Hey everyone,
I just bought a 2001 Bullet with the classic (short) muffle, stock carb. with stock jetting (#25 pilot, #110 main, jet needle clipped at 2nd position from bottom, and Power Arc ignition). It shows evidence of lean condition at idle (erratic, hunts) but otherwise runs fairly well. I'm retrofitting a K&N filter into the stock airbox but otherwise am not making any other changes to the engine (for now). I envision starting off with a #30 pilot, #120 main, and needle in middle position. Altitude here isn't very significant (around 600 ft.) Some gas in the area is reformulated with alcohol, which can tend to make a carbureted engine run leaner, but I try to run non-reformulated gas whenever possible. Any thoughts or suggestions about jetting and setup?
Thanks,
Al

There are several good threads on jetting. You may wish to do a search for them. The 30 pilot jet may be too rich for you - it was for me. I am currently with a 27.5 pilot, needle full up and a 120 main. Right now that works very well.
Think about getting the jetting kit from CMW. It's a very good kit with all the jets you are likely to need for any future mods you may do.

I think I've posted this link before but it's a good place to start when messing with the carb. http://www.motorcycleblog.org/bulletblog/afterexhaust.html

Thanks for the advice, guys. I considered buying CMW's jetting kit but I already have all the main jets I'll likely need. I do have a couple of pilot jets and the "Mikuni Pocket Tuner" on order.
Leonard: I've read that article. It's a good one! I'll be referring to it, no doubt!
