As I tried to do a conversion with the Yamaha 660 motor, I realized the 660 was never fuel injected so it would not work for the fuel injected hisun motor swap. But the good thing is the hisun 750 motor is a clone of the 660 Yamaha but with the components for the fuel injection (cam/crank position sensor). So that left me with a new rebuilt Yamaha 660 and still a broke 750 hisun motor. I took apart 750 think the timing chain had broke from all that I've heard about these motors. The chain was not broke, but just off cam and crank gears! The chain tensioner was at fault! I've ordered Yamaha 660 replacement parts, chain, two exhaust valves (which got bent when chain came off while motor was spinning) and seals. The piston has 2 little nicks where it had hit valves but no damage otherwise. The head is being redone at the machine shop and I'll be putting it back together in the next couple of weeks. Also I finally tracked down a Service Manual with all the info on the 550/750 Challenger.

Spent today at a Honda dealership looking at their 520 side by side, then on the way home past our Lowes noticed they had several new UTVs on site, so we U-turned and ducked in there. We were impressed that all that came for $9,999 metal whole length skid plate, nice sized bed, roof, windshield, side mirrors, winch, upgrade looking tires… all of which would have added thousands of dollars to an already expensive Honda 520. Now Honda does have a great reputation from my trusted UTV experienced buddy, so it has that going for it.

Hi Joyner Gang
New to the Joyner group. I'm making long travel for the 1100 Sand viper. I'm trying to make something that will work as well or even better than the RZR Rino etc. At this time the front has 14" travel rear has 16" of travel. Still developing the suspension. comets are welcome. Ask questions and I will get back to the Forum

Hello,
Background: Bought a used 2012 700, added 2 small LED lights, wiring for a sprayer and changed front CV axles.
Had no electrical issues until recently. The old battery stopped charging so we got a new one, Rhino still wouldn't charge it.
-Started next day, drove 15-20min, then out of nowhere the check engine light came on and temp too. 4WD started to automatically engage and disengage repeatedly. Charging display started jumping all around between 11 to 13 to 15v.
-Relays, fuses, and battery connections seemed good.
-Continuity on rectifier would jump btwn OL and 00.0
-Rectifier wires from stator all read 20-21v at idle
-Rectifier diode test had 1 bad reading. So, I replaced it with a new one (but still using original plugs)
Started it up, still shows no change (12.1v idle, 12.8 with some RPM)
Also, I feel like now I maybe also smell burning plastic?
Does anyone have experience with this problem or have a recommendation of where to go next?
