I just purchased a 1973 Honda CB 175 did not know much about the bike, just found out that it has a 1985 CB 250 or Honda Rebel motor, wanted to know if I could maybe fit 350 cc or 360 cc Cylinders and pistons on top of my 250? looking for a little more power, I'm going to rebuild the motor so I wanted to find out and get the parts beforehand. Thanks in advance, I will post pictures soon.
