Guys,

I pulled off the rear sprocket to have a look at it since its done around 15k kms and was never cared for by the previous owner. Needless to say the chain was making a racket and the 42t rear Sunstar sprocket now has about 5-6 teeth less!

The Entire mag, Hub/flange, chain/sprocket kit is after market and im kinda in a soup since i dont know where i would get spares if something were to happen.:rant:

Did I mention in Live in india where blades like mine are very rare and spares even more so?

Could some kind soul please help me out here? I dont want to order incorrect parts since i live on the other side of the globe and shipping/customs cost a bomb!

Also, im looking for a chain/sprocket kit on a budget. The bike isnt used much and i dont ride it very hard- thus i dont want to spend on fancy stuff. Im just an average joe on a shoe string budget. :p

Some additional details of the current setup.
Rear sprocket- Sunstar RK-111 42t
Chain- DID 525 Gold (108links, I presume)
Front sprocket- Looks stock with 16 teeth iirc.

P.S Does anyone recognize the brand of HUB/Flange? and the mags?

Cheers!!

The wheel has no writing on it to identify it?
Maybe Duomo or Marvic?
What is the centre bore of the sprocket?
Early Kawasaki have 104mm bolt circle diameter so maybe check your measurement.
If you get any sprocket that has the same bore size you can simply re-drill it using yours a pattern - this is how I make 520 sprockets for my '85 GSXR among other things.

As always, Bladeracer to the rescue!:thumb: Thanks for the quick response mate!

The wheel just has forget aluminum written on it. Its very light and and has taken some serious torture over the last decade.
The bore size is 79mm. Your iea of re-drilling the holes is fabulous. Any recommendations on a cheap yet reliable sprocket with a 79mm bore dia? Im unable to do much research on the same as most of the sites are blocked by my ISP for reasons best known to them!:mad:

If it says it's aluminium then it's clearly not a "mag" ;-)
79mm doesn't ring any bells but 80mm is very common and would fit for sure.
I would try the Kwaka sprockets as you can probably just dress the holes with a round file and it'll pop on. Late ZX10R has the 104mm/80mm but with 10mm bolts, so it might just go straight on. Older models in the "Z" and "KZ" range run the same pattern.
No idea what would be cheap where you are but any of the name brands would be fine - Renthal, AFAM, Vortex, JT, etc.
I would go to 520 stuff rather than keep the 525.

Lets start with the old chain/sprocket set.

The New and old

You can clearly see the damaged teeth here.

Had to fabricate a tool to flare out the chain link rivets. Not sure if they have been flared out enough. Seems ok to me- Quite close in dia to the other rivets

The end result

Hi All,

Can someone please tell me what these bolts are called and where i could find them?

bolt 2.jpg

They hold the rear sprocket to the flange. The thread has worn out and the hole in the sprocket seems to be a whole 1.3mm larger than the OD of the bolt. I have a feeling the sprocket is floating around a bit when I suddenly wring the throttle or roll off it. Either ways, I need to replace them preferably with one that fits the hole in the sprocket well. Please advice...

Also, what is this type of hub called and where could I get the rubber bushes?
