should i change m?

[ragincajun]

hey guys im goin to racin in some grass drags this weekend and i was wondering if i should jet up one size? the races are only about 1500ft lower than where i ride and i have ridden it lower and checked the plugs and they looked good but it was about 25* out then. they are only 500 foot races so should i change them or would they be fine for 500' races? thanks

cool. thanks alot!

Maybe check plugs after first pass and see (or after practice pass). Takes no time to do and that will be your true answer. 500 ft is a short race though so not like you're going to be holding it open for a long time.

the DPM will honestly take care of it enough, i rode in 100 degree weather with the same jets and didnt get any issues, cuz you really cant hold it open to long in the fields. 500 feet for your sled is like high single digit seconds, which is to short to burn er' down, like said above tho, make the first pass, and if there scary change em, but i doubt they will be
for saftey, when your done the run, hit your choke to soak it in fuel and cool it down.

no DPM. ill check the plugs after the first pass. and should i drain the old gas. i put stabil in last spring so should i drain it and out fresh gas in? i dont want to make my first pass with a crappy running sled
