Hey guys, I have a low hour 01 cr250 that I just picked up (less then 30 hours on bike) and everything original. Only thing changed so far is a set of protapers and a pro circuit spark arrestor. It has the stock jetting (420 main) (35 pilot). I just purchased the jd kit ( I have done alot of jetting and just figured this would save time since I have enough work already lol) But I am curious between this and just saying to heck with it and going with the airstriker carb instead. Jd said if the jetting did not work out that I could send it back and go to the airstriker. What are your guys thoughts about the TMX with the jet kit? was there a marked improvement? The bike starts and runs great and idles nice but loads up often. I am looking to gain some crispness and to not have to be wrapping it out all the time just to keep it cleaned up. Also going to be adding reeds and a pipe soon also.
