degreen cams means the orientation of the cams to the valve opening, both for intake and exhaust to specifications or to various specifications
and 3 A lighter flywheel means that you'll spin up rev faster, more quickly at the expense of some low end torque.

Another reason for switching to stick coils is eliminating the 20 something year old high tension leads. After I installed them, I found that the engine idled smother.
Setting the TPS to 500 ohms starts the advance sooner on opening the throttle. Worth doing as the engines run a bit better.

Calibrating the TPS is as standard maintenance item as changing spark plugs...

Be aware that if you fit this advancer like I have your engine will sound different.
...
I found out the hard way as this mod was done in conjunction with many others .
The change in sound was alarming, so I reinstalled the original which is different to the 4 degree and the engine sound returned to "normal"
...
I am used to it now and have experienced no problems over the last 18 months. Others on different forums have reported the same.
One thing for sure is that it livens the bike up very noticeably.
If I remember correctly mine is a factory pro one and my bike is an 05 model that is supposed to have a different advancer to earlier models but when you compare the standard advancer to the 4 degree the splines are different.
This has been debated many times, all I know is that the bike is stronger with the 4 degree in place.

1. What do you mean by "the hard way"?
2. In how far the sound is different?
3. liven up noticably means more pull with the same gas? (This is what advance should do)
4. Where did you read about different advance of later VTRs (Facelift 1 + 2??) I cant find any validated info about that, only speculation.
@all: Can anyone give proof of a VTR with +4 advance rotor installed without piston dmg/knocking in the long run?
I ask, beacause I use an Ignitech CDI with which I can set evry Ignition angle seperatly (derived from TPS and RPM).
