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

Just wondering if mine is the only one that’s seems very loud while driving. It just seems louder that other brands I’m use to. I guess you get what you pay for I’m assuming.

Is the cam sprocket a bolt removal or is it pressed on? Dang bolt is on tight. Impact wrench won't even move it.

My father-in-law has a Hisun 750. It has started to not change gears while running. He can turn it off, change gears, then restart and it will change. I thought it might have something to do with the brake but can’t find any info. Thanks in advance for any info.

Okay guys, this Vector 500 is killing me. Hisun 500cc engine (Chinese) About a year ago while riding slowly, I heard a tink and UTV turned off and would not start. Checked everything long story short, timing chain jumped off lower sprocket, slightly bent the cam sprocket phasers. Bought new chain and cam sprocket, set everything back to timing position, mounted chain on lower shaft sprocket and upper cam sprocket. Set the tensioner, cranked and poof, chain once again jumped off lower shaft sprocket. Again, repeated proper timing settings, remounted chain, cranked and poof again and again and again, chain keeps jumping off lower sprocket. Just to be clear, valves, piston and all components are look in great condition. Can't see shaft sprocket but to the finger behind the tight squeeze, all sprockets seem to be in place, or maybe not. Tired of fiddling with it. This was bought brand new at Home Depot and has less than 200 hrs in the past 3 years. Don't tell me to warranty it as that expired one year in. Talked manufacture out of McKinney TX and service tech was no help. My question to you, what am I missing? What next?
Dumbfounded 🤔
