Righto

Some know that I've had a couple if problems with the clutch on the curvy. Before Sid says it; yes I've adjusted the worm drive etc... And ended up back where everything was when I started.

I'm having to constantly adjust the clutch and its jumping out of gear when under hard acceleration. So is it the clutch or something else?

Thanks in advance

Have you adjusted it? :)

What makes you think the fault is with the clutch, does is slip, drag or grab? Is there difficulty in engaging or disengaging gears? What's the 'box like if you change clutchless?

Jumping out of gear wouldn't usually be attributed to a clutch fault specifically, but a draggy clutch can make the change difficult and mean the gear doesn't get slotted in correctly.

Yes I have, was on about 30 minutes with it. Wound everything back in and adjusted.
Its a little bit grabby going up the box and a tiny bit stiff going down.

Its jumped at load every time its happened recently.

I am with sid on this. your descriptions sound much more gear selection related.

As it is a curvy, clean off any corrosion on gear lever behind the fibre bush to make lever movement free and easy. Then set up your lever to ensure you movements are adequate to select.

What mileage/use has it had, just as an indicator to possible selector health which needs a strip to properly check

Check the gear lever. Make sure you're putting it in gear properly.

Shift without clutch going up... if it still jumps out then it's fook all to do with the clutch is it...

well if it's jumping out of gear then more than likely its a bent fork selector in the gearbox.

If it really is jumping out then a possible fault would be rounded dogs.

But I think it's not established yet what the actual fault is - over to you Andrew.

Done a run with clutchless ups and it was smooth all the way through. Bit of a jump from the bike, but thats what normally happens

Bikes done 27k, I've done 24k of that. One or two know my riding style, I'm quick but its high average speed not point and squirt.
You on about the bushes from the lever to the shift linkage?

yes Andrew, when was the last time you greased the gear leaver linkages?

Be about a year ago, when the insurance used zero grease on the left footrest repair. Selector shaft will be about 2 years since it was greased

rearset to lever pivot should be greased every service as well as checking the linkage ball joints for movement.

i use spray white grease on all pivots at every service. what i like about spray white grease is its very runny then sets so gets into nooks and crannies.

No, the gear lever sits on a spigot. With a fibre bush between them. The lever corrodes, tightening the bush and making the whole pivot arrangement stiff. Disconnect the linkage and if it does not rotate easily you need to clean off the corrosion.


Remove the lever. gently lift out the fibre bush (You cannot source a replacement if you break it) and run emery round the hole to clean it up. a bit of grease and reassemble.
