Early model pump design and performance
I was just wondering what kind of performance drawbacks I will experience with my 90 model 650 lx, and 91 model 650 vxr. They both have what looks to be a dual blade intake grate similar in style to the old school Pro-tech. They both also have stainless impeller upgrades(not sure of pitch).
I was just curious about the top speed capability of these old pumps. And maybe any possitive aspects of the super light weight lx. I don't want to race anyone, just want a ski that is fun and fast for its year.
Any specific info on these pumps would be greatly appreciated.
