Hey guys, would it rob any HP if I used a very stiff primary spring and lots of weight VS a weaker spring/less weight?? I mean for both rotational mass weight and Hp to move past the spring tension.
 

Thoeoretically, you'd put up the same et's and hp numbers. All that force working against eachother will have an effect on longevity though, mainly in the primary. I like a lighter set up for long lasting and ease of tuning on the trail. Try hand squeazing a HC spring!
 
I don't know how much of an effect this would have, but in theory adding more weight to the primary will slow dow you engines ability to build revs quickly. Slowing acceleration.
 
Adding more weight to the primary will make upshift quicker there bye making the sled accelerate faster. At least in western Canada they work that way.
 
But if you increase the spring pressure to counteract the weight, you are essentially just adding more weight to the rotation.
 
And yes, you can reach a point where the weights are so heavy, it takes more power to just swing them and change engine speed. I think the RX1 leans that way, a lighter overall set up is more responsive.
