Hey guys,

Thought I'd ask to see if any of you knowledgeable wonders know whether the tacho drive from another GS (such as the 450) will fit my GS500? the tach drives look very similar and the one I bought last year in preparation for a time such as this is too long and has this weird collar halfway down which isn't helping.

Cheers guys

Not worry, query resolved

...

What did you find out?

The mandem on thegsresources forum confirmed the part number for me: 26431-45002

I used a combination of fowlersparts and partzilla to search. Fowlersparts is rubbish, they can't get most of the parts. 

Anyway, search on partzilla provided these versions of GS used that part in their motorcycles:

There's no guarantees that this list is accurate IMO but partzilla do seem to stock OEM Suzuki gear.

I've found a couple of gs450 tachometer drives on eBay. The non OEM replacement I bought off eBay last year in no way fits, so my advice is to avoid them. They're too long and my camshaft came this morning and the threads don't mesh either. 

Suzuki seems to be the king of re-using parts on multiple motorcycles.

Actually.... nobody really stocks the OEM parts they show online. Brake pads, clutch cables, etc, maybe. But a tach gear? Stuff like that is coming from Japan - so expect 2-3 weeks delivery.

I wouldn't buy from partzilla, the P+P would account for 67% of the price for me. I bought a used GS450 one instead.
