[QUOTE="darringer, post: 1216460, member: 26849"] If the cylinder has aluminum from the piston on the Nikasil, it can be removed with Muriatic acid. It won't hurt the plating. Just be careful not to get it on the rest of the cylinder, as it eats up the aluminum rather quickly. Afterwards, wash the cylinder with soap and water thoroughly. Even if there are small bare spots in the plating, the cylinder is still useable. Unless there are deep scratches, or flaking Nikasil as stated above. A friend of mine ran an SST on his '02CR250 when I had my '02CR250 with the Fatty. Everything else was stock. The only difference I noticed between the two bikes was his with the SST had just a bit more pull at the very top. Bottom and midrange was about the same. [/QUOTE]
