Speed Limiter Challenge
I challenge anybody technically talented enough to figure out how to bypass the CB1100 speed limiter w/o disabling the speedometer. There's probably somebody in Japan that's already figured it out, they've had 3 years to find the answer hidden in the computer. Now that we got pipes, pcv, airbox funnels, slip-ons, etc its time to find out what the top-end actually can do!

RE: Speed Limiter Challenge
There's a blue/pink wire that feeds the ecu from the Speedo, or on abs, it branches from the Speedo signal. If this wire is disconnected, the Speedo functions but you get the cel light and bike goes into safe mode...6k rpm max in any gear. I don't know what type of signal this is. If its a changing voltage, perhaps a resistor added would trick ecu that 112 is never reached even though it is. If its a pulse counter, I don't know. Maybe a speed healer could be applied to this wire instead of the Speedo wire and change the signal to the ecu to imitate a slower speed.

that's as far as I can get.

also, I don't think I want to be the guinea pig for the handling characteristics at 130 mph.

How about filling in every other hole in the speed sensor. I mean, you'll be limited to 224mph, but thats probably on going to bother one or two people out there...

Ack-CB11 found the answer to the challenge!
However, its a bit more involved (and expensive) than I was hoping for. Confused

Dont you just love translations? What the heck did that say? It looks to me like it keeps the 180 kmh national limit by reading bullet# 1 or am I reading it wrong? Carbon Shell magical racing ??

I think you're supposed to offer a $1,000,000 prize for a challenge like this. Or free beer.

Go hagofuku yourself.

That is a pulse corrector. So yeah you can hook it up to read half time i guess. Just like what the other guy said about filling in every other hole on the speed sensor. Down side is abs would lose all effectiveness

I figured the Aussie would have figured it out by now. I've ridden with a couple Aussies on a European tour. They are flat crazy for speed!
