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.

If BOTH plugs are oiling up, then its not just a broken ring or gudgeon pin problem.
Draining the crankcase to see how much comes out sounds like a good 1st step.

Wanted , a Gearbox for a Douglas S6

Has anyone in the UK got a S6 Gearbox that they would like to sell ?

Here is a link to a post with pics of the standpipe.

It sets the oil level in the timing chest and drains excess away to the primary chain. It is also the engine vent. I have seen these mistakenly blanked off to 'fix' oil leaks.

Thanks Eric, thats just what I need. Another question, this bike I'm working on for my friend doesn't have a primary chain guard, would there be any chance of you taking some photos of yours to give me an idea of what I need to make.

                  Cheers

That would be 39 teeth then. My bike has been in parts for so long I forgot what is what...

Hi Eric, Thanks

           I was meaning the other sprocket on the gearbox, the one the primary chain drives, any chance you could count the number of teeth on that one.

                           Cheers
