1100/1150 engine cases. Interchangeable?

[dorkburger]

The reason i ask is this. A friend has an 82 1100e whose engine was disassembled due to a broken ring/cylinder damage. it was never fixed and has sat in varying forms of poor protection for 15+ years. The same friend also has remnants of an 85 1150es that was totaled in an accident 3 years ago. the bike ran well, but the cases were damaged in the wreck. Could the 1150 assembly be swapped into the 1100 case? Ive heard that it can, but wanted to check with the gurus here. My freind mentioned the other day about maybe rolling the 1100 out of the shed, and possibly doing something with it. If the cases can be swapped ,im thinking we may be able to put it together for relatively cheap.
Thanks for any info.

Yes it will; 1150 crank, cylinder,head and pistons with 1100 cases. Experts will come along to confirm.

Thanks Posplayr. i just searched Monmouth Cycles online parts fiche hoping to possibly check if case numbers match between mentioned years. no case numbers shown. Ill take your advise as hope, and put the question out there again....Thanks.

I think the only problem you may encounter is in the clutch and trans area. Be sure to use matching crank gear and clutch gear, the gears are different between the 1100 and 1150, I think. The trans should work fine if you check clearances and shim as necessary. Different cylinder studs between the 1100 and 1150, use the studs corresponding to the cylinder head.
