Is there a way to determine if a bbk is currently in the bike (cam/carb/..)? I bought it used.

Measure the piston... you might have mentioned you have a HUGE jet in the carb 10 posts back.. .?! Replace it with #110 or #112

Nope.. measure the piston diameter anything bigger than 57mm it is a BBK...could be 62mm or even 63mm. Can't really tell from the outside...
Stock jets run from about #106 to #110.. depends on the manufacturer, air box design, filter design, exhaust system design...
But anyone that put on a BBK ...when they sold a scooter would sure as hell be bragging about it...

Ok, I installed a New Coil yesterday and Runs Awesome Now! Got'r up to 60MPH!
After riding a few minutes the bike lost all power if on the gas.. I disconnected the Electric choke and It ran Fine After That.
Is the Choke supposed to be in the PUSHED IN position if ON Choke? or vice versa?
Thanks!

The chokes are 'in' when they are cold and 'out' when they are hot..
