I bought a old 750r that has been sitting for 4 or 5 years,as a project. I was getting ready to remove the back tire. got everything out of the way and started to lightly pound on the axle hoping it would slide out. but nope! hit it harder and harder and nothing! Im thinking who ever put the tire on last didnt lube the axle, but the wheel moves freely back and forth. but that dam axle wont budge, even with a sledge. any suggestions?
