I love this bike. I have to get used to it because I went from a 2018 SSR 125 4 Stroke to this beast and the powerband is crazy and a more responsive throttle. If anyone has any good tips or just wants to comment about it feel free. I love good info and tips that will help the bike and myself. I basically stole this bike at a price of 1200 running and ready to ride. Just some minor things like needs new brake pads upfront and new levers. I just replaced the radiator fluid. Also gonna bleed the brake system and put some new fluid. -
02 WR426 Ticking when moved around in neutral w engine off
Alwaats posted a topic in WR400F/426F/450F
Hey Guys, i've noticed a ticking noise when i'm moving my bike around. It's quite loud and i thought it was just the chain on front sprocket but on closer inspection the sound does not match the rotation of sprocket tooth/chain so it really must be coming from the sprocket shaft inside the gearbox. Having never had this box apart and facing a mammoth task if i do so, would anyone have some advice or history with this? is it normal? wear and tear and to be ignored? or is it undercutting/mis-alignment of gears and about to grenade on me? -

Great bike monster power delivery after you install stage 1HotCams setup both camshafts exhaust and intake starts first are second kick rode new 2015 450 and believe they both have same amount of horsepower but power delivery is a little different on the both the only downfall is the yz426F is a bit on the heavy side and bike sets way to high unless you're 6ft are taller but besides some down falls its a pretty indestructible bike for being a 2002 model perfect for motocross are a good in the woods trial bike you either love the bike are hate the bike for me its a great all around motocross machine but really wish it set lower to the ground that's the only downfall that I hate the most of the Yz426F so im finished talking about the 2002 Yamaha yz426F im out peace sincerely Andrew Schmeerbauch. 6/18/2015<br /><br /> -

Clutch updated, no more grabbing. Devol rad guard, lever guards, Dr D pipe, awesome bike -
i did This Recently to my YZ426F. i used a 14.4V Drill battery and 2 computer fans. The key is to getting a clean install so you do not make your bike look like trash and you do not get stuck on wires. the biggest question that i had when looking how to make these fans was how long they would last. Mine last 4-5 Hours. In all of the trails I've done i haven't ever run out of Juice for them. When i am going fast i can flip a switch and shut them down, but i have never had too.

My buddy thinks his 97 yz 250 2 stroke would beat the 01 yz426f I am getting. As far as I know the 426 is stock with just an aftermarket exhaust. The 250 has v force 3, I think 51 rear sprocket not sure of front, has pro circuit exhaust to. I weigh around 180 and he weighs around 150. Who would win on takeoff and top end???

pulls hard, not for traffic jams, it overheats -
About a month ago, I dropped an exhaust valve. I then bought a WR426 head, brand new Wiseco Piston, Intake and Exhaust HotCams, and a new spark plug. Just to clear it up, it is a YZ426 bottom end on a WR426 head and WR426 valves. Valves were professionally shimmed. The only thing from the WR426 is the head and valves, rest is either new or from the original YZ426. The engine is now built, torqued to spec, and kicks over easily. Problem is, it will not start. I have spark, fuel, and air. Carb was not touched, other than taken off and put back on. It will backfire every so often, and it is extremely loud, never heard my bike do this before, but it shows I have combustion. There's some theory's I have, such as the pilot jet in the carb, since it sat for a month it could of got clogged. If you have any suggestions, please let me know. Thank you guys, I'll be in touch!

Sold! This was a strong running, very fast bike. However it was very difficult to start. This bike and the 2002 model were notorious for that. -

It's fun when it wants to run. Starts first kick when cold and picks the front end up in every gear. -

So far I like the bike, it is plated and street legal. It's not running quite right and even still has loads of power! Can't wait to get the carb tuned up -

So I am converted my 426 to a dual sport ( well, am in the process) However I need some help with the stator wiring. I picked up the WR426 stator just to charge a 12v battery I am putting in the air box. I bought the needed regulator/rectifier (trail tech) to convert the ac (stator) to the dc (battery) to charge it. The 12v battery will be lighting a 35w 12v polisport headlight, tusk tail light and turn signals and a horn. I am just curious as to if I need to mod the stator to work with the yz wiring or of the regulator/rectifier does that. Plus I have no clue how to wire the headlight. It has 3 prongs for the main light (the wiring diagram said ground, medium, maximum) then had a tiny lithe bulb to the side that says 4w and has two little wires that are a 2 pin connector, and like i said i have the tusk wiring kit which has the main switch for the head light but only has 3 wires for a main headlight a low beam and then a high beam, other than this, the bike is ready to go and I am dying to get it out on the road.
