throw that bike away upgrade to a 450f it will change you life


That's the best you can do with your first post? :excuseme: Boo! I've met some 426 riders that I'm sure could spank most.

OP, Welcome! The 426 is a bit outdated, and kinda heavy in comparison to newer technology...but that said, is still years ahead of what I rode as a kid. How big are you? What kinda riding do you do?

I had one of those bikes, great bike. IMO, before you throw money into upgrades, go through the machine and be sure it's sound. The things I'd check would be:


1) have fork and shock serviced at a respected suspension shop
2) inspect bearings, particularly linkage, and wheel bearings
3) inspect breaks, bleed fluid
4) inspect drive train, I'd get a new chain\sproket kit to establish a baseline
5) dose it start easy? if not valves and piston may be in the near future


The 2001 YZ426 is a very capable bike you probably don't need to upgrade much.

Disregard the "ONE POST WONDER" above.... the 426 is a great bike!!!

I think its more important to get your jetting spot on than any pipe, but the fmf q2 with a powerbomb header gave my 426 a whole different feel. It will give you a lot more over-rev and mid-top end.

I HIGHLY recommend the JD jet kit.... single best mod i ever did to my 426.

My personal opinion on upgrades, once the machine is proven sound as you stated is:


1) protect the bike, skid plates, rad braces etc.
2) fresh tires which are appropriate for you terrain
3) keep a few dollars handy for maintaince, air filters, oil and such
4) probably should be first, but do you have all your protective gear? after all you can't enjoy your new bike when your laid up hurt


Have fun dude! From what I've seen, often newer riders get worked up trying to set up their bikes before they take care of the necessities.

Good idea on the chest pro. maybe some hand guards also! Try to ignore the static.

+1. You dont need the latest model bike to have fun. If you were racing newer is better but to go play ride for fun it does not matter. More important than modifications is having all the OEM parts in good working order like listed above. Then make the bike fit your body with bars, grips, seat to feel comfortable both sitting and standing. Just having fresh suspension fluids and seals and clean, lubed suspension linkgage makes a big difference. Fresh tires, chain and sprockets and a fresh muffler packing is more important for good power then aftermarket pipes. Most riders are not good enough use all the power all the time that these bikes make stock.

So, because you had ONE that you had trouble with, they're all bad? Interesting.

I think if you ran a poll of everyone who owns, has owned, or knows of a 426 well enough to speak to its reliability, you would find yourself in an extremely small minority. There are few pieces of machinery ever made that are more reliable than a YZ426.

Their one true "weakness" seems to be that if the rider has the habit of not shifting crisply, they will wear the locking lugs on the sides of the gears to the point that they begin skipping out/into gear under a load. Other than that, they are nearly indestructible.

Sorry, you're going to be going against the grain on that one.

I had an xr600r that was (prob still is) bullet proof. With that said the 426 is every bit as reliable as my old xr. Your experience doesnt mean they are a money pit. You prob didnt take care of it anyway......

Yeah you're totally in the minority here! My 426 has never had any problems and still has the stock piston and never needed a valve adjustment. It probably has 150+ hours on it just guessing, maybe more. Nothing has ever worn out except tires obviously, I just replace things for performance. If someone made a poll asking about 426 reliability I bet there would be less than a handful that agree with you!

I have a 2000 426 and IMO it is bullet proof. I replaced the piston finally and then put an auto decomp. cam in it. I have never had any problems with my bike. Just keep up on the maintenance and I think it will run forever.
