I got a 98 zr600 efi. When taking off, it seems like there's a dead dead spot in the throttle. it only happens between 10 and 30 mph. Not sure were to start on this issue. There is a small crack in the exhaust pipe, and not sure if a lack of back pressure could cause this or not. other then this it runs perfect. Starts right up and rips after 30 mph. Any advice would be appreciated.
