2013 Massimo MSU 500 Weak


Recommended Posts

I have a 2013 Massimo MSU 500 project. I just recently got it running after sitting in pieces for an unknown amount of time. I replaced the wet clutch and drum, the primary clutch and belt, the spark plug, ignition wire, and ignition coil. I cleaned the fuel tank, replaced the fuel lines, fuel and air filters. I adjusted the valve lash and  the throttle cable stroke. Now to the problem. It tops out in high gear at about 4400 rpm at 27 mph. It tops out in low gear at 5200 rpm at 28 mph? It will rev to about 7500 rpm in neutral. I'm guessing I just don't have enough horsepower for some reason. Ideas?

Update: I just ran a wide open throttle compression check and it's 135! According to the stats that I dug up it's supposed to be between 163 and 210. So, that's not good. Also when I removed the spark plug it was chalky black with soot. So I've got something else going on, I'm not sure what yet. Grrrr!

      I have a Massimo 400 Buck that overheats and the antifreeze blows out of the motor everywhere! I don’t have to be doing anything but just driving through the field.  It only has 26 miles on it.  I don’t think the fan is turning to cool the motor.  Any ideas how to fix this?

      I have a 2018 Massimo Buck 400 with 278 miles. 
      Having issues with my brakes. Took the buggy hunting and when I let my foot off the gas pedal it pulls without pressing on the brake. I looked and the pads on all 4 wheels are all toast. The E-Brake hasn’t been on since I have had it. I am guessing it may be a master cylinder issue because all 4 pads are gone. They all seem to have worn evenly that’s why I think the master cylinder. Just got the machine used from a older couple and they said it sat for some time in there pole barn. Possibly the brake lines? Calipers? I took one brake apart and when I depressed the caliper it didn’t stay. Any help is muck appreciated.

      It's not immediately obvious to me how to wire a remote control (wired or wireless) on the Sector E1.
      Has anyone here done this? Do you have pictures on how to get to the wiring?
      Thanks!

      Just got this kymco 450i Uxv from a guy, drove it around before I paid. Got home drove around town a little while the next day and it started squealing and amd didn’t want to go. Got to looking at the clutch, that’s were the noise is coming from, the primarily sounds like. Maybe a bearing in there cause the grinding noise and it only makes the noise when you go to move.

      Hello 
      I have a 2022 Massimo t-boss 550. I’m looking for a fix for my timing problem. It keeps getting out of timing. Now I’m trying to find the proper parts for the linhai motor. I’m looking for tensioner chain and gear. If there’s anything else I can do to fix this issue please let me know. Unfortunately I can’t afford to get something better so I got to get it fixed. Thanks in advance.
