its breaking up probably at 10,000rpm & up.No gauges so I cant say for sure.No FI codes.It will rev to redline but just wont pull above 10,000rpm.changed plugs & my gas.Its not the clutch. WTF any suggestions?

The coils maybe? I dont ******* know.Works fine in lots but I took it on the street the other day and thats when I really noticed.

 

could be carbon build up from riding in the lots to much

 

you fix it yet?

 

test your regulator rectifier and stator, mine went out and had similar symptoms. the rpms would surge up but the bike wasnt pulling at all. good luck
