thanks, its all stock as far as I know, other than the exhaust and aftermarket air filter, I watch the videos a guy posted on YouTube, it had the whole disassembly and reassembly of the engine, didn't look so bad to do as long as you have the parts lol, but I dont know much about banshees just always wanted 1, and know I have 1, I have a guy that's gonna rebuild it for me and he was saying I might as well bore it over or I will continue to have this problem
