Yup. I do pretty much the same thing but I also have a jack to lift up the back end and run the track a little once the engine has warmed up.i always go and start mine up.Go back in and get dressed and about 5 to 10 min later its ready to go not sure if you have a heat guage or not but mine is about 1/4 of the way up after 5 min or sr if you have no heat guage you can reach under and feel the heat exchanger .
then i lift up the back of sled give it a couple good drops to loosen the ice build up.Then jump on and take it easy for about 5 min to get the belt warmed up. THEN LET ER RIP. [/b]
If I'm at home I start the sled, go get dressed, then head out and check the coolers...they have to be nice and warm...then I blurp the throttle a few times with the back end up on a stand and get the belt warmed up and the track rotating free.[/b]
