch link? Pls😅😅
Objectively hilarious 😂 It’s cheap but it works🤷🏼♂️
I am from Austria and I have been looking for something like this but i cunt find such a thing in my country😅 Therefore I would be very greatful if you could send me a link from this thing😅😂🙈
Looking some good ideas for a supermoto build on my yz426f
Rocky mountain High riders cams carb and a good head polish w match porting and I promise you won’t be disappointed 👍
@@localenterprisebroadcastin5971 what's the easiest way to run lighting to be able to make street legal?
Rocky mountain High riders well there’s a few options...the easiest way is install a rechargeable cordless drill battery to the underside of your seat (in the air box area) ...that should give you a few hours of lighting if you’re using LEDs...the other option is to find a stator & flywheel off of one of the WR models or buy the 500 dollar conversation kit from “Ricky Stator” (a damn good stator shop based outta California) ...unfortunately with these 426s Yamaha only gave ya enough juice to run the ignition ...if you’re planning on racing in the super Moto I would go with the cordless battery set up ...a larger stator for lighting completely robs the engine of power and the heavier flywheel will slow the revs significantly compared to stock...
Rocky mountain High riders here’s a link for the easier way to ad lights th-cam.com/video/lQfM68Ry3xw/w-d-xo.html
@@localenterprisebroadcastin5971 hey thanks for the tip ive been looking at the stator and flywheel option to be able to run lighting I'm planning on getting my 426 street legal do you know If there is a kit that makes this a pretty simple conversion
2001wr426 have 1 a beast 👍🏾👍🏾
I've owned 7 of these bikes. By far one of my favorite bikes, but the best mod would be a auto decompression cam from a 2003 yz450f or a Hotcam. Also a 450f carb.
Haha bought mine last year with a hot cam and a decompression valve started up after the 6th kick after sitting all winter
Just picked one up today it’s a beast! One of the most underrated bikes out there
agreed
Hello I have put comments and questions on one of the first videos when the bike was first bought with some good feedback and helpful hints but now I have another BIG PROBLEM! I got all my parts in and ready to be installed in my motor I got new valves and springs from kibblewhite! I got both exhaust and intake hotcams camshafts I got new connecting rod and piston kit, performance ignition coil, a complete transmission bearing and seal kit, 2 complete engine gasket kits just incase, counter balancer bearings and shaft, water pump rebuild kit and shaft, timing chain, tensioners, on and on I have over a 1000$ invested!!!! I have everything to make this old bike new again! Now I start to tear down the motor pulling the valve cover and then the cams and what do I find the journals on the intake side where the camshaft rides in is badly worn I can clearly see mushrooming and that's not good!!! I obviously can't put all my new parts in with it being like that!!! So what do I do! I looked around online i found a refurbished YZ426F head for 750$ but its complete with new everything including stock cams! I just spent all that money I may just buy this head so I have it but I want my head redone as well! WHO CAN I SEND IT TO FOR THE MACHINE WORK TO BE DONE????? i found several other heads online used and they want BIG$$$$ for them and basically they could be junk then I'm more screwed! I no I saw a few with the same problem and the seller says there in good shape some of the pictures I see don't even show the journals I think they are hiding something! And the ones I do see the journals they look as if they too are wore out! It's all a crap shoot! So if anyone can point me to a solution I'd be much appreciative! Because I am freaking out over this!!!!!🤢🤮😤🤬 This bike may end up being a big money pit with no happy ending!
Allen Stayduhar ok i understand your frustration. When it comes to machine work I always go local. But machine work isn’t necessary...sometimes with the older bikes it’s cheaper to buy a parts bike to go with with it 🤷🏼♂️. I say keep looking...I’m sure you’ll find a head that works ...FYI I ALWAYS do my own porting and head work hence my disclaimer “if you do t like working on shit don’t buy this bike” ....keep looking for a used head and buy a dremel 👍
@@localenterprisebroadcastin5971 I think that finding a parts bike is a wise idea I have been hoping to find a WR rather than a YZ so I can get the lighting coils and flywheel off the bike and use it on mine! I will definitely check out that video with porting I've always wondered how that works I've done 2 strokes but this is my first rebuild of a 4 stroke motor!!! Its all a new learning experience for me! Out of all the videos I've seen yours has been very helpful! Thanks again I'll definitely keep you updated!
