Adding weight on M8

[avossler]

Just wondering if I add 1 gram of weight how much rpm will I lose? Running modded M8

run it and find out, look at the gauges. It will depend on your altitude too.

if the profile is the same...probably 100-150 rpm...if an adjustable you probably want to load it in the heel

What are you running in it now ? grams ? primary spring color ?

2009 M8 with 901 D&D big bore kit. This is what I was running primary titanium yellow/white and 75 gram weights, secondary D&D torsional kit with purple spring. I had to back the spring way off so I would not over rev but had no back shift. I added some 77 gram weights and had to tighten my primary all the up to get to desired rpm but still not there, it does pull way better though. What would you recommend, heavier secondary spring of lighter weights? Any help would be great
