What is the longest skid I could drop in an exciter reasonably. Would too long of a skid cause a significant loss of power or performance.
 

I probably wouldn't go longer than 144. Too long will make it work harder to turn the track but gearing can help bring that back.

So are yo saying I could go bigger like a 151 if regeared if so how much top end would I loose from regearing
 
Yes you could go 151 if you regear. How much top end you would lose depends on how much you change the gear ratio. If my math is correct, each tooth you drop on the top is approximately a 5.5% reduction in gear ratio. Now if that 5.5% correlates directly with top speed, I dont know. Im not a math whiz. If it does and your top speed is currently 91mph on the speedo and you drop down one tooth, your top speed would be 85.995 mph not accounting for the parasitic drag of the taller lugs fighting wind resistance as the track rotates.

if your considering taller lugs smaller drivers, driver size reduction is equal to re-gearing. about 11% reduction going from 9t to 8t drivers, even more if using 7t.

cant recall the stock driver tooth count on that sled, but you can easily count them. about a 1" track is all you can stuff in there with stock drivers and effectively move the snow through the tunnel and bulkhead.

that sled will easily pull a 151, but you run into issues with the coolant system getting a clean factory appearance due to the rear heat exchanger configuration being under the seat.

I was hoping you would chime in. Looks like the Exciter has 9 tooth drivers.

8t will effectively clear a 1 1/2" track and works well. the 7t can take taller lugs but the efficiency goes away due to the bending of the track. takes away power.

7t on the phazers worked well, didnt see the same results on the exciters.

Okay so basically I should drop 1 tooth if I want a taller lug. And a 151 will work fine also the exciter has a 15" track right if so could I use a skid from any sled that runs a 15" wide track.
 
you can also use your existing skid as they are similar in design to todays mountain sleds assuming yours has the torsion spring style.

you take part of the length equation by relocating your stock skid back and adding rail extensions to achieve desired length, within reason.

correct on the 15" and its a 2.52 pitch.
