M7 High Altitude Bog

[SchmidtheadM7]

My 2005 EFI M7 has a problem when I get to higher altitudes. It max's it's revs around 5500-6000, but when I'm back down low it'll rev to the moon. I've replaced the clutch spring, and cleaned the clutch but it still does it. Any suggestions?

did you change the weights when you went to the high altitude?

Have to change weights but also check the plastic tube coming off your ecm and make sure it is routed corectly and not plugged up.

It starts to bog at only approx. 3000Ft, do you think that the weights would still be a problem at that low?
