you can't compare a multi cylindered 2 stroke to a single cylindered 4 stroke when it comes to pull starting. I had a Suzuki 250 quad and it was hard to pull, you really had to give it a good swing, using your upper body weight and hold on tight to the handle or you would kill your hand whereas I can easily pull my 3 cylindered 600cc sled engine sitting down on the sled with one hand.

 

Two strokes take less effort than a 4 stroke of similar displacement. I base that on the fact that you are not also having to spin over timing chain/gears, valves, cam, etc. Also, you tend to 'feel' the compression more in a 4 stroke. Also, some of the big snowmobiles (800 and 900s) are very tough to yank.

 

the bomba you can buy it as an accessory? I don't think Polaris Lets you do that. I'm a strong believer if I don't have it I'm going to need it!