Hey bud it's been awhile since I've messed with my 400 project! So I took the bike apart I have everything I need except for the head problem but I got a good used head now and I got it all rebuilt! All new internationals valves springs cams I put both exhaust and intake hot cams in it awaiting my shim kit! The only problem I'm having now is my cylinder itself there is very little wear in the cylinder although I can feel a slight difference when I put the old piston back in the bore. there seems to be a lot of play or a very large gape. I put the rings back on the piston and placed it back in seems to be very tight however it rocks side to side? So I dont know if I should have the cylinder chromed or my other option is a steel sleeve? The old piston is junk because the wrist pin is scored up slightly and there is a very little bit of play on both ends of my connecting rod which I put a new rod kit in it already! So question do I get a forged piston or a cast piston I know and understand that a cast piston can be weaker I also no that a cast piston doesn't expand as much as a forged piston does? Maybe this is why there seems to be a lot of room to allow for expansion to happen I also wanted to know and pick your brain if I go with a steel sleeve bore what kind of piston should I use? I'm fairly sure the rings are a different material then ones used in a chromed bore piston? And the reason I ask is I am looking into buying a cylinder that has been sleeved and bored to fit a 426 I imagine the heads are the same from a 400 to a 426 I was also curious about what compression ratio should I use? This is still all very new to me i never wrenched on a 4 stroke bike like this b4 there are so many variables to worry about! I do enjoy working in bikes though it's not a bother at all I just dont want to make any serious mistakes! I dont wanna do it twice and spend more money! If you can appreciate that! Once again I so greatly appreciate your help and input on my project! I hope I can send a video somehow when it's all done! Thanks a million! Ill be looking for your input!
I also was wondering where to buy one of those steering stabilizers you have on your bike? That is a definite upgrade I need to do! I've never felt a bike jolt side to side like that in the front like this one did on gravel at high speeds! Even older bikes I've had! I suppose its possible my steering stem is lose but I doubt it!
How much you spend on it all?
Total investment so far around is 2800 to 3000 bucks including purchasing the bike...keep in mind i blew this bike up once already (my fault) so I should be $650.00 to 800.00 bucks less...most of my expense was on the cams. I got most of my performance increase from the head work, carb mod and high compression piston, pretty much a budget build .
Sick set up I want the same for my bike
Could you make a list of the added on parts
Could you do a hot start video and go over the issues associated hit the hot start?
Lewis Z I already did 👍 ...here’s the link ... th-cam.com/video/AOOSAl3bPDo/w-d-xo.html. Keep in mind that was my first attempt at it I have since relocated the lever to the throttle side
Nice job on the tusk steel plates, too choice
Yeah I ver happy with that clutch set up. Its light as a feather and grabs like no other. I ran it down in california with 0 issues. Motor was making the most it ever had at that elevation and still no slip
@@localenterprisebroadcastin5971 nice can't go wrong with steel clutch plates and more durable especially if you like to shift constantly. I will do the same set up great add on
Do you have a link for the hot start lever on your right side of the bike. I bought my bike used recently. It has a full set of hot cams but the lever for it is red right next to the choke. it is such a pain to constantly have to reach down to pull it out and then push it back in after firing the bike. I would greatly appreciate if you have a link that you could share for a lever like yours. Also if you have a link for the steering stabilizer you use I would be interested in that as well

Realize this video is older but wanting to know what shift lever you are running? I hate the stock one, to get it where I need it to be I cannot fully seat the splines without it rubbing the case. Thanks
Jeremy Kyle I’ve had similar issues even with my aftermarket one ...but it’s an MSR shift lever...i had to bend it slightly to be where I like it. I don’t have the part number as it was equipped with the bike when I bought it...having said that it seems to working very well and has taken plenty of punishment 👍
@@localenterprisebroadcastin5971 Thank you
Jeremy Kyle thank you for watching and I hope your beast stays strong 💪
well done, you gave me a few good ideas 👍
Albe's Adv thanks bud👍 I look forward to seeing your bike evolve as your riding needs change. I’ll be in the SoCal area (mainly Temecula) later this year we should shred some hills if ya got time 🤷🏼♂️
local enterprise broadcasting sounds good, shoot me a message when you are around and if I’m not working we’ll definitely have to go ride
Albe's Adv sounds good bro 👍 we started our projects around the same time it’d be fun to put em up against one another 🤔
Do not listen to these 2 spam post above me ^^^^
I see them everywhere... The exact same post word for word
They usually joined YT the same day, or a day or 2 apart
So I can stall my bike but just flicking the throttle from idle to 1/16th throttle just like 3mm of movement in the slide really fast and it will stall, if I gun it it will rev up fine, any way to get rid of that small small bog
Also you need to rule out any vacuum leaks before the carb...This could be done quite easily with a handheld propane torch, With the engine at idle point the propane torch around the intake of the engine (Obviously without the flame lit) If your engine RPM changes that you know you’ve got a vacuum leak somewhere...To isolate the vacuum leak use soapy water mixture in a spray bottle and spray around the intake where the suspected leak maybe...And a vacuum leak Cause bubbles to form when you go to the throttle
Ok for some reason my first response didn’t go through
Check the mid body gasket on the carb and check the throttle slide for excessive wear (the carb body may be worn as well,The telltale sign of this is the infamous wandering Idle when warm)...Also Excelerator pump timing can be the culprit...You may be experiencing a Rich bog instead of a lean bog if you’re leak jet isn’t correct or you don’t have one (like my carb) ...The good news is the FCR carburetor can be tuned it just about every throttle position
