Kawasaki 440A snowmobile engine for my miniMax rather than a Rotax (I hate a dykes ring!).
However, this motor had 1 cylinder flaking; I found 2 new cylinders on EBAY for $190 total so I
am ready to go as soon as I can finish the plane.  The RV4 is on 'hold' until the knee mends and
I get the Max finished.     Ken Powell

Good Luck Ken, hope you heal well. The Electrofusion is a excellent process, too bad it really
isn't suited to our flat sideplate needs. Yamaha used a version of EF under license on some of the
TZ roadracer barrels so it must have been good. Almost any aluminum hardfacing system can have
flaking problems. I was told no matter how good the material, the area where the transition is
made is crucial.  Best wishes on the knee. My wife had a ACL graft-replacement, (thank you sports
medicine) and it really takes some time to recover. Don't push too hard too soon. Bill Jepson

Bill, why do you say the EF process " isn't suited for out flat side plate needs"? And what do you
mean when you say that "Almost any aluminum hardfacing system can have flaking problems.". and "I was
told the area where the transition is made is crucial" Are you refering to a spray on hard surfacing
process, such as det gun, or plasma spray? and Meaning that a flange or other raised portion is what
is crucial?
