RPM hang/rise after shift
This is a problem I've had for a while and just haven't gotten around to fixing it. The rpms will hang and even rise after shifting. Doesn't seem to matter at what rpm I shift it will hang a little. I even have a lightweight fly so if anything my rpms should fall pretty quick. The odd thing is, some days it won't do it. But for the majority of the time it does.
An easy example of this is if I driving in 2nd or 3rd and just press in the clutch. The rpms will hang and slowly fall as if I still held the gas in. I've made sure it's not the throttle, cable, or dash pot doing it.
