OK fellow Joyner people! I have a Renegade R4 in the shop right now. The man brought it to me as a "no start"... he said he went trail riding and got it stuck very bad, he left it overnight. The next morning went to get it and it wouldn't start.. he drug it home and somehow came to the conclusion it needed a new ecm... he gets a new one hooked it up and still no start... this is when I get it.. the ecm is laying in the floor and the two ground wires are not hooked up.. I ground the two wires and boom it starts up.. but only running on two cylinders. From what wire diagrams I can find the trooper has two coil drivers and the renegade has three. I have checked the coil and all the wires and all is good. I am not getting pulse from the ecm for the third coil... the old ecm cover was sitting in the floor so I compared the numbers, totally different! Called the place he ordered the ecm from and they are telling my the old number superseded to the new one I have. I checked the ecm on my trooper and the numbers match perfectly. So what I am saying is the new ecm they sent is a match for a trooper ecm... are they the same?

Thanks for any help!

Josh

If the numbers are the same, they are for the Trooper and that would explain the running incorrectly. Otherwise, the ECU looks for information from the tach and cam positon sensor to initiate spark. You might check there for a bad connection. Make sure your grounds are solid to the engine and ground the exterior of the ECU.

      I have a 2007 Joyner 1100 sand viper and  before it even get's to where the thermostat opens up the oil pressure get's so low I have to shut it down. What could fix this ? I thought about adding an oil cooler with fan, thicker oil, or removing the thermostat. Any advice?

      2004 250DL DIRT DEVIL. Hey y’all, I already know this is a long shot. But I am looking for a the “prick gear” assembly that makes reverse work for my external reverse gearbox. OEM PN D250.08.103 and its assembly. I bought the kart as a basket case, but I saw that the reverse box was present so I was optimistic.  Upon starting working on the buggy I realized there was a block off plate in plate of there the normal gear would be. If my understanding is correct that means the transmission no longer has reverse gear. I figured it’s just a standard bevel gear and I could probably find a gear to make work, but I don’t want to spend the time making all the other housing parts to shim the gear perfectly. Has anyone spare parts, or figured out an aftermarket solution from McMaster? I already know it’ll be a challenge to get this box to be happy again, but figured I would ask
