Hi All,
I bought one of the Repsol Limited 4RTs, in that one there were Three Ristrictors in the Exhaust System, one at the exhaust port from the Motor one that is between the Header Pipe and the Muffler and one at the end of the Muffler. I've taken them all out, It Idles real low without a sound but really barks when you get it to almost full tap, I've found that in the airbox there is the flame arrester covering the airfilter, I've taken the gauze off the frame so it can breathe alot easier,
