I, just as others, hate to see someones sled burn down, or in Doos case GRENADE!! I own a shop and repair all makes and models of sleds, atvs, etc. etc. I have done several polaris 800 cranks, but usually you do a crank, maybe a cylinder, generally one piston and probably the head, and you can generally plan on around 2500 to 3k miles. Now the doo 800 on the other hand is a bomb waiting to go off! When it does, plan on buying a new motor, cause it explodes! I am a hawk dealer, and when they put the 800 in I was excited for the power increase over the 600, but always worried if I would be towed out that day. Well my new hawk in 07 lasted 20 minutes, brp took a month and a half to except there problem, that we have seen since 01. They told Boivin that they don't have problems with there 800 motors. Boivin didn't want to replace it for me. I bought my own motor from a local doo dealer, and it took a month and a half to get reimbursed from Boivin for it. Bull$hit if you ask me. Then today, one year since I blew the last motor, I take my hawk out for the first time this year, and got 30 min. out of the pos, and blows a hole thru the block!! I can't wait for my new 08 dragon 700 motor to get here, it should be here any day. Glad I planned ahead, won't have the long down time again. My experience has shown me that if you take all the brands, and ride them for 3 yrs, you will put less money into a polaris than any other. The parts are less expensive also! New ride this year same old 07 Hawk with 144, powered by 08 dragon 700 efi!! I am stoked, same rated HP, but ten times more reliable. PERIOD. Sorry for the epilogue, but when the 07 doo motor came out I asked the doo reps if they were going to blow up too, and they told me no. I asked will you gaurantee they won't, he said no! I won't ever by a SKI DOON'T
