Today the weather was not too bad with 5°C and almost no rain. So I did a little 60 Km ride to test everything...
There is absolutely no doubt about the fact that the ACE Airbox brings much wanted power.
There is not so much torque around 3500/4000 but from 4500 to 5500 the engine now flies when before it was totally dead
I tried to push up to 6K RPM in 3rd and 4th but it useless. The engine loses all steam past 5.5K.
But it's so much better than before to feel the little engine galloping from 4500 RPM
And the speed ?... 150 kph at the GPS, almost 160 kph on the clock (almost !) at close to 5.5K RPM

(and a pause to heat up my hands !)
Now some checks. The spark plug still looks OK ?
The velocity stack is still in place.
The look of the top of the piston (the picture quality is very bad). Intake up, exhaust down, spark plug on the right.
Now I check the map computed from the previous trims and today's trims. No adjust over the -/+20 limit I set so it is correct.
For gizzo, here is my Target AFR map and my ignition map :
(I forgot some values in the 20% column !)
Next steps will be the test of otto's velocity stack and next, hopefully, the installation of Hitchcocks performance cams !
Maybe I will try to have a dyno session before installing the cams...
