Pipe should be here tomorrow. Im excited about the pipe but Im not looking forward to starting over tuning the carb again. I talked to KMS about a clutch, he said stick to the oem with redline springs. Hpr isnt returning phone calls lately so Im going to stay with the OEM I guess. Donal is running stock clutch with redline springs with about 80 to 85hp. Holds good with me on it so I will can the RW springs and try the Redline.
