    First Dyno run, standard bike

    My first Dyno run, standard bike 2,800 miles on the clock.
    I will post an update when i have fitted the Mivv oval carbon exhaust I've just ordered, hopefully i will do a run on the Dyno with and without the DB killer to see what difference there is.First Dyno run, standard bike-mt-07-1st-dyno-run-jpg

    Perfect fueling - don't forget to check the fueling and not just the power on the other dyno runs - but whoever does the runs for you should point out any problems

    Looks like Yamaha got the fueling pretty much spot on straight out of the box. I've got to wait 2 weeks for the Mivv pipe to turn up before I can fit it and run it up on the Dyno again. (It's coming from Italy).

    Here was my dyno run with the factory Akrapovic - both with and without the db killer.

    Without the db killer it has 2 more bhp but note how lean it is.

    Will be looking into ways of sorting this that are cheaper than a Power Commander.

    I just had a look at the two different dynos and made some comparisons.

    Looks like
    Stock bike 65.75hp @~9000rpm, 44.6ft.lbs @~6500rpm
    Akra with DB 67.5hp @9031rpm, 44.9ft.lbs @6571rpm
    Akra no DB 69.4 @9059rpm, 46.3ft.lbs @ 6642rpm

    @Pog.
    When you get the Mivv runs done, try to get a chart that shows all trends, then its easier to see where in the rev band the changes are.

    guess that means.
    +2hp and virtually no torque gain from stock to Akra. A/F spot on
    +2hp and ~1,5ft.lbs torque from Akra to Akra without DB. A/F looks good
    +4hp and ~2ft.lbs torque from stock to Akra without DB. A/F not good, expect to see more gain when the A/F is corrected

    Nice to see a run at stock to compare manufacturer figures to real world (Rear tyre) figures

    VIDEO OF REMAP (baffle in ) it's a live map that adjusts to any changes made ie stage 2 air filter ,
    or removing the baffle it gives the optimal running for each change made ie greater increase in BHP and torque.

    Finally got on the Dyno again with the Mivv oval carbon fitted. I had to use a different Dyno from the one i used at the start of this thread so i cannot overlay my original standard run.
    First Dyno run, standard bike-power-jpg
    The red line is with both db killers fitted, the black line is with the db killer removed from the end of the silencer.
    First Dyno run, standard bike-torque-jpg
    The red line is with both db killers fitted, the black line is with the db killer removed from the end of the silencer.
    The max power has gone from a standard 65.75 Bhp up to 69.2 Bhp and the Torque has gone from a standard 44.6 ft.lbs up to 47.5 ft.lbs.
    The fuelling seems better with the db killer out with it in it runs slightly rich.
    The ecu is standard spec, (not flashed).

    Hasn't anybody noticed how ALL of these AFR maps shows the ratio getting ridiculously rich from 9000 to 9500? That's the way to lose HP where you could use in ( on a track anyway). Are non of these PCV's or reflashed. I just checked my post reflash post induction restriction removal AFR graph and it's the same. There is more useable HP lurking in those engines unless there is a port , airflow restriction, camming problem, air resonance, valve spring, problem waiting to be fixed. Something is still stopping the air getting i at high revs.
