All our 03 revs were covered multiple times. Almost every grass drag we went to we would need new rings after the race, and everytime doo supplied them. Ended up putting wisecos for trail riding to avoid having to change them. Tomahawk sports center in tomahawk is as quality of dealer as there is out there for doo and is prolly the difference in covered or not. We have never had doo leave us like some mentioned. My bros 05 mach, crank went out on lake our cabin is on, totally replaced engine for 0 dollars out of warranty. We ride with a good 15-20+ people in group, i cannot remember the last time someone was towed, back in 90's. All doo's. Preventetive maintance, warming up sleds thoroughly, proper jetting for carbed sleds go a long ways.
Yep sports center is excellent...if I rode ski-doos...I will be buying my sleds there....03 was covered by sports center...99 was not...not their fault....don't blame them a bit for it....it was very frustrating at the time...had little fench guy screaming at me on the phone...lol
