having problems with my airshifter changed everything but the kill box (MPS). It will shift from 1st to 2nd and 2nd to 3rd but hesitate 3rd to 4th. Do anybody have any suggestions?

air pressure? are you using air or c02? is your supply air full, or lasting into your run? are there any leaks?

ok, it sounds to me like the shift is happening to fast. the bike isnt having enough time to remove the pressure from the gear set to get the shift in, i would try backing down the pressure a bit and see if that works. thats really the only thing i can think of. if that doesnt work, you might need to have it looked at.

The problem isn't too much air. The question is where did you mount your air solenoid. It's only supposed to be a maximum of 15 inches from your ram. A nice way to do it is to mount it right on the ram.

i keep my pressure to the shift ram at 120psi. but i was having a porblem the other day with a shady bracket i had picked up. the bike wouldnt shift certain gears certain times. the bracket wasnt strong enough and would flex. when you would shift it the ram instead of just pushing foward to shift, it was pushing backwards bending the bracket at the same time, so the shifter would touch the next gear and once you let go of the button. you were in no mans land. check your main bracket and X2 on what BNL said about keeping the on/off solenoid close or on the ram.:beer:

does it do this every time exactly the same way? the reason i ask is because it could be the shift ram binding. depending on how you have it mounted you may need to allow some play for the shift ram so it can wiggle a little and shift smoothly.

This is the new ram
You've got it a little close to the end of the shifter. It might be binding. Put the back wheel on a stand so the wheel is off the ground. Take the pin out the ram to the shifter. Hold 1 hand on the shifter, and use the other to spin the back wheel and shift it up into 2nd and hold it up there. Now meanwhile you're holding up the shifter, put the ram on the shifter to see if it is lined up with the hole and is moving freely.
