Hi Rusty;

Sorry for the long delay in getting this back to you, but I was hoping to have time to go down to one of the snowmobile shops and get you prices on new & used primary & secondary pulleys as well as the weights.I've just been too busy at school and when I'm home on the weekend I just haven't had time. I was going to remove the pulleys to weigh them, but the front pulley requires a special bolt to pull them which I used to have, but apparently I loaned it out and I don't know who has it. So I've attached a few pictures of the 2 pulleys on a sled to give you an idea. From memory, I'm going to guess that the combined weight would be approx 15 lbs. The new cost should be approx $1000CAD, but used I could probably find the pair used for a few hundred bucks or less. Sorry this isn't more accurate, but if from the pics you decide that you're still interested I will get precise info when I finish school this year. FWIW, I think this should work well, however they are no secret so I'd expect that somebody must have tried it already and we haven't seen any around yet soo....
