Worn gear dogs will actually jump out of gear into a fals neutral - sometimes causing a horrible clatter - other times jumping from one gear to another.

Slipping is usually a sign of a worn clutch.

Could you describe the problem in more detail?

When hard on the power in 2nd only there is 2 times it does it once at 7-8k and again at 11 but no other gear.It feels like it slips then grips again then fine.I did replace my clutch cable other day,because when out last sunday it snapped.But before it did snap on the way out to wales is the first time i noticed it.It just seems to have happened rather than creep up.Strange indeed and worrying

It sounds more like a clutch to me. 2nd gear has a higher leverage ratio, so this could be your early warning sign. It's a whole lot easier to start with the clutch. Cheaper too!

+1 on it being your clutch. Gears don't slip..clutches do. If your gears did slip that would be the end of the rest of the gearbox as the teeth started to grind off and interfere with the lovely engineering inside the casing..

I replaced my clutch last year and it was tighter than a dick's arse. Afte a week it almost gave up compared to what the inital feeling was..but it just needed a little tweak on the adjustment to make it solid. The clutch feels long now but it does ont slip at all.
I fitted an extra diaphragm spring and EBC race plates.


I thnk if I was going to take some motor advice from anyone on here then Mike would be that person..go and have a look at his website..

I don't know what the problem is but a mate of mine has the same thing with his '94 GSXR 750. If you gun the throttle in second, between the 7-9k rpm and at about 11k rpm it, well hiccups. The revs don't shoot up or drop (which is what a slipping clutch would do). I have to say it feels as if the gear dogs, slip one notch and then dig in again. It's also a bitch to get her from 1st into 2nd and viceversa.

Thinking it was a clutch problem at first, we swapped the plates, steel plates and springs, also filled down the clutch basket a little but this made no difference

Sounds exactly like my TDM's 3rd gear, the cause was a combination of selector drum wear

and rounded dogs (original one on left)

I stripped it down and replaced it with a 17k gearbox (the TDM has 63k on it), must finish it off one day, I keep fettlin NC35's instead...
