Gearing charts don't use HP or Torque ratings. They convert the engine RPM to track RPM and then to velocity through ratios of your clutches, sprockets and drivers.

Now, go learn how to use google

Don't worry about that google b.s , coming here and asking is what the site is for. . . Not that I have much of an input on this subject, as I don't have enough knowledge on technical clutching questions :)

Wow, did he get up on the wrong side of the bed? ^^^And you are correct, this is the place to go to ask questions. The OP is not one who continually asks stupid questions.

I have wondered the same thing myself after seeing a partial chart. Just never got back to it.

Ok thanks I thought they used horsepower. I guess I shoulda used google first, but I didn't know if someone just had it in their media gallery or something.

^^^The number of teeth on the drive cogs (the driveshaft is the one that drives the track, under the tunnel)

You should be able to look up a parts fiche and count the number of teeth if you look up your sled at www.babbittsonline.com
