I am looking at changing my primary spring but I dont understand the chart on the EPI site.I was told I should get the maroon because I got my clutch and spider milled this is what the chart list the maroon at 2 1/2" load-0.5 kg, 2 1/4" load-15.9 kg, 1 1/4" load-77.2 kg can some one explain this to me because I don't fully under stand it I think it means to compress the spring 1 1/4" it takes 77.2 grams of force is this right?

 

Look at this chart, it should be more helpful. Read the FAQ section if you don't understand what stall and shiftout are.

That link is for the V Force. Is the information the same for the Brute 750? Looking to get the most out of the belt drive that I can. Like to improve mid and top end. Any recomendations?
