Decided to do an oil change on the Massimo ...drained oil, screen was very clean even tho oil wasn't. Then went to remove old filter.. holy crap ..I tried every tool I have, could not budge it..Went to store and got one of the end cap type..fit nice and tight, put a 1/2 in drive ratchet on it..nope..not moving. Put a 18 on breaker bar o. It. The inside of the removal tool broke off!! Had to weld it back together. Put a pipe on the bar for more leverage. Finally broke it loose..
I have never seen a filter in my 55 yrs of working on engines so tight..And i was the one who put it on 2 yrs ago. JUST HAND TIGHT!

2018 Massimo 700 MSU. The machine started burning oil all of a sudden. One day fine-- next morning burning oil. Looking for advice. Do I pull the engine to inspect the top end or can it be done with the engine in place? Pro? Cons?
Any and all assistance is greatly appreciated in advance.

Just bought a brand new 760 about a month ago. I'm at 20 hours which the book says is when you need to change the break in oil.
I must be crazy, but I can't find the oil filter. I've googled a million videos...everything seems to be 2019 or lower...and/or a 550. They all show the filter easily seen by looking in past the rear passenger tire on the engine. There is absolutely nothing there on mine.
1.there seems to be very little info if you Google a 760, or anything Massimo newer than like 2019.
2. Does anyone have a current model year 760 that can answer my riddle for me?

Hi All,
New here, but bought a 2022 Sector 750 brand new last march (old stock up here in Canada)
It's a good bike so far, but I have noticed a quirk and was wondering if anyone else has had a similar issue?
The issue I've had is if I leave the utv parked on any incline, not even a major incline, and leave it to sit for a while (day or two) it will not start properly. It will turn over and not fire until I press the gas pedal, when it will run and rev up, but if I let off the gas it will die. It will keep doing this until I either start it in gear and drive it for a bit or leave it in neutral and roll it down the hill to flatter ground. where it will have to sit for a while.
If I park it on a decline there is no issue. fuel is not low, it's occurred a couple times now.
Any thoughts on the cause of this? Dealership just says bring it in and let them take a look, at my expense of course.

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 ?
