Disabling the TORS should only be done TEMPORARILY and only long enough to get it fixed.
A TORS activation/failure is usually related to one of two things; ice in the throttle lever (use alcohol to clear out ice), or being poorly adjusted. Regarding having ICE in the throttle lever, the main thing that causes throttles to stick (requiring TORS) is ice. If ICE causes your TORS to act up, you should NOT disable it, you should CLEAN the ice out.
If TORS is to be disabled permanently, it MUST be replaced with some other safety mechanism, like a tether switch, BUT THIS IS NOT IDEAL.
ALL sleds, regardless of brand, should be equipped with TORS as a matter of safety. If snowmobiles were subject to safety inspection, then this is one of the components that really should be tested. TORS is superior to all other engine kill safety mechanisms for this reason; it does NOT require you to THINK and it does NOT require you to JUMP OFF. TORS will activate even if you too stupid to hit the kill switch and going too fast to jump off.
More thought;
There is only ONE condition under which TORS should be disabled; broken switch. Rather than getting off and disabling it, you should FIX the problem - same effort is required.
Another thought;
If your TORS acts up, manual manipulation of the throttle lever will allow you to continue until a safe place to make an adjustment - the pivot on the throttle lever is in a SLOT. Force the pin into the forward/left end of the slot and TORS will deactivate.
