So yesterday I bought a 2003 Banshee on OfferUp for a steal. The guy bought it from his brother in law who built it and from the looks of it put several thousand into it. After using it only a handful of times, he got too busy and it sat in his garage for 2-3 years. It's got a Coolhead, full Toomey T5 exhaust, extended swingarm, custom billet clutch and stator covers, hot rods, ported cylinders, extended radiator, adjustable billet stator plate, and a few other things I think. It's been bored somewhere in the neighborhood of 2.5mm over stock as near as I can tell, I haven't been able to measure it with calipers or a bore gauge yet. So the sad part is that from the looks of it last time it was taken apart/rebuilt, it got slapped back together in a hurry. There's gasket maker on pretty much every seam where there should have been a proper gasket (heads, clutch cover, between the cases, and all over the boots on the reed cages). I have the engine completely disassembled and cases split as of right now. When taking out the clutch, I noticed there is a pretty good amount of play between the clutch basket and the gear on it, which from what I've read indicates bad cushions. I'm putting together a list of everything I need to buy to get it running, but I want to save as much as I can where possible. Right now my question is how bad is it to run on bad clutch cushions? Will it lead to further damage down the road or affect performance?
