cold weather pilot jetting question. need to know asap.

[sbjones73]

ok. i have upped my main several for the cold weather.

i would like to know if upping my pilot jet is also needed when going into 50-60 degree colder weather. i have a pj 34 carb in my 84 250r.

my last ice race i had to go to a 168 main from a 150 it was like 4 degree's outside with a windchill of like -20. my trike seemed to really start breaking up on the lower end like when off idle and transitioning to half and full throttle. i did go up 1 one the pliot froma 48 to a 50, but need to know if a 52 or 54 is needed during colder weather. or do i need to just raise my needle richer?

thanks!!!!!!!!

try the needle first then if that dont work re- set your needle and re jet

For colder riding, you should fatten up all 3 circuits in the carb. (windchill has no effect on machines)
