Kawasaki in the 80s used what it called Electrofusion in its motocrosser bores; run a chromium wire 9into the aluminum bore and run a huge current through it, vaporizing the wire, which then plated the bore nicely. May still use this process. It IS reconditionable, I believe. More recently BMW was using a similar idea, Nikasil, for aluminum bores on its bikes. -- Andrew Grebneff 165 Evans St, Dunedin 9001, New Zealand <andrew.grebneff@stonebow.otago.ac.nz> Seashell, Macintosh, VW/Toyota van nut |
