G'day Mrkeung,

My bike starts out in the middle of the "hi and "lo" position. When i flick the run/stop switch to run, the rc servo cycles to "lo". After I kick start the bike, the rc servo jumps around a little until it finds it's idle speed at which the servo sits in the "lo" position. Once warmed up, the servo basically replicates the throttle position. Lo = no throttle/Hi = near wide open throttle.

Well that's what my bike does. Not sure about others...

pbekkerh's bike must refer to the forum, mine does what the pgm says to do.
