    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.

a gsx 250 came into my possession recently , i thought there'd be trouble when i saw the plugs had been left out & the bike left outside .trying to turn the engine resulted in no movement , ive stripped the top end off & found water & rust. managed to get everything moving except for one of the pistons, ive given it plenty of penetrating fluid & am going away for 2 weeks so am going to leave it. what to try next when i get back ? heat, hammers ? if still no joy. mike

Even if you manage to break the piston free, there will be a NASTY line in the cylinder where the rust is/was.

Your best bet is to find another engine.

well, i've managed to free it using a big hammer & a lump of hardwood. i think i also know why it was left open to the elements as well, one of the exhaust valve ends had become mushroomed over for some reason & obviously wasn't opening properly. the corrosion in the bore is quite bad, does anyone think a half mill re-bore would clear it ?
