I'm running with Turks setup 53/43 helix,grn spring at 60 as well I put on the inch and a quarter ripsaw. I added 4.5 in the stock weights because I was overreving. I found my RPMS were still a little high 8700-8900. It was the end of the year so I ran out of time to try other setups for the RPMS. The new season is coming and I'm going to put a 21t gear in. As a result im assuming that the RPMS will jump up even more with this combo Should I look at changing the weights or rollers in the primary to get the right setup?? Anybody have suggestions for me Thanks
