I have an 09 M8 with an OVS turbo. I have put on 600 trouble free miles. Went on my last ride with no problems. Went to ride again 2 days later and the engine would not stay running. Pull the rope and the engine fires and then imediately dies. Occasionally it backfires as you pull the rope. Took the sled to the shop and it fired right up. Decided to put dielectric grease on all the conectors. Went to start it again and same problem. I have found the reason the engine is dying is due to no more spark. Unpluged the key switch and handlebare wiring harness and still have the same problem. I have tested all the sensors and stator minus the TPS. I did unplug the TPS because I know they will still run without it being hooked up. Same problem. I have a donor sled to start swaping parts tomorrow. Has anyone ran into this? I will let everyone know what I find.
