I have a question regarding my 440 MXZX. I was testing it on the lake the other day and noticed the motor was pulsating at around 8300-8600 rpms. If I backed off the throttle, it would actually pull a bit more than WO. It almost acts as though there is a rev limiter but it doesn't seem so pronounced. My top speed was 73 on the GPS.
I did a plug check and found that they were running good. (switched plugs also) Fuel looked good. Adjusted the floats just to make sure. Stock jetting running in 40 degree temps.
My clutches were all cleaned prior to testing. My secondary was shifting out but my primary was about 1.25-1.5 inches from full shift. I am running 293x ramps, 250-380 spring, tested with several weights from 10.7 gram pins to 16.3 gram pins. Secondary running Dalton 44-40, Beige spring, B-6. I also ran 296 ramps with 10 gram pins and 230-350 primary with similar secondary settings with same results.
Any suggestions??? CDI? Coil?? Wires???
