I have a Joyner Mini Viper now and I drive it on the street on a regular basis. It runs very comfortably at 50 on the road (about 3000 RPM). I have a trooper now and would like to drive it on the street.

The problem I have is the top speed on these is way short of what they advertise. I was thinking of purchasing a 30’ set of tires for the road (is that the largest that will fit), but I don’t know if that would be enough of a difference to allow this to go at least 50 comfortably. My thought was I would put the off road tires back on it when I leave the street so I don’t impact its performance.

Does anyone drive their Trooper on the road? Any other ideas how to increase the speed?

Thanks

Bill

About the only thing you can do at present is bigger tires. Some of us run 31-10.5R15 tires without problem and you do get better gearing for the road. We use them for off road without any preformance loss other then a bit of low gearing preferrable for rock crawling. However, ithey will hit the wheel well when turning. This can be modified easily with a big hammer. Doesn't need much. If you want to be a glutten for punishment, you can redo the framework there like I did. With 31" tires, you will be running 50mph at the same RPM you now run at 43-1/2mph or about 4500rpms.

Thanks for the quick reply Lenny. I think that difference would work for me. I looked up some of the ITV top speeds and the RZR was the highest at 63. I'm pretty sure this will be faster than that especially with the larger tires.

I was curious where you were able to find your wheels. I did find the Vision Buckshot wheels on their website, but couldn't find a vendor to purchase them. I also found the ITP SS Alloy SS212 wheels on the ITP website, but again no place to purchase them. Also - I was curious if 15X7 or 15X8 would work better. I'll probably trailer it to most of the place to ride off road so I don't mind swapping wheels before I go.

Like Lenny I also run 31" tires but did not redo my firewall. A little work with a LARGE hammer in the right areas allowed the tires to turn. I have easily cruised down the freeway at nearly 60 mph without redlining my Trooper.

I get regular alloy rims in 15". They are generally real cheap if you look around. I then bore them to fit the bolt pattern. To do this, typically the holes overlap into the inside edge of the center hole by about 1/8". Because of this, a milling machine with a center cutting end mill is needed to bore the holes. I then use a 3/8" thick round alluminum plate, drilled the same, like a big washer under the lugnuts to compensate for the holes being into the center a bit. I also replaced the smaller bolts and went to 14mm lug bolts. All my rims are that way including my paddle tire rims and never had a problem. Have to just be careful to center the wheel in the mill then then you can dial out the hole location. One hole will also touch into one of the other existing holes if you use 5 bolt rims like I did.

      2016 Hisun 500 runs rough no power
      By CapnWalleye
      Just picked up a Hisun 500 that had shift issues (corroded fan gear) which I fixed. It also didn't seem to be running smoothly then all of a sudden it got worse. It seems to miss on both idle and when pushing the gas pedal to the floor and doesn't seem to be running at full power. I've been working with a local person who is walking me through some steps, but I'd like some input from this group as well. What I've done:
      - drained the fuel tank and replaced it with 93 octane fuel and added heet to help with any water problems.
      - replaced the fuel injector.
      - disconnected the battery (several times) to allow the module to reset.
      - set the valve clearance, both intake and exhaust, within specs ... intake was tight but exhaust seemed fine.
      - replaced the battery.
      - replaced the O2 sensor.
      Nothing has helped. Not sure what the next steps are, but would appreciate any expertise that can be offered here.

      Joyner R2 2008 800cc ECM code reader Lite or OBD port install
      By staind
      Looking for information on installing a OBD port or a lite to read codes in ECM. 
      I can not find a OBD port or a lite to read codes on this R2 with 800cc. 
      I have code readers and adapters for most ATV's. From what I've found so far. They don't have a connection for to read codes. I may be wrong. That's why I'm asking. 
      This R2 has had new IAC, TPS, MAP, fuel pressure regulator and fuel pump replaced. This was done by neighbor to try to stop surging. It still surges on start up and then settles down. But once you hit the accelerator it revs up to 2000+ rpm and stays till you block off IAC port in throttle body with finger. Once you do that it once again settles down and idles perfectly.
      I want to know what the ECM is reading to help dio it.
      This joyner is the first one I've run across. Well second one in a week. (my neighbors 2 of them) The other was a trooper with the 1100cc chery motor that had been setting for years. After cleaning up the fuse box connections. It runs like a top. Had to replace all gages with aftermarket gages. Water, oil, gas, amp. Only problem one was the water temp using original sending unit. Had to install 150 ohm resistor on the input wire to get it to read correctly + - 5 degrees. Close enough. Gas sending unit was/is for a boat tank 6" tall. All SS so it should last forever. 
      thanks Dan D. aka staind
