NGPZ: Idle oddities on range bikes

I didn't know WD40 could be used for a vacuum leak analysis, I've always
used carb cleaner.

While you could have some partially plugged pilot jets, it sounds like they
might have vacuum leaks somwhere. Either the intake manifold the carb fits
into could be loose and it's sucking air or the carb is leaking air
I'd start by spraying WD-40 around the intake manifolds while the bikes are
runing and see if the idle increases, if so it's an intake leak. Otherwise,
check the cap on the top of the carb to see if air's getting in and
affecting the CV bladders and anywhere else there could be a leak.
