Sorry for the late reply guys - been offline for a long while. The Ohlins are a huge improvement, They're HD Fatboy fit but you need to do some work to get them to fit. I had to make up spigot adapters to fit over the original mounts - this is also needed to move the shock outboard so the reservoir would clear the frame. Got some titanium bar turned down at work to suit. I'm lucky in that I used to have access to some pretty advanced machining for a few tins of beer.
