Good mornin' all. Just joined.

I got an old 2003 Arctic Cat 375 Auto, and just bought a 2008 AC 650 side by side. Got a new starter, solenoid, and battery for the 650. Gonna change the crankcase oil and filter while I'm at it.

Anything I oughta watch out for from them that's done the starter/solenoid on this model?

Don't have a manual yet for the 650. Any recommendations for oil weight/grade?

Thanks.

Sorry I can't help with either of those models. I have a honda talon and a cfmoto 500 for the kids but welcome to the group!!

Like chase said I don't know, not familiar with those either. But if it has an internal wet oil bathed clutch. Be sure you use a oil designed for motor cycle or atu/UTV clutches. As far as oil weight. Should be able to find that info in the owners manual.

Or maybe use 10w30 or 10w40. The 1st number, 10 means both oil weights are the same thickness in cold temps. The 2nd number 30 or 40 is the thickness when they get hot. And the 40 is thicker than the 30. 

I made the mistake and put 10w30 in my blazer and it knocked for about 5 minutes until the engine warmed up. Immediately drained and put the recommended 5w30 in and had no trouble. 5 is thinner than 10 cold and I guess the tolerances were too tight for the 10w30 when engine was cold. Kept that blazer for another 10 or so years after that.

Some people say don't use synthetic oil with wet clutches some say it's fine. Personally I won't use synthetic oil in anything. But to each his own I guess. But if it is an oil bathed clutch it will definitely need oil formulated for wet clutches.

 

And welcome to the site.

Definitely use oil for wet clutch.. usuually 10W30 in cool climate ,10W40 in hot
