The on position on my peacock does not let enough fuel to flow to get above 30 mph. I have to switch it to prime to run at speed. I looked on bike bandit and the petcock has been discont. I don't really know where to go to find a replacement.
Well, if you have to do that, then you'll also have
to put it back to on when ya park the bike. Otherwise the fuel will keep flowing, even when not running.
Did you check
part# 51023-1392 - TAP-ASSY,FUEL $57.41 (2006 model)
part# 51023-1113 - TAP-ASSY,FUEL (1986 model)
(I don't think Bike Bandit gives the last 4 numbers though)
There are also other model years with different part#'s for the petcock, but #51023-1392 supersedes them all (according to Ron Ayers site anyway).
You should be able to use that one, which is one with reserve, not prime.
Or, like Fergy said, see about rebuilding the one you have.
I'm not sure what's needed for that though.
Did you check the vacuum lines (I didn't really think of that wwmkwood
