Rebuild the cylinder don't replace it unless absolutely necessary. If you are rebuilding it, have it replated NOT sleeved. Modern motorcycle engines have plated cylinders. The engine is engineered to run properly with a plated cylinder. Sleeving it will change how it runs dramatically, and not for the better. Do it right, replate it. Replace the piston, don't try to reuse high wear parts like pistons and rings. Good mechanics replace worn parts. If your bike is worth fixing, it's worth fixing right. Always use new gaskets. There is an old saying...there is no such thing as bad parts, only bad mechanics.
That's it for now. Taking the time to rebuild you bike correctly will make it perform better then someone that takes a brand new bike off the showroom floor and just races it. Next time we'll talk about how to make this freshened up racer look as good as it performs. |
