2001 YZ426F Project - Bringin' Back The Thump!

This is a Yamaha YZ426 motocross dirt bike that I bought on a whim. It was not running, and showed major signs of neglect. The video shows the procedures I used to get it running again. I also talk about some of the repairs and restoration steps that I plan on completing.

[@tomnolen9261]

I got a lot of strange looks every time the neighbor sees me with one boot and one house slipper on and I'm usually mad as hell and sweating walking around in circles cussing a bike. Some people may think I'm crazy.

[@LamzLamz714]

Hahaha then u start getting a mean cramp on ur kicking leg and the bike still hasnt started...thats when u kick the bike on its side from frustration...lol

[@kyferez1]

Replace the exhaust cam with HotCams with autodecompression and make sure valves are in spec. I also did the bog mod on the carb, and give it 2 good rotations on the throttle to get the fuel pump to spray in some gas, pull out the choke, and I can crank my 01 YZ426f in 3 or 4 kicks every time when cold.

@@OfficialRingWurmRacing how'd your bike build go bud? I was 10 years old when I got my first bike which was a 25 year old 1980 Honda cr80 at the time for 100 bucks with a blown top end. Me and my dad got it running and I loved that bike so much. A few years later and new bike I started racing motocross and cross country. I miss those days alot and to this day I regret ever getting rid of that thing. I'd love to do a restoration on it now that I'm older.

Jetting from factory was off. My bone stock factory 2000 426 came with jetting combo that wasn’t on the jetting chart

[@MrRe1107]

Just some advice... When you have a bike that hasn't been started in that long, First thing you should do is buy a new spark plug, No matter how nice it looks. Get some fresh oil and a filter that's specific for the bike you have. Drain the coolant and flush the radiators and put some fresh antifreeze in it. Drain whatever's in the gas tank and get some fresh super gasoline. Clean and oil/ Buy a new air filter. Take the carb apart and thoroughly clean it. And never hold the throttle wide open when kicking a 4 stroke. Glad u got it to run thou. Be safe out there riding man!

[@brock12892]

Man, I'm really wanting a dirtbike. I haven't had one since I was like 13 and it was a small under 100 cc yamaha or honda 2 stroke. I Bought a Raptor 700 quad few months back and I am kind of regretting not getting a bike instead... Cool video dude.

[@schlusselmensch]

Bought an '01 426 with a scattered engine and 4 boxes of 2 other engines in pieces. Glued it all back together (the rest of the bike was excellent fortunately). Tell you what, it accelerates my svelte 220 pound body most satisfactorily, to put it mildly. Two things; The Hot Cams decompressor setup is a wonderful thing and keeping the valves set properly is time well spent.

[@jenniesgarage]

thanks for the comment, and good job on your project. They do have some power (once started).

[@Alexander_l322]

This was 8 years ago 🤣

[@GhettoPaintball]

little late now but make sure to completely take apart your carb. after removing the bowl you will find 4 more screws on each corner that allows you to remove the mid section of the carb giving you access to a couple more jets. Make sure the carb shoots fuel into the engine when the throttle is opened up and hope your pilot jet is still set from factory.. if it still wont start check spark and timing.. Last but not least the 450 cam mod is a must have for these bikes.

Finally found a channel where i get insight on working on bikes

[@parttimelegend..9373]

RAYMOONDOE 215 I really feel the same way. I'm actually very good at this myself and I can spot "talentlessnes" from a mile away and this is the good stuff. There is allot of videos with people who think they are good enough to be teaching when they for a trained eye are are fooling senseless around. I think it is a product of having told that all they do is good by the parents mixed with a high degree of narcissism and the believer that they will be KZbin starts. It actually irritates something out of me because it can bring people who want to do a good job allot of headaches when all they do is trying to get knowledge and learn how to do it right. This guy is not trying too he is good. I will add that there are allot of other guys that are very skilled but they hide between allot of other " bad word" stuff.

[@rocc05rx8]

I had a 2000 yz426f. Thing was a great bike... when it started and your foot wasn’t bleeding and broken from kicking it for 45 min. Even got a hole in my work boots one day kicking it so much. A nightmare. Over all a great bike though. Load of power and great despite being a heavier bike.

[@psychotrucker9880]

A small touch of starter fluid works.

[@jenniesgarage]

Yes they are easy to flood. I've found the best way to clear it out is to hold it wide open with the decomp lever pulled and kick it through about 10 times.

To get the spark plug out you use a rubber hose that fits over the white part of the plug and you finish unscrewing it and pull it out with the hose .

[@GetYaShitTogetha]

Exactly, I only buy used cars, but very nice ones. I have a CL500 that cost around $90,000 when it was new. the previous owner put 89,000 miles on it and kept it in GREAT condition. He also knocked about $77,000 off of the price for me too! I got it for $13,200. I cant take $77,000 depreciation hits again and again so I stay out of the way and let it hit other people. I got my YZ426 for $850 and I love it too. I enjoy nice things but I enjoy them more when I get a killer deal.

