Yoshimura Full System

[FUZZY_imp]

I have a friend that was the lead technician with Honda Racing for Miguel DuHamel (Yvon's son) a number of years ago, who now runs an independent shop here in Portland. I recently stopped by his shop while out on the CB1100 to pick up some parts for my Hawk GT. He said that the bike was running lean based on the exhaust note upon deceleration — very common story. He suggested a Power Commander unit (which was not available at the time). I have no idea what's involved with installing one of those.

Great report! From observing inside of stock header & running Yosh, I can definately tell you it's running lean. He is also correct about exhaust on decel. No hint of any additional fuel delivery. As far as install its simple plug n play. Mounts under seat with hooknloop. Then just take to dyno.
