I have a 08 nytro mtx with about 800 km on it it's only pulling about 8200 rpm in the hills. I'm running at 6000 to 8000 ft ,what would be a good setup?

I have the same problem, I was told go to a Green/Black spring on the primary amd lighten the weights on the end 2 grams, I have the spring on and did bring me up top 8400 rpm so obviously the weights are too heavy, I understand stock they have no rivets so how do you lighten them? going to take apart this weekend to get a better pictureof whats going on, would love to hear some recommendations.

if you have no rivets in the weights, all you really can do is increase the total force of the primary spring, to get the desired rpms.
look at what spring you currently have in there and start buying stiffer total force springs.
or you could grind the tip area on the back side of the weight. just make sure you have a good scale and match the weights.
if you have a service manual, it gives the total force ratings on the springs. adjust accordingly. ski
