has anyone else thought how much the price of sledding is going to increase if everyone goes 4 stroke? seems you have to supercharge or turbo one to make it compete with the 2 strokes. have never seen ONE post where it states my stock 4 stroke was highmarking everyone. never once! with yami wanting over 10k for a 600 class sled, then the 5k plus to put on the turbo, your into a new sled at least 15k before you've even pulled the cord. another thing i never see the 4 strokers mention is the cost of rebuilding the motor. you could almost buy a 2 stroke sled for what your gonna pay! you can rebuild the top end on a 2 stroke for a few hundred dollars, and in a few hours. not the same on the 4 stroke. reliabitlity seems to be a selling point for the 4 stroke, but put the turbo on it and i see plenty of posts of rods, cranks going out. seems the reliabilty factor goes when the boost goes on. or do you have to put another 10 grand into carrilo rods and the such to make it half as reliable as it was before the boost? i have a good old 02 800 mountain cat with almost 10,000 miles and has never had ANY engine work done to it. almost 3,000 miles on my M8, no motor work.seems pretty reliable to me! not too many peeps willing to spend that kind of coin for a 2-4 month a year sport. let the games begin...
