This video covers the reassembly of the top end of the engine. See my prior videos for the start of this motorcycle rebuild and other parts of the engine tear down
The washer you installed inside with the chain idler is a crush washer that should go on the outside to seal it from leaking also reflected in the disassembly video, both my k0 and k1 engines are designed that way, you’re also missing the copper washer that goes behind the acorn nut
Alright, there is another mistake to revisit.
Clayton, I understand the valve timing should be set with piston at top dead centre or TDC which is the T line on the rotor, not F for fire which is used to set the ignition timing. It's worth double checking, I'm not here to criticise simply to offer help.
I view all feedback as good feedback. Next video is first start.
Free_Ranger , you are correct, T not F with the pin pointing to the top of the head
@@dalelandon & yes the crush washer goes on the bolt as you said. I hope he doesn't take our suggestions as a criticism, I just don't wish to see him damage his engine.
You missed the spring tensioner on the cam seal
When I try and put in my camshaft, it is ridiculously difficult, because the timing chain and timing gear do not fully lineup with the hole in the in the head. Is there anyway to loosen the timing chain so I can get the camshaft and easier. I tried tightening down the four nuts, but even then I couldn’t do it. Wondered if anyone could help
You need to remove the tensioner. It is the bolt on the bottom of the car that holds the spring. That will slack the chain.
