i can help you on how to actually do it, im just not sure about the weight on suspension thing. i have seen it done both ways, and im not sure what or how polaris recommends it for you quad, although im sure soon, somebody with a TB can chime in and say. i think it is with no extra weight on the machine, but i could be wrong there.
how to do:
looking at the picture below, the first thing you need to do is loosen bolt #30 (2 of them) and nut #27. you shouldnt have to take the nut off of the bolt, just loosen it as far as you can.
now, looking at the pic below. see #13? that is your axle housing on the center of your drive axle. the bolts you just loosened up clamp around that lobe. you will notice on the housing, there is a large "nut" machined into the housing. you need to get a wrench big enough to fit that nut, and you use the wrench to turn the axle housing. you will notice, the axle sits off center in the housing, and the housing itself is basically a big lobe. to tighten the chain, you roll the lobe towards the front of the machine, the axle to the rear. to loosen the machine, do the opposite, roll the lobes to the rear, so the axle moves to the front of the machine. when you get the proper chain adjustmen, just tighten the two bolts back up, and your done.
did that make sense? and if nobody chimes in, you can try calling a dealer and asking the service manager about if the machine should be weighted or not, and what the play in the chain should be. good luck!

I bought my son an 2002 scrambler 90 and I can't get it to run right. It wouldn't accelerate at all at first. So I turned both these screws in all the way and backed them both out 1.5 turns. Quad started up and was idling at like 2k. I took turns and tried to adjust each screw individually to...
Hey can anyone tell me if there’s any special tools required to replace the silent chains in the transmission of a sportsman XP’s 1000 other than a clutch puller? Never dove into a transmission, Can this job be done by a rookie?
i have a 2007 sportsman 500 EFI with 8000 miles on it; that died on me.
