Hello all, just got me a 05 KX100 and I want monster low-end torque (I know, 2-stroke and low-end are mutually exclusive), so I called Eric Gorr thinking I would get the "we'll mill the bottom of the jug to lower the ports" that I read about so much, but instead he said that the hot ticket was a JMS aftermarket KIPS valve, saying it closes the exhaust port more, giving much more bottom-end. $150.00 and I send him my cylinder was the price. I did some research on the web and could not find one reference to this mod. Anybody heard of it? Is it the holy grail of 2-stroke bottom end?
