MSU 500 hard to shift gears

Hey all!

Uncle's got a Massimo MSU 500 that he's been having some trouble with and I've been trying to help him out. He bought it used from some guy and I don't think it was in the greatest shape when he got it. The only thing he's done to it is add his Army Air Cav and Vietnam stickers to it. 

Started off saying it would shift really hard when setting off. Found the dipstick and it was low! So did an oil, air filter, oil filter and spark plug change for him today and it's setting off 1000 times better now. However, it's almost impossible to shift the gear lever. We still had the engine cowl off and I was having to tap the lever on the engine end with a hammer to get it to shift. I don't think it's because of how hard he was pushing the brakes because he seemed to be pushing pretty hard. Got it loosened up a little but still really difficult to get it to move between H L and R. 

There is what looks like a flashing front diff on the panel when it's running, and a noise coming from the front diff/axle but I don't know if that has something to do with it. 

Uncle ordered the tune up kit from Dr Motorcycle and he included gear oil, but can't for the life of us figure out where we check this and where it needs to be changed. I've read somewhere that we need to check the diff levels, but that wouldn't make a difference in how it shifts would it?

Any and all help welcome as I'd like to get Uncle's side by side running again and allow him to get about his property again.

1st. You should always be stopped with your foot on the brake in order to shift these things. Mine has an interlock that will do just as you are describing. 2nd, I don't think they like to cold shifted without the engine running and your foot on the brake. Also, on occasion, I have to coax mine up into low gear and hold it until I'm moving. I've played with the linkage adjustment several times and got it where it shifts good enough for me. I bought mine new (2017) and it has never been 100% in that area.

      2013 UT 500 won't go into reverse.
      By lonerider98
      At the end of last year my Coleman UT 500 will not go into reverse. I can hold it over toward the reverse to move it nut it won't lock into reverse. Anyone have this problem? Winter is just about over and going to have to get this resolved. Thank You!

      trying to finish assembly "new" 2021 Coleman ut 400
      By buckrub
      Hey guys! Newbie here. I'm an old man who's better with plowing a mule (4-legged kind) than these newfangled beasts. I, and a friend of mine, just bought new Coleman sxs and are having to finish the assembly. I've been reading on this site and I'm falling on the mercy of you experts. The only way I'm an expert is that an "ex" is a has been, and a spurt is a drip under pressure. LOL First off, the 2 buggies have no ignition switches. They seem to mount on the dash, not the opening in the steering wheel shaft cover, so we ordered new ones that are supposed to fit. They are 8 inches long, and have a 4-wired white plugin which is slightly rectangled when looking at the end of the plug. The trouble is there's nothing to plug into. There is a three-wire grey plug close enough to reach the four-wire plug, but of course, they are not compatible. 
      Secondly, the blinker, light, ect. unit on steering wheel just spins around when touched. I see no way in heaven or earth to secure it. I've looked at a diagram on the Powersports site, but can't detect how it mounted. Fellows I'd be so grateful for any help with this. Me and my mule will even plow your garden for free, for your help. LOL

      By Hi sun 500
      hello everyone, i just joined this forum to try my luck, few days ago i bought an old (dont know exactly), 2011/14 hi sun 500cc ""carburated"",  was not running at the time, but i fell was a good deal and decided it to bring it home to play with it, this is the issue, i bought and installed a new carb, and pump, i repositioned the battery location and upgraded to a "car batt", reconnected the fuel lines and started it, but it only runs with the choke ON, i checked the bowl, it does have fuel,but for some reason wont inject it to run, i came across a video that say that ""the body small tank had to be connected for the cart to run" (was deleted when bought), sure enough i got it to run sporadically , but the so called ""small body tank'' often runs out of fuel and wont refill itself , i had to couple times do it manually, so how does that small tank works ?..what does it do?..and why if  bypass it , the cart wont start?....any help?..thanks so much!!!
