thanks there's a 62 main jet in the carb as standard and yes oiled the filter and was working fine until you tried full throttle.

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
