was thinking of looking at the merits of a kdx250 engine into a xr250. great engine and the xr is a goodturning well braked bike. (84 model) down a bit on go and with some reliability issues.

any thoughts?

I would only be interested if the dx engine will fit within the xr frame parameters generally, not interested in a major cut and shut.

I think the xr engines where stressed members so you would have to attach the kdx lower frame cradle...now what where you saying about a major cut and shut?

now you mention it I think they were was a good idea for a while.....

still, would like to know what the dimensions of the XR mptor were...

84 XR250 = full cradle frame ,earlier models were stressed member though
