Hisun 2020 Strike 550 having trouble switching gears

[techno10]

Had this utv for a couple of months and bought it with this problem. Sometimes it will move thru the gears with no problems, but most of the time there’s a resistance to go from one gear to the next. What helps is to give it a little gas to get it to change gears. I’ve tried adjusting the turn buckle connected to the gear shift, but didn’t help.  Anyone have any advice?

You mean between high low and reverse?

How high is the idle speed? It should be ~1400. If it's too high it may have issues.

What are you using for engine oil? Is the level high enough? Is it MA approved for the wet clutch? If not the clutch may be engaging partally at idle causing it to be dissicult to shift.

[techno10]

Yes it won’t shift between park, reverse, high and low half the time. 

I’ll double check the idle speed, but I think it’s good. 

I’m using a synthetic 10W/30 synthetic oil, the manual doesn’t say synthetic, but the weight is correct. I just changed the oil, but had this problem before I changed it. 
 

only has 38 hours and 310 miles on it.

Is it a "motorcycle" oil with the MA or MA2 rating? If not the clutch is likely sticking.

What oil is it specifically?

[techno10]

No it’s not a motorcycle oil, car oil API SE or SF rating, but that’s what the manual is calling for. 

[aefron88]

These unit have a wet clutch. Modern car oils have energy conserving slip modifiers that prevent the wet clutch from working properly.

Switch to a "MA" approved wet clutch oil and it will likely fix your issue and keep from destroying your wet clutch in short order.

Checked the rpm and it’s right at 1400. 

Ordered some Club Cadet oil that’s a UTV/wet clutch oil. Will see if this helps.
