I have a 1125r. I think it surges more than it should. I have fmf pipe and eb ecm. Up to about 5000 rpms it surges like crazy. I replace the plugs. I am very mechanical and can do about anything. First I just want it compared to other 1125's and maybe ideas of what to do. i do not get on here to much if you think you can help let me know. I will compensate you somehow. e mail is karate4fun@charter.net
