I just installled a JD jet kit in my bike. I just installed what the instructions said for my elevation which is right around 3500'. it was about 68F. the stock jetting was 40 pilot 180 main and I cant remeber what the needle was set at. Im now running a 42 pilot a 172 main and the red needle on the 5th from the top clip. It seems to start better. heres a pic of the plug after a quick rip up and down the alley. the reason a jetted it in the first place was i thought it may get rid of the hanging high idle but it hasnt. Ive tried pulling out the choke while its stuck in the high idle and all that does it speed it up more.
