I'm intirested to see if anyone would make an offer on one of these motors. Both are on bikes and run great. The GT-5 tops at around 32, the Ratwill get closer to 40. Which either one i decide to sell will come with a SBP black expansion chamber. The GT-5 ive done some work to. It has a Dax RT carb(that kicks ***) silencing kit, upgraded plug wire and cap and custom heat aluminum heat guards that keep you from grilling your leg. Both have been lovingly broke in and start, idle and run perfect.
