CharlieB Posted October 2, 2014 Share Posted October 2, 2014 I've got a Yamaha Jog RR air cooled and I've put an sports air filter on the standard carb I have adjusted the mixture and now have got the throttle to respond but I cannot go full throttle as it feels like there is no power can anybody shed some light on my porblem. Thanks Link to comment Share on other sites More sharing options...

Thanks It's probably lean at wide throttle openings, could result in a holed piston. you should fit a bigger main jet and did you oil the filter slightly ?

Moderator Airhead Posted October 2, 2014 Moderator Share Posted October 2, 2014 so just try a quick on/off with the choke how does that affect it with regards to the full throttle problem? Link to comment Share on other sites More sharing options...
