430 Puma Kit

Currently LED is working on a 430 Puma kit. This 430 Puma kit is for a Honda TRX 250R with an 85mm bore and 76mm stroke crank shaft. All though the Puma will make great power with out porting, on this cylinder we are doing  port work to improve transfer and exhaust port shapes. We are improving the scavenging to improve acceleration and increasing exhaust port area to increase peak horsepower. On this built we are using the oversize exhaust manifold. This engine will use on of our large volume drag pipes. The cases have also been machined to accommodate the Puma cylinder.

KTM 450XC Project

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.

BP MR9 fuel test, this test shows how important fuel is in the chart below. 

Here are some photos of the bike and the pipe. 

KTM Over Sized Valves

Yesterday at LED Performance we worked on a KTM 450XC 530 kit. We are installing over sized valves in this head and we are also replacing the intake valve seats.

Shop is Closed Tomorrow

Due to unexpected issues to shop will be closed tomorrow Saturday, March 19.
