I will be pulling a couple of shifts at the hardware store this weekend so nothing will happen in the shop until sometime next week. Given that, I put in a little shop OT today.
Re-installed most of the stuff I had removed and it all went back together as expected. Always good.
The motor had been converted to round-slide Mikuni’s, which also required the addition of a fuel pump. While I commend whoever did the carb conversion, I’m not giving them any style points for the fuel pump install, which consisted of zip-tying it to the coolant hose.
I decided the cleanest approach for the fuel pump was to bolt a piece of aluminum flat bar between the motor mount bolts and mount the pump to the bar. Not rocket science but it beats a zip tie.]
I suppose it’s easy to consider Chaparral’s use of tunnel cooling as an obvious thing, but this sled rolled off the assembly line 52 years ago, before most manufacturers pushed out a production liquid cooled sled and long before it became a popular method for cooling mountain sleds. This was new territory for sled design.
Chaparral’s approach on the SSX was to fasten the cooling tubes to the top of the tunnel but cut out sections of tunnel which allowed the heat dissipating fins on the bottom of the tubes to extend into the tunnel and be exposed to the snow.
