I have a 2007 keeway f-act 50. it has developed a proble, its starts fine but when i pull the accelorator the bike goes up to around 7000 rpm and the engine starts to cut out. i have checked the HT lead and it was ful with grit and oil as the bike has a bit of an oil leak from the 2 stroke tank. i cleaned out the HT lead much as i can but the bike still cuts out a 7000 rpm. can anybody help quickly as posible. if you know anything please e-mail me on [email protected] thanks.
