I sell equipment and one of my dealers took in a 660 on trade. He knew I had been wanting a Utility vehicle. He called and said bring your trailer. I brought it home an took it out for an hour and about an hour every night for another 4 days. Long story short I bought everything for a total tune-up, when I got to the engine oil I unscrewed the drain plug and no oil. I have no idea how long it had been without oil. Engine seems fine, no ticks, knocks,smoke or anything. It does 38 mph so I don't think anything is wrong with the clutches. I'm baffled, this should have smoked the motor. What are your thoughts? I had planned on buying it, sold my wheeler, bought tires, winch, roof, gun rack, and a few other things. I'm in a tough spot with hunting season around the corner and no wheels. What would you do?

put sum mobil 1 or amsoil in it and keep going !

make sure u get wet clutch approved oil whatever it may be,

sounds like the clutch needs to be cleaned and maybe a new belt make sure its in spec, 1.32 is new - 1.19 is no good, with a clean clutch and new belt u will be back to 42 , with a cdi and a clutch mod u will see 55+


also make sure the oil filter is tight, sum had problems with the oil filter spining loose and dumping oil that way and blowing the motor maybe u just dumped out the last of the oil thru the loose filter and u turned it off b4 it blew ? :) lol

If I was losing oil, I sure would pull the top of the airbox off and see how much is sitting in there. These cars are famous for blowing oil out of the crankcase breather, and depositing it all inside the airbox, especially with a lot of full throttle operation.

A siphon break is a good investment.

C-Ya!!

damage is already done to the internals,shut it off,pull it all apart and rebuild it,if not a drop came out then its a ticking time bomb from here on out.....probably burned the cam saddles and toasted the bearings on the rod and who knows what else is toasted....if it hasn't blown up then now is the time to have it completely rebuilt...I have had no oil on a dipstick before,but never had no oil drain out of the crankcase, thats scarey....

Yea 17mm plug on bottom of case. I'm still baffled. Took it for a short ride to warm up for an actual oil change to look for brass and metal shavings. Ran like a dream. Iv had grizzly's in the past that sounded worse.

Maybe they recently changed the oil and its still clean and hard 2 see ?

You should let a warm engine sit a little to get an accurate reading on the stick.Well if its running fine I say drain what you can and put some good oil in and forget about it.

If it was going to lock up it would have done it long ago.
