Hi,
Just done a top end rebuild on my cr250 2002. Only done it as piston and rings had served their time,bike was running fine. Ive used a wiseco piston and rings.run them both in but bogs out at low revs.plug is very oily.any suggestions please need to get it ready for a track day this weekend. -
Did you get this fixed? YOu sure the piston is in the right way? Arrow towards the exhaust port?

just changed the spark plug and a small adjustment on the air screw as it was running rich. she went like a beast :)
