Repair of engine case?
Is there any reasonable way to repair a crack in this area? It's not a hairline fracture, it's a break and complete separation of the aluminum. I will take a picture of the actual damage later today and upload it. Pretty sure this is a stupid question because the repair needs to be tight enough to hold oil pressure which sounds difficult.
The clutch cover is mangled and completely obliterated. Pretty sure the clutch basket took a hit but I don't believe anything is bent. I'm trying to figure out if it's worth repairing this bike or if it should go in a dumpster. I certainly have fond memories from the 35k miles that I got out of it before the crash. Both footpeg mounting brackets (on the frame) are bent along with both brackets themselves being broken. One handlebar is bent. The fairings are cracked and shattered and large pieces are missing. The rear tail section is mangled but I could stitch all of it back together with safety wire, not unlike my leg was stitched back together. Engine turns over but sounds like it has no compression which is odd. Exhaust pipe is mangled. The force of the impact broke the filaments in both headlight bulbs (I'm assuming -- otherwise there is something wrong electrically). I'll try to upload some more pictures so you guys can help me determine if this bike is beyond repair or not. Thanks for the help, this is actually a pretty depressing thread so I appreciate the words.

With care, it can most likely be welded and carefully finished flat so the cover seals. Whether it's worth doing or not depends on how much you have to pay the welder, and if you can finish the sealing surface flat, or have to pay someone in a machine shop to do it.
There is no particular oil pressure there, it's just oil at approximately atmospheric pressure. The pressurized oil is pumped to bearings, up to the cams, etc.. |

Not really a stressed part, I wonder if JB Weld would work.

I know of a case reeded H2 that used JB Weld to attach the reed boxes. The joints were nicely machined, but it didn't take long for the epoxy to fail. I'm afraid the heating and cooling would break the bond sooner than you'd hope. Of course if the repair is tiny, it might be OK.
