Totally agree!!! It's one of those you'll just know as you become ONE with your sled.driftpounder said:No you won't have to rejet as much if you run it rich, but your going to know that it's running rich.
I found with my CPI twins, I didn't like it running rich, sled would load up and ran like $#!%, less power then if I had left it stock. It was best running as close to what was supposed to be in there for your temperature and elivation. I found after a few rides I could tell exactly how it was running before I would pull the plugs just by how well it was preforming, only had it on the lean side once or twice before I had it figured out exatly when the best time to change the jets were.
