January 14, 201214 yr Hi It seems that the 4RT has a 3-way restriction to meet the European noise regulations. One in the intake between the trottle body and the cilinderhead, see yellow dot on bootom picture: My link There are also 2 ristrictions in the header exhaust pipe. The abbove ristrictions are easy to remove but i've read somewhere that there is also an electronic restriction/bypass. Is there somebody that knows how to "remove" the electronic restriction? I hope I can enjoy the full power of my 4RT soon
