January 22, 200917 yr Hiya chaps, just purchased an 01 250 to ease me back into trials after 20 years away !! The bike seems to be in good order and doesn't look like its done a lot but when riding it it doesn't seem to have a very high rev limit and is possibly running rich. I've had the carb in bits, cleaned and set the float level, and fit a new needle and air filter. 1 I could just do with knowing which grove the clip should be in on the needle 2 what the setting is for the air screw, and is it in for rich and out for lean ? cheers for now Stu Edited January 22, 200917 yr by SJM
January 23, 200917 yr Gday mixture screw is roughly one and a half turns out. Fine tune for your bike. In for rich, out for leaner. This will only effect idle and to a very small degree starting and just off idle conditions. HTH, Cheers, Stork
