Does anyone have Dyno sheet that they can post? I would like to see the HP/TQ numbers for the Chery 1100, I know the peak numbers but I want to see the power/tq curve.

I am working on adjusting my fuel controller and have a flat spot up top that won't seem to go away, I want to know if the motor just flattens out or if it's a fueling/timing issue.

The flat spot could be a volumetric efficiency problem. Look it up. For short it is the efficiency in which air can flow through the intake on to the cylinder chamber. The speed of this air varies with engine RPMs. It wouldn't be uncommon for an engines port configuration to have a point where the air flow speed is such that it fights itself through turbulence conditions. This could cause a flat spot. If you want to get the most out of your engine you need to first match the ports and open then up in the head for more efficient flow. Done properly, this alone without the controller could give you another 10 to 15 HP. The ports on the Joyner Troopers are vary poorly matched or worse. I'm talking about as much as 1/4" to 3/8" which is ridiculous. Then go to tuning your controller.

      Looking for a left rear shaft carrier (just the carrier) for a 2007 Joyner 1100 sand viper
      By rdc
      Hope I posted this in the right place. Looking for the left side shaft carrier where the rear bearings go for an 1100cc sand viper, I understand an 800 cc carrier will also work. I need the old style two bearing with the spacer in the middle, the new style with just the one wide bearing wont work. If anybody has one I'll buy it right away. my email is [email protected]

      MSU 500 Fuel Pump Ground
      By Kierobi
      Have a MSU 500 that we got from my wife's uncle a while back. We've had it running and hauling around the property but it stopped a few months ago after what I thought was running out of gas and I'm just getting to looking into it. 
      Had fuel to the injector but nothing coming out the injector so swapped with new injector and installed inline filter in the supply hose from fuel pump. Tried again and still nothing but noticed this time that I can't hear the fuel pump priming. 
      Pulled off the electrical connection and I'm getting 12V to the fuel pump but it won't run. Put it on a test bench and got it to run so put test lamp between +ve and -ve terminals on the connector and nothing. Checked against the passenger seat securing post and get a light. 
      Tried chasing the wire back and think that the ground is through the ECU but not 100% sure. Can someone confirm for me? And if it is through the ECU, is the ECU just grounded against the frame or is it wired through to the battery?
      Thanks in advance and hope this all make sense!

      I am sure I am forgetting something.
      I am parting this out of ebay right now, I just picked up another project and could use the room. No I will not take less than $700 for all of it or $200 for the frame. I do not need to sell it, I will make far more parting it out but would like the extra space in the garage.
      If interested I also have an 07 1000rr engine setup I would sell with the buggy for $650.
      Thanks!
