Derestriction of the Jap model Bandit.
« on: May 19, 2009, 06:43:14 PM »
On Jap import B4's you will find an extra wire that goes from the gear selector to the cdi with a bullet connector under the seat. This wire is green with a yellow tracer and sends a different resitance for different gears to the cdi. It is used to restrict the B4 to 180kph as set by Jap law. In the first three gears the resistance is 1.5k ohm, neutral is zero and set by the black wire and 4th 5th and 6th 1k ohm. To derestrict the bike we need to tell the cdi that it's always in the low gears and so set at 1.5k ohm. To do this-
You will need one 1.5k ohm resistor, one male bullet connector, one female bullet connector, 6" of 1.5mm electrical wire and one ring end/bolt on type connector.
You crimp one end of the resistor into the male connector and fit this connector into the G/Y wire under the seat from the cdi, then slide the other end of the resistor up inside the female connector so as it acts as a cover/sleeve for the resistor and put the 6" wire coming out of the end of this connector and crimp them together, to the other end of the wire you crimp the ring connector and this is bolted to the frame under the seat. You leave the G/Y wire from the gear selector loose and connect the black up as usual. This will now tell the cdi that it is in the lower gears and the cdi will think that it never gets to 180kph and full power will always be available.

Parts needed.

Resistor crimped in male bullet connector.

Resistor crimped inside female connector with wire out of the otherside.

Finished wire with ring connector fitted.

You can use shrink tube to seal the connectors and give a professional finish.
Pleases note that no animals were in any way harmed or ill used during this operation!

So how would you do it on the American models? Similar or different?

Thanks Chris!

I'll be doing that today at some point  :thumb:

Hi Vid,
Did'nt know the US model was restricted. Its for the 180kph restricted Jap bike.

It may be similar, dunno. Does anyone know if you can de-restrict the US models the same way?

By the way, your camera should have a setting for shooting close-ups, typically it looks like a flower icon, like so:



Those close-up shots are totally out of focus!  :bandit:

I am just about 100% sure that US models are unrestricted.

180kph is 110 or so mph and that is easily achieved for me anyway.

I believe they are restricted. Fourth, fifth and sixth gears, IIRC. I remember actually being in a thread about it, but it never confirmed how to de-restrict them. It's uncertain whether you would screw anything up if you tried this technique on the US models.

Excuse the pics, my camera is pants. As far as i know only the Jap bike has the green/yellow wire. You should find that the non restricted bike only has a black wire from the gear that is the neutral sensor.

Hmmm, I have a green & yellow wire coming out of my unit. Check out my CDI below and look at the left-most cable. Perhaps there's a similar arrangement on the US models.

Easy. Just use the self-portrait mode.  :bandit:

Hi Vid,
Correct me if im wrong but im sure ive seen those pictures before :roll:
You want to follow that wire to the connector near the battry and i think you will find it connects up with the G/Y and a blue fabric coverd wire (neutral) from the gears.

Thanks Chris H

My B4, a jap import which is still restrict,  I alway know it was since the DYNO, never could find how it was restricted,  Bandit Ally BSS  is a great place. :bandit: 

Will do it within few days   :motorsmile:

Hi Unique,
PM me your address and i will send you one as you have to buy 10 resistors at a time.

Yes I posted this once before but I was never sure if disconnecting this on a US model would work or screw something up. So if the wire goes to where you're saying then all I have to do is ground this wire via a 1.5kΩ resister? As I said my hesitation was that I didn't know if this could be different for US model and possibly wind up blowing out the digital igniter.

BTW, would this also override the rev limiter?
