First post. Just got gifted my 94 year old MIL's Mule 550. She can no longer use it and gifted it to us to putt around exploring the 710 sq mi Natl Forest we live in. It has had a long hard life at her horse farm with 2,438 hours on it and very little Maintenace. I'm doing fluids/filters now and need to do a valve check. Does anyone have the specs? Thanks for any help.
New to me , '04 with 2,438 hours. 286cc air cooled single cylinder. Anyone have them? I've seen set both at 005, 010, 012, 015, intake 012 and exhaust at 015. lol
I have been doing a little research on which engine oil is best for UTV engines. There seems to be some disagreement over using a good quality regular engine oil, and the necessity of using "M2" (or wet clutch suitable) oil. My understanding is the "wet clutch" suitable oil has less friction reduction properties (hence a more responsive clutch with less slippage). While less friction reduction properties would seem to be better for the wet clutch... it would not be best for the internal engine parts like camshaft bearings and other moving parts where friction is detrimental and would lead to premature failure. Some folks swear you need M2 oil, while others say they have been using regular motor oil for years and their clutch is just fine. Could they both be right ???
Any thoughts ?
