Burned down the mag side twice. At idle the temps are close at 315. In the shop with the belt off. But as I increase the rpm to 6800 the mag side drops under 300 and the pto side goes to 700. Things I have done. Changed plugs, reeds, injectors, ecu. I have checked the voltage at both injectors. All four spark plugs are firing. Set the power valves and made sure they open at the correct rpm. What should the exhaust temps be with the belt off in the shop?
I guess the next thing is to pull the engine and pressure check it. No codes are showing. I have also switched the injectors. Installed a new Digatron with new probes. Will the Cat dealer tester show anything if there are not codes showing? It is getting more than enough oil. I set it up just for testing. The pistons had scores on four corners with the top and rings looking good. I sprayed starting fluid around the throttle bodies, mag side and along the clutch with no results. Both cyl's have 120 lbs of comp. 07 M1000 with 1300 miles.

Had one do the same thing, are you replacing with new AC parts and have you Checked the piston tolerance.
