Re: RALEIGH GRUV anyone put a china engine on?
I'm thinking the area right where the carb would mount.
Also, there is a space at the bottom...if you are to mount the engine in the "V" it is going to sit low and may have interference with the sprocket.
You need around 12" from the crank to the bottom of the top (horizontal) tube going verticle from the crank, if I'm making sense.
Somewhere on this site is a diagram with the minimum measurements for the china in-frame engine.
