I am running the 755 (700) verision of the 866 (900) and it viberates a bit. but the torque is insane. I think Poo let it go because of vibration and the complicated exhaust/intake set up both off the front of the motor. We all know this sled was not ready to be released, but it can be made very user friendly with some SLP products and some knowledge of sleds. Mine runs fine and can find trees with the best. If you like to tinker/tune it is a sled for you. If you need to run to the dealer to change a belt forget it. Joe aka Wintertime, look forward to Island Park with you.

looking forward to island park with you too. lets just hope that i have the right sled ready to go out there i would hate to have to take the short track 600. I should hear tommarow night the outcome of my situation and as you said the engine can be great with the right set up most powerful motor i have ever ridden.

Hold together fantastic. some need water pump rebuilds on 700s. I loved my 2003 700 rmk. Side hilling machine. Liberty motors are bullet proof. The VES valves in the 03's some are aluminum (early yr.) need to replace with titanium. They like the gas. I can not blow up a sled even when I try at 11,500 ft. must be the oil? LOL actually i keep my sleds clutched to run about 200 RPM below max. so as not to blow it up. I stick around 7800 RPM tops on Poos. gives me room for error.

when you say water pump rebuild u mean belts or bearings?

coincidently my buddy Joe is having his crank rebuilt in chicago now for the 2nd time in 500 miles. I hope to pick it up for him this weekend. He is a great mechanic, but I sense some disappointment with him. Hopefully something can be pinpointed.

surprisingly it was because of a faulty rod bearing not the usual bearing to go on the 900's
