    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.

I rebuilt my gs1000 and put in a wiseco 1085 kit.
I checked the compression cold before I put the
pipes and carbs on (I know you are supposed to check it hot
but I just wanted to get an idea before I put it all back together).
Anyway, I got 135,125,118 and 135 psi.

On 1 and 4 I got 135psi on 3 turns of the engine and it took
5 turns to get the 125 and 118psi on 2 and 3 cylinders.

I put about half a cap full of oil in the 2 &3 and rechecked
and got 155psi after 3 turns of the engine.

My ring gaps are within range, could I be getting low readings
on these cylinder just because I have a fresh hone and my rings haven't
seated yet?

Also I remembered after I put oil in them, that most people recommend
dry cylinders for break -in. Won't most of the excess oil burn off
when I fire it up? Or should I pull the head and wipe down the cylinders
to try to get it dry as possible? (I'd really rather not do this unless
it's really necessary).

Thanks in advance

Low readings cause its not broken-in yet, pull the plugs crank it for a few seconds with some rags over the plug holes so oil won't get all over, this will pump most of the oil out, and leave enough to lube it while trying to get it going, dry cylinders are NOT a good thing on a new motor, you just dont want to much oil or gas in the cylinders or you may wash the rings out
 
I'll give the rag thing a try.
Some people suggest dry cylinders so that the
rings seat better against the freshly honed cylinders.

Thanks for the hint.
