Have had airshifter on my bike for 3rd season. Last season was having issues getting it to shift from 3 to 4 adjusted kill time worked some time others didn't .
This year testing, can not get to shift at all ,,,,,,,,,,,except and only at low RPM ,,,,,,tried all kill times. The air pressure is fine the ram works I can feel the relay in the kill box clicking when I hit the botton. At idle I hear the engine kill , but if I rev to 3k or above I can not hear any kill at all.
Checked all wiring everything in tact.
It is a MPS box or clone.
Any help would be appreciated, I forgot how to foot shift at the track LOL.