[@swemx7403]

Oh boy i remember this bad boy. I had a yz426f from 2002. And holy sh*t it's a beast. The only thing i didnt like about it tho, was if you randomly stalled it and had to kick start it again in the forest.. good luck mate. If you dont have the power in you, it wont start. The end!

[@TurboNeon185]

we're spoiled these days. i just started riding again last year after being out of it since about 2005 and i jumped into auto decomp and fuel injection. i skipped over all the difficulties of starting 4 strokes. now if only they would put an auto choke on them. pulling that knob out is a real pain haha.

[@racksrus5137]

A lot of ppl don’t know that on the decompression lever you hold it in to have the pressure high and as you kick you release the lever as if your popping the clutch . The bike will start every time .

[@jondoe6618]

hey man nice vid I have watched your previous vids as well This one made me get my own project bike. I previously have owned a 98 yz400f and it was my favorite bike i have ever owned. I bought it back in 02 or 03. and sold it a few years later. But after watching this vid i found a nice bike that needed work.So i bought a 1999 yz400f for 300$.It didnt run.After about 20 hours and around 200$ it runs like a dream.So for 500$ i got a nice yz400f i am stoked.

[@Snitchy1989]

4 strokes can be an asshole to start, especially when hot. My old Honda CRF 450 took me over 20 kicks to get started at the side of a track, when it was hot! One of the many many reasons why i switched to 2 stroke a long time ago :D Easier starting for 1, and for 2... Doesnt require a bank loan to rebuild the engine :D

[@jenniesgarage]

I remember almost 20 years ago when all I had was 2 strokes. Easy and cheap to run. The yz400f came out and I wanted to get one so bad. Didn't know how good I had it!

[@azteqog6018]

Snitchy1989 my 06 YZ250F starts so easily man first kick when cold and when it hot pull the hotstart in and it starts just as easy

[@jakestech28]

Hot start levers are great.

[@Dommy_Doo]

my yz450f with a high comp piston starts first (sometimes half a kick) kick hot or cold. it all depends on tuning and maintenance

[@jayreal407]

Hot start my friend!!!

[@dannymiller7187]

I remember when this bike came out. I was confused with the 426cc was wondering why they didn’t do a 450.

[@juandiaz4116]

Because the yz400f was enough since at the time 550cc where still been allowed to race but yamaha uped the displacement to 426cc knowing others were aiming at the 400f so they did to buy time they simply went to a bigger bore 95mm vs 92mm for 400f since to get to 450 it needed to be stroked also so they waited till 03 when the ama lowered the limit to 450cc to make the new engine

[@redkasamuel]

btw i know its late but these bikes are very hard to start , ive owned one and theres a method to getting it started first kick. i believe it was with a certain combo of using the decompression lever and kick it over 2 3/4 times before the kick start gets it going everytime!

[@dillonbmx16]

to fix those dented 2 stroke pipes, plug one end of the header, fill it with water and stick a pressure washer in the other side with some rubber around the end and pull the trigger just give it a blip or two till the dent is mostly or completely gone. dont hold it too long or youll pop the pipe like a balloon but youll know when to stop well before hand

The front fender has that hole in it so you can get more mud in your face. It helps to make you feel like a more accomplished rider.

[@c3surfop]

"There's some green ninja turtle colored varnish" got me off the hinges over here bro!!

[@confusi0n358]

Your meant to find top dead center (TDC) using the decompression leaver - Hold the small black leaver in while you kick it a few times - Once you've found TDC then you hold in the clutch and give it a good kick. From what I saw you were just trying to kick it without first decompressing the engine. Pulling the cold start out helps too.

[@reganmorben9248]

INCORRECT> You want to find 10 degrees past TDC then kick it. He was using the decompression lever but I'd say he was only like 3 or 4 degrees past TDC. Also my 2002 426 likes about a dozen full click throttle blips, the choke out, 10 degrees past TDC, and then kick it. It starts 1st, 2nd, or 3rd kick EVERY time. ** Look up "Blue Wire Mod for 426"** I believe it disables the neutral safety sensor (totally unnecessary on this bike) which gives you another volt or 2 to the ignition, it really helps.

[@billpiper795]

Congrats on starting that blasted thing! I sold my 426 for that very reason! I’ll stick with 2 strokes or electric start from now on. 😁

[@Promod2001]

Yz426 is a great bike! I race one in the Virginia championship hare scramble series!

[@dontbethatguy1986]

Have this bike. Use the compression release a quarter through cycle. Then kick. Starts first kick every time.

[@rontomsethman4366]

always put gas in the piston,when it sat awhile, sure bet to get the gas flowing. i fix up bikes also, i found that a little painting oft he frame, makes it look new.and the paint usually cost a buck, good job though.

