5,200 miles.
I finally got it all cleaned & put back together; between family, weather, and shipping time, it runs great again.
I took the gamble and went through an online seller to save money; a $10.00 after-market petcock instead of an $80.00 OEM.
I did read a few negative reviews on the after-market ORings; I compared the ORing in the kit with a Honda ORing that I bought for a back-up; they look & feel identical.
The stock ORing that came off the tank had a 90° edge (more like an intake gasket)...
No leaks; ready for Spring forrestry work.
