Hi all,
So I went and bought a ram-air intake system for my rocket. Fuel gauge worked fine before installation. Installed the new intake and EVERYTHING is reconnected. Turned it on and did the idle tune as the instructions said. The bike at the time had half a tank left so it looked and sounded fine. Rode it for a couple of days till gas light came on and there was one bar left on the gauge. Filled it up and the gaslight went off but fuel gauge stayed at 1 bar. Eventually, that 1 bar went away and now every time I refill the bar stays empty. I don't think its the float cause the gas light comes on when I'm low.

What do you guys think? Trying to not take it to the shop for something that's just a minor annoyance.

Thank you.
 
I have found that after I have disconnected the battery the fuel gauge and low fuel indicator light and the distance left calculator takes a two or three tank fills to adjust and even then it’s not very accurate.

You say you installed a ram air system? as in forced induction, what exhaust are you using???????

RAM-AIR intake kit from the ramair website. I've got a supertrapp tunable exhaust with I think 10 disks on it and the open end cap. Also, a PCV and dyno tuned.
I'm sitting about 140 hp to the tire and 151 ft. lbs of torque.
 
sounds to me that you may have disturbed the wiring when lifting the tank and removing the stock gubbins to fit the Ramair.? try lifting the tank , pulling the plug from the fuel sender , clean it up with some brake cleaner , then give it a nice smidgen of dylectric grease and plug it back in . Another thing I have noticed that can happen is when the tank is lifted and propped , the float can get stuck causing the problem you describe . . good luck !
 
Thanks, I will try this.

Don't get discouraged, after getting the Carpenter kit installed mine quit going all the way to full, 4 1/2 years later, it spontaneously started working fine again, no clue, lol.
