A few years ago we put up a short post about a fellow who made his own 694cc V8 engine with a homemade crankcase and his own crossplane crankshaft. Top ends come courtesy of engines from a Honda CB350F. The engine ran and sounded pretty sweet, but there was no information on it that I could find.

A quick run through the eBay listings this morning and something catches my eye, and sure enough, there’s the little V8. It’s mounted in a 1979 BMW R650 frame and runs through the BMW transmission. The engine has 8 Mikuni carbs and Petronics ignition with mechanical advance.

Dennis Franz is the man behind this little jewel, but it looks like the engine needs a bit of work and the bike would benefit from a little cleanup. According to Dennis, it shouldn’t be too hard to get things back shipshape and if someone bought this he’d have one beautiful conversation piece at bike night. Not bad for a little garage project. Check it out!
