I have a chance to pick up a 1999 CR125 in trade for helping out the owner with some work on his car. It is bone stock and looks pretty clean for the age. It will be ridden by my 15 yr old grandson. He is a great rider but grew up on 4 strokes riding mostly single track with a little desert thrown in here in Calif. Could this year Honda be made into a decent trail blaster? The price is good so can afford to add flywheel weight, suspension work and cylinder porting if the end product will work. Thanks in advance.
