This bike is running a LED Performance KTM 530 kit.
When it first rolled into our shop it had a 530 kit with a 97mm 12.5 - 1 compression ratio, CP piston. The carburetor was bored to 43mm. It had a Motoworks slip on exhaust and a KTM 807 camshaft.
We modified stock header and built a megaphone exhaust system and muffler. We installed 31mm exhaust valves, 37mm intake valves and to accommodate the larger intake valves we installed oversized intake valve seats. We then ported the cylinder head to improve air flow and optimize velocity. To control the valve train we installed Kibblewhite valve springs and set valve seat pressures. We replaced the KTM cam shaft with a Web cam shaft and we continued to run the CP piston. We also built a sheet metal intake track with a K&N air filter attached.
The dyno chart shows the power gains of our kit by showing the power before and after.
