    A Special Note about Email accounts!
    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    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.

Four coils?

I'm changing the fork oil seals on my GS1000G as soon as the new ones get here. What sort of fork oil is best (for normal riding, nothing off-roady or racy, just long-distance good roads, with me (190lbs) and minimal baggage.

I ask because on Triumphs, even a very small change makes a big difference (ATF is stock, and if you go up to say 15W, it makes the forks a lot harder, and 20W makes it feel like it has no suspension at all. I don't want to go through a load of waste and unnecessary mess by failing to get it right first time!

Four Coils = Fork Oils
 
I'm 215lbs and 15W is fine for me on good roads. I'm blending atf and 10W40. There are recipes out there for what proportions to use. The atf has a disproportionate effect on the final viscosity. A 50:50 mix of say a 10 atf and a 20 motor oil does not give 15, more like 12. I am flushing the forks fairly often as there is a lot of crud in there. This way I get to experiment and it's cheaper than the hi-tech stuff.
My garage is lit by fork handles :)

It's gonna be 10w or 15w and what you plump for will be your own preference. I've got 15 in all of mine and I would say the ride is firm but in no way harsh and I ride at a decent pace with the odd burst when I forget I'm no longer a teenager, if that helps.

10W for me then, I reckon. I seem to have a dislike of stiff-feeling forks. If 10W is ok for some folks, I reckon I'll be among them. Easy enough to alter if necessary, but this will be my starting point.

The 2 Ronnies were great, but I'll admit to being far too old and cynical to take them as my primary source of GS advice!
