Thanks for the responses,that does sound too cheap and I'd hate to void my warranty too. My cdi is derestricted and I did change the variator,so if I get a freeflow air filter,doI need to upjet the carb and get an exhaust also? can I do just 1 of those things at a time or do I need to do all 3? I'm looking to do these things myself and I dont want to get in too deep cause I would have no idea how to adjust a carb or anything like that.I'm looking to do just about 40 mph so I can safely travel on roads posted 35 mph. Thanks again Dale
