    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Took the bike for ride this afternoon on returning back noticed some petrol on the swinging arm (oveflow pipes stretch down to in front of swinging arm). Decided to remove the overflow pipes off the underneath of the carbs. Started the engine and watched the overflows noticed that No1 carb intermittently say every 30 to 40 seconds so and a for a short spell ejects petrol. Has anyone any idea what this could be.
 
take the needle valve out and clean it, may be a tiny bit of dirt in there holding it open. replace if it looks dodgy! also check the float height, lower it by 1/2 - 1mm if it is on the high side of spec.(lower the height by increasing the float measurement!)

Will check it out tomorrow Adrian, had new needle valves last year. Odd that it does not overflow all the time, just every so often for a small amount.

Think you mean... increase float height, to reduce fuel level. Yes?
 
Thanks for replies, have cleaned the needle valve and adjusted the float height a touch and now all looking good. :)
