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 :)
