Bottom End Bog 2008 M8

[Cowboyup083]

I have a bottom end bog on 2008 M8 i have just over 2000 miles on the machine and the engine and clutch is stock other then i change the weight to 77 grams to ride around home.

I have noticed that I am burning alot more oil then i was last season. I am wondering what can be the cause of this? Does the APV need to be clean?

I one thing i did notice was when i had the 73 g weights in for the mountains it did not seem to have the bottom end bog.

If any buddy has any ideas of why there would be a bottom end bog that would help me out that would be great

Bottom end bog is between 4500 rpm - 5400 rpm then the machine is fine just wondering what could be the issue with it.
