Beta 250 rev 3 rough running?

Featured Replies

Hi all,

I have a beta rev 3 and it seems to be running a little rough, it starts fine but on idle the revs seem to be slightly up and down. It seems a little worse when riding, especially in second gear on mid revs it gets very jerky. If anyone has come across this problem or has any ideas on a possible fix i would be very gratefull.

Thanks
