keithb7 said:I have a 1993 CR250 with an FMF Fatty pipe and a Core II silencer.
It makes good power all over. I can pull way past 60, and there is lots of power on the top end. I generally ride in the mid's and don't use the top end too much, but is certainly is there if I need it. I love the Fatty pipe. The CDI is programed I believe to curve the timing as the engine RPM's increase. The timing has to advance as the engine rev's. Remember in the old days, car distributors had weights for mechanical advance. Then we went to vaccum advance, then finally to a pointess CDI ignition system. Our dirt-bikes CDI's advance the timing as the PRM's increase. If it does not advance, the power falls flat on it's face.
This could very well be your problem. Do you have access to another CDI to perform a test?
Based on your findings, and new parts, I'd just about bet the farm on the CDI.

keithb7 said:Well, I guess you are little to far away to borrow my CDI. I have been to Orange County, it takes about 25hrs to drive there from here. Good luck.
keithb7 said:I don't think there is a way to test a CDI. You can check continuity, but that's not going to tell you what you already know. Continuity will only tell you if it works, like a light switch...On or of. We know it works on or off. We just don't know if it is capable of adjusting the timing as RPM's increase. I don't believe there is a way to test without some crazy priced special tool from the manufcturer, snap-on etc.. I am pretty sure you can find a cheap CDI on E - B A Y.
cnielse5 said:Uh, dude did you notice that there was an eletrical plug on that carb? did you have any thing to plug into it?
cnielse5 said:If it is a true 99 carb then it will have an electrical connection. starting in 97 the carb has an electrical solenoid that opens another fuel jet in the carb. The solenoid opens from about 1/4 throttle to full throttle.
