Whew! I finished reading the whole thread. It took me a bit more than two weeks, taking time out for meals of course.
I'm still waiting on the CRF cam chain, the carb is soaking in Pine-Sol, and I ground down the header welds this afternoon. I'll wrap the header tomorrow. Some folks will disagree with wrapped headers, but I experienced a nasty second-degree burn in my youth from having an unwrapped pipe lay on my leg after a fall. Yes, I was wearing shorts.
It's good to survive one's youth.
