when i start my bike the bike idles really low then jumps up after about 6-7 seconds if i kill it and start it right away it will stay at the same idle i have my adjuster set at but if i let it sit for about 3-4 seconds it will go really low then take 6-7 seconds to jump up bike runs like **** if you touch the gas before it jumps up always have to wait...people are saying my stock idle air/fuel adjuster i'm not sure where it needs to be set at...any other ideas?
