750 Twin Tach Seal/O-ring/Gasket
04 Dec 2005 12:21
I have questions in regard to
this thread from the archive
(perhaps directed to steell):
When I bought each of my twins, they had no tach cables. I have long since installed a tach cable on my "runner", but it has always leaked a little oil.
Is the item # 92065-103 (GASKET,TACHOMETER GER) a pressed-in item like the oil seal itself, or is it loose?
I seem not to have it and I'm pretty sure it would solve my leak. Where's a good place to get one? Can I just use an o-ring instead?
Thanks in advance...

I have a couple of full gasket sets, along with three top end gasket sets, and that seal is not included in any of them 
The seal fits around the stem, and inside the housing, it comes out pretty easy with something like a dental pick, but unfortunately I have been unable to find the seals anywhere. I ended up using an o-ring that was a fairly tight fit around the stem and inside the housing (with the seal still in place), and it worked, no more oil leaks. I don't recall what size the o-ring was, I just went through my collection until I found one that fit.
Just so everyone knows what we are talking about

Thanks for the helpful reply.
Just for grins, I ordered one from BikeBandit.com for $2.40 + $4 Shipping. If it turns out to be just a rubber o-ring, well, then I'll buy one at the hardware store for my second bike.
I can't wait to be free of oil drip-drip-dripping on my exhaust header! All this time I thought it was the inner seal...
By the way, the part I'm describing is #6 in that picture you posted...

I think you should order a #7 92050-075 Oil seal also, it's a flat rubber washer and I think that is probably the main cause of the leak. I have 4 motors and that seal was bad in every one of them, that's why I had to find a thicker o-ring as the stock one just slowed down the leak.

You can buy both the seal, #92050-075, and the o-ring, #92065-103, as a seal kit from Z Power, Uk.
The price is £6.00.
