vacuum piston not functioning
Written by jdoyle_53 on 6/26/2012 at 05:14 pm

Thanks Mike and “wynndungey” for your responses.  I will try the atmosphere
air test this weekend, weather permitting – I tinker under a shade tree.  A
bit of introspection: I have only observed the vacuum pistons at idle – too
timid to crank it up sans air filter; 400cc is sufficient for my riding –
maybe the left side is not contributing as it should.  At 70 mph on this
morning’s commute, a twist of the throttle gave a slight nudge in the pants. 
I’ll monitor mpg for a bit expecting mid 50’s.
 
Thanks again,
Jim
