2005 Yamaha Grizzly 660, 4wd, 2562mi/607hrs . Runs and rides great, but does have a motor noise....not terrible, just some ticking there somewhere, timing chain tensioner/clutch/valve noise?  Have not looked into it, nor will I, this is a trade in, came in like this. Not loud, can just hear it reving up the machine or riding...so that's the deal. Equiped with a winch, fully automatic trans with Hi/Low range, selectable 2/4wd/Differential lock, independent suspension, trailer hitch, and digital dash. Looks nice, bodywork in good shape, some light scuffs or dings, good tires front and rear. Everything works well as it should, brakes, lights, battery, 4wd, etc-----Pretty nice machine actually, just has that rattle/tick I feel is motor related...No smoke or leaks, runs strong.....Take a look, ask me any questions, WI buyers to add sales tax, out of state no tax collected---Thanks
