Basically, the worm drive turns the pull of the clutch cable into a push on the pushrod, which then moves the clutch plates apart. The screw adjuster adjusts/preloads the pushrod- if it's slack and not contacting the pushrod then there's slack to take up before the pushrod moves, which can lead to drag- the same amount of lever movement gets you less clutch. If it's overtight then the pushrod never quite returns to the neutral position, which can lead to slip- the clutch never quite fully grips

Aaah...so what is the benefit of 1/8th turn over 1/4? Making sure the clutch plates are fully apart when levers in or what?

Job done! a new cable and tuned adjuster, the clutch feels very nice

thanks all

It's just that it happens to be the right amount

Won't matter at all, the screw just pushes the clutch pushrod in the same way as the lever/worm does.

Ah cheers northy, I never dared! Thought it was safest advice until someone knowledgeable turned up.

Oh yeah, definately.

Cool Anna, I did mine for the first time yesterday, but wish I'd read this as I used 1/4 turn. I don't suppose it matters, the clutch feels fine.

For anyone needing an easy to print version to take out to the garage, exactly the same instructions with pictures are in the workshop manuals, page 18 of manual 2 (periodic maintenance) and they are available here www.sv650.org/sv_manuals.htm, buch better that the Haynes manual I believe.

Did the adjustment (screwed it in and then out a tad) - fiddled with cable adjusters to tighten cable, started engine, selected first, let out clutch, bike went nowhere.
Turned off engine. Repeated above but unscrewed the little screw a bit further and so on.

Repeated about three time until the gear finally bit...

You have a problem there by the sounds of it. I've always done it the "Anna Way" (nice summary post!) and it works fine.

When you did up the locknut after turning the rod out a 1/8 turn you did hold the rod still at the same time didn't you? If not it would have moved in with the turning action of the locknut and be way out.

I wentout with me nephew today (he is 11) to adjust the clutch on my bike. I had all theinstructions printed out and then my work phone rungso i had to leave the bike with my nephew in the garden....whe i came back the number 4 screww was completely untightened. i tried for over an hour to find the correct setup but with no luck....could anyone please help?

Many thanks in advance
