does any one have a big bore kit in their raptor 350's,if so where did you get yours and how much?

 

Lots of people have them in their warriors, FST seems to be a popular choice.

 

would it be better to spend the 650 bucks to make it a 446 or $185 to make it a 366?

 

Would it be possible to put and FST kit for a Wolverine or another 4stroke Yamaha 350 on my Bruin 350? Do any of these companies have web sites with their prices?
Thanks

 

fst or four stroke tech, they have a website but its sucks, check out powroll.com

 

Alba makes a 400 stroker

 

a 360 something kit just sounds like boring it out to the last overbore. No good. Makes you have to buy a new sleeve when you want to rebuild and an extra 16ccs isnt going to do squat. Dosent matter what company gives you the CCs as long as they do a good job. Power will come from how you feeds the CCs. Stuff like an aggressive cam, porting, bigger valves etc... is where youll get the power.

 

is reliability an issue? or maintenance? you should also look at those variables when choosing your big bore.

 

with the raptor reliabilty is an issue if you get a big bore kit, atv sport said the studs are too close to the cylinder wall or something like that. They said it would be better to get a stroker

 

how much more reliable will a stroker be though?
