Got a 2008 Wolverine 450. I love this bike but I need more power. Got to thinking that since a grizzly 660 is a single cylinder auto with shaft drive that it should fit with only a little modifying. The only problem is I'm not familiar enough with these engines to know if there is any major differences or easy access to one to measure it.
Appreciate any information or thoughts anyone has to share

 

i have never heard of it being done. altho i have had the same thought many times..... pass on any info you can...

there is a stroker 488 kit as well if you do not allready know about that....few people have posted they have it and love it.... just an option..

 

yhea the 488 kit is not a stroker just a very big bore kit, if you stroke it it will make it a 500.

The 660 will be heavier I am sure, you might be able to do it. First off would be making sure that the engine will fit the frame.

after that, i am sure you will be welding new mounts and will need to reinforce the frame(adding more weight.)

 

I've seen the stroker kits but I am a firm believer in the no replacement for displacement rule. Still trying to find a motor but I will post on my progress once I find one and get started. Might not catch my buddies Renegade but I bet I'll surprise him

 

also think about your suspention..The Wolverine shocks are...Well known to suck.With a heavier engine.It will add more stress to an already crappy suspention..By the time you mod everything you need to make everything work right..You might as well trade it in for a Renegade 800.. I wish I would have gotten one over this raptor..

 

To be honest I've no real complaints about the suspension on my bike. I've already accepted that I'll need some upgrades like front shocks, probably front axle shafts and maybe even the front diff. Pretty much everything I drive ends up this way. 90 chevy's had the motor "improved", trans done and solid axle swap underway. Just the way I am

 

I think you would be better off to sell the 450 and buy a 660 Grizzly, or just modify the 450 engine. If you swap engines and ever try to sell it, most people do not want to buy a heavily modified quad, especiallly a utility.

 

I think selling isn't a huge issue for me either. Modified bikes don't sell real well around here either. Way I see it all I'm trying to do is what Can-Am did and what Yamaha should have.

 

whats that build a non reliable over priced atv?

sorry i love the looks of the renagade but all the can ams i ride with are garbage ! i pull more of those things out of the bush than any other !

 

+1 for the no replacement for displacement.
