72' 350F idling high
« on: July 22, 2010, 07:24:01 AM »
When my bike is in neutral it's idling at around 3000rpm.
Any suggestions as to what's happening?

ok, thats too easy.  :D

but seriously. 
do a full maintenance on your bike yet? if not.  get it done, first.

then probably need a good vac synch of your carbs.

sure thing, if all maintenance is in order, 350f's, when warm, should idle comfortably @ 1100-1400 RPM   :)
