Tach drive 84 RZ350

Somehow not sure how the tach drive shaft on my new to me RZ project has a badly bent tach drive shaft the part where the cable goes in. I need one. I do pay pal if that is OK.

PO hammered it in when the gears weren't lined up?

Why not another KOSO for this project?

When I get a minute I'll search my parts inventory Tim.

I am gonna go with a Koso. But I thought it might be better to have something in the hole than nothing. Thanks Ken!

I haven't looked yet.

How about this and be like a banshee?

A cheap option just install the plastic part and cap it with a brass fitting. I did that on one bike. Or you could use a plastic cap and paint it black.

Let me know if you still need the gear. I found some pics of my cap off situation. I used an o-ring under the brass part.

In retrospect I am not not gonna fool with it since I am not going to use a mechanical tach. I love your solution. I used a big rubber cap on my other RZ. Thank you Ken for taking your time to look for me.
