Realistically a 1 3/4" paddle is as large as you can run on a stock 03 rev with the 9 tooth drivers that come with it. I did run a 2" on mine for one season (yea you are not suppose to be able to, but I did as I have a PLP tunnel extension with drop brackets (more clearance to the top of the tunnel. The lugs did hit on occasion on decells when the track would hump up on top... I subsequently put a ZX (04/07 rev) chain case on to get the necessary clearance to run the 2 inch with out rubbing. An 1 and 3/4" paddle should fit stock though. And yes, I would get rail extensions for a 136" from Mountain Machines Performance or Tracks USA that pick up the the sliders and go that way. Lots of us have done it.tangogawd said:
I have 136" set up for Michigan off trail riding and a 144" set up for mountain riding.
I don't believe your gade skid will fit under her sled.. with out moving the rear arm. Or the rear bracket on the tunnel.... 2005 skids have a longer front arm (brackets welled to the arm) that lengthens them about 1 3/4 or 1 1/2, I don't remember the exact number off the top of my head. And they have a different spacing between the bolts that mount the skids... so to put your skid under the 03, you would have to move the rear brackets on the tunnel or change where the rear arm is located on the rails.. and that would screw up the rest of the skid geometry most likely. Easier to put rail extension on her sled..
