Looking for a 530 front sprocket with or without off-set for J-type motors with 17 teeth on it please.

AL

530 is the way to go, my Z1 has had 5310 X-ring on for over 10 years, works much better thatn 630. I use either Z650 16 tooth or an 18 tooth of a kawasaki VN800.

I would suggest a trawl through :-

When I last started to put together a guide, I found quite a few options for the 'J' motor sprocket.

good luck

Simon

Thanks Simon. Had a good look through. The early ones Z1 A B 900 A4 / Z650 use a Z13 format for the front spline, J / GPZ / Uni uses a Z12 format for the spline.

AL

i think zzr11 is the way to go for 530 with a little offset

Thanks j.b that may well be the answer.

I got a 530 17 tooth offset sprox for my J from jeff at z1enterprises.

Thank you gents plenty of suitable alternatives to be had if you know where to look.

Thanks again

Beware!

The true offset measurement is that 19mm MINUS the width of the actual teeth which would make it around 12mm ish ?

Offset should be measured from inner to inner or outer to outer face, not inner to outer as in pic.

Youre right Rob and it was me that introduced the subject of off-set with regard to that measurement.

Also relevant is the thickness of the core as i have found out. Not all these sprockets have the same dimension there which leaves the splined stub protruding a little and the sprocket even when tightened slops about on the output shaft causing it to need a spacer behind it which is what i have had to do.

Have also discovered that my sprockets are not in line either.
Meaning; no amount of spacing at either end will put them in the same plane!!!

AL

There should be a sprocket nut that is recessed at the rear allowing it to tighten on the sprocket and not the spline ( I have a couple on the GPZ and 1000a gearbox's)
There is usually also a corresponding tab washer in that situation which locates on the spline and folds on to the nut to lock it.
You can use more than one tab washer at a time to 'shim' out the nut if the spline still interferes with just the one washer on.

The J has a bolt in the centre. The sprocket core must extend beyond the end of the splines. The bolt has a fixed broad shoulder washer and beneath it a large spreader washer.
The non J specific front sprockets appear to have a thinner section at the core hence the need to pull the sprocket outward, flush or beyond the spline shaft using a spacer behind it.

At least that is what i have found with the sprocket that i have.

All's well though as i can now get a wider rear section tyre in it

AL

Ah! Yes.
Was forgetting about the J's bolt.
Would be a good idea to turn down an old sprocket and make a splined spacer washer to make up the difference.
