spawtydawg Posted September 2, 2019 Report Share Posted September 2, 2019 Hi everyone. Is it possible to convert a 200 pro into a 240 and vice versa? Are the bottom ends of the engine the same, i.e. gearbox ratios, crank, con rod etc? Would the barrels be a straight swap, and would you need to change the exhaust and carb? I know all the pro model frames are the same and I'm curious to find out if it's possible. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
jonboy883 Posted September 3, 2019 Report Share Posted September 3, 2019 As far as I was aware, the 200pro had a 125 gearbox with the 156 barrel. Im not sure the 125 gearbox would take the extra torque generated by the 212cc barrel of the 240pro.! I do know they were not the same gearbox on the both models.

mattylad Posted September 4, 2019 Report Share Posted September 4, 2019 Is the stroke the same on both engines, possibly not in which case not possible. Quote Link to comment Share on other sites More sharing options...
spawtydawg Posted September 5, 2019 Author Report Share Posted September 5, 2019 Thanks for the replies. I have done a bit of research and now know that the conrods are different and the stroke is longer, which would indicate that the crankshaft is different also, although from what I've been told the gearboxes are the same. So I suppose it is possible but would involve a lot of work. Quote Link to comment Share on other sites More sharing options...
