...White plugs means too lean...What do you mean, seems rich? How can you tell?...What about your float height. Could it be set too high?... Is your choke circuit partially on?...Just seems really weird to me!



Plugs...yes they looked lean overall, hence the switch from 152's to 155's. I need to take another look at the plugs & reassess.

Float heights...on or about 17 mm, right on spec.

Rich at idle...it's not far off, but there is an occasional "bang" off-throttle on decel (not decel popping), & the bike will run happily off-choke sooner than what I would otherwise expect, & it will soot the plugs if allowed to idle long enough. No baseline RPM dip on rev on return to idle, though. No A/F #'s, so I cant specifically quantify it yet. The easy answer is "go to the dyno & find out", however I'm not ready for that yet. All that said, it's not far off, though.

Choke...is off.

Weird...yes!
