Most motorcycle problems are caused by the nut that connects the handlebars to the saddle.

Clutch removal

Post by badseeds on Thu 25 Jun 2015, 11:48 pm

My clutch has started slipping in 5th, a sure-sign it's dying. I have a low-mileage clutch in a spare engine, that's not in a frame. What's the best way to go about removing it? I have a VFR800 clutch holding tool, I've no idea it it'll fit, but there's nowt else.

The revs increase and the tacho spins round, but no extra forward thrust. I had the same symptoms on a TZR125, XJ900 and VFR800 - all had worn friction plates.

When clutches are dying they'll slip at speed - gunning mine in 5th at around 8k rpm makes it happen. It's fine for normal day-day riding, but chasing sportsbikes on the IoM has made my clutch protest.

If you're just going to change the plates then you only have to remove 4 x M6 bolts and the springs.
If you want to change the whole unit then I recommend something like this, using an old sprocket.

That's what I was hoping to hear, Andy. Cheers!

Slipping sounds the same as when my clutch started to majorly fail on my 125... 100 miles from home! Wink

the easiest way to remove the nut that holds the clutch together is a air impact gun, the sort that you use for undoing car wheel nuts/bolts.
