Warrior 350 2001

[yamahadriver13]

Hey guys, My warrior was sitting for only a week or so and when i went to start it, it was smoking bad for about 5-10sec and stoped it wasnt smoking when i put it away so how could that be any ideas?

Mods are only a white brothers exhaust

What color was the smoke? It could be your air/fuel mix screw. Dose it still do it after it warms up?

smoke after sitting a while that goes away quickly is usually the valve guide seals leaking by, you won't see any smoke while running or warmed up, but a few drops get by when it sits for extended periods, then burns on start up, puff of smoke, when the oil is gone, the smoke is gone. It will run like this for a very long time, just looks bad when you first start it. Don't worry about it unless the smoke stays for a long time, that could point to other problems. Just run it for now, you could fix it, but it would involve pulling the head to do it, unless you know a way to pull the springs without removing the head.

i had the same problem with my 2003 warrior. some oil had dripped on the exhaust pipe and burnt off

[95wolv]

That's a good point, dupont, he should definately look at that as well, but I would think it would take more than 5-10 sec. to burn oil off a pipe, plus the smoke would come from the front, not out the muffler.

[dupont]

it would come from the front but on mine it only smoked for 10 seconds

maybe it was like mine of corse it sat a lot longer( stupid rats nest)

Does anyone know if a yzf450 bumper will fit on a 2002 warrior?

Does anyone know if it is possible to put turbo on a 2002 yamaha warrior?
