Ok here's the lowdown 2012 kx450f 60 hrs of woods riding on stock top end Leak down test 1% over 15 minutes Has spark and fuel No codes when hooked up to 12V and self check terminal grounded. Started fine about 20x on the last ride (northern AZ trails) Got home and washed it and now it won't do so much as backfire at me. I've cleaned and di-electric greased every electrical connection including the CDI with no change. Switched my tank over to buddies bike and it fired up so the pump isn't bad. I'm lost.
