F650GS Dakar bigger bore?
 

Has anyone attempted to increase the cylinder size on an old F650GS?
I'm planning an engine build using an uprated con rod, bigger cylinder and a high compression piston. I've also been looking at a higher capacity injector to try and compensate for the increase in cc.
My ultimate goal is to find a programmable ecu so it can be tuned properly.

I'm a BMW tech. I've never seen it done but I know It has been as they have used that engine for racing YEARS ago.

I don't think there are any off the shelf kits but it IS possible if you're prepared to spend silly money.

Which is a bit of a pointless exercise as you can just buy the F800GS or a multitude of similar bikes.

This link may help a little.

Their prices are truly eye watering!!!


I can handle the nuts and bolts side of the build but its the reprogramming of the ecu that's causing me issues.


Do you know of an ecu that is programmable that could be made to fit???
