If not allredy taught of, you should weld on some supports for the internal oil lines while the frame is still open.
Those V-twin vibrations allways find the weak-spots.

Awesome project btw!

I hope I'm wrong. It it looks like the motor is going to tear itself out of that frame. The design looks pretty weak. It doesn't appear that you're adding any more supports. If not, I think your going to have some problems.

I imagine your making a swingarm also. I'm sure that's going to look good.

I was thinking along those lines also. Seems like nearly half the weight of the engine is hanging off the front cylinder head. Will the case and front cylinder studs live when you add the operating dynamics? I’d like to see some additional support to the front of the case from the front support bracket.

Buell made tens of thousands of bike that had the motor hanging from the steering neck. So I don't think that's a problem per se'.

Torsional strength would be my bigger concern. Torsional loads on Buells between the engine/swingarm/rear wheel assembly and the frame/front wheel assembly are transmitted at multiple points, and the frame is designed to be torsionally stiff.

The OP never said he would race or daily this bike. There are more than plenty of custom creations out there which look beautiful and run but otherwise shouldn't have any business on the road. Im just glad to see someone building something rather than assembling something. At very least he didn't buy it.

Bet there's a bottom section for that frame back-bone, incorporating a top engine-mount, making chips fly on an CNC as I type...

I couldn't agree more. Didn't mean to sound critical. I think the whole project is cool as hell. I'm impressed with his mastery of cad/cam and cnc, too. I dabble in that stuff myself, and it's obvious to me that he's pretty damn good at it.

Bit Pusher (RIP) did a similar project; the engine stud was change with bigger bolt instead of stud I believe. He rode that bike pretty hard without bending the engine.

Sorry for your loss.
