I am now living down in alberta and riding in deep snow is becoming more of a possibility for me and buying a new mountain sled is out of the question. Therefore i am interested in putting a 136 track on my 93 sport, but im affraid it may not not have much power since its only a 440 fan. But i figure if those old sks 440s can spin a 133 than i shouldn't be too bad. So...does anyone have a any suggestions as far as gearing/clutching setups go? And how can i sqeeze the most out of my lil 440? Thanks.
