have pink spring, rooster weights. Want to be around 8300 rpm... have 42/48 helix with silber secondary spring, stock gears, 2014 pro 800 rmk external waste gate. I was also curious if a gram of weight loss still equals about 150 rpm increase with these weights?
So I ran 72 grams today which gave me 8000. I just pulled 1 red screw at the base and it ran so good I am just leaving it until I get home. I forgot to weigh the other screws and the colors didn't match according to the sheet. But 70 grams should put me right at 8300. Thanks for the replies
