I have a 1987 xr600r that I have completely rebuilt. I want to know what break in method you guys use. Do you use the manual recommended slow method or do you use the MotoMan method, running it hard to initially seal the rings? If you use the run it hard method, do you think it would be o.k for me to do this on a 20 year old bike? FYI I have a new connecting rod, piston, rings, cylinder bore, camshaft, etc. All suggestions would be appreciated. Thanks in advance.
