So, I finally got my bike running well, but discovered some problems that need to be addressed. I've got a pretty severe oil leak coming from the cylinder head, as well as the shifter seal. Frankly, I'm surprised because I was diligent about how I assembled the engine. I had the cylinder head checked and it was flat. My machinist gave it a I have a new gasket, and I torqued down the head to spec, tightening it in the pattern the manual recommends. I'm at a loss as to what could have gone wrong. The shifter seal leak is easy in comparison and I've already ordered a replacement.
Another problem is the chain. It's a brand new D.I.D roller and I can not keep it tightened. The axle is not budging- the tensioner bolts are holding tight, but every time I ride the chain becomes loose. Is it possible it's stretching that much, that fast?
I did dodge a bullet with another problem. There was some loud valve noise, so I opened it up for a valve readjustment. In the #4 intake I discovered the set nut on the tappet had completely come off and the adjuster screw was hanging on by the skin of it's teeth, held in only because it was hitting the tappet cover. The nut was sitting down in the chamber next to the valve spring. I fished it out and adjusted all the valves. Unsurprisingly, it runs a lot better!
F*ck me.
