Splutter

Hi

Anyone have a chinese clone (Cazador 180cc) or similar experiencing spluttering when trying to run full throttle cruising? I'm not sure if there is a limiter on my model but it just won't let me cruise at anything over 45kph.

what are the tell tale signs of a limiter cutting in? mine splutters and almost cuts out the engine forcing me to the kerbside until it recovers and very annoying indeed! 

I just want to cruise at 50 or 55kph so the engine hums nicely instead of vibrating like the clappers.

Today I tried leaning the idle mix and its running better, spluttering gone but still missing the power on hills with 2 adults. also full throttle didn't shut down so I'm thinking almost got it sorted. 

Now tweaking the mix screw a little at a time on runs to find the best setting. then I'll take a look at the sparkplug as a double check.

Machine is 2 yrs old and 200km on clock as was garaged. Now have it almost running fine but now battery constantly draining after a few runs and meeting just with a click at the starter. 

I have charged battery, volt tested it and charging seems to have enough power and doesn't drop with engine throttle open so running should not deplete it. 

No sticking brakelamps but however front sidelights are always on whilst the engine is running. the rear ones obey switch. I pulled the switch connector cables apart and they are still on. they don't stay on after key removal but may be the constant drain I'm looking for. 

Any ideas guys?

update. 

Cdi changed, new plug and battery. same problem

have since discovered a split around the intake manifold where the carbs mounted on the engine. Seems when the engine revs theres a lot of engine pivoting & movement opening up the gap under load. Will get that changed tomorrow and hopefully report back with good news.

Update on Chinese UTV Cazador

Running well now, starting ok. 

Performance specs are for your reference. 

2 passengers cruising 30mph max 34mph downhill and 20mph uphill

Reversing has tendency for chain to jump. 

Going to Attempt to tweak shock preload settings for 2 passengers. Would preferably like to do it on trail but need to get wheels hanging to releive spring load.

so does anyone know if driving one wheel onto a kerb will releive the tension to the opposite wheel so enabling adjustment easily?

Shockers upped to 3rd notches back and front, rides firmer and chain adjusted but needed to sash clamp the shaft to get it moving. the bolts are too soft and one thread stripped. 

Sprocket bolts loose and a few others including castellated wheel nuts and shock mounts.

Handbrake lever bolt tightened, Brake mountings checked and steering tie rods. 

Now rides quieter and rumbling gone.

Starting easier and Electric problems finished. 

Update:- Headlights now way too low and need adjustment. Remounting Back storage box higher so can access the parcel shelf and maybe fit extra spotlamps to sides above mirrors if lights are inadequate. 

May have to adapt windshield as a fold down as get dazzled by lights at night and have to illuminate lamp and indicator switches.

I've just finished upcycling an old clothes rail to raise the cargo box and can now store gas, jump leads, Slime and pump underneath and covered with webbing to hold all in place. I was always looking at the wasted space with the original mounting and it had been put on off centre. 

You'll also notice the reg change to new foreign owner plate.

Still waiting on my 72w Cree lightbar to fit in the scoop on front to finish up.

By the way. "Slime"  for your information 

I've used it on my motorbike and mountain bike and it takes away the puncture stress of thorns etc. out on trails.

It says temporary but I've used it and managed to wear out my tire before needing to get it fixed.

Recent update. 

Light bar mounted and also reverse and interior LED's with a new fusebox mounted under dash with a centre switch plate. Very impressed with the light bar but wish i could fit stalks on steering column to dip, flash and indicate etc. but hey ho.. its doing well. 

Steering rods were both loose through vibration and hence steering was well out of line. Soon corrected with string and tape rule, adjusting tie rods accordingly. also the bolts on the knuckle were loose. 

I've opted for dry silicon chain lube on all steering ball joints as rubber boots all rotten and grease attracts dirt so Castrol lube it is. 

Note:- Chinese Tyres are soft as you can see fronts worn already with just 850km on the clock. 

Good note is first time out in heavy rain and floods and didn't have any problems, checked following day and engine  started normally. 👍

      It has done this since day one that we purchased it from Tractor Supply. I contacted the service man that Tractor Supply recommended and he told us that there wasn't anything he do to help us with. Has anyone had this same problem and can offer suggestion on to correct this issue ? It would be greatly appreciated.

      Its maker has affectionately dubbed it Teslaris, for obvious reasons.
      The Polaris RZR RS1 UTV has a one-liter, two-cylinder engine that from the factory has around 100 horsepower, making the 1,383-pound (627-kilogram) UTV very quick. But there’s always room for more power in one of these vehicles, and instead of fettling with its engine, one dune vehicle aficionado decided to swap in the rear drive motor out of a Tesla Model 3 / Model Y.
      We don’t know how many of the battery modules the put in the vehicle, but it doesn’t appear to be much heavier than stock and it goes up sand dunes with remarkable ease. Depending on which version of Model 3 was the motor donor, the drive unit could have either 261 or 325 horsepower, as long as the battery pack can supply enough wattage and voltage.
      Judging by how easily it flies up the steep sand dune, almost lifting the front wheels off the ground under harder acceleration, it’s safe to say it looks like a real hoot. The steep grade you see it tackling in the video uploaded by the electric UTV’s creator, Ron Cobbley, is located in the St. Anthony, Idaho sand dunes.
      We found more videos on vehicle’s official Instagram account and aside from how interesting it is to see an electric powertrain in an application like this (and how it changes the vehicle), we also noticed that you really hear the tires on the sand more. Usually, this sound is drowned out by the engine.

      The sound’s tone and pitch probably change with speed, giving the driver audible information to help him or her gauge their speed. You don’t really get this in a road-going EV driven on tarmac, which is why it’s trickier to drive an EV quickly - specifically because you have no way of knowing how fast you’re going just by ear.

      I thought the problem was electrical but I just found this in the oil filler tube. Does anyone recognize the part? I know I'll have to tear down the whole engine, and maybe I'll find the rest of it in there. Something beg enough to seize up the engine. That was the problem I was trying to diagnose.... 'Cause it's locked up. 
      Thanks in advance.
      Rick

      I acquired a Coleman UT400  just after Thanksgiving (2020) and find it to be quite different than most others seen on the web--the most visible difference is that the cylinder slants toward the rear placing the "hot spot" under the bed rather than under the seat (a significant improvement to my mind). THe curious prt of this is that neither Coleman nor  Hisun seem to acknowledge  this major design change. In fact the Owner's manual supplied with the vehicle appears tp haqve been written for a completely different unit--showing the ignition and light switches mounted in the dash (they are stalk mounted on the steering column on mine) and indicates that to change the spark plug requires removing the seat (the cylinder head and plug are under the bed on mine):

      I wrote to Coleman and they sent me a what is supposed to be the most recent "UT400-5" manual which is still wrong about 90%+ of the vehicle. Neither the Coleman or Hisun websites are of any use as their content provides no photos and very little information about maintenance or the engine/drive train in general.
      Is anyone aware of when these changes were made, or of any sites offering info re: this latest mode?  Currently I'm battling shift cable adjustment to find better and more consistent reverse gear selection.
      Mine also differs in that the parking brake is a single caliper and disc mounted on the rear differential pinion shaft (this seems to be a "5 brake" configuration I have found reference to.
      Overall it seems well designed and manufactured--the chassis welds are as nice as you could ask for and the castings and  machining are top notch.
      Any information or suggestions as to where to look would be appreciated...
      TIA
