Had my completely standard FZS dynoed at 126 rear wheel bhp, then had Mike fit a Full Monty, both in early 2014.
Only just got around to having it dynoed with the Ivan's kit on and a MIVV exhaust with baffle out, but somewhat disappointed to see that it was only 128bhp (based upon 140 crank bhp less correction factor).
I'm guessing the exhaust alone should have given me that :-/
Got to go back to my dyno-man, to get a rear wheel print-out, so I can overlay and compare the shape of the graphs - maybe it's filled it out elsewhere on the curve???
For certain, the Ivan's kit has made the bike MUCH more controllable - probably worth it for that alone, but even the Ivan's website says I should be getting 135 - 140bhp.
SO.......going to book it in somewhere next month to check it out and see where my missing 10 horsepower are.
When I can find the dyno graphs, I'll post them up here, but something clearly isn't right.
