58841418-429D-493B-927A-BEA0E45911C4.jpeg I am looking for the longest motor mount bolt.
Its the one on the bottom center of the engine.
It is for a 73 tx650. Its an m10x290mm.
These came in different lengths for different years.
290 mm is 11.417 inches long not including the head of the bolt.
 
You might try (of all places) "Runnings", in Monticello, Mn. If your store is anything like the one near me, you might be in business. Ours has a surprising (!) amount of (various grades) metric hardware. Zinc plated, cad plated, hard chromed, chromed, and stainless. If that doesn't work, try a piece of metric all-thread, cut to length, with stop nuts at either end. Good luck, and let us know how it turns out (we're nosy!).
 
Great tips! Sometimes you just have to think outside of the box. I did find an oem one on ebay but a $20 bolt is a bit of a last resort. I’m not working on a trailer queen. I will check out running’s on Monday.
 
I think if you wanted you could get a 3 foot stick of 3/8s all-thread and cut it to length.
 
I ended up going with the threaded rod. I am not super happy with it but it will do for now. I was torquing it down and it started to feel a bit spongy.
Runnings did have a lot of hardware but nothing long enough other than the threaded rod. Eventually I will find an oem bolt cheap but a few dollars for the rod and two nuts will be okay for the time being.
 
If shotgunjoe does not find one let me know and I'll see if there is one out in the barn with the parts from the 1972.

And as a side note there is a highstrenth allthread rod if you go to someplace like McMaster-Carr. Most normal hardware store allthread is very soft steel!

Standard Hardware store stuff is most likely 50,000 psi Tensile Strength where the good stuff is 150,000 psi!

Looked every place it should have been and a few it should not have been and at one point thought I had found it. Even took time to clean it up. Measured it and then realized it was 10 1/2 not close to 11 1/2.

Sorry, if I do stumble on it I'll try to find you posting. I have the frame and the crankcase that the bolt would have gone through so not sure why I don't have the bolt!
