Why do you want to? I've had my F4i w/ the exhaust scraping, and it didn't cut out. I'm not sure how the F4i bank angle sensor is, but I know you can fill it w/ caulk on the GSX-R 750 to keep the ball at the arc's lowest point.

I would think the centrifugle force in the turn would preclude the sensor thinking it was laying on it's side, unless you lean to the outside of the turn.

I want to bypass it BECAUSE of recommendations like those the GSX-R guys are getting. I've had a bike (not an F4i) cut out on me mid corner and it was pretty hairy. I'd like to do what I can to avoid that possibility.

The maintenance manual gives no description of the sensor. Without knowing what's inside the "black box" it's difficult for me to determine whether centrifugal force has any effect on the sensor.

In my experience dragging the stock exhaust on and F4i requires only moderate lean angle. I've done it on the street, and I'm not prone to aggressive riding on public roads. I've retired this bike from street use, but I'm still 2-3 weeks away from my first race weekend. I'm not sure what to expect. Just trying to be safe.

Sokitset, the bank sensor is mounted in the nose on top of the headlight assembly. Very easy to see with the nose off. I have no idea how to bypass this but I doubt it will be that hard. I know the bike will not run with the headlight assembly unpluged (lower din type plug at left front). I got mine low enough to cut out one time... still have a little pain in my right arm from that one

The RC has the sensor mounted under the seat. I have had mine over to the edge of the tires and never had it cut out but it did cut out in both crashes. You might want to place it in a different location closer to the center of gravity... if the wiring will allow it. The sensor is a good thing to have on the bike in the event of a crash.

Well, I work at a Honda dealer, so I'll look into it tomorrow at work. I'll see what it looks like in the computer, and if that's inconclusive, I'll ask the service manager. Reply to this so that when I check my email tomorrow after work, I'll remember to post.
