What is better the victory kingpin or the Harley Davidson Fatboy?

Answer 1

The rear motor mount is the same four bolt configuration but will not line up because the offset of the engine is different and part of the crankcase fouls the swingarm pivot. If you don't mind cutting your ironhead frame about then yes it can be done but it requires a fair bit of surgery. I decided to alter the engine to fit the frame instead.

Things to take into account

1/The evo motor is taller than the ironhead and the rear pot will not clear the frame

2/You can make offset rear motor mounts, it needs to go approx 10mm to the right as you sit on the bike for the l/h lower crankcase to clear the l/h lower frame rail

3/Part of the crankcase at the rear does not clear the swingarm pivot and will need milling for clearance

4/The front edge of the crankcase on the cam cover side may need slight clearancing to avoid frame down tube on right hand side

5/You will need to make one off front mount plates/top mount plates and front cylinder mount.

6/On mine rather than notch the frame I channelled the rear rocker cover to fit

7/ I had to make one off exhaust as the rear pipe fouled the oil tank and the front was on the frame

Basically lots of one off fabrication work, but it can be done
