4 degree ignition advancer are their worth fitting?

[Ricky]

I have has a few problems starting the FZS, properly more down to me than the bike. I have been told the advancer might help, and it would hopefully help the midrange. I find when I want to over  take a car I have to go down a lot of gears, and than it still feels a bit flat.I am used to torkey twins and a GSXR 750, so may be asking to much of the Fzs.
I am hopeing to get the bike Ivanised in the spring, so do Ivansing and advancer go together, or should I just wait till the spring?
