I have just fitted new friction clutch plates to my Z1000A1, as it was slipping at high revs. When fully engaged the clutch is now working great, but it is juddering/binding when trying to ride the clutch to pull away in first.

Any thoughts ?

Thanks

Chris

did you check the basket for groves were the plates slide ?

Did you soak the plates in oil over night before fitting

Sounds like drag because the clutch isn't fully disengaging due to the added thickness of the new plates.
You need to slacken off the clutch cable at the bars and take up the initial slack on the pushrod via the adjuster in the sprocket cover.
You should also soak the new plates in engine oil overnight before fitting.
Fitting them dry can cause excess wear of the frictions and overheating of the plain plates causing them to warp which will cause clutch drag also.

Also check plates are free to slide in the basket,sometimes they can be a little stiff and req dressing with a smooth file...you are not using car oil by any chance?just a thought it might be that causing initial slip...

I dont want to be a bearer of bad news, but it sounds like it could be the tension springs in the clutch basket.

I had similar on by zed thou, & it turned out to be one of the springs had broken.

But it wasn't doing this before I replaced the friction plates, so I would be surprised if a sping had broken.

I didn't soak the plates in oil before fitting them. Could I have now damaged something by not doing this or do you think that if I take them out, soak them as you say then refit the problem will be solved, with no detrimental affects ?

Thanks

You might get away with it if you haven't been far.
Give the frictions a very light scrub on a flat surface (concrete paving slabs are good for this or fine wet and dry on a mirror etc ) to remove any glaze then soak overnight.
Check the plain plates for blueing and warping.
Re-fit and re-adjust any slack at the pushrod before moving on the cable and you should be ok.

Hopefully you'll get away with it, just inspect them for damage when you take them out.

Then soak the cork plates in engine oil for 24hours before putting them back.

There was no problem with operation when the clutch was depressed during normal operation, just in first when trying to pull away. I did do about 20miles, but as I say the only problems were at the occasional junction.
I will do as you say and hope for the best !!!
There was no mention of soaking new plates in the haynes manual !!!

Thanks for your advice.

too true there Chris
haynes manuals are rubbish
Evans buy Yourself a Clymer manual much better information

evans, wot oil are you useing? As we know must be mineral or semi synthetic.

Some years ago had a Z1B with new plates fitted, mistakenly put in synthetic, had same prob as your described, slipped/grabbed on launch only in first gear.

Have you got anywhere with your crutch issues ? (update)

I have soaked the plates for a week and just put them back in, seem to be able to pull away ok now. How do you adjust the clutch with cable and the push rod ?
