I'm amazed it ran that long, especially seeing the state of the cam bearing surfaces. I assume it's a full engine out and strip to clean all the cag from the oilways and oil pump. Good find with the new head.
Nope. Just swapped the head complete, set the valve clearances, filled it up with oil and water, good to go.
No regular updates because incredibly, there is nowhere in London with a head gasket in stock. The very next thing is to bolt down the new head so until I source a new gasket, the mission is on hold. I had hoped to reuse the old one but it looks like that has already happened a couple of time and it's looking a bit flat (!).
I have cleaned and prepped the new head though. I'll try linking a few pics but photo bucket keeps claiming I have run out of bandwidth. A scam no doubt designed to force people to pay for this so called free web service...
The exhaust stud which fouls the frame on assembly came out a treat.
Should be running again within a few days, subject to sourcing a new gasket. Fifty bloody quid mind from Yamaha...
