What are running for drivers and gearing tooth counts there Tony?
Dave,
Polaris drivers 8 x 2.86. Found the shafts with drivers on e-bay for $75. Bought the 155 take off skids from Tri-city for $150 each. A steal. Running 18-45 gearing.
Eric,
They are running premix. The 550s have heat soak issues that cause an air bubble in the oil line. The PI bypass fix didn't resolve the problem.
Replaced the pto bearings with BRP isoflex sealed bearings. This mod should come right from PI.
Replaced the speedometers with tachometers. One has IceAge straight rails and one with Polaris tip up rails. The tip up rails are a better fit for this sled. Both have HPS cans. I narrowed stock RMK bars as much as possible for the kids. Gripper skis on both.
Tunnels are made from .080" so the kids could bang them around, and they have.
Would like to put the 02 440 Pro-X top end on one, 88 hp.
