i took the bike for a ride with no tank and got on it with all i have and the shifting was no different using the horn button to shift. i do notice than every time i hit the button to shift the compresor come on for 3 to 4 sec a lot shorter than before and the compressor shut off till i changed gear again, i know that is common sence since i have no tank, with a tank i use to shift 3 gears before the compressor cut on but the copressor will stay on for atleast 10 to 13 seconds, once i get my hard starting problem solve, i will use the auto shifter with the rpm module to see how it goes. btw 2fast4u2c i just talkto you about the 24v mod and placed the order. that is why i need to remove that tank i never liked it any way. i think my air compressor and the 150 psi pressure switch will do the job. air lines are short and straight to the shifter, will post pictures tomorrow.
