Do she run rough and blow black smoke? After my desmog I had one vacuum line left for the petcock. When the diaphragm holed it sucked raw fuel into #6-left rear-and fouled the plug out. The old diaphragm had a serious sized hole in it. Since the rebuild of the petcock-new cover set-my M P G is mid 30s pulling my trailer and high 30s just the bike. Course keeping the tach right at or just under 3 grand is the trick!
After the rebuild she also idled a LOT better-especially right after start up.
After the rebuild the vacuum line is now hooked to #5-right rear much easier to R&R during tank removal and install. Thanks Atticrat and da prez! 17 years old 121000+ miles showing guess I'm gonna keep her a while longer!
I KNOW some of y'all HATE the stock petcock but this is more along the line of an F Y I. RIDE SAFE.
