IMPORTANT NOTE:
Remember!
This is an R1 motor. Ignition advancers are not recommended unless you have significantly raised the compression!

From the Ivans kit instructions, any ideas why?

I had read the same thing before. But then it was pointed out to me most Americans tend to run cars/bikes etc. on lower grade fuel (85 Ron) Ours is 95 Ron as standard. I run mine on Shell V-power (claimed to be 99 Ron) so this allows for a more reliable detonation and less pinking. As such over here we can run an ignition advancer with little issues and in truth I do. mine is a nicer bike to ride under 5000rpm in everyday traffic.
I know there was a time when people were getting the file out and modifying their own lol

Thats temptation enough for me, I can always run on avgas 100ll if needed. 
I'm tempted with the 4 degree thing off ebay for £14 just to keep the original as standard in case, anything that makes for an easier ride works for me.

My thou has Ivans kit, pipercross air filer and a straight through end can.. would be interesting to see feedback of the 4 degree advancer on a more stock bike (if yours is of course)
