Re: Clunky Box: Reason and Remedy
 

What has the clutch got to do with clutchless changing? It's not involved, hence the name 'clutchless'. There's nothing in the design of a clutch that can facilitate clutchless changes, it's gearbox design which could help with that.

You're not thinking of slipper clutches are you? Even if you are, they're still not 'designed' for clutchless changes, they're just a back-torque limiting clutch.

no but hes wondering why his box is clunking ie the thred title and said hes been doing clutchless shifting nothing to do with clutch i'l get my coat then and leave you with the fitters.

Re: Clunky Box: Reason and Remedy
 

Apart from what's been said,another cause of poor shifting is the gear lever where it pivots on the footrest.This needs regular lubing or it will get sticky and ruin the shift action.
Also,do you lube your chain properly?An OEM one should not fail at 6000 miles unless you got ripped off with a sub standard one?

Re: Clunky Box: Reason and Remedy
 

OK guys. This is really annoying me now.

I have replace the clutch cable and oiled/greased/lubed every single part that needs it on the bike. The Clutch is adjusted correctly. The chain is spot on (and going strong!) and I'm still having the same bloody problem.
This clunking is really annoying... is it time to replace the clutch plates? What else could it be?

Where abouts in London are you?

I might be able to lend a helping hand...

Re: Clunky Box: Reason and Remedy
 

Another thing to check is the actual gear rod bit where it attaches to the gearbox spindle from the engine. If this is loose the your gearbox will not be received 100% input for the gear lever.

its a 10mm bolt that should be accessible with having to take off the sprocket cover.
The SV does rumble so sometimes this can get loose if not torqued up correctly or maybe just with time?

If you touch your gear lever with your hand see if movement of the lever gives direct movement of the gearbox spindle.

Had a Curvy on 65K - 23K shoudl be nothing!

Good morning.

You don't mention whether you have problems selecting neutral when stationary. If you do have problems it sounds as though the clutch is dragging slightly. This could be due to the operating mechanism being worn, which considering you drive in London traffic is a distinct possibility.
I have seen gearboxes which are notchy even when the clutch appears to be adjusted correctly. This is due to wear on the mechanism effectively reducing it's travel, & therefore not allowing the clutch to fully disengage.

Cheers.

P.S. I think a new operating mechanism is around £30.
