New to the forum looking for information from the experts. Brother bought a Massimo hs700 from a friend, needed a new rear axle. Got it home drove it around a little (since it still had 3 axles)and noticed the speedometer reads zero. Replaced the axle and put a new spd sensor in it and still doesn't work. Bench Tested the old sensor and it worked. Unplugged and Checked the wiring from instrument cluster with key on and I get 6.8v from signal and 7.2v from the power supply. Isn't it supposed to be 12v power supply zero volts signal. Has analog speedometer.

I have owned my 2015 Hisun HS700 Crew for about 3 or 4 months now. I got it used and was supposed to run good but was not put all the back together from a stator upgrade due to previous owner said he was going to out a stereo system on it. Anyway I have worked it much more than I have rode it. I seem to work on it 2 days and ride it for a hour. Me, my wife, and 2 kids (10 and 18) enjoy it but the engine compartment gets so hot. I've replaced the water pump and burped the cooling system and any other thing I could think of to bleed the air out and think its good with no air and water circulating. Fan seems to run fine and be on about all the time. Changed the coolant twice and oil 3 times. I noticed the engine really has nowhere for heat to go because heat rises and no air flow at all. Has anyone had any experience in this area? Any DIY tricks or any advice in removing the heat out of the engine compartment and getting it to a tolerable temperature. Im about to sell it if I can't figure something out and go waste money on a big name brand but I won't have red legs and arm from engine heat burning me and my wife. They machine never acts like its to hot or anything but it feels like it is. Thanks in advance for any and all help.

Hi I’am new here.I bought old Hisun 2007 hs 700 carb model and it was broken complete engine,clucth, rear dif,oil leak,with out carburetor end second tank… I tried to fix it but I have some problems… And I need some ideas and experience about this model….

I have a 2011-12 Hisun Yard Sport HS700. Engine gets hot, but radiator does not. Changed the water pump, still the same. Service manual parts #15, 16, & 17 (pages 283-284) shows a "Save Temperture" #15, which looks like a thermostat. Service manual also parts #9, 10 & 11 shows it without a thermostat. Does this unit have a thermostat?

I have a 2012 Coleman (hisun) hs700. The cooling fan quit working. I replaced the water temp sensor/ radiator fan switch located towards the bottom of the radiator. That did not cure the problem. I also put 12v directly to the fan to make sure the fan was still good. I then took the harness off the new temp sensor and shorted it to turn on the fan and nothing. Is there something else in line I should look at? I also found the sensor at the motor and jumpered through it. Still did not work. Any suggestions? Thanks

Hello. I purchased this unit as a "non runner" with the intent of using the frame to build a go-cart, but once I got it home it seemed way to good to part out. The motor cranks over, and I have spark, but no fuel. If I put a little fuel in the cylinder it fires up until that fuel is burnt, then of course it dies. The fuel pump is not running and I have removed the plug and there is no power going to it. I have checked the safety switch on the brake pedal and its fine, I have checked the fuses, all good, but am not sure where to go from here. The shifter is missing on the unit, but the indicator light on the dash shows its in neutral, and the e-brake indicator switch is working as well. I am thinking of jumping power to the fuel pump next to see if it runs and if the motor will start. What am I missing? What can stop the fuel pump from getting power to it?
