just got an 03 YZ450F that was sitting around for a while. when i got it it would start but had a hard time staying running and couldnt idle for a second. i did the best i could to clean out the carb. there was no major gunk in any of the jets or on the needle. it seems to be running fine now except that it will not idle still. it was originally rode around 1300 feet and now im around 162 feet. is there anything i should adjust as far as the c-clip or maybe re-jet? any suggestions at all? Oh, and is it worth the time and money to have it hooked up to a gas analyzer to get it tuned? thanks and i appreciate any words of advise.
