05' M7 Problems

[catrider5064]

I have a 2005 M7 with around 1000 miles, I was riding the other day when I pinned it and the check engine light started flashing and the sled started to bog down and somewhat cut out. I have a D&D big dog barker can on the sled and a Attitude control box, I unhooked the control box to see if that would help and it did nothing. This problem typically only happens when I pin it and sometimes when I get to around 7000 RPM's. All thoughts will help, Thanks ahead of time.

Sounds like a power valve sticking issue. Either you need to just clean your power valves, or your servo is not working. The valves should open around 6800 rpm but you can still usually wrap the sled up to 7000 or 7200 if they don't. This will also make your sled run hot which will make the check engine light flash.

Clean the valves, then rev the sled up on a stand. The servo should rotate at about 6800, if not you know that your servo is dying.
