I looked and can't find what I wanted.. Do I remember an issue with the CDI with an issue regarding charging or starting? I am just wondering now that I have the CDI and battery issues... I may be thinking about the 400ex I am not really sure.

 

I have the ron woods cdi and do not have either problem. I do not recall reading anything about it either.

 

Seems like IRONROD had a little starting and idling problem with his after he installed the 14:1 piston. I haven't had a problem with mine at 12.5:1.

 

yeah I've heard from several people that high compression ratios past 13:1 need retarded timing in the low rpms and the RW cdi is too advanced for them.

 

MudStud,

Ok man, here the scoop. There have been no issues with the Ron Wood Racing CDI with regards to working with the 11.5:1 piston. Certainly nothing regarding charging. However, I did have an issue with my old Ron Wood Racing CDI working with the 14:1 piston. The timing is simply too advanced at idle to run that piston well at idle RPM. I tried it and found that, even with the choke on, the motor would simply dead ping at idle. That's kind of scary if you think about it. I don't know if other people had any problem with the same combination - I dont know of anybody with the same combination either. I do know there has been no changes in the power curve for the Ron Wood Racing CDI since its inception. I replaced mine Ron Wood Racing CDI with the Vortex and now it just purrs at idle. Its important to note that the power curve I chose on the vortex is the most advanced curve - and it still purrs at idle.

Curves that are too advanced on the top end tend to be detriment to running well at idle.

 

Good, I am glade to hear it's all good. I was just making sure it was not my CDI that was causing my battery issues. I just bit the bullet and bought the PC545 dry cell. Thanks..
