I'm choosing the Gas Bike 'Super Charge' CDI for the race on Saturday. Many of them were very close in performance, but this one was just a hair faster & ran a few degrees cooler.' Venice also posted that the timing at top rpm is more retarded than the Jaguar CDI is. I have two thoughts on that: 1. He didn't make use of the adjustability of the Jaguar CDI because he talked of it like it was set and not adjustable. (It doesn't arrive with the most retarded timing.) 2. More retarded lets the engine wind out farther (more speed/rpm) but at the expense of less acceleration and less grunt going up hills. The curves on the Jaguar CDI are all centered around what normal performance motorcycle CDIs have, not too advanced or retarded. Just right for good acceleration and good speed. Unfortunately Venice picked the CDI that gave the fastest speed at the expense of the best acceleration. But at least he admitted he is a rookie racer. Jaguar himself is not a rookie and definitely knows more on the subject than anyone I've come across and all his competitor CDI makers. Timing differences of 5 degrees makes little noticeable difference. Let's assume the difference is 5% of 2hp which is .1hp. Who in the world can feel the difference of .1 hp? Over the last year or so the Jaguar competitors have made their timing curves more retarded to be in competition with the Jaguar Performance CDI, and some even more retarded. Looking at all of them I still think the Jaguar is the best because of the quality components used which guarantees reliability, the most correct timing curve which is also adjustable, the documentation (no one else posts the graph of their CDIs ignition timing from idle to 10,000 RPM), and the customer support. The Jaguar CDI is made to be compatible with high output coils like those from a Honda CR from any CR motocross bikes so you can get the best spark using it. So you can just buy the Jaguar Performance CDI by itself and order a coil from E-Bay or somewhere else. Also it is the only one that automatically adjusts timing depending on the temperature. It's slightly more retarded in the summer and slightly more advanced in the winter.
