Hi all, i have just bought one of these missiles after riding a ZZr1100 around for a few years and wow what a difference.
it has a aftermarket 4into1 titanium akrapovic exhaust fitted, and i have noticed a small build up of black soot inside the outlet. there is no power commander fitted so im not to sure if its running rich or lean has anyone any ideas/solution can these be remapped ?

They run pretty rich from the factory. You can have it re-mapped if you like to save a little MPG.

If it hasn't been re-mapped when they installed the pipes, it can still be running rich from the factory map still.
