First year riding I did a Dan Adams clinic. I asked Dan how I should spec out a Pro if I snow checked one. He was adamant about 2 things. 163" track and e start. I pushed him on both issues as EVERYBODY else I was asking about sleds was recommending 154" track and pull start. Track is another thread but his reasons for e start were; weight diff was 20lbs which he was positive no one could feel on the Pro, with e start you will rarely let your sled idle which wastes gas, can foul plugs and contributes to overheating, at the end of a long day you might have started a sled from 20 to 30 or more times which is a big drain on energy, pulling starting a sled is hard on your neck, shoulder and back, pull starting a sled in a precarious place can be tough ETC. I am really glad I listened especially since I use lightweight batteries so the total weight penalty is less than 10lbs. I am a pretty burly guy and ALL my sleds are pull start now and I get a ton of crap for it but MAN DO I LOVE MY E START.
Think for yourself, little follower. "well if Dan says it, it must be true" get a life Matte
