Pretty much all UTVs are like that. Sometimes you have to go in and out of a gear a couple times to get it in. I have driven Rhinos and RZRs that do the same thing. You might need to re-adjust your shifter if the selector is in one gear, but the dash reads a different gear. If that's not the case, then it is like a woman. Just play with it a little til it gets into gear!!
First thing to do is to check youre idling rpm,engine up to temp,set idle at 1750 rpm i believe ??? anyway just turn it down a little,
when the engine brakes in the idle goes up, which in turn makes the clutch want to engage i.e hard to shift,-- o-- and always step on the brake.
With the way the trans gears are cut, it has to be in the sweet spot for it to go into gear. Bumping the gas with a little pressure on the shifter will help when it is in a bind. We all know you can't shift while your moving but I have noticed if you applie alittle pressure and make your shift when just before you come to a complete stop. You basically are coming to a complete stop like you should but just before the tire stops you can slip here into another gear.
