Alright there, got an X8R with a giannelli reverse exhaust, recently fitted it and my bike now gets to about 50 but at that speed it suddenly dips and goes slightly slower e.g 47-48 and it's like a sudden stop. I know my CDI is restricted to 9.500 revs could it be that?? Cheers BTW my setup is Giannelli Reverse 17.5mm carb Multivar
