does anyone know anything about WSM piston kits? I found a 0.20 over kit for a good price and was wondering has anyone had any luck or unluck with it cant wait to get my trailblazer 250 back together

 

no i have never heard of them and that should worry you...get a wiseco and then you dont have to worry about it...thats what i would do.. i have heard to many horror stories on here to buy off brand stuff

 

i have heard of them... they are sold through parts unlimited.
but you cant go wrong with wiseco.

 

I have used WSM pistons in past quads and never had a problem. No you cant go wrong with wiseco but wsm is good also. They even have coated pistons. You can find these on ebay very cheap but if you have the extra 20 bucks then go with the best. Anything is better than stock at this point.

 

i heard the coated piston in the 400 wear out easily,
and have problems with them.
go wiseco,coated piston is for nikasil line cylinder only.
