I swapped my pilot jet to a #48, and 1 3/4 turns out on the screw, and wow, what a big improvement on cold starting, warmup, and low speed snap!!! 2 kicks cold, and my bike lites right off, let the engine run for like 45 seconds, shut off the choke, and off I go! Bike runs excellent. 2 Kicks with the hot start lever and it starts right up hot also. I will probably end up going back to stock jetting in the hotter summer months, but for now my 450 runs perfect. I also bumped my main jet to a 162 while it's cool here in New England.

Heres a pic the day I brought it home:
