Well, I dont want my post here to be a highjack..., but im gonna install my Rocket cdi in place of the lightening cdi and then install the lightening cdi in place of the stock cdi on another bike in place of the stock cdi unit.
I'm gonna kill two birds with one stone here by seeing if the rocket will give me same top speed and rpm as the lightening, and then Ill see if the lightening will give the same results or not on the other bike in place of stock unit.

What I may do also is put a stock unit in place of the rocket cdi after I see how it compares to the lightening, im figuring on trying all three units on the fastest bike to see if there is a noticeable difference in how it runs or what the top speed is between all of them on that bike, I will test each one on the exact stretch of road with absolutely nothing else being changed on the bike accept the cdi.

I think I already know what my results will be, but there isn't but one way I have to find out for sure and that is to switch between each one keeping all other things exactly the same and see what the results will be, im gonna be flat out straight up honest in everyway with my findings and than I will stand firm on my solid opinion about each one and if there is any "snake oil" in the claims of more power and better top speed that is said to be an advantage with the Rocket or the Lightening cdi's
I already know what happened when I used the original Jag type with retarded timing at upper rpm.... it was a dog.... lost 6-7 mph off top speed and it as I expected made no difference in engine vibes.... I always believed that claim was Bull Pucky anyway, timing wont counter the effects of a badly balanced and horribly untrue crankshaft.

Ok ill shut up with my semi hackjack post here.... and ill create a new thread with my test results when I get that little job done.

I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
