My 84 RM500 is running okay with all the jets now replaced with standard RM500 jets, but its seems to idle at fairly high revs, especially after a ride. I like a two stroke to barely idle, not rev like the throttle is partly turned or the choke is on. There seems to be enough free play in the throttle cable, so that shouldn't be the trouble. Can't find any air leaks. There is no idle screw on a Mikuni flat carb, so I'm not sure what to try next. I can't actually reach the air screw; it is hidden behind the airbox, but I didn't think that controlled idle speed anyway. Maybe I'm missing something obvious; any other ideas I should try?
thanks,
Jady
