02 MT Cat 800 144 EFI, 2800 miles. Starts and idles great. When you get up to speed (around 5500 rpms) it will surge approximately 200 rpms. The surge gets more pronounced and rapid the faster you go. Once warmed up it seems to be worse and under a more severe load (going up a hill) it has difficulty and will barely make it up, feathering the throttle seems to get you up the hill. I have swapped out secondary clutch and coil from an 02 MC 600 with no change. I went through the primary clutch and no change. The fuel injectors seem to be working (at idle) I have run it with the APV servo wires disconnected with no change. I have run it with the Servo wires connected and the cable held wide open with no change. Compression was low but I'm thinking maybe stator. Can someone give me a tutorial with specs for testing the stator and would it be the same stator as a 600??? Travis
