Installed SV650 clutch perch; now the clutch will not disengage, I think.......

[tialloydragon]

Hello,

Yesterday I installed a set of SV650 adjustable brake and clutch levers on my GS500.  The PO installed an old SV650 master cylinder, so that swap was really easy.  The SV650's clutch lever is different from the GS500's, so I bought a SV650 perch on ebay and installed it.

I knew that I would probably have to adjust the clutch cable because of the new clearances, so I had the bike up on its center stand, started it up, pulled the clutch in, and put it in gear.  As I suspected, the rear tire started spinning.  It was getting late, and I had to go to a birthday party, so I left it until this morning.

So I spent the last hour playing with it; tightening and loosening the connections at the lever end and the case end.  It seems like it doesn't matter how tight or loose the clutch lever is set, the rear tire will still spin when it is off the ground with the clutch pulled in.  Right now I have the lever set with the standard ~4mm of slack before resistance.

Does the rear tire still spin a little, while in gear, with the clutch pulled in, regardless of whether the clutch is adjusted properly?  I can stop the rear tire with my hand, and it stops spinning until I feather the clutch.  After that it continues spinning until it is met with resistance (either friction from my hand, or when I sat on the bike and let the rear tire touch the ground.)

This is my first experience with clutch adjustment, and I haven't tried driving it yet.

Perfectly normal. Go ride.

as PAULCET says ,it is the cold oil causing it to turn .it will some times do it when oilhot







DO IT YOURSELF BE SURE ITS DONE RIGHT

these are wet clutches so even if the plates are not engaged the fluid drag will still transfer torque to the wheel.

so gear in, clutch in, no load on the tire; that small amount of energy is enough start the tire but you'll notice is very easy to stop. the weight of the bike on the tire is enough to prevent it from moving while on the ground.

im not sure if dry clutches still maintain a very slight drag while disengaged too. then they would also do the same. anyone have a ducati? lol

Yes, its normal behaviour for a wet clutch, stop worrying. Dry clutches have no residual drag when disengaged but in wet ones the oil on the plates transfers a very small amount of torque. Just adjust the clutch as per the manual and go ride.

This is your first experience with clutch adjustment. You just spent an hour (or more) trying to get it to do something without knowing if what you were trying to get it to do was right, or if what you were experiencing was normal to begin with?

Have you learned now to bone up a little more on the topic at hand before going off half cocked? 

Just Ride.

OH... you also may on occasion feel the bike Slightly lurch forward when cold and first put into gear. Like the spinning wheel on the center stand, this is normal.

Ouch.  I will try to read up on my physics and fluid dynamics the next time I turn a screw and post a question.

I remember adjusting my first cable on a wet clutch system. I noticed that, scratched my head and took it for a ride anyway and adjust it by feel as I rode. Put on the stand saw it was still there scratched my head for a second more and rang a mate who said yes they always do that. I was going to leave it as is cause the clutch felt right. Mind you that was the bike that took the skin and meat from my thumb.
