Fingers crossed

After doing the rounds asking the big questions, the brains trust is banking on the fly side seal. I can pull the choke out and the idle doesn't change, dropped the gear oil, no fuel smell this time round after the clutch seal was replaced last time. I read today another way to check for an air leak was to tape up the clutch breather and see what happens. I just replaced the fly side seal, getting the other one out wasn't pretty. I whacked everything back together, filled the oil back up and decided to leave it until tomorrow. Bit of luck I can tune it in tomorrow and ride it to work on Friday, riding my push bike is fun and all, but...
