does anyone have the specs for a maxx performance blue primary spring I thought I had it written down but I don't

Thanks guys ;)!
 

hey Tony I just weighed my 8bu-00 again and this time on a better scale and they still come out at 50.1 grams and with that is empty with a 4.5 rivet in the tip it weighed 54.6 and with loaded with 3.1 in both holes it weighed 56.2 WTF!
 
50.1 EMPTY ? WOW. YOU HAVE A BUILD UP OF BELT DIRT OR GRIT ON THEM. 8BU-00 ARE 48.6 EMPTY. ANYWAYS I WOULD RUN THAT MAXX SPRING YOU HAVE WITH THE 8BU-00 SET AT 54.6. TRY A HELIX AROUND 50/38/39 ish. GREEEN SPRING AT AROUND 80 TWIST. 3:16 (yammie tony)
 
50.1g empty on 8bu-00 sounds right. that's what mine weigh. the yamaha weights weigh approx 1.3g-1.5g more than what yamaha states them to weigh. i think its the bushing that's to blame for that.
 
Thanks guys

Will be testing this after I get my primary rebuilt and cleaned. I have my secondary ready with 50/40 bender and Yamaha silver @ 70 next in line is a Dalton 50/38
