hello again everyone, took the bike(nc30 with nc35 engine) out for a blast today as i should imagine most of us did cracking weather. altho today when the bike hits about 9000rpm the bike starts struggling and backfiring. it is running fine in low rpm well sort of died a couple times on idle but fired back up and rode away. and ideas chaps?

Also have you changed the vacume tube recently? older ones can collaps when they get hot, and it has been nice and warm the last few days
