Thanks for your help regarding location and alteration of throttle stop on my 00wr400. I successfully completed the project in about an hour but have not had a chance to test it. This bike is brand new, approx. 20 mins of riding, but I could tell I needed more juice. Its been raining here (Dallas/ Ft. Worth, Tx.)for the past three weeks and I cant sleep at night. When I get a chance to ride, should I refrain from full throttle for the first couple of hours? Thanks again.
