Hey people,i just got back from germany (i live in kent) and over there, there is loads of XLR (wot ive got) and XR´s.There is a black box with three wires coming out of it. Green, yellow and red. CUT THE YELLOW WIRE!Basically this derestricts the CDI unit and get a Predator exhaust and cut the top of the airbox. I took my mine after fiddling with the jetting and mixture and now it has 22bhp and wheelies (even with a heavy front end) in first and second it has so much torque for a 125!It sounds better, and since it is economical anyway it still does at least 120 miles before you switch to reserve! Basically teh CDi apparently on the XR and XLR cuts out very fast every other spark in 3rd gear upwards! Hope this helps, email me if you want help
