Looks cool. Can you write details of the mods?
It looks like you have changed cam heads. Also clutch slave lever has changed.
Ignition lock replacement also looks nice.
What about the top yoke, which brand is it?
Also levers look different.

2003 YZF-R6 cylinder head
2005 YZF-R6 Throttle
2004 YZF-R6 YEC Racing ECU
I spent many years in integrating
Has been constantly in the conversion

Is it direct fit with changing ecu, and throttle body and cylinder head?
Did you also change cylinder gasket with thinner R6 gasket?
How did it feel after all?

I use the YEC R6 line to make changes
The cylinder head throttle is mounted directly
The gasket uses the R6 standard specification
Power output 123PS / 10832RPM Torque 8.14KG-M / 10832RPM

How does it feel in low and mid rpm? (2000-6000)
Does it have more torque or low torque in low rpm?
I always wanted more torque in low rpm, some riders changed cams with R6 cams but it didn't afffect low and mid rpm torque.
You've changed also throttle bodies, it would make a huge difference, by the way how did you fit it under the fuel tank? Is it direct fit?

Fazil, you don't have to swap heads, just the valve cover and cams. Basically you need the cam position sensor for that ecu and COP (coil over plug) setup to work. The fuel pumps pressure regulator is 46psi so you need that too with the return style pump IIRC, so the extra fitting is needed too for fuel return. It snaps into pump body.
OP that is a lot of work! Good job! Hopefully the parts were cheap and runs well at all speeds!

My torque from 4500rpm to 15500rpm did not stop
These jobs are not easy
Increase the low speed torque ignition signal +3°
The clutch spring uses 03-05R6

YES You are right
As time permits, can post the power output curve and fuel ratio???
It looks like a port match and polish. The exhaust was done too, yes? As for the YEC harness, does that allow more access the fueling and timing features of the ECU or does this ECU offer that?
Did you buy a wrecked R6 for this swap?
Thanks for the info!

In 2013 no horsepower test was used
25 pages begin to describe in detail

A silly abstract question. Can all four COPs be removed and installed without dropping the engine?
I'm guessing you have to remove the battery and rubber mat but maybe not??
Thanks in advance!

Nadda.... to take the head off, valve cover goes first.
So, can R6 coil packs be removed and installed without taking engine apart?
