I'm headed to cook city, Montana in January (elevation 10k-12k)and I need suggestions on what primary clutch weights to run and what primary spring to run, it's a 2012 pro rmk 800 155", I was told the secondary was fine stock, Thanks for any info!
Most of the riding in Cooke is 8-10k ft. Both of the stock springs work fine, 10-58 or 10-60 weights would work. If the stock primary spring is a couple years old I would install a new one while you have it apart.
Ok thanks for the info, I did notice the primary spring is black with a green stripe on it and from what I can tell it's supposed to be black no stripe (140/330), I'm the second owner and the guy before me said he did some clutch work to it so I'm going to order a new one.
