Cal Thorsen Let the bike warm up to about operating temperature and adjust the tps to 1.086. Worked for me, no problems since. Good luck

ninjayorkie ZX-12R Throttle Position Sensor, Inlet Air Pressure Sensor, and B3 onwards Subthrottle Sensor, wiring colors, just so you can work out which goes where. I got this information out of the workshop service manuals.

Wire colors to look out for.
Yellow+White = TPS output
Yellow+Blue = IAPS output
zx-12r B3+, Brown only, Subthrottle position Sensor.

TPS = Throttle Position Sensor
Y/W, Yellow White, output.
BL/W, Blue-White, power in.
BR/BK, Brown-Black, ground.

IAPS = Inlet Air Pressure Sensor
Y/B, Yellow-Blue, output.
BL/W, Blue-White power in.
BR/BK, Brown-Black, ground.

B3+ Subthrottle Sensor.
BR, Brown, output.
BL/W, Blue-White, power in.
BR/BK, Brown-Black, ground.

Kawamadgaz Hi alfadave11, if i squeeze the throttle it eventually coughs and takes off like a rocket. Iv put a new tps on (zx6 j1)and the bike is ticking over nicely. Had to do a bit of gentle adjustments to get it to tick over and rev ckeanly. Need to take it for a test ride.

Started bike up (had warmed it up before adjusting sensor) held bike at 3500revs(where stuttering started) and it still stuttered and backfired. Am I best to get a new tps? Or could it be something else. The engine wasnt under load just held revs at 3500 in the driveway? Any ideas??
when your cruising at 3500 as stated in previous posts what happens when you squeeze throttle open ,does it clean up or does it carry on doing the spluttering etc?

No, not at all. I was just asking as I was unaware Kawi no longer supplied them or what Kawi was even charging for them for when they did. You done a great job with this.

Kawasaki doesn't make them any more or at least list them as no longer available here in the UK. Saying that there may still be some available somewhere.

You could try https://www.partzilla.com/product/kawasaki register to see if they have any. There may be other places too,

Kawasaki Special Tool: Throttle Sensor Harness Adaptor.
ZX-12R A to B2, 57001-1521 NO LONGER AVAILABLE UK Price: £16.22
ZX-12R B3 to 6, 57001-1538 NO LONGER AVAILABLE UK Price: £12.78

After tracking down what plugs you need (which I'll probably list later) and if you can order a single one, which may cost up to £7 you then need to order lengths of wire colors £9 or use whatever you have available if you don't mind the colors being different. Then you will need a crimping tool to attach the pins, £15. I suppose you could solder them and file any excess out so the pins fit in the plugs, knowing that if you've only bought one plug and you knacker it while fitting a pin you need to get another one. Plus you will need the bullet sockets for attaching probe leads, these will come to £6 in packs of 20 and you only need one half. Then the time to make one about an hour each. If all goes well you could make one for less than £10.

I had the crimping tool after making some for the zx-9r. When I found the plugs for the zx-12r minimum order was 5 plug set, so that's why I made 5 sets, I then found out the zx-12r B3 onwards uses smaller plugs so had to find and order 5 sets of those. This is the only reason I made so many sets, I only planned on making one for my B4.

For and against.
For, it makes doing the job piss easy.
Against, you only need it for 5 minutes checking or adjusting.

If you're going to make your own TPS test leads to a good standard, you'll need:-
Search ebay for, "3.9mm Brass Bullet Female/Male Connector DJ211-4A DJ221-4A Insulation Sleeves" for the patch in test leads to fit.
Search ebay for, "3m 1mm² 16.5A 12v cable wire wiring loom" then select or look for, Yellow/white, Blue/white, Brown/black. Same colors need for all zx-12r's.
Search ebay for, "Professional Ratchet Terminal Wire Crimping Pliers Tool Kit 4 Dies" or whichever takes your fancy. As well as crimping I also soldered.

ZX-12R A - B2.

Now you have all the information I have sourced, you can decide for your self if you want to make your own.

Just a thought, do you think I'm charging too much for the extra ones I made?

Found this on ebay which should work on the B3 onwards, search for "KTM Husqvarna Throttle Position Sensor TPS Diagnostic Harness Test Tool"

ninjayorkie Added B3+ testing pictures to the bottom of page 2.
10-17-2018 03:13 AM
ninjayorkie I just tested the B3+ one out on my B4 bike, 5 minutes, worked a great resistances checks and voltage checks ok.
TPS plug was a little tight to get back off but all in all a nice bit of kit to have, even if your hardly ever going to use it.
Im waiting for bullet connectors to build the rest, but I’ll let you know when there made steve.
