hi, a friend asked me to built his engine of a yamaha dt 50 with a 55mm cylinder but everything was used from diferent bikes... i put a new piston and a new stroker crank but the cylinder was used and already ported by someone that loves to do holes...i haved checked everything(i think) but the bike doesn´t stop to four-stroke at midrange, on the low end it´s ok so it is when the bike enters in it´s power range... i thougt could be the exhaust port very close to the main tranfers(about 1 mm) so i epoxy the holes just to have sure but nothing...
someone could help me???
