Eric,
In all seriousness - we've poked fun at it here on the NH Lovers
list - but SeaFoam can clean out carbs and fix some goop issues -
particularly if you know you have a potential clog - a whole can of
Seafoam in a fresh tank of gas won't cause any harm and could fix more
of your idling problems. They recommend 1 oz per gallon for
'maintenance' but I've usually just dumped a whole can in filled up an
understood that the bike might not run right for a few miles.
