I'm real interested in the 45 Magnum conversion. Looking around using the search feature, it doesn't appear like a lot of us have attempted this one but maybe some Lurkers or new people will chime in.
Here's what I know so far:
1) It's an Ironhead Sportster top end on a Harley-Davidson W-series bottom. The conversion involves machine work and heli-arc welding.
2) It ends up producing a very light bike.
3) The Sportster top end tends to produce more power than the W bottom and early 3-speed can handle.
Here's what I like to know:
1) How exactly is it done? Clearly it's not a bolt-together, but is it something not to be attempted without years of welding and machining experience?
2) What capacity results? Maybe the same as the Sportster used?
3) Is there any way to beef the 45 bottom end so it will stand up to the power?
4) Are there any transmission options beyond the OE 3-speed? It would be nice to run a modern BT trans like the 5-in-a-4-kicker available now.
Hopefully this will spawn some interesting discussion. Thanks.
