I take it you do need the keys if you want to advance or retard

As I understand it there's pros and cons for the different pulleys. The stock adjustable 620 ones are easier* (* = relative term) to alter and you don't need to buy offset keys, but the non-adjustable later 600/750 ones are lighter, which is supposed to be better.

I couldn't decide which is best so I have one of each........:lol:

This is all very entertaining -) but no one has stated what the settings we are seeking actually are ie max opening of inlet at ? degrees

Please explain,the suspense is killing me

If you had the optimum settings & a super powerfull engine how many peps might you tell?.Trial,time,& lots of track time is the answer i think.

If you dont know either just say so x

makes c**k all difference. Just ride smoother and brake later. ;)

Whats an optimum setting?? I time mine differently to the well published settings. Other people may also do theirs differently also. As a start do it to the book but make sure both cylinders are the same, as often they are not.

No one is going to pass on their own settings which work for them and has taken seasons to develop. :D :eek:

:lol: i'm not daft enough to think it will make me any faster

there's a book for this. :lol:

must learn to read......
