I just did a compression test on my stock 93 with 50000 miles. With engine around air temp 65-70 degrees F. From front left counter clockwise. 30,110,70,110. After warm up all cylinders right around 120. I re-checked the low cold numbers several times removing and rethreading the test hose. The reason for the test is that it doesn’t have its normal arm stretching pull between 4000 rpm and redline. If I back off the throttle a little it pulls a bit more but surges like it wants to go but never really does. This bike hasn’t been ridden a lot the last few years but it idles well and I have cleaned the carbs and synced them recently. I can hear the v-boost cycle when I turn the key on. At lower rpms when you roll the throttle on about halfway it seems right. Also front left spark plug looked lighter colored than the rest. What should I make of this?
