Tip over sensor

[fixxervi6]

Do you guys disable your tip over sensor? I've read some bad voodoo about the gixxer TOS's and that its pretty easy to disable them (fill em with silicon and the such).

Is that a common practice?

Untill last month I didn't even know my bike had one. Never had any issue with it. Unless you're really into the stunting side of things I wouldn't think it would be an issue.

[sckego]

Yeah, I've never messed with it on any of my bikes. Then again, I've never had a GSX-R, either...

[mattjmartin]

Your kickstand spring is going to give you issues with cutting out long before the tip over sensor does. Unless of course you crash a lot, but I'd be worried about other things if that were the case.

What exactly have you read that talks so negatively about the tip over sensor?

Tip over sensors include one roll, and some bikes have them for pitch (although not many, otherwise a wheelie or stoppie would kill the engine). If you lean too far over, it assumes you've crashed and kills the power to the engine. I don't know what the specifications are tuned for, but it's something really significant... like 80-85 degrees maybe? However when you are doing stunts that are hard on a bike (coming down hard from wheelies and from stoppies, etc.), the constant smacking around can jar the mercury inside the tip sensor and cause it to shake into one side just right to have it make a connection and kill the bike. I wouldn't consider this a problem with the tip sensor as much as I would consider it a problem with the way the bike is being ridden or treated. Filling it with silicone means that if you crash or wreck, your engine will not shut off. If you are knocked out and your bike just has a scratch, it's going to run sitting sideways until it bursts into flames.

For every day, standard riding, track riding, even racing, unless you're Valentino Rossi and you're over at lean angles approaching the tip sensor's trigger points, you don't need to mess with it. I've dragged peg and plastics before I tripped the tip over sensor.

As with anything... don't fix it if it's not broke. I have a Gixxer as a race bike and have had it leaned over to the point of dragging peg, toe, and plastics. And it didn't trip the stock tip sensor.

never had a problem on my gsxr, but then I'm not leaned over far, and dont stunt.

[fixxervi6]

Its not about the angle that causes the issue, its about the ass end slipping a little then getting grip again, physics comes into play and the sensor can get tripped.

gixxer's don't use mercury, see link below for better description of what I am talking about

Its about older models but googling around it appears to be a pretty popular topic still.

If it was just an old issue or something cool, I don't stunt or anything like that.

Doh, for whatever reason that's blocked at work.

Your an IT guy and your name is firewall right? bypass the block

Hrm, that doesn't seem like a very fool-proof switch, at all. It's just a ring mounted on a U-shaped slider... during normal cornering, the ring will stay centered, but if it recieves a jolt, it will slide up to one side and contact either of the poles, which kills the engine. I can see how a big moment (such a near-highside, even if recovered) could jolt it enough to kill the engine.

thats why it got my attention, I don't know if the 09 is the same, I was thinking about pulling it out and looking at it but I really don't want to go digging in any guts if its no longer made that way/possible issue

[mattjmartin]

Like firewall said, leaving it is probably a better idea than fooling with it. The last thing you want to hear after an off is your bike on it's side in a ditch pegged at the rev limiter. I have experience here from my Frankenstein SV that didn't have a single sensor on it. If it has problems, rather than disabling it, I'd go as far as to replace it with a better deigned unit from a different bike. The safer, the better.

[DarcShadow]

My Daytona 650 didn't have one or at least it didn't work, and while I was laying there on the side walk I was thinking, "Crap, my bike is still running, I have to get up and turn it off."

[Firewa11]

Yeah but it's because it's a Triumph.

You need that tip over switch IMO. Fuel injected bikes will not die like carbed bikes when they fall. Then no oil pressure, and you've got WAAY bigger problems than a faulty tip over sensor

Yeah, broken bike is the last thing you want after breaking bones.
