650G clutch springs

[duaneage]

My 650G started slipping on 4 to 5 shifts at high speed. I ordered new clutch springs on a hunch and it turns out the old springs were 5 millimeter shorter on the bench than new ones. I had a burnt steel disc as a result.
Fortunately I had a few spares steels.
Springs are cheap and worth replacing if yours are original.

Put new Suzuki springs in my rebuild ... haven't driven it yet so I can assess the results yet. Will likely be driving it in the coming week or two. Pretty easy procedure.

I found mine to be about .080" shorter in free length than the new replacements. The springs are cheap to buy. I think that anybody who is taking the clutch cover off should have a new set of springs ready to install.

I was also getting some occasional clutch slippage at higher rpms. Early this year, I installed a new set of OEM springs. That eliminated the slippage. Still a trace of two stage engagement, mostly from a stop, on anything but a rapid clutch release. I believe the plates should have some attention this Winter. I didn't measure the spring length difference between original and new but there was a noticeable difference. Probably at least 2 mm.

This is all a very good discussion on clutch springs, but I did not realize that the 650G was a two-cylinder bike.

[Mr.humbucker]

I believe they came out with a 2 cylinder in 83 branded the Tempter GS650. Not sure if they continued to make the four cylinder model too in 83.

Just for the argument, the Suzuki 650 Tempter was a 2 cyl. & named a GR650, not a GS. Best I can recall all GS650's were 4 cyl.

Looks like you may have forgotten about the GS400 and GS450's.

I do forget a lot. Now,,, how has the GS400 & GS450 slipped into a conversation about GR650's & GS650's? What'd I miss?

What does that term refer to? I haven't heard it before regarding Suzuki clutches.

Likely a poor description of a slight issue. When engaging the clutch, there seems to be a slight delay from partial engagement and full engagement. With lever fully released. Sort of a "2 stage" effect. From a stop or on some upshifts. Not noticeable on more rapid upshifts. New springs alleviated some of it, but I probably need to check the plates.

might be gear lash...not clutch.

I had to read through all the comments and posts, I'll try to comment as they progress.

This was apparently in reference to the fact that this is posted in the 2-cylinder Engine/Drivetrain/Clutch forum.

Introducing the idea of the 2-cylinder GR650 Tempter. Yes, they DID continue with the 4-cylinder GS650 in 1983.

This is true.

Looks like you may have forgotten about the GS400 and GS450's.

This may have been a reminder that not all GSes were 4-cylinders by mentioning the 400 and 450, but was incomplete by also forgetting to mention the GS250, GS300 and GS425.

Can you follow the train now?
