Installed the new $10 fuel petcock...
I knew my OEM petcock was leaking. I found out last year when I was doing some investigating of some bogging issues my bike was having.
I bought the petcock rebuild kit...against the advice of several people here...and discovered exactly what they warned me about; that the leaking was actually WORSE after the rebuild.
Anyway, I also picked up one of those cheap Chinese-made petcocks thats designed for the Kawasaki Quads, but fits our bikes. I think it was $10 from Amazon.
So, I installed it today, but I had to make two mods first:
1. I hade to removed the thumb lever and grind it down so that it would flip to "on" without hitting the seam of the tank. 5 minutes on the grinder solved this issue.
2. I had to use a screw-type hose clamp because the main fuel port is smaller diameter than the OEM petcock. Thankfully, I have hose clamps.
First thing I noticed after install was that fuel was no longer pouring out of the petcock when the bike was off. The next thing I noticed was the I didn't smell the stench of gasoline, which was a byproduct of the fuel pouring out of the old petcock.
The third thing I noticed was that the bike started right up and idled/rev'ed smoother than before, even though it was still cold.
This is curious to me since the carb should have properly metered the fuel coming out of the petcock regardless of how much flowed out, yes?
At any rate, I can't wait to take it for a test ride. I might have a small window before the rain comes.
