We have talked on the x before about all the differences in the stock ignition system for the 760 yamahas as compared to the 701 ignitions. I/we know that the back cylinder has a slightly more retard ignition timing then the front. Also that can be eliminated easily by removing the indicator on the flywheel that the stator uses to tell the cdi which cylinder it is firing. None of the ignition components can be mixed with the 701 systems (other then the coil and e box cover).
What i cant ever seem to find is the actual ignition curve or even a clue to what max advance is or what degrees before tdc the curve ends at when it hits the limiter. I have a gut feeling this ignition may retard back at high rpm more then the 701. Which would make it a cheap alternative to expensive ignition systems when running big pistons and high compression.
The flywheel is heavy but can be lightened to the same weight as stock 61x. In my opinion thats light enough to not have the weight counted as a factor in whether this ignition system would perform well enough for freeride application.
Anyone got any info or any old literature to give me a clue??
