I just bought a 954 (Japanese Specs),it only makes 180kph then it just STOP acceleration though it is still 7 rpm's. How can i remove this speed limit restriction??? What do i need to change in the bike?????

 

shift gears?

 

You think i didn't try this.. (7rpm on sixth gear).

 

Swap the brain with the American version. Thiswould be my starting point...

Do you know anyone close by with a 954? Maybe you two can swap parts and find the solution...

I honestly don't know how the governor is setup and would have to research it just like you.

 

it seems like speed limitation when reaching 180 kph.. I need to by pass this limiter..

 

Thanks my friend, i was planning to try this tomorrow. What worries me is blowing the other ecu or something in the bike

 

180kph is something like 110mph, wow sucks to be in Japan! Get on eBay and get you an US version ECMlike stated above!

 

or the speedo healer works. just make the bike see 20 km/h all the time.

 

check your splice points off of the speed sensor-the injection system will not
work properly-esp on a ca bike,which uses a oxygen sensor

 

How to change it depends on how they take the measurement in the system. For whatever reason, Hayabusa was rumored to only have the speed governor kick in when the bike was in 6th gear, so the kit tricked the bike into thinking you're in 5th. Try driving in 5th and see if it redlines or governs out.

Otherwise, disconnecting the speed sensor should work if the governor reads the speedometer CAN or J1850 messages. If it reads it off of gear indication and the RPM sensor, then disconnect that sensor and see what happens. There's a lot of different ways of doing it and I'm not sure what Honda did... You could always try swapping the ECMs, but ya never really know what else is different between the US and Japan versions.

Hope this helps!
