The summer is gone and i've made some minor changes.
I gave away my akrapovic exhaust and i've replaced them with an other couple totally hand maded by me.
I needed more torgue at low end rpm and the akrapovic didn't have enough backpressure for this job.
So i've installed back the catalytic converter and a new pair of cans with a brand new Y pipe for them.
The Y pipe is builded to seperate the exhaust fumes equal to each can and thats the basic difference with akrapovic or two brothers or even worst laser Y pipes.
Unfortunatelly i had to sucriface my number plate holder for a couple of days because i didn't have enough material to build a brand new suitable bracket.
These are the cans.
This is my new Y pipe.
And here they are fitted on the bike.
The wideband analysis showed up that the AFR ratio is below 13,9 in any rpm range but it needs some adjustments.
I want it leaner at low rpms.
The target is to create a map that uses lean ratio at low rpms (1200-5500) for fuel economy in the city , a little bit richer at mid range rpms (5500-8300) and rich at high range (8300 to top) for performance.
By this way i believe that the autonomy in the city and everyday use will be increased and the performance above mid range will be increased too.
I think its a good deal!
