For anyone else who needs to do this I have just asked on another forum about removing the rev limiter from the cdi pack on my motor.
( I have also asked all over the internet too, and a few local shops near me that re-map auto stuff).
I was about to let a local electrics bloke attack my spare cdo to get rid of it, he told me it will be easy once he got to the board ????

I have the cd3 stuff 1995 with the square cdi box.
so many people had told me this cannot be removed and that you need the older electrics blah blah blah.

well it appears that it can be done and very simply by cutting into the two orange wires from stator to the power pack.
the orange and orange with black get opened up and this takes away the rpm limiter and f.a.s.t (quick start) function.

I asked about it being switchable and the answer was yes.

so put the wires on a switch and you can start with F.A.S.T and then once warmed up and the timing drops simply turn it off and your unlimted for rpm.

this to me sounds a very simple process and saves changing out lots of expensive electrics and saves a lot of time and effort.
so all those with the oval port can now go and rev to the moon without costing a fortune.

this I have not yet tried but will be definitely giving it go over the next couple of weeks.

seems to good to be true, but have been assured by a nice clever man that it will work.

if anyone knows otherwise please let me know.
