Well I went long and hard looking for answers and no one really had a good answer for me.
What I did was bought a set of slotted cam gears from Graves and started playing.
Factory cam timing for the 07 R6 is as follows;
Intake open btdc is 39 deg
Intake close abdc is 65 deg
Exhaust open bbdc is 63 deg
Exhaust close atdc is 25 deg
These numbers alone can be hard to come by so keep them safe.
On the 2008 R6 they did change the Exhaust open to 64 deg and close to 24 deg but I did not use those numbers.
What I suggest is playing with the timing, it is really a rider preferred number and if you have a dyno it helps out a lot also, if not just keep trying until it feels right for you.
Just setting the timing to factory can be an improvement, remember that even though these specs are what they should be at, motors are made by machines and cam gears and chains are set in the motors with machines that do not have a very consistent way to make sure that all the specs and clearances are perfect so the cam timing can be off and setting them right can be a big improvement and worth the time just setting them straight.
P.s. if you need any help with how to degree the cams let me know do not atempt to do it without knowing what the steps are and how to get propper techincs done right.
Just in case
BTDC means before top dead center
ABDC means after bottom dead center
BBDC means before bottom dead center
ATDC means after bottom dead center
Hope this helps if you need more info let me know I will try to help.
Also I will revive the thread and repost this message there for you.
