Yes for sure the rear end likes fresh fluid all the time. Lol I know two rebuilds under my belt.Wife has a a 05 650 SRA. identical to a prairie just a different body. That bike screams! A crap ton of torque and pull. Little issues that arise on these is the carb tuning. Can be a real PITA if you don't know what your doing with it. Keep the fluids changed and snork it and she'll last a life time!
