I've seen a few people that have their wolvies overbored with a FST 488 kit. I have searched (exhaustively) online for the kit, with no avail. Can someone give me a URL to a store that may carry it.

 

These guys have the 366 ,435 and 446 big bore kits. http://www.fourstroketech.net/

Look under "Engine Products"

 

I looked there, didn't see anything that would fit my '07 Wolverine. Or a similarly sized Grizzly.

 

Opps ,I thought you had the 350 Wolverine.

you were right the first time....phone mickey dunlop at fourstroke tech

he has the kit...it is just not listed.....that is who i got mine from... and it is great...

 

Chevy 68 has it right that's where mine came from

 

Thanks for the info. Has anyone that has installed the big bore kit had any problems with the rest of the machine keeping up with the motor (i.e. clutch, belt, etc.)?

 

How much did it run each of u?

 

The 488 was about 7-800 for the kit and camshaft. Then you have to have the sleeve pressed in and bored to piston size, then the cases have to be machined to fit the new sleeve.

I ran into about 500 labor when i dropped mine off to have that work done and I also had the head ported and polished.

He doesnt have the new stuff listed on the website but that is where I got mine at.

Ive never had any problem with anything else on mine. I already had the epi clutch kit in and some other stuff and havent had a problem with the belt at all yet.
