That tank looks sweet, would make a nice gas tank too. What's taken so long to get that bike together? You short on free time. I keep checking for progress and don't see much.

Beautiful notch, too bad you can't just turn the head like an HT, but then it would be an HT, lol

When its seen where I am going with the seat pan and the riggings below the seat and seat post it will be far from a weak point.

A few more pix. Under consideration is a king and queen style seat built onto the frame. Deiseldave this is why I have little concern for the spark plug notch out.
Still sorting a post to connect the top and bottom of the back of the frame as the stock seat post has been removed.

maybe weld a piece of plate on the top to reinforce the frame the seat should hide it. i woulnd trust it if you hit a nice size pot hole it might break

Old, Fat, and still faster than you
I'd strongly suggest you DO install a tube connecting the top rail to the bottom. This will greatly improve frame strength as it ties the "corners" together for triangulation.
This bike is far too pretty and powerful to take any chance of frame failure.

Yikes, brother. I wouldn't trust welding a bracket to thin, stamped metal to save my life. Sory, but those springer forks are almost all made out of stamped sheetmetal. I'd be afraid of braking my fork in half at 30 or 40mph. Or of the welded bracket breaking off. I'm running hydraulic motorcycle forks. They've got a tab similar to the one you've welded on to your springer fork, but its on a much larger diameter steel tube (not stamped sheetmetal). Unfortunately, the Worksman hub is not wide enough to reach the tab on the fork. I made a bolt-on bracket out of a motorcycle chain guard. One end of the bracket is bolted to the hole in the brake arm, the other to a hole on the fork originally intended as a fender support. I don't run fenders, so that's not a problem. I realize that your brake only has one method of holding it in place, but I hope that weld never fails and your fork never breaks in half. I recommend finding some wider diameter forks of some kind, or at least springers made out of heavy steel. Not dissing you bro, just concerned is all.

I just realized something. With static gears on both crankshafts, pullstarting either engine will cause the other's crankshaft to turn. Is this good or bad? I know that with some engines, bump starting by putting force directly on the crankshaft puts extra load on the crank seal, and the crank seal will eventually blow from that pressure. So I'd watch out for that.
