I am thinking of getting a big bore kit for my 2001 wolverine. What is the biggest big bore kit I can get on it. I heard that FST has a 435 kit.

04 Honda Rubicon
03 Kawasaki Prairie 360 4x4
01 Yamaha Wolverine fmf exuast. K&N air filter, Warn 1500, moose fender extensions, brute running boards, maier hand guards

 

FST goes as big as a 446. Not sure what sizes smaller than that are offered.

I'm in the middle of tearing mine down to send in for the 446 treatment.

There are several other FST Gurues that frequent this forum. I'm sure they will have more info for ya.

 

So what do you need to do to get a 446 kit on it?

I'm not sure if you can send the whole motor into FST or not. I am going to tear mine down and send in the following:

Head, cam, cylinder, crank, both case halves.

The way I understand it so far, Mickey will take your cam and crank in exchange for the stroked crank and performance cam. He will machine your head, cylinder, and cases (assuming you want him to do the machine work).

I am by no means the FST 446 authority. I've only had one conversation with Mickey so far. I didn't want to pinpoint all the details until I had the motor apart and ready to send to him.

Tearing the motor down is turning out to be quite a challenge...tool wise. Everything they have you doing, following the Yamaha manual, takes a special tool. I've been talking with a couple of guys on here and have picked up some tips for disassembly. I'll have a lot more details on what tools I ended up using once I get this thing apart.

 

Is there any other big bore kits that i dont have to send my engine in and i can do it my self?

 

All those kits require machine work, you need to bbore the head, etc. So unless you have a machine shop, i'd say no.

 

366cc not a real big boar, u can have it bored out at a local shop, not sure how good it is, mine is not together yet.

 

I dont have a problem on putting like big work into my atv my dad owns a gastation with a body shop and everything and some of the mechanics has a atv and does alot so he said he would be more then happy to put a big bore kit in.

 

BigBaller - What kind of power are you wanting? Also what do you want your Wolverine to achieve? Understanding that you are only 13 years old, I am sure you will need some major help getting it out and rebuilt. It's heavy so be careful, I moved mine around the building a few times when I was working on it and it was pretty hefty. Tell me what you want it to do, and I can tell you what to do to it from there.

 

BigBaller can you tell me where you got your Brute Floor boards and how much they cost. Do you have a close up picture. I need something to keep the mud down. Thanks.
