Is it a cable or hydraulic clutch?

Changing the position of your lever will help a lot. Sit in your normal riding position, stick your fingers out straight in line with your arm try and get the lever on the same angle as that.

I went out on Sat came home struggling with the clutch. Managed to get out before changed the position, went further and not had a issue today.

I'd do what theshrew suggested, but also has the lever got a span adjuster? If not, you could try adjusting the cable so that the biting point in with in the strongest part of your stroke? (sounds very wrong hehe)

This, the PO of my old GS650GT (now sold but not forgotten) had put heavy duty clutch springs in it and after about half an hour riding I was in agony, ordered some new Suzuki springs, problem solved.

As above. I came back from a long ride on my ZX6-R almost unable to pull the clutch. I adjusted the lever down a bit and all was good.

Also I forgot to mention if you are adjusting the lever you might be able to move it up and down the bar. Shove it up towards the middle of the bike then you will get more leverage.

Maybe you have a woman's hands? biggrin

What sort of clutch actuator does the bike have, is it the re-circulating ball type? These do get much stiffer with age and wear, we fitted a new one to my dad's SV650 and the clutch weight was hugely reduced.

WTF do people by heavy duty springs for? especially with a standard clutch, it's hardly like they are going to be towing a lot like idiots use as a reason with cars.

Sounds like the same type of mechanism as the SV. Internally there are coarse spiral 'threads' which run on ball bearings. They are quite exposed to water and crud from the chain so the bearing surfaces eventually get worn and pitted and the friction increases considerably.

Have you completely stripped, cleaned and re-packed this mechanism with fresh grease? Doing this did improve the clutch action on my dad's SV, but it was still heavy and fitting a complete new mechanism made a big difference. The clutch springs are likely to be a cheaper initial purchase though.

The other thing that makes a big difference is correct adjustment. If it's like the SV there are two points of adjustment; one on the outer clutch cable and the one on the clutch mechanism/push rod. First back off the adjuster on the clutch actuator. Then adjust the cable until the inner cable and the operating arm on the clutch actuator form an angle of just less than 90 degrees. Finally adjust the push rod clearance with the adjuster on the mechanism (screw in until it just starts getting tight then back out 1/4 turn).

The idea is to ensure that the inner cable and operating arm remain as close as possible to 90 degrees (and therefore maximum leverage) throughout the normal clutch operating range.

The clutch basket itself isnt won as well is it?

Like in the picture below.



This will also cause the symptoms you describe.

The basket nut is fine, you sometimes find a gearbox sprocket is held on by a similar tab washer arrangement.

Thinners is brill for getting rid of any remains of gasket and to soften it initially.

Also check the clutch push rod from LC casing of the bike, these can end up getting gunked up, which wont help your cause.

If it was me and with my experience of recent, i would use a genuine Suzuki item on this crankcase cover and not a pattern one.

Im sure you'll crack it.

If the gasket surfaces are pretty much perfect you shouldn't really need gasket sealant. However, as a belt and braces approach you can use a thin smear of a non-setting gasket sealant, such as Hylomar Blue.
