My R50X runs great when on the stand revs up to 8000 rpm no problem, however when i run the bike down the road past 6000rpm the scooter sort of dies drops revs as if it is blocked / clogged, when i rev it again it will go back up to 6000 rpm and if i hold it will keep going, however if i attempt to go past this rpm it drops in power
Any ideas?
Help appreciated
Regards
Shaun
