u would want to start around a 300 and work ur way down...check the plug, that will tell all

i had a 290 in mine last year, with my f7 and a uni filter, pulled very hard, but my plug color was alittle light, so i got the next size my dealer had, a 320, ran it good and hard all summer, but was prolly a little "safely" rich
