Changing front sprocket

ATLRIDER · April 11, 2012, 08:29:15 PM

Hey guys,

Any known issues using a front sprocket from an older 93' on an o6'. The newer sprocket has a shoulder built into it. Reason is I've got a 15 tooth sprocket I'd like to use off the 93'.

Thanks for any feedback.

You still in Atlanta?

I can't remember if it's older ones work on newer ones or the other way around...gsJack should know. He was the one talking about it.

Yes, Lawrenceville actually.

I'll shoot GSJack a PM.

Thanks

newer ones with the shoulder DO NOT work on the ones from 93 and older.

there simply isnt enough room for it.
tried putting my 15T sprocket from my 94 onto my new 89 engine and it wouldnt fit. (prior to knowing about the shoulder change from 94 on)

oddly tho, my stock 16T 94 sprocket didnt have a shoulder and fit fine on the 89 thankfully.

dont see it being an issue using older on the newer.

unless the extra room from the lack of a shoulder would cause a problem.

I don't think it'll be an issue either. Thinking the rear sprocket will keep it aligned.

Well, you're officially the closest person to me now. We should go riding sometime

Copied from a recent post of mine:

I ran three Sprocket Specialists 15T front sprockets for over 43k miles on my 97 GS. Was getting DID chains from Chaparral and they carried the SS sprockets back then and SS supplied the same hubless sprocket for all GS500 bikes. I called SS and they said that the hubless sprocket would follow the rear one located thru the chain. I had no problem with them and every time I opened the front sprocket housing I found the SS hubless sprocket running right next to the retaining ring with the extra space behind. BUT, first replacement sprocket I put on my 02 GS was run all winter once after a tire change with the rear wheel a bit out of line and that sprocket became quite wobbly on the shaft. Fortunately the wear was in the sprocket bore and the shaft spline was OK but I have run only sprockets with a hub on my 02 since. That's why I said it was OK as long as the rear wheel was properly aligned in post above. I'd still run a hubless sprocket if I had too in a pinch but I'd watch the wheel alignment with it. Your bike, your choice.

Yeah, I think it should be fine as long as the rear wheel is properly aligned. Thank for the input.

Sounds like a great idea except I'm gonna be selling my GS and this is the last bike I have. Had 2 other GS's and an FZ1. Selling to fund another venture. Will be buying another bike as soon as I possibly can and will definetely give you a shout out.

I see you've got one of yours for sale on Craigslist. That's a great looking bike.

...well, I'd consider why the shoulder was added. It spreads the load on the shaft over a larger area, so you don't wear out the shaft splines - or at least not as fast.

My 91 has wear on the splines - it's not catastrophic yet, but when it is, the economics are something like "braze on the last front sprocket your bike will ever have" because replacing the shaft is more work (labor, time, money) than the motor is worth. The wear on the sprocket was much worse, and keeping it well greased (the spline/sprocket interface, which is often dry as a bone while the chain is drooling excess lube) may slow things down.

If you throw bikes away every 10,000 miles, this may not be a concern for you.