[@chico11432]

alright!!!!!! change the jets n clean the idle screw when u get it running like it run in neutral for a couple of minutes just a thought

[@TheTT124564]

The trick to starting those is to push the kick start till it hits the compression and then let the kick start up and pull the little leaver on your left ( should be above the clutch) then pull that and push the kick start like a half inch or a inch and then let the kick start come back up and let go of that leaver and then just kick it should star ever time when u do that

[@patricknavarro2013]

I have the exact same bike. Mine has the little black lever for the compression. I hold that down then easily kick it over 3 times then I let it go & kick it one more time really quick & it starts right up.

[@donalddaniels5848]

All that kickstarting and sore foot reminds me why I traded my yz450 for a drz400. Electric start and street legal plates on a dirt bike is awesome. Of course you need to throw the cv carb in the trash and put the keihin carb on it.

[@flavrdPnut]

Old ass video but I just got one of these and I’m running through it just like this reviving it. I’m having trouble with the throttle cable adjustment and was hoping you explained how you did it. Hope the thing will run when I’m done.

[@TheSeven2Heaven]

defianetly clean the air filter and your idle/stalling problems or any bogging or hanging of the idle is all in the carburetor!. The jet sizes and fuel screw and idle screw etc.. If you adjust those perfectly your bike will run 99 times better! for a couple dollars in jets and like 3 hours. Also here are a few things you should do to the bike (I'm telling you this because this is what you should do when you buy a used bike): Clean/ re-grease the linkage, bleed the front brakes, change out the radiator fluid, set the suspension to your weight and riding style (tutorials on youtube), change rear brake fluid, clean/lubricate the throttle and clutch cable. Then heres some things I noticed: Replace the rims, spokes, rotors, chain and sprockets, re-pack the silencer, new plastics/graphics, new grips. And by the way don't run water in your radiator!!! Use something like maxima racing coolant or something. Also, replace the fork seal. And then any rusty bolts whatsoever on the bike should be replaced with new ones. And finally get a new front and rear axle. That should do the trick! Then get riding and enjoy!

[@emptywindexbottle97]

These bikes must get so happy to see your house after the rough life it have had

[@yamahafan7330]

They're easy to start if you find the right spot before you kick it. You need to turn it until you feel the hardest spot, then kick.

[@gittyupalice96]

dunno if you've gotton the bike running or not.. but the trick I do, is hold the decompression lever and the throttle wide open, kick it over 5 times in a row, (this cleans out any old fuel or if it had too much fuel) then use the decomp lever to get it in place, and it will start 1st try.. at least for my bike, and mines been riden 10 times harder than that one I can tell you that much lol. just a little trick ive found.

[@I_Am_Michael]

good job. sounds like a nice, tight engine. I, also, notice no smoke out of the exhaust when it did start. clean the carb with pine sol.

[@jenniesgarage]

You're right on the engine. Even though the bike looked crummy, I don't think the motor had much run time.

[@willelliott8100]

Mid way through the engine rebuild on a 1997 kx100, planning on doing a full restoration since some knobhead painted the frame the wrong colour and snapped off many a bolt in it.

[@bogartscandalous2281]

I loved this video. you earned yourself a sub. keep it up

[@romper9064]

Hey useful peice of advice I own a 2001 yz426f and I had the same problem be4 as well... what I did with mine when it got fludded just turn your gas off and lean the bike over until the gas in the carb drains out... turn your gas back on then it should start within 2 to 3 kicks

[@jenniesgarage]

Interesting idea, thanks!

[@tpayne2110]

dont hold it throttle wide open, if its flooded lean it to the left side real hard u will see the fuel run out the carb. then lean it back up, tap the throttle nd then try to kick, works liek a charm

[@mtbridingog9083]

Also never go against compression on any bike especially 4 strokes they tend to kick back at you alot so use the hot start to help you out with starting it or compression releaser

[@JETZcorp]

Boy. I deal mostly with 70s bikes. It's kind of shocking to see what looks to me like a "brand new" bike to be in old, neglected, vintage condition. The march of time is truly relentless.

My buddy had a brand newone in 01 I think. It was fast with great suspension

Wow! 5 Valve. Just like my old 2000 Audi! 3 Intake, 2 exhaust. Makes for a fire breathing monster! (My Audi had twin turbos, though). Put a turbo on it! ;-)

My wife would kill me if I bought bikes like you are lol. She flipped when I bought a RM 250

Factory jetting was off in these; needle, pilot, main combo wasn’t even on the jetting chart on my 2000 426. Secondly, if they’ve been sitting a while, just clean the carb/jets, fresh fuel, then find a really long hill for a bump-start-a-thon!!! Lmfao. Once the jetting is right and the carb is clean these things start right up once you wake ‘em up
