    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...

Chain/sprocket replacement '78GS1000

I'm replacing what look to be the original chain and sprockets on my GS with a 630X96 DID O-ring and Sunstar front (15) and rear (I ordered 42; they sent a 40) steel sprockets.

Two questions: Anyone tried running a 40-tooth rear sprocket? I'm assuming it'll make the gearing a little taller. And (b) this'll be my first chain and sprocket replacement. Anyone have any golden, or merely sterling, advice about the process?

Thanks in advance,

Jack
 
Remove the front sprocket NUT before you take everything appart
 
I have run the taller gearing many years ago when I had a sports touring fairing and did a lot of interstate trips. It makes higway travel more relaxed as less rpm. I don't remember it improving or changing fuel economy in any noticeable way.
