I geared down today to 22/38 with 8dn 20 in primary straight 47 helix red spring and I punched out the middle weights and put bolts wich weigh 5g, 80 degree twist and got 116mph on gps but only reving 8100 in low end then 7800 in mid and back to 8000rpm at the top end. Pulls alot better with that gear. I will trying to get the 8100 rpm in low end and 8500 rpm on top end. My low end is there I just have to get my mid up and top end up.
