Does anyone know if it is possible to fit a 1987 K75 engine/trans to a 1985 K100 frame?Seems like it would bolt right up.

They put big block chevies in motorcycles, so anything is possible. I don't have a K100 to look at, only my K75 so I am trying to visualize what it may take. The rear of the engine and transmission should bolt right in and correctly position the engine. At this point , you could possibly use flat iron and make an extension of the downtubes that you could bolt to the downtube and to the engine. The big problems are going to be all the little things. If the radiator is left in the original position, the hoses are not going to reach. You will need the airbox for the 75 as well as the ignition system with coils. It could be an interesting project. Keep us posted if you tackle it.
