I do have one question though. How will I know when I have the right mixture? At least till I pass the emissions test.
Thanks again!
2 1/2 turns out is a good starting point.You need to adjust with bike warmed up idling.Turn out slowly (rich) till the idle starts to roll,than back in (lean) till idle starts to stumble.About half way between both extremes,to were the bike idles smoothest.You may want to stay on the lean side till you pass emissions than adjust for smoothest idle.
