Looking at the possability of a new cdi I got to thinking:

With a new cdi the holeshot modules would not be needed.
Unlimiter would not be needed.
Cams with the timing advanced 10 deg would need to be changed back to stock timing.
Advanced timing timing keys would need to be removed.
Jetting would probably need to be changed again.
No change in exhaust except I may go with full system.

If I have made a mistake in my assumptions please post. I am just wondering. I was looking at changing cams, was going to order Tomorrow now I think I'll wait and see what we come up with.

 

Dan,
I believe everything you said above is correct EXCEPT that there's no need to reset the cams back to the original position if you've already advanced them 10 degrees. Also, I don't think you will need to rejet...but that one is just a guess.

Anyone out there agree/disagree with my thoughts here?

depends on which cdi some like vortex cdi will retard/advance your timing may not be good to have it advanced 10 and also have an adjustable cdi

 

the stock timing of the cams is a way the top end power is limited IF you have RETARDED the cams 10deg do not return them to stock unless you want LESS power
the rest looks right

 

retarding gives you lowend power whileadvancing is for topend power i run mine straight up to have both

 

not for cam timing retarded is for top end power[ p650-p700 only]
the cams come advanced 10deg
by retarding them 10deg they are stright up

 

I have my name on the new dyna, and my bike is stck right now with 138/142 mains with the CDI will I need to go 140/145??????

 

The reason I would think that you would need to go back to stock timing would is that if the cdi will correct the timing that was factory de-tuned why would you advance the timing another 10 deg. If the cdi is programable or adjustable then this would not be a problem. Advancing the timing too much will create heat by holding the detonation time too much. My thinging may be off due to this is not a V-8. I would like to degree a cam or two just to see.

 

the new cdi will fix the ignition timing
not the cam timing
