I am looking for a big bore 400 kit for a yamaha warrior and I can't find one anywhere. I looked all over the internet and the only bore kits they have are for two strokes. Any help would be appriciated. Thanks

 

Check with Curtis Sparks Racing. He was building a 440 kit a year or so ago & maybe still is.

 

Check out ALBA also.
They sell stroke kits and or sleeve kits for the warrior there pretty pricey though. For 2500 bucks I'd sell the warrior and buy a raptor

 

I can't remember if it is ct or Alba but one of them makes a 400 stroker kit for trhe Warrior. and I think it costs like $800-$900. they say that it will make your warrior faster than a 400EX. Sounds like a good investiment.
