The pilot jet dosn't stop feeding fuel
just because the main jet starts to work
it feeds fuel though the whole rev range..
It's the combined size of both jets at higher RPMs....

cold climate... large pilot/small main , easyer
starting / warm up..
Hot climate.... small pilot/large main...
Or anywhere in between...

my bikes prob a little bit rich on the bottom end..
the US TTR250 & my NZ one have diffrent jet combinations..
