Good question. I wasn't sure for a bit as it was like when I used to fly single engine planes over the Bass Strait - the engine would 'seem' to run rough once clear of the coast! I've checked it thoroughly and there is no sign of leakage and when I don't think about it, it's fine. The actual handling, which I guess makes a good acid test, is as good as I remember.
I can't tell you who did it as it was done through our local 'TCF Motorcycles' (for a lot cheaper than it would have been through Peter Stevens and Troy, the owner of TCF looks to find ways to keep MY costs down and end up with a better job). Troy can be called during normal hours on 5441 8177. The only hassle I had is it took about a week for them to take it out, send it down, get it back, refit it and test it. It took 6 weeks for whoever did the refurbishment to take it off the shelf and I doubt he would have done it then if I hadn't nudged TCF a bit.
Hope that's helpful.
