I'm working on a Coleman UTV 400 that has a rough idle, owner has had it for about a year. When I say it has a rough idle, it doesn't have the continuous smooth running sound. At times you can hear it kinda skip, sputter, or like the RPM has fallen (RPM stay constant according to the gauge) It's not as bad as it was after I replaced the fuel filter and fuel injector (both are Chiki) not sure if that is a quality brand at this point. Checked the spark plug, it was a little foul, but not too bad. (Since the engine is still idling bad I'm going to replace that) Cleaned the throttle body making sure the carbon and soot has been removed, and the air-filter has been cleaned. New fuel is being used so it's not old or been standing. They did tell me that they were using non-ethanol fuel, not sure if that would be causing the issue. Next two things I can think of that maybe the issue is the O2 sensor or the valves need adjusting.
Thoughts and suggestions? Thanks in advance.
I have alot of issues with this machine that I'm trying to figure out and fix. Today when I was fixing the shifter I see this cable connection that is not connected to anything. I looked and can't find where it might need to be. Any ideas would be greatfull.
Hopefully this helps somebody because I couldn't find any info on this runaway condition.
Drove 1/2 mile to the gas station and when I started up to leave the starter stuck on. Turn key off starter is still running~! Limp it home wondering what the heck to do, get it in the garage and pull the negative battery terminal to get it to stop. Whew, WTF?
Calm down and start checking things, starter is hot of course but nothing is smoking and nothing smells burnt. Pull battery cover off and start checking wires from battery to relay and relay to the starter. OK good nothing is hot, nothing is crispy and nothing is melted. Probably smoked the starter though. If this had happened to my wife and I wasn't around the machine would have run until the battery died and probably melted down/burned.
I'll get to the point to save you folks some time and trouble. Because this is a kymco machine you need 2 different Kawasaki parts to make this repair, and information is scarce to say the least. The switch and a sub harness to connect it to the machine's plug.
Everything works now, but the starter sounds horrible so I'll be changing that too before spring.
Good luck out there and hopefully this is just a freak occurrence, but if I were you I'd get rid of this kymco part and put the Kawasaki replacement in now.
Switch, Magnetic is part number 27010-0767
Sub Harness Start Relay is part number 26031-Y034
Please help I have a Massimo 400 buck that has an oil leak. The oil is leaking on the front side of the motor. It leaks out of a u-shaped steel pipe that has two banjo style fittings on it. I have tried using RTV and different banjo washers and have had no luck. It drips about one drip per second while it's running. I can't find parts for it at this time.
By TBoss 560 2023
Got a new 2023 TBoss 560 with 40 miles on it now. Noticed after about and hour of plowing snow coolant started hissing out the overflow tube. Initially made a pop or blow kind of noise and then saw some steam and smelt coolant. Coolent level is in the middle between low and high (running or not). Coolant under radiator cap is full when cold, appears nice and green. Checked oil doesn’t look milky. The temp ranges from 160-180 F running for 15-20. Noticed the other day there was some more coolant that blew out the overflow tube. I called the dealer and they said the system could be purging air. Dealer is 2+ hours away so wanting to get more thoughts before considering to bring it in. Also noticing hot/burning rubber smell but I think this is from the belt breaking in? Also notice the coolant smell from the exhaust when in higher RPMs. No white smoke from the exhaust. Also another possible issue. I notice that there’s a little bounce when on pavement. You can also hear the CVT kind of make noise with this bounce in tandem. Is this normal?
