My 03 Canadian WR450 has the YZ exhaust cam, fmf q, and all the mods, can anyone recommend the best jetting setup or should I consider the jd kit? I do have to twist the throttle a bunch in the summer to get it to fire so I'm already considering a larger starter jet. Cold weather starting is terrible so I'm hoping to improve on that, otherwise I'm happy with the performance so far. I will be riding on a local river this winter so maybe I should consider a couple on the main?? Should I just bump up the starter jet and the main and leave the rest alone. Thanx.
