| there is no perfect tune for a range or carbies. You have to tune it by trial and error. People can give you a starting point, but every engine and bike is different, aswell as the rider. There are too many variables to compensate for, so you have to tune your carby to your variable. Just get a screw driver and take the bike out, get it warm then play around with the mixture till you find something that works. good luck with it |
