Love the bike the motor mount looks good cool please let us know how well it works
Hi
Is that a 3 point engine mount?
Could you please tell us about the 3rd point?
I was thinking about two metal clamps secured around rubber donuts in the mounting locations, and the engine bolted to the clamps
Will build my prototype and post pics
Peace
I took a piece of 1/4 inch black pipe, ran it through frame and mig welded it in place on both ends.This made a solid mount with no stress on frame.Since the 1/4 pipe is 1/4 id the bolt fits great.Harley and honda do this on every frame they make and i have never seen one break yet.I know most of you dont have welders but it is worth the time to take it to a shop and get it done.you might want to drill the hole yourself and cut your pipe to fit and have it ready ,The more you do the less the welder will have cut and fit.Less time means less labor. HARLEYS DadI'm not a structural engineer, nor do I play one on TV. This has issues - IMHO.

While I like the bushing idea for vibration dampening, I think this sends at the very least some visually alerts off in my brain.
1) I don't think drilling through the down tube is ever a smart idea. Maybe if it was a hole alone it wouldn't be an issue but you've got a buzz saw on a single bolt throught the hole.
2) Is that another hole (smaller) perpendicular to the mount hole?
3) You have the dynamic mass almost at the center of the chord.
So I put this all together and it seems you have created a fatique point and are purposely reefing on it with engine movement![]()
I hope someone tells me I'm full of poo and you are safe.
