Question on rejetting after an exhaust swap
 

My Two Brothers exhaust is pretty much toast (cracked carbon fiber). User captainchaos said he would swap my old Two Brothers for a set of the stock pipes. My question: what is the likelihood that the previous owner that put the Two Brothers on had the bike rejetted? IS it common to rejet after swapping OEM for aftermarket slip-ons? It runs fine as it is (no popping, no weak spots in the rpm curve) but I wonder if I will have to do any tuning after putting on the OEM pipes. Any thoughts?

The only way to know is to open up the carbs and look yourself

+1^, I didnt know I had a Jet Kit till I opened the carbs just this week. Go figure. Im the 3rd owner of my bike.
