Rob, please let us know how that works out. I was told by my wrench not to add any slip on until I put on a new fuel mgmt system (Super Sert, Power Commander whatever). The bike runs lean from the showroom and adding aftermarket slipons will make it run even more lean.....according to him.
No disrespect to your mechanic but I don't think anyone really can say one way or the other, me included of course, as to whats going to happen. I do have a close friend, who happens to me my wrench, who owns an 08 SE. He has run several experiments with a stock gauge attached (has it mounted inside the right leg fairing) and although the changes seem to do some good at first (making it richer, etc) the computer re figures or relearns or something and brings it right back around.
No that being said, I'm only talking about minor things not a fuel management system. I am sure a SERT or PC would (thats what they are made for) surely change things permanently. I just will not be the SERT Ginni pig. Others have already added just slip ons to the 09 110 engine, hopefully we can hear from them soon. The Ovals are definitely different. You cannot see all the way thru them (for back pressure) so it appears that they are made from a performance standpoint thus the price maybe.
I will keep you posted. If they come in this week I may have to lose on the steak dinner bet and try them out sooner than 5000 miles so I can let you know for sure. All in the name of science of course!
