yeah it works
I have had many cats, turbo m's, big bore m's, lightweight mildy modded m's and I switched to doo for the first ride this year. lightweighted and mild motor mods, clutching dialed in. I had 3 days on the doo and was quite impressed, then a mishap ended the doo days. I picked up an 2010 M8 LE 153" with the insurance money, best thing I have ever done. noticable better than modded xp's with lighther riders on them. pulled up to a small chute with about 6 different m's and 6 different xps in 2 different groups all were gettting about 3/4's the way out the top on the 2 chutes in this bowl. It took me 2-3 pulls on each shoot but I was able to get out the top of both, that stirred up a couple of guys egos in the other groups and they began pulling the 2 chutes again, not one made it out. Don't take this as bragging, the chutes were very mild in my opinion, but with the fresh snow on them made them slightly difficult to turn enough track speed to pull the tops. The 2 1200 cats in my group were able to pull them after I put the track over, on a side note. This has been the most fun I have had on a stock snowmobile in a long time. Best part about it, no 6 hour nights working in the trailer tweaking and tuning, just ride. Very impressed and I get 30-50days a year in the hills and usually switch sleds every 15 days or so. I have this one for sale, but only because I want to change to a 162" if it werent for that I would keep the thing for a long while (at least one full season).
