Yea i need the same thing but for an 07 kx250f....i think the stock on mine is 60 and the 450f maybe 70

this is wat i was thinking...if u time the squirt earlier, so that it barely hits the valve slide..that would mean u would need a longer duration...so i would think getting a smaller leak jet would be better b/c smaller leak jet leads longer squirt duration/volume. but also u dnt want alot of squirt b/c it would cause the mix to be too rich after the revs build up...

so really i dnt kno where to go either

Stock is a 70, you want a 55.

250f is 60....450f is 70

but would that apply to my 250f...especially here in NY...the summer's are usually 80+ and humid...altitude is around 131 m
