Chain Replacement

[oneyunguy]

Hi there,

Can anyone provide me with some feedback on some good o-ring chains they have purchased and used? Im a little lost when it comes to buying a good quality o-ring chain for my GZ. I will be replacing with like-original parts. Of course I also have to change at the very least the front sprocket, believe me, I do. Should I change the rear one as well, or can i get away with it if the teeth aren't hooked yet?

What is the pitch I would need and link #?
BTW: I'd be purchasing the parts from either Bike Bandit, or Ron Ayers.

thanks all!

Part #'s would be nice too if ya can. :2tup:

Will this be a big job? With the new chain, if it's o-ring, I am assuming it will have the "removeable link"?

Don't both those places have online parts "fische" available; pretty sure Bike Bandit does.
Get whatever they recommend. That should be pretty close to OEM.

Yes you should change BOTH sprockets.

Yes, it should have a clip-type master link because it takes a special tool and some patience to do a staked link.

Whether or not it is "a big job" depends largely on your skill and experience. If you need to ask, then it probably IS a big job.....for you. To change the rear sprocket, the back wheel has to come off.

Well, I DID manage to haul out the engine, re-do the whole cylinder with an oversized piston, check over everything else in there and put it all back together. Soooo, this would be something I can do, I guess just seeing if its something I would need specialized tools for or something like that.

The proper chain is a 520 link,20 pitch length (12.57 in).I only changed front sprocket and chain on mine as teeth on rear were not wore, that was 17000kms ago. No regrets.

Don't you have to remove part of the rear suspension because the original chain doesn't have a removable link? I thought I read that in the Owner's Manual.

Much easier to grind the pins on one of the links than removing rear axle and spacers.

[oneyunguy]

That's what I'm gonna do. grind or cut with bolt cutters.

Cutting it with bolt cutters is not a half bad idea, probably gonna be a pain in the you know what to do, but not a bad idea at all.

You can also buy a tool to press a link on there, if you are wary of having that master link on it.

I know that I need a 520 pitch. How many links?

soooo, how many chain links?

And also, is the part number for the replacement 16 tooth front sprocket still 27511-37200? I looked that up on BikeBandit and looked at what machines it fit, and the GZ250 wasn't there. Course that don't really mean much I guess. Just want to be sure before buying.

That is the proper number for 16- tooth sprocket.As for number of links I dont know,just count links on old chain.It is the same length for both sprockets.

[bonehead]

IIRC the # of links for the chain is 110.

That's because the 16T is STOCK on some other bikes but not the GZ.

Sprocket is listed for G.S 500 I believe.Bikebandit has different numbers try these:#A527D576 or #17866.
