I've had my Massimo 500 for about a month. So far I'm really happy with it and until today haven't had any issues . When It was delivered, the fuel gauge had one bar so I put a couple of gallons in to get me going. Still showed one bar on gauge but I figured not enough to register. Today I thought that I'd add a 5 gal can to top off. Well, I learned that the gauge wasn't working when, you guesssed it, the tank overflowed after a couple of gallons in. Still only one bar on gauge.
I could probably figure this out by starting with the basics (checking wires , the sending unit , etc. ) but before I got a-rippin and a-tearin , I thought I might save some time and I'd check and see if anyone had already had this problem and what the fix was. This is a 2007 with the electronic dash. Everything else seems to work . Any help would be appreciated .
This looks to be a pretty common topic and I've had issues with mine overheating since I got it back around the end of 2019. Started running hot again, thermostat was not opening and they sent me a new one. Installed that, burped the system for air all to no avail. Next in line is the water pump to replace, they sent me a water pump and when I got the old one off it was not turning freely to say the least so I'm thinking that could have been my problem. My issue now is getting the slot in the water pump shaft to line up with the tab inside the engine of the machine. Any tricks to doing this? Thanks in advance

Has anyone tried using an external electric water pump on these machines? I watched a video on youtube of one installed on a 1000 cc side by side that had chronic overheating issues in hot weather.. He claimed that after installing a Prius electric automotive pump from junk yard, inline in the inlet hose and bypassing fan temp switch, that the engine never overheated again. .. I am considering trying it on mine...................... Anybody else done this? .................. He did not say if he removed the mechanical pump or not.. would it pump thru that pump?
Hello Folks - newbie here with my first post so go easy on me. I picked up a Buck 400 in May 2020 direct from Massimo when they were doing a closeout sale on the 400 models. I read the reviews and was skeptical.
We live in a golf cart community we do not plan any off roading - just some very mild work tasks like hauling firewood / brush etc. Honestly, all we do is cruise around our neighborhood roads. I pulled the trigger b/c the price was cheaper than a 2WD lifted golf cart and the Buck had way more features.
We have a few steep hills and after about 20 - 30 minutes of cruising, my check engine light comes on. It only happens when we are going up or down one of the hills . We head straight home and things seem fine the next day. Light never comes on unless we tackle multiple hills during one ride.
Should I be worried?
PS - Unit is 4 months old and has 258 miles on it - barely broken in. I've yet to go full throttle on a flat or up a hill.
