Had the dealer do the power up on my new 310 before delivery and was pretty happy with bike. Went to clean air filter for first time and figured I would pull stack and check it out. Come to find out it was the plugged up stack. Cut end out as per threads found here and WOW what a difference. It is a completely different bike with more low end and a serious hit up top. Not sure why dealer didn't change and will ask next visit. It always had a flat spot at the upper end I wrote off as the way it was going to be. May need the map switch now to keep me out of trouble when needed. Any idea why a dealer would do everything else but not the stack?? Never rode it all plugged up and wonder how much it changed with partial powering up because opening up the stack was amazing.
