SOURCE: How do I adjust the valves on my 2003 Yamaha Warrior YFM 350X?

first you need to remove everything that covers your valve covers(gas tank etc.) remove the intake valve cover,and the rotor nut and timing plug.set the engine a t.d.c.(top dead center)fit a socket onto the rotor nut and turn it counterclockwise until the"I" mark appears align it with the index mark in the timing hole.use a flat feeler gauge between the top of the valve and the adjuster.loosen the locknut and turn the adjuster just until you feel resistance on the feeler guage.hold the adjuster and tighten the lock nut down.i can not tell you the min.clearance spec to your quad since i have a 660 raptor.try using the smallest clearance number.

SOURCE: will 1989 yamaha 350 warrior cdi box match up with

HELLO; No, the 87- 89 are only for those years, yamaha changed the wireing looms three or four times I can't remmember, youll have to get one for your year of quad for it to work right. Check on line for a used one or new at better than dealer price. GOOD LUCK.....GREASY.

SOURCE: My 2001 Yamaha warrior yfm 350 makes a loud ticking noise

valve train .Take off cam sprocket cover and check timing chain for play.Do to tight springs and steep lift cam you will get backlash(ticking) from a lose chain regardless of tappet adjustment.If it is back firing more than normal you may want to overhaul the head and replace rings.as well as timing chain.

Will a yamaha 350 warrior cdi work on a yamaha 350 motot 4 they look exatly the same


I would call the dealer and have them check the part numbers. If the part numbers match then yes you can. Alot of the time the only difference is the connector. Yamaha has alot of interchangeable parts but the safest way is to verify the part numbers. If you just " try it " and they don't match you just may have fried the cdi box and you'll be trying to troubleshoot a bad part that you think is bad.

My kolpin fourwheeler will idle, but stalls when i give it gas


hello, make sure your spark plug is getting a good blue flame, if not you may need cdi, i replaced one on my atv, would idle all day would not rev up, cdi boxes is the brain of your atv, motorcycles tells it what to do as far as firing, timing advance, hotter fire to plug etc..my atv is a 2000 350 warrior, their known to not have very reliable cdi,lots of problems with warrior cdis....

Yamaha warrior atv [yfm 350] bogging problem


Try checking the switch for your parking brake. It is the top wire in the clutch handle boot. This wire connects to your CDI box, and restricts the RPM's while the parking brake is engauged. To find out for sure, trace the wire down to the plug under the headlight assembly and disconnect it. Now try starting you machine and give it some throttle!
