Great little write up on jetting and carb tips.

Just wanted to add what Jets the "Mikuni" and "Molkt" Carbs that come on the bikes use.
Pilots are Mikuni Smalls Part # M28/1001-(jet size)
Mains are Keihin Rounds

Pitster Pro has them in stock.

MANY GREAT TIPS ON THE WEB AND MANY PEOPLE WILLING TO HELP!
