Recently acquired a 2017 Challenger 750. Previous owner ran it low on oil so I had to do a top end. Starts and runs but it seems to be running very rich. There isn't too much information available for troubleshooting the EFI system. Air filter is new and I even tried running with it removed with no change. Some of the parts are relatively cheap, so I did replace the IAC and the MAF sensor. Could this be related to the TPS sensor or which direction should I head in next? There doesn't seem to be any adjustment on the TPS and I have read something about a WOT ECU reset but that didn't change anything. 

Thanks in advance

Check the 02 sensor connector. It has 4 pins and one of the pins on my unit was complete rotted away. Cut out both connectors, spliced wires together.

      2017 Massimo MSU 500 top end kit
      By Jerrys500
      Hi I'm about to order parts to do a bunch of work on my Massimo. Does anyone know if there's a difference in the top end kit {piston, Cylinder, Rings, Gaskets, Piston Pin} if it has a carb or EFI? I'm EFI and I think some came with a carb so I thought i'd ask before making a mistake...
      Thanks Jerr

      UT400 First Oil Change Overfull Milk Chocolate What to Check
      By Homeowner A
      Picked up an essentially new 2022 UT400 with 9 miles on it.  Decided to change the oil because it's probably never been done.  Pulled the dipstick and noticed it was overfull then went and pulled the drain plug and took off the filter and it was like brown water running out.  What should I start checking?

      2013 hisun 500 efi utv. No fuel, no spark
      By Robby
      Hello, I have a 2013 500 utv hisun. Was running ok and cut out while parked. Bike will not start now. It turns over, but won't fire. I have no spark and no fuel. I replaced fuel pump, ignition coil, spark plug, cdi, voltage rectifier and all the fuses and relays. Could bad stater cause no fuel because I can't hear the fuel pump priming. Any info on where to start looking for problem.

      2023 t-boss 550 belt slipping and found oil in belt housing
      By Cory J
      Belt started slipping when I used it in high gear. It works okay in low unless I'm trying to power it up a hill and then it slips.., Ordered a new belt and went to change it and found a good bit of oil in the belt housing. Has anyone experienced this? Belt looks fine. Only have 300 miles on this thing..
