Sometimes thinks do not go as planed.
When you belief in something that hard, and your are convinced that others have it wrong it will take you some time to conceder that they are right.
It turns out that my own dyno was not set correct, re calculated my drum an that gave a massive drop in the measurements.
Of course not very nice for me to know, as I thought I was going the right way.
Thankfully don't have a company/ or a tuners name to keep high so a note on my site regarding the wrong setting should be enough.
But specially here I post a personal reaction, because they told me here over and over it is not making a +30HP and I did not belief it.
So my apologies for that.
The trough now is as followed.
After the new settings the HP's where dropping faster than I could think off.
But fair is fair, if this is what it should be, so be it.
The results so far
Stock the TZR125 (trackbike) has a 22,3HP at the rear wheel
And with all the mod's i did so far (shortened exhaust, 6 degree more advance, changed carb rubber, open carb) it produced 24,8HP rear wheel.
Currently have changed the head to a O-ring conversion, but need to dyno it first.
It drops the squish from a 1,3 to a 1mm and combustion volume to a 11,2cc
Hope this will bring me a 1,5 a 2 HP and it end up around 27HP
(not saying it will, but hope it does)
After this like to do some other steps but that would probably bring more in the mid section than on peek power
Will let you guys know
