I was wondering if this over sized cylinder stuff was all a bunch of sh*t. I have heard many things but have never seen any thing very believable.

 

I have seen a few 600+cc Banshee's with cylinders from jetskis or snowmobiles. They were all drag Banshee's with lightened frames and hugely extended swingarms and of course drag pipes. They are so loud I wouldn't want to ride one. Drags are fun for maybe half an hour then they get really old for me.

 

Yes, I've seen Kawi 550 and 650 jet-ski cylinders and heads used on Banshees. I know it requires mods to your cases and might also require some crank mods.

Kawi 550 and 650 cyinders should not be hard to find, especially 550's. Those are the old stand-up motors which go really cheap these days.

 

WHY??
That's all I want to know!
