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.

The conversion took about 350lbs. off the vehicle. It never rode great, but now I feel every crack in the road. I have backed off spring compression nut to the point just under where they would move around if suspension was at full extension, but it is still very stiff. I would like to put some softer coilover springs on it, but I have no idea what the spring rate is with the original springs so I would just be guessing on what to order. Does anyone have the data for the original spring compression rate? I am willing to give up a little ground clearance for a softer ride. Right now when sitting still the rear suspension is at or near full extension and the rear tires have several degrees of camber which will cause uneven wear if allowed to continue in this state.

Okay everyone, need some help here. I got my 2014 Bennche Bighorn 700 from my father inlaw. He has had it since new and as far as I know never had any problems with it until recently. It began with it being hard to start and having to give it some throttle for it to start up. Then it wouldn't stay running once it did start. If you go to start it, it will fire right off and only run for a split second and then die. If you give it some throttle it will start and stay running as long as your foot is on the pedal. While it's running its pretty rough and backfires. Here is a list of everything I've done so far. Initially I checked compression and it was low. I changed the cylinder, piston and rings. Took the head apart cleaned and laped the valves. Checked timing a few times. Adjusted the valves. New spark plug. Checked the air filter, it was fine. New battery. Changed the fuel pump because of a broken fitting. Changed the fuel filter, lines and fuel injector. Dumped the old fuel and put new in. Changed the air idle control, TPS, MAP sensor, Voltage Regulator, ECU and harness. I was getting codes 31, 107, 113 and 122 on the display. Once I changed the ECU no more codes have been displayed but still have the same issues. All fuses look good and as far as I can tell Grounds are good unless there are some I can't find. I'm at a loss here. Not really sure where to go. Compression was better after everything I did but I don't remember the numbers. I'll have to check it again if someone thinks that could be the issue. Any help would be greatly appreciated!

When traveling in the 40 mph range and throttle is released machine starts surging instead of a gradual slow down any help would be appreciated as dealer is clueless
