I just bought myself my first Fz1 (2003). It has a yoshi slipon, RS-1 which is pretty quiet I thought. However my main issue is the bike has some lean surge and light throttle. The previous owner said he "thinks" it was rejetted. After inspection of the carbs I noticed the idle mixture screw plugs are still there undrilled. What do you guys think the odds are that the carbs have actually been rejetted?
