S-7 nozzle creating lean condition?

[QUOTE="MOLE111, post: 588559, member: 39629"] ok ok , what's up with the s-7 nozzle lately ? a year ago it was the hot ticket and now i'm starting to hear results like this and wonder if i should put the s9 back in . i just rejeted my 01 cr250 over the winter and havent ridden it yet , should i now be concerned that it will be too lean with the s-7 in there ? anyone having good success using the s-7 . i currently have the following set up : 40:1 , sea level , temps mid 70's pilot - 30 needle - stock 2nd position nozzle - s7 slide - stock main - 420 last summer i ran the 30 pilot , 400 main , needle 2nd clip with the stock s9 nozzle and slide and found the bike to load up easily down low and in trailing throttle situations which caused a noticeable loss of response when re-applying the throttle , and there was noticable spooge at the end of the day . i was hoping the s7 would cure this although i don't want to stick a piston . should i be concerned ? i ride mainly offroad and play on an mx track on the rare occasion .
