timing question

[nlvredneck]

i'm thinking of doing the advance key mod, but if i also do a cam and cdi is that going to be to much timing? should i just do the key and not the cdi or vise versa?

Personally I'd only do one, and the CDI will give you more top speed with the extra RPM's.

Just MO

I would do the mod, I have had it on my bike for nearly 3 years now and it is a great mod. I also have a CDI/ Rev-Box and have no problems because 90% of CDI's just raise the rev limiter about 1000-1500 RPM's and do not effect timing. I also have a Hotcam Stage II cam, I did not advance the timing though the cam. So CDI and Timing Advance would be definate the cam is up to you.

cool, hey there 400ss, which cdi do you recommend? and do you know if i go to a 10.1 piston will i still be able to run pump premium?

11:1 and under can be ran on pump gas. ;)
