I'm planning on getting a new carb since I'm still running the stock 26mm... I'm thinking of going with a 32 or maybe the 35mm keihin. Is it possible to bore out a 32mm to around - 34/35mm? And once I buy this new carb what else do I need to fit it on my blasty... I know I need a new intake boot for the reed cage (depending on what size I get) but do I also need to get a new boot for the air filter? (I have the stock airbox)
