2009n TXC 250 Jetting specs

Does anyone know of any jetting specs for a 09 TXC250 or some type of jetting chart? I am taking my winter jetting out and going with some type of spring setup. Guess I can just settle in the middle with whatever I have in there because the bike ran great. I know its going to be 50 on sunday soo my winter jetting needs to be updated.
Also,, the fuel screw that I put in............ that is only for the first 1/8 of the throttle right? i.e-- starting and idle. Right???

i had a 180/45 in there for winter. Decided to go to a 175/42 for this weekend.

should be fine dan,I usually go up on both one size for the winter,175/42 should work fine,good luck this weekend,and make some husky bucks !!!
