[QUOTE="keithb7, post: 1119479, member: 58846"] 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. [/QUOTE]
