Hey all, Thanks for all the info, and help. I've got about 125 miles on the bike now and am very happy so far. I'ts fun to take a ride on the KDX 200(2001 snorkle removed FMF pipe and silenced, jetted) and the 1995 KTM440. I get off the KDX and think,where the heck did the power go? Then I,ll get off the 440 and think,what's with the on off switch power band. The Gas-Gas is a great bike, nice power spread and delivery, compared to the other two. And also nimble like the KDX, but stable like the KTM. The weather turned a little colder latley, from the 70's to the 50's. Last time out it sounded like a rattle, tock,tock,tock, when gassing it from quarter throttle. Would it be octane,jetting ect? I'm not the mcguiverist.
