Yes you are right about an certain oils for an wet clutch...That is correct...I do agree on that but I am looking at manual now an don't see wet clutch on this machine......The clutch is an torque converter sytle drive system.. with belt drive....

 

I do agee with you on an wet clutch uses an certain type oil.....And yes would cause slipage and sticky clutch...But I am looking at manual on this atv that is mention an see an torque convertor type clutch with an belt drive....Which is an dry clutch system.......

 

He said Kodiak......But an grizzly is the same set up..Dry clutch...

 

Heres a diagram of the inner workings of the belt drive: CLUTCH CARRIER ASSY YA5GH-16620-00-00

You can see that they had that type of setup from 2000 on up. Also, number two is the wet clutch, number six is the seal. You can see that the wet clutch is separate from the rest of the belt drive, hence why you don't see it when you pull the cover off for the belt drive.

 

Google up wet clutch for your make and model you will see it does have a wet clutch .

 

Agreed - the Kodiak / Grizzly 450's definitely have a wet clutch that drive the Primary Sheave.

 

Problem with with Yamalube and Honda GN4 is there not Full synthetic but have the full Synthetic price anyways.

Goggle "Synthetic vs conventional oil" Synthetic will come on top every time. Ones made in a lab the other is made from dead reptiles.

Any Full synthetic motorcyle grade will do and all motorcycles have a wet clutch.

 

I went to Auto zone and they have Valvoline ATV 4 stroke motor oil 10w 40 JASO MA certified.
I just need to get the 10w 30 . It best fits my temperature riding range...

 

Not sure why any one would buy 10w-30 over 0w-40.

The "0w" means it made for much colder weather start ups, and the higher "40" means it handles hotter temperatures once warmed up. It just a "do it all" grade of oil.

Only in a lab could they come up with this grade, thats why 0w-40 is only avaible in Synthetic. It made for the Arctic or Death Valley conditions.

 

Yeah a 40 weight oil would be better for old worn out engines but 30 does just fine..
Matter of preference.
