I found a cracked hose on the air solenoid way down where hose goes into the carbs. I replaced all the hoses with new. Haven't gone out riding, but suspect this is why both cylinders were running lean. Hoping it goes rich...then I will have to start working down to find optimum mains.

I am seriously thinking about abandoning the entire air solenoid system. I'm sure they serve some useful emissions purpose and make the bike more round town friendly. Suspect others will say they contribute to the bikes legendary performance.

Any commentary on there usefulness for a track bike.
