I have a question about the stock DRR CDI.
When you pull the tab out, is it truly an unlimited CDI?
I'm having a top end speed issue, where I have 2 similar motors and gearing with the same rider and one bike is 6-8 seconds per lap slower than the other and I'm trying to diagnose it.
I've changed weights up to higher numbers, with no gain. I've changed to new fuel which gave me my biggest gain (which is where I am today with a 6-8 second deficit up from 10-12 second)
So considering that the 2 bikes are nearly identical in every way, I don't know where else to look... I was thinking maybe the stock CDI doesn't go up as high in RPM, I was thinking gearing (but don't think there is much that can be gained in gearing to make up the deficit), I was thinking clutching (with limited success), but I can't bring them anywhere near each other..
Any clues what to look at next?
