Well, I don't want to add insult to injury, buuuuuutttttt. I think MFIC is right not every motor is the same and you need to get a starting point and go from there. It is time consuming and a real pain in the ass, but once you get it dialed in, your in like Flint...... I must have taken my carbs apart a dozen times in the past three days ( tryin' to get ready for sand mountain tomorrow, see ya there bansheeseat$$). But Jeff started me out at 172's, and a 55, in the middle clip, 1 1/2 turns out. Once I got the carbs synced I went to work on the mains and pilots, and my best results were with a 168 ( a tad rich so maybe a 165) and a 55 pilot with three turns out on the air screw (which would put me at a 52 pilot). By the way I am at 950' 70* in Northern Cali. I have a 421 cub (thanks Jeff), 35 PWK's, T-5's (I know, don't Start).
Anyway, just get a starting point and then go from there, but you need to feel what the bike is doing and that was what I was doing wrong. Once I started doing that, I had a direction to go............
Good luck man :biggrin:
