Chain Case Saver" (patent pending)


We now offer a "Race Plug and Go"
(patent pending)

It simply tells the computer that the sled is running at 110 degree's. No more having to let your sled cool down before another pass!
It is a big pain to get the temperature sender out so we made it easy to install, just unplug the temp senser from the harness, plug in the "Race Plug and Go" and your ready to race!!
We recommend that you install a aftermarket gauge so you can see what the true temp of the engine is...



"Plug and GO" Temperature Resistor (patent pending)

The "Plug and Go" just tells the computer that it is running 20 degree's cooler. The sleds that have the bar gauges run most of the time here on the flat lands run at 135 degree's (4 bars).. 104 degree's is 3 bars, 140 degree's is 5 bars. So you can see there is 18 degree's between 3 bars and 5 bars, with running temps at 135 degree's. It only leaves you with 4 degree's before timing retard.. The "Plug and Go" is just to prolong the pain of the dreaded timing retard.

It is hands down the edge over the sled without it!!! Lake racing, trail riding, extra 2000 feet wide open,, or an extra 1 or 2 passes.

This is nothing new at all, many race shops use them. It is just a big pain to get the temp sender out so we made it simple to install. We ran these on many sleds before we were ASKED! to start selling them. We find that they are nice to use with a gauge so you can see what the true temp is.. remembering that you are 1 bar warmer. And those who do not have gauges the light will come on with enough safety to warn you before engine damage occurs.
