davey 123 Posted September 30, 2010 Share Posted September 30, 2010 hi all im a newbie. does anyone out there know how to derestrict a tzr125 (93)belgrada. i live in france and bought it here and its a 4fl model. i also at the moment have a missfire over 8000 rpm in 4, 5 6 th. im have just had a new piston and the bore replated but it had this stutter or missfire before. i was thinking as i dont know the history of this bike that maybe jetting could be a problem ,, what is the standard size i should be looking for . i have read a few threads explaining about the 2 wires that are not connected and need to be earthed ,, does this apply to my bike to derestrict it The sevo when the ignition is turned on does 3 sweeps ,am i correct in asuming that it is resricted . the bike will do about 75 mph on the flat and about 85 down hill. any info on these matters would be much appreciated Dave Link to comment Share on other sites More sharing options...
