So, I couldn't get my KTM jetted properly - either is ran good and fouled plugs or I could make it run leaner but I ran into knock.
Here's what the inside of my exhaust pipe looked like:
Basically, I was pulling trans oil into the crankcase and fouling everything out. I had replaced the seals, but it still leaked. When that happens, it's time to change your crank bearings. While I had everything apart, I sent the crank out for a rebuild - good thing, here's a shot of the big end "pin" where the bearing rides:
note the ridge at the top and the spots where the rollers micro-welded themselves to the pin. This damage was only on 1/2 of the pin and probably contributed to the failure of my crank bearings (excessive vibrations).
Here's a few shots of the cases going back together:
I'll throw it back in the bike tomorrow. Hopefully I have fixed my problem.
