redd Posted April 11, 2008 Share Posted April 11, 2008 Not mine but m8s RD125LC. He's deciding to take test after 20yrs o me aggin him he decided to get 125 and ride this for six month, and take lessons and ride at the same time, fair do's... Problem. He managed to get the bike to run right after re-jetting and re-jet and ermmm re-jeting . And now has a leaking cylinder head gasket So he rang me the other nite and dreamt of fitting a Big Bore Kit while the head was off ( as you do ) So here is the Big question. Can you still buy Bore Kits for these? How Much? And where? I will happily pass on any info... Big Bore Kits, i remember my MB50 65cc Ortisa bore kit -60mph- at 16, sweet Link to comment Share on other sites More sharing options...
racerd Posted September 18, 2008 Share Posted September 18, 2008 you can get the standard 10w00 barrel liner taken out and get the barrel re linered to a bigger size then you need to get the cylinder head machined to match the bore size then get the squish re cut Link to comment Share on other sites More sharing options...
