I wondered if any other engine had the sane 54mm stroke, the same rod to rod distance...but with bigger bore (BTW, what's the biggest bore that will fit?).

Thanks

 

With modifications, nearly any two-stroke twin of a relatively similar displacement will fit... I've seen Kawasaki 650cc jet ski jugs on Banshees, and I recently bought a Banshee tranny with Arctic Cat snowmobile cylinders and crank welded-on; the result is a high displacement "stock" motor.

But, if you're looking for a bolt-on increase in displacement which I think you are, you won't find cylinders from another engine that match up exactly to the banshee cases. Try the Superior Sleeve mono-block cylinders... 470cc with much less modifications.

 

Zorro-
Seeing a Banshee with big bore cylinders and a trailer hitch(?) would certainly be a first. Anyways, unless you've got stiff drag race comp up there, you can do alot with the stock jugs.

 

Better get it bored Zorro my friend, after next April you will need it to follow my ported, head modded and newly carbed Scram! LOL
