Discontiued parts.

[Guest]

My GS850 G motor is in a garzillion pieces awaiting a decision on me to either source new gears for the transmission, or look locally here in Perth WA for used box and salvage the gear clusters out of a used bike.
Problem is after searching the web and Suzuki's sources some of these gears are no longer available.
I'm currently trying to source these transmission parts for a 1981 GS850 G shaft drive bike.
The microfiche numbers are as follows.
24250-45102 gear 5th drive
24231-45104 gear 3rd drive
24240-45100 gear 4 th drive
24310-45100 gear 1st driven
24341-45100 gear 4th driven
24331-49202 gear 3rd driven
24351-45104 AA discontinued part
24320-45102 gear 2nd driven
24141-45102 shaft outer counter.

The problem that has haunted me over a while is that the gear section where the shift tongue sits has worn, and this binds both the gear & tongue and stops the bike shifting up gears. The gears show signs of oil starvation on the main cluster with heat build up.
The complete motor has been stripped, and the dealer has offered to fix it for $1800, labour included. But this also means I have to try and source some of the reduntant gears.
Two things worry me, 1st is that if I source all new gears is that going to fix the problem and put strain on the old shaft parts.
2nd, if I use a used cluster in good condition does the problem just arise further down the track.
Any advice would be welcome.
Cheers.

GS850 transmissions are pretty much entirely trouble-free -- I'm pretty sure this is the first time I've even heard of a problem with a GS850 transmission.

So I wouldn't be afraid to simply replace your components with a good low-mileage set from another bike. If you want to be super-careful, perhaps new shift forks if they're available.

You will want to be double-check the part numbers because there are some slight differences in gearing across the years and models.

We've checked the numbers against the dealers microfiche, and we're pretty confident these are correct. But what has me puzzled is if they are so trouble free how come there's no more spares available. Some one must of bought up big on these parts at one time, maybe for competition bikes.
But it looks like the second hand parts will be the way to go, if I can't get new.

850 gears, while tough, aren't resistant to bone-headed abuse/non-use of the clutch. I suspect there are many high-mileage GS boxes that are scrapped because of simple wear and tear, especially when fell into the hands of less than careful owners, who abused them, and crucially, didn't bother changing oil every 2K. Every car/bike goes through that dip where they're still new enough to be attractive to dirtbags with the driving abilities and sympathies of an oran-utang, but not the necessary skill or ability to maintain them right.

There are dozens of cheap transmissions on ebay in the US. A Medium Flat Rate shipping box from USPS costs about $60.

For 1800, you can just go buy another really nice bike.
