The fuel petcock on my 4-liter Happy Time tank plugged up on my last ride. Couldn't clear it, so it was ride-then-stop, ride-then-stop to get home.
I ordered an SBP petcock and fuel filter a few days ago, then installed the valve today. After filterscreening the tank's gas, didn't find any crud in there. I peeked down the petcock before installing it. It has a HUGE port, almost the size of the brass hose fitting. This valve will NEVER plug up.
My FRAM automotive filter filled VERY quickly, when I opened the petcock. This was MUCH better than the OEM valve. Usually, I'd have to blow air thru the neck to force-feed the filter.
This SBP fuel valve is an EXCELLENT product!
