I have a '97 350 Wolverine.It has started to smoke and burn oil and I am wanting to overbore it. I have seen in magazines people talk about a 500cc kit,but I have yet to locate one. I really dont want to stroke it,but I would like to take it to a 400cc if possible.I play in the mud ALOT,and it has been fine as it is as far as tourqe and power,but I figure if I have to build the top end,I may as well get a little more out of it.As for now,I am still running 23"(Good Year Terra) tires on it,but plan to go up to 27" 589's in the near future.I already have a plan for the suspension to gain enough fender clearance,and it will also increase my wheelbase by 3".I plan to change to a HotCams stage 1 camshaft as well. I am running a K&N filtercharger kit,and a custom made exhaust at present,but will be changing this out to a Cobra Jet Aluminum Warrior system when I rebuild it. Can anyone give me info on where to locate a big bore kit for it?
Oh,and is there any place to get aftermarket CV joints out there? I have a clicking outboard joint. I refuse to pay Yamaha prices for a new one...

 

Alba has the 400cc stroker kit, check them out, OR if you want to go bigger, Powroll has a 430cc kit and FST makes a 446cc kit, its just how crazy you want to go and how much you want to spend.

 

where can i find the FST site? I googled it alot and cant find anything.. do they even have a site?

 

they don't have a site anymore, you can find a ad usualy in dirtwheels and you have to call them.

 

My 446 pulls pretty hard. I like it really well and was impressed with the power output compared to stock.

Four Stroke Tech - (814) 842-6159

 

Speed demon, Whats your top speed? Do you got pics of ur wolvy?

 

I was looking at the Alba site, and they only list the Worrier. Are all the engine parts 100% interchangeable??

And are all the Wiseco piston interchangeable, cause i can't find the Wolverine in the list of bikes.

Thanks

 

Yes, Warrior and Wolverine parts are interchangeable, just not from the crankshaft down.

Top speed is something like 65-67mph. My buddies Raptor is geared down with an 11 tooth sprocket and he has an hmf slip on and it will hit almost 71mph and he doesnt pull away from me that far. I was drag racing my buddies car...lol out on a country road where it didnt matter, and it pulled away from him pretty good and I was running 64 when I ran out of straight away and my jetting was messing up, it couldn't wind it tight. Sorry I dont have any pics yet, but Im trying to get some soon. I have to replace my ball joints right now.

 

Im hoping(Wishing) to get a 430 kit from Powroll or w.e Will that make a big diff in acceleration n top speed?

 

The 430 Powroll kit is for Warriors only, they don't do strokers for Wolverines
