Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

good afternoon, having a few probs with t6, have given front cylinder a de coke and new exhaust valve and showed 75 and 80 psi on both cylinders. Started bike up yesterday and ticked over for a few minutes after which front cylinder was very hot and back one a lot cooler. Now find that compression is so high that can not kick over even difficult to get it over top dead by using fly wheel by hand. Grateful for any advice on whats causing this, Derek

Let me guess that it's not compression that's stopping the engine from turning - check that you don't have a stuck valve. Let's guess front exhaust?

If you're going to run a bike on the stand for more than a minute on a warm day, use a fan to blow some air on the cylinders.

thank you for reply Leon , will take front head off at weekend and check. New valve i got from club is slightly longer than original and also does not have slot in the end to be able to screw in so was a bit fiddley all the best derek.

ps, when i took valve inspection covers off and turned fly wheel over springs etc seemed to working ok.
