Thanks a lot. It doesn't appear to be using oil (I only use the bike occasionally) but you've given me some ideas to look at. Cheers. Colin.

Hello Can anyone offer a likely cause for a problem with my 1984 XS400 dohc. It starts on just the left cylinder until it's warm(ish) when the other cylinder cuts in. Only clues are that I can't check the plug as it's stuck (don't want to force it until I know where to go next) but connecting a spare plug shows it is sparking. It runs and starts perfectly when warm. Any suggestions much appreciated. Thanks CEG.
