GPZ500 sticky clutch

[Benno]

A about 2 weeks ago when I bought it, I rode it up the road and back, got up to 3rd gear, all fine. Seller warned me the clutch can stick and you need to give it a good kick to get it into first when starting up if it is cold and has been sitting a while.

That seems to be what is happening. I can't get it into first without it lurching and stalling. I've just made a number of attempts. Additionally there is a whining sound after several attempts, which seemed to stop when I opened the fuel tank.

tl;dr how to fix sticky clutch? (If that is even the problem)

Had a suggestion from a mate who used to own bikes:

- Drain and replace oil
- Run engine on idle to circulate oil, turn off, top up oil
- Turn back on and run engine for 10 mins to warm up
- Place front wheel against sturdy wall
- Hold in clutch and front brake
- Drop into second gear and release clutch

They all do that, mister. Well, mine does, both points.

It's had a recent oil and filter change and there's 5100 miles on the clock.

Brakes on hard, clutch right in (tighten if necessary), rev it like you mean it, and kick it into 1st like a naughty puppy.

Whining is just the tank breathing. Heck, it'll do it if I so much as nudge it.

As Roger says, they all do that Mister. The plates stick together if they're left standing more than a couple of weeks. Easily sorted.

Start and warm up engine.

Place bike on mainstand.

Stand astride the bike and hold the front brake on.

Pull in clutch and engage first gear but keep holding that clutch and, the rear wheel will start spinning in the air (see why you're astride the bike and still holding the front brake on?).

Once it's up to speed, slam the back brake on hard. The rear wheel will stop and one of two things will happen. 1) The engine stalls, try again from the start. 2) The engine does not stall, your clutch is freed off.

Mine does it a bit (nowhere near that bad, a bit of a jerk forward) but I find giving the clutch a good working before I start it up (or put it into first) eases it off a bit
Actually, I left it a week or so on holiday once and nearly ended up in the back garage wall now I think about it
Also, you probably won't be able to get second if you're not moving thanks to the 'Positive Neutral Finder'. So don't worry about that if you can't

Thanks chaps, I was worried it was more serious than it was when I heard the tank whining. I'll post results tomorrow.
