The seller said the timing was advanced 4 degrees. But I do have a question on that as well. On my YFZ I put a Dyna CDI on and advanced the timing 4 degrees. So if the timing is already advanced (Mechanically) on the banshee is there any benefit of running an aftermarket CDI or should I keep the stock one?

if you put an after market cdi on it you will have to retard the timing plate back to 0. An after market CDI will advance the timing to much and it will run like S$%t. I tryed to put one on mine with my timing set at 4deg and it cut out real bad when you would try to give it some throttle.

i have been told that if you have over 160 psi that you need atleast 100 octane.

That's a good place to start when not considering alot of other factors. You'll be safe with that assumption

Ok here is some new info on the motor.

 

Weisco Hot Rod crank 4MM strocker with superlight pistons.

180PSI on the right and 182PSI on the left.

 

I guess now I know why he was running straight 111 octane.

 

He did mention that he retarded the timing 4 degees not advance it. Can anybody tell me the reasoning behind retarding your timing?

i don't know what i'm basing my oppinion on but that seems high (180psi) is that with stock head? because i've got the same crank and mine was 152 psi on both, but that was before i evan started it after rebuilding it would that make a differance?? like the rings not being seated yet?? i don't really know i'm still new to 2-strokes
