    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...

    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've seen a handful of front end swaps on 78-79 GS1000E&S models with 2004-6 GSXR front ends, but no 79 GS1000L (chain drive) swaps. I'm trying to figure out if anyone here is familiar with the differences in the L & E/S frame. Head tube angle is really the most important thing. Point me in the right direction. Any info is always greatly appreciated!

Head tube angle and length is all the same..

The only difference is in the triple tree offset and the legs... No rake vs the neck to speak of..

L is on top.. E on the bottom.. note that the L tree has less offset to compensate for the leading axle lowers.

I took the time to measure rake and trail on my E forks and the L forks..
he L trees have less offset, longer legs and the leading axle but when you put them all together the rake and trail are identical to the E forks.
 
wow, this is exactly what I was looking for in an answer. I thought in my mind that the wheel hung out a bit farther because of the axle offset, not realizing the triple had an offset to compensate. At least a GSXR style front end swap won't be any different then, but I'm think I'll hold off on it as long as possible if the rake is already similar to a stock E. Thanks so much for the info and the photos!
 
That's a really good bit of info. +1 to the japanese engineers no?
