I'm looking to purchase a 2015 Massimo 550 that might have an issue with it's throttle position sensor.
From the fella selling this UTV, he claims its to set the idle on fuel injection because the engine will not stay idle or when it starts sometimes it idles too high.
My Question if anyone had any issues with their Massimo 550 and if it was actually the TPS or something else that would allow the machine to idle correctly.
Thanks!

Hi I'm about to order parts to do a bunch of work on my Massimo. Does anyone know if there's a difference in the top end kit {piston, Cylinder, Rings, Gaskets, Piston Pin} if it has a carb or EFI? I'm EFI and I think some came with a carb so I thought i'd ask before making a mistake...
Thanks Jerr

Was using the machine all day to haul wood...no issues until the end...
When I try to start it, the dash lights come on but starter does not...seems like no power to the starter.
It is in park, but when I put the brake on to start, it registers N.
Won't start in neutral either...
Tried rocking it, did not help...
Help...

As I tried to do a conversion with the Yamaha 660 motor, I realized the 660 was never fuel injected so it would not work for the fuel injected hisun motor swap. But the good thing is the hisun 750 motor is a clone of the 660 Yamaha but with the components for the fuel injection (cam/crank position sensor). So that left me with a new rebuilt Yamaha 660 and still a broke 750 hisun motor. I took apart 750 think the timing chain had broke from all that I've heard about these motors. The chain was not broke, but just off cam and crank gears! The chain tensioner was at fault! I've ordered Yamaha 660 replacement parts, chain, two exhaust valves (which got bent when chain came off while motor was spinning) and seals. The piston has 2 little nicks where it had hit valves but no damage otherwise. The head is being redone at the machine shop and I'll be putting it back together in the next couple of weeks. Also I finally tracked down a Service Manual with all the info on the 550/750 Challenger.

I just purchased a used 2023 Massimo warrior UTV SxS 1000mx with 600 miles on it. I didn't even get a full day of riding and the driver's side rear axle broke. I'm pretty sure it was already going bad because we would hear a noise once in a while. I'm wondering if anyone else has had problems with theirs. Also looking for places to buy accessories.
