Comet 108 tuning

[gabbett1]

Some info for you on the spring. Original number 90501-551L9-00. Blue-silver-blue.
Preload 35 kg =77lbs.
Full shift out 101kg =202lbs.
Spring rate 2.00kg =112lbs.
Length long.

That seems really low for the full shift force. I found a chart that shows exactly what you've listed here. Says preload is 35 kg and total force is 101 kg. Interestingly, (although probably not what you should do) if you add 101 and 35 to get 136 kg and convert that to lbs, it comes to 299 lbs. Which would be about the same as what I was running.

What does the spring rate mean and how does it play into the overall rating of the spring?

The spring rate is kind of strange. It depends on the wire dia. number of coils. overall length. The spring rate can be all over the place going up the scale on a spring chart.

The best tuning info is the lbs of force at given height. Heights are generally spec with spring cover installed 2.5" and 1.25" with polaris springs. At engagement and at full shift out in inches and lbs force.
