Having got the motor of my Super nice and loose I can’t work out how it comes out complete. The book cheerfully says move it forward and lift it out but the flywheel fouls the frame at the back and the exhaust port at the front in spite of removing the decompressor assembly and the transfer ports. I have a comlplete rebuilt motor to go back in and don’t want to remove the barrel in order to fit it. Can anyone help please?
I seem to remember that I had this problem when rebuilding my Two Speed Sports. I had to remove the exhaust stub which fits into the exhaust port by carefully tapping it from side to side. After that the engine came out really simply.
The stub on the new motor was retained by a rivet, once that was drilled out it came out easily. The stub on the motor in situ was stuck so I took the barrel off. The new motor fitted easily and is now sitting in the frame. A pity the otherwise excellent Mr Kelly (technicalities) didn’t mention the stub in his article. So thanks Lewis for getting me out of a jam.
Dave, aren’t you referring to the 3-speed motors? My 2speed one lifts in and sits on the bottom frame rails rather than between them.
I think that is a Flyer answer to a Super question.
Taking out a Super type engine from a two-speeder frame is a bit of a chinese puzzle requiring patience if paint is not to be chipped but the route suggested – to remove manifolds and transfer ports and exhaust stub does make it possible. If memory serves well the engine needs to be lifted and moved rearward so that one cheek of the crankcase sits one side of the single down tube and the flywheel will be on the other. then turn sideways slightly to release it.
Good luck and stay calm…
Of course, you are right; I stand corrected! That procedure is for the Flier engine, I had mis remembered as they now say! I was thinking of the Kelly article which I hadn’t looked at for many years and assumed that it was all 2 speeder related. As Richard said, it’s a pity that the Kelly article didn’t mention the exhaust stub.
