My pre order cheque will be posted in the morning.

Luke, I saw on the tacho forum someone saying his 150 gave 9400 rpm with an APC 16x8 on 15% coolpower. That is what I got with my YS 120fz. So running a 17x8 and you should still be in the same ball park (around 8400 rpm is what I get).

The pipe would fit, it is the header that is the problem. Saito threads are different to OS and YS (I think), so difficult to get the headers. (I have looked!) You could ask Just Engines see if they do one but don't list it. Macs Muffler in the US do one, don't think available here though.
