what did you end up for jetting with the pwk?
my friend has a 03 cr250 and hes thinking of chucking the tmx
did it fix the jetting changing for no reason?
thanks
the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.

Still has a slight bog from low rpm when you crack it WFO. Some say this is due to too large squish, others say if you run a 48 or 50 it should fix it. Its a bit rich down low on the 45 so I think they are just masking the squish issue with a too rich pilot. We will see...
