    Ok so I have been wondering this. Has anyone tried to make the 690 enduro motor carburator? It seem as if the FI from the earlier models is very problematic and the solution would be to scrap it throw on a carb and party. In theory this sounds great but practical I'm not sure if easy. What would you need to do.

    Very easy, just buy all the 690 rally replica parts and you're done. Nothing easier than that.

    I have done it (there is a thread on it somewhere) and its not as straightforward as crankshaft suggests. The rally frame is different so the rallye airbox will not fit on an enduro You have to mod the enduro air box to fit the carb inlet and build a inlet tube. If you use the stock rotor, then you can use an ignitech ignition system, if you use the rallye you need the rotor to go with it. You can get tank plates from ktm to convert the stock tank.
    My bike got nicked, but if i did it again I would build a new air box from carbon fibre rather than bodging the old one.
