Question - please help a newbie
This is great. Especially the pictures help.
Two weeks ago, I started my own project and I'm totally new at this, so I need some help. I heard a clunk sound every time I started the bike and it would go away once the engine warmed up. Talking to some neighbours, they said it could be the valves. I also noticed a leak and thought the cylinder head gasket was cracked. So, with the manual in my hand and some new tools I took on the task of taking the engine apart. Now, here's the weird thing. I checked the valves and the clearance was fine, so I took them off to get to the gasket. Unfortunately, the new gasket didn't come in on time, so I had to wait a week. During this time, the valves were just sitting in my shed. Once I got the gasket, I started putting everything back together. Before putting the cover back on the valves, I thought I would check the valves again and ... there was no clearance anymore, nihil, nada, zero, nothing. They were all slammed close to the cams ... I talked to the neighbourhood mechanic and he thinks it's because they sat in my shed without pressure from the top, that the "springs" expanded, and/or that the oil pressure was gone ... I find this very weird. Plan is now to continue putting everything back together and turn the camshaft a couple time to get the oil topped up in the engine.
Anybody have any ideas?
