Question about 2002 Honda CR 125 R
Posted by Anonymous on
120 psi means you need top end( should be around 160psi) if you can feel the score marks with your finger you will have to have the cylinder bored and install a over-sized piston kit,if you cant feel them than you can have it honed.....now the stuck power valve is why you didn't have any power,take them out and clean all the carbon deposits off them and reinstall, pay close attention to how they come out so you can put them back the same way...if you have a manual you can check the adjustment specs on them also.....now on to the crank,the first indication of bad crank seals or bearings is losing your trany fluid,if you don't feel any unusual vibration or hear any unusual whining or have a large amount of lost trany fluid your probably OK with the crank.......yz-maniac
