the real air restrictions 

Now that you found the restriction are you putting the stone guards back in the air intake? Or you reckon that was also restricting the air flow?

Did it feel/runs better? I'm in the U.S. and I'm thinking of doing the same thing

nice investigation process here mate. awesome to see that you've finally found where it is. did you get it derestricted at the end or you've left it stock?

My bike is restricted and does not have those ... only the electric one and if i go ride de-restricted it stops at 10k rpm ...
