I have an R2-1100cc witch is almost like a trooper with a different body style. After I turn the ignition on, I have to wait about 3-5 seconds for the gauges to cycle before I can start the engine. It probably has something to do with the ECU "booting" up. I don't think the ECU gets power until the ignition switch is in the "ON" position. Like the computer you are using now, you can't turn it on and use it until it boots up. At least that'w what makes sense to me.

I have a Renegade but the wiring is probably close to the same. Take a close look at your speedometer and tachometer connections. There's one wire that goes to all of your gauges including the speedometer and tachometer. A break in the wire at one of those two (speed or tach) will interrupt the power going to the rest of the gauges. That's the only thing common to all of your gauges (other than the fuse which you said is good). I should ask if your warning lights work. They are powered from that same wire. If they don't operate, then I'm leaning to a bad connection at the speed or tachometer.

The 825i uses the exact same Chery engine as the Renegade with the 812cc engine. It's transverse mounted to accommodate the CVT transmission. It wouldn't surprise me that much of the Trooper engine parts (1183cc) are interchangeable with the 812cc engine. The 1183cc looks like it's an 812cc engine that has been modified to accommodate the extra cylinder. 812cc ÷ 3 cylinders = 270.666cc for each cylinder. 270.666cc x 4 cylinders = 1082.666cc

From your description it sure sounds like you have a fuel starvation problem. I would keep the fuel filter before the fuel pump to protect the pump form failure. Your fuel starvation problem could be a crack or loose pickup tube in the fuel tank that is exposed to air above the fuel level inside the tank. Another owner on another board went through his entire fuel system. Cleaned the tank, installed the filter before the fuel pump (his was installed backwards), replaced fuel lines, cleaned the pickup tube, added a vacuum line from the fuel pressure regulator to the intake air plenum. His problem was fuel starvation after about 15-20 minutes of operation on level ground. But his issues may lead you to a solution. I doubt he had to go through all that, but he cold almost guarantee that he'd fix the problem.

The torque curve and the horsepower curve are different. But one unique thing about these curves is they meet when the engine RPM is 5252. It's an engineering thing that you can research. That is where the engine at its highest efficiency but not necessarily where you'd want the engine to operate all the time. So spinning the engine faster results in less torque and horsepower unless you add a super/turbo charger. I would be concerned with spinning these engines much faster than about 6000 RPMs for a long time that the engine would stay together.

Thanks for checking on that for me. I was afraid I didn't have a 5th gear even though the shift lever was in the 5th gear position. I just hope my engine doesn't bust a gut traveling fast. The tach can be a backup speedometer and vice versa. Thanks again.

If any of Joyner owners are out and about, could you please let me know what your engine RPMs vs Vehcile speed is when you're in 5th gear? My Renegade sounds like it's wound up real tight when traveling. For instance, I get about 10 mph per 1,000 RPMs while in 5th gear (45 mph = 4500 RPMs). Is that normal? I'm used to lower RPMs. Other ATVs & UTVs running round my neighborhood that sound like their engine RPMs aren't that high.

The owner doesn't want work on John Deere 825i Gators or Kawasaki Mules? Those have the same engines as the Joyner Renegades with the 800cc (812cc) engine.

Hey, Brandon! I'm looking for a USFS approved add-on spark arrestor for my 2014 Renegade R2 1100cc. Do you have them or do you know who carries them?

Since no one has replied ... It has to do with the CVT. CVT use centrifugal weights to adjust the spacing of the clutch cones based upon engine RPM and vehicle speed which, in turn, changes the ratio of the drive clutch and the driven clutch. Tuning is simply going to heavier weights or lighter weights based upon the type of riding you do. Do a search on "CVT Clutch Tuning" for some excellent articles, one of which is on this site: http://bikemanperformance.com/tech-tips/general-clutching.html

I've been enjoying the site for a few months. When I got my Renegade, I just had to sign up. Thanks! I'm thinking of putting together a review on my Renegade (likes, dislikes and mods). It won't be 100% complete because I still have a lot to learn and investigate.

New to the forum, of course. Just bought a used R2 with an 1100cc engine. Don't know why it took so long for Joyner to do that with the Renegade. Hope to learn a lot about my machine.?
