Cuz a kdx is a swine and a KTM has no linky.JK!76GMC1500 said:Why not just buy a KDX 200 or an EX/C 200?

blackduc98 said:I would not want to build my own con rod or piston, but I would be willing to fab my own cylinder. You can find a bunch of info on DIY aluminum casting. You should be able to do rough machining of the cylinder, and then send it to USChrome for precision bore and Nikasil plate job to fit your piston, which will cost you roughly $200. You can start with a head from something like a KDX200. I would seriously look into building an ECU-controlled exhaust power valve and ignition. Megasquirt DIY ECU is a good base to start from. Since you'll be making your own cylinder and ECU, you might as well make provisions for direct fuel injection, but I'd get it running with a carb first. You might even investigate ECU-controlled solenoids that dynamically alter parameters of transfer ports in the same spirit as the exhaust power valve. Best of luck with your project.

SpeedyManiac said:My main problem with the KDX engine is that it's not a great performer unless it gets some major modifications. The idea is to make a lightweight RACER. Sorry, the KDX engine is just not up to snuff IMHO.
