TPS adjustment instructions here(Big improvement!!)

[allan4169]

I did the TPS adjustment on my 2001 1200S Bandit and the biggest plus that I have noticed is that it idles much better in the cold with only about a 1/4" of choke knob movement. ( I know, not a choke but a fuel enricher) I will check for a while to see how the fuel economy is.

OK couple of idiot questions on the TPS adjustment.  I'm assuming we adjust with the ignition on, but the bike NOT running yes?  Obviously need to disconnect it to get to the pins...we're talking about the resistance on what's attached to the carb right, not from the plug?  Next idiot question: the multimeter, I should put the ground (black) on the frame and the red (+) on the pin yes?  or Black on the top pin and red on #2 and #3?  Sounds like one of those things that takes about two minutes when you've got it figured out.

Whoa there, big fella..... I think you're on the wrong track.  Based on THIS POST, which has a pic from the factory manual you....

... Don't turn the ignition on
... Don't touch the multi-meter probe to the frame
... Don't use the plug - use the carb end

Since you're measuring resistance there's NO polarity to worry about.... black and red mean nothing except you'll need to pick one color for the end pin and keep it there for simplicity.  The other color is swapped between the other two pins and measurement is taken at throttle closed and fully open.

Well that clarifies things thanks!  I'll look at it tonight.

#1 closed 6.4
#2 open 4.8

= exactly 76%

No adjustment needed..  Nice to know anyway!  Thanks for the info.

To date I've installed a Dyno Jet Stage-1 kit, synced the carbs, adjusted the valves, installed new spark plugs and air filter.
After all that she still had a stumble at mid-range that I suspected was ignition and not carbs.

So, I checked my TPS tonight based on instructions found here. 

Don't think TPS had ever been adjusted, so assume this to be the factory setting:
Ohm-1: 4.85
Ohm-2: 3.88
80% 

Set to:
Ohm-1: 4.85
Ohm-2: 3.69
76% 

Went for a quick test ride  , much better

Ya, that did the trick! 
I rode the Bandit to work today after adjusting the TPS. 
BIG difference.  Smoother across the entire rpm range, and no more mid-range hessitation. 

Now, do I buy a Holeshot 5-degree advancer?

so has anyone tried different %'s
what happens at 90% vs what happens at 60%

just numbers   mine seemed to range from 66 to 85 %

Hi
Once again my Jap model GS1200SS is different from all your models.
Can some one tell me which color wires come from each of the three terminals in the TPS.
Reason is that my TPS terminals are in a triangle shape not in a line like your so it is hard to know which terminal should be the common and which terminals are the ohm1  and ohm2.

I have yellow and blue and black/white wires....on your models which color wire goes to which TPS terminal.
Thanks

Hi Rich,
I got a jap B4VVC with tps and on the jap models the black/white is usually the return so would think the yel and blue will be the two, mine has blk/wh,green and red so im unable to say which way round yours are.
