CDI problems at high RPMs?
Posted: Sat Aug 30, 2008 7:02 pm
So i noted in anothe thread that i am having problems when i do a high speed run, once im pretty well flying.
It is very odd, once i get to about 60 (sometimes i can get up to 70,..) the bike will stop accelerating, and it is like i am pulling the brakes on and off, or as going from full throttle to no throttle instantly.
I can really only describe how it feels as like downshifting in a car just using the clutch. It will do it 2 or 3 times, then usualy it will let me cruise, but not accelerate much after that. But once i come to a stop i can do it all over again with no accel problems untill it 'brakes' again.
My only guess is that it has to be spark related, as theres no way that the fuel could just stop going in like that. it would at least sputter down.
I have a good spark plug, and a hi-energy coil from daywot. I get bright blue spark when i test it.
My question is, could the old original CDI box just not be able to produce spark at that high of RPMs?
Also, i know when i was taking the alternator type thing off of the crank i know that 2 of the wires going into the clip had about 1/3 of their metal strands broken. Could that be a possibility?
Let me know what you think.
