Jiggins2895 Posted April 19, 2012 Share Posted April 19, 2012 Hi, I have a yamaha aerox YQ50, when i bought it, it has a standard exhaust on it, a few weeks later the exhaust blew and i had it replaced for a Leo Vince TT. Since then the bike has had a problem, when I slow down and get to around 5-10mph and accelerate again, the bike will bog down for about 20 seconds until it shoots off again, I have had the bike in the garage and the following had been checked: > Clutch and variation has been stripped, cleaned and checked > New rollers as the ones that came with my Leo Vince TT where not compatible with my bike > Throttle and Carb had been tuned and cleaned > The spark plug has been changed The mechanic is running out of ideas of what it could be, just wondering if anyone has any ideas/ experiences of this? Its a lovely bike and wouldn't like to get rid of it. Many thanks Link to comment Share on other sites More sharing options...

Jiggins2895 Posted April 19, 2012 Author Share Posted April 19, 2012 OKay just taken it to workshop, and the mechanic is a bike specialist, i don't know to much about bikes, he has cleaned them, the rollers where the wrong weight, they have been changed now. He did suggest changing the jet size, may have to talk to him about that! Link to comment Share on other sites More sharing options...
