I don't mean to disrespect your project but the idea of flying behind
a Harley-Davidson engine-I owned a couple of them before yuppies made
them expensive, they were the most cantankerous, oil-leaking things
around. With only two cylinders don't you have torsional vibration
problems out the wazoo?


The Harley Evolution engine is quite dependable and doesn't leak oil. It
runs 10 or so degrees cooler than the shovelhead engine. Having owned and
ridden a brand new '89 H-D Softtail Heritage, and now owning a shovelhead
from the 70's and a panhead from the 60's I can vouch for the durable,
dependable Evo engines.

BTW, I have no interest in converting H-D engines to aircraft use and don't
know anyone who is doing it. I have visited a H-D to aircraft conversion
website once, probably 6 months ago. I'm strictly a Continental and
Lycoming kind of a guy.
