thats a nicely kept machine Paddo.
Did you do a baseline run before the new Tsukigi on the same dyno?
It is all about gains from a baseline on the same dyno, every dyno is calibrated differently to suit the operator depending on how honest they are

and changes again depending on atmosphere and other variables, that's my understanding.
I have a chart done in Sydney by the previous owner on my 2006 ZX12R @ 188rwhp, local dyno read the same bike @ 167rwhp (i think) and my 2011 ZX10R at 151rwhp /pcv+ akra, so you cant rely or compare between different dyno's.
