Sort your TPS 👍 98 Mk1 Suzuki Bandit 1200n TPS check and adjustment

[@williamfoster4268]

TPS does nothing except retard timing, best left unplugged.

Hi @williamfoster4268 , I feel I need to make a follow-up video on this topic , tps tells ecu what you're doing with the throttle, ecu uses this info along with rpm and gear selected to calculate correct ignition timing . Ignition timing consists of three layers , in old distributors it was base timing + vacuum + centrifugal gives total timing. Tps is just more modern electronic way of calculating how much timing to advance or retard from static base timing. Seems to me to disconnect it may be leaving a lot of performance and efficiency on the table, also the incorrect ignition timing could potentially be damaging if not catastrophic

[@williamfoster4268]

@@emeraldbandit1200 These bikes have no ECU(Or CDI, it's actually a TDI). The TPI is only used to retard timing during a cruise condition in order to get better MPG. Take your Bandit and run back to back dyno pulls, you will not see any noticeable difference in power made or lost. TPI was only added due to Euro 2 or 3 emissions controls. Timing on these bikes is conservative from the factory, hence being able to slap on a +5 degree ignition advance or drilling out your own and still being able to run 87 octane without pinging or detonation. I hope this clears up some confusion you have have had.

[@emeraldbandit1200]

Semantics aside the flip side of retarding the ignition for cruise condition is advancing it on acceleration, better mpg is definitely a good thing, bandit 1200s are thirsty. Advancing the ignition doesn't give more power but it certainly gives better throttle response and riding feel and yes this is what a 5 degree advance plate gives you but the fact the tps tpi or whatever you'd like to call it is adjustable means its quite easy to add 5 degrees or whatever you would like by adjusting the sensor .

[@williamfoster4268]

@@emeraldbandit1200 No, you can't add timing over base with the TPS. It can retard from base timing or go back to base, but not advance past that. Advancing ignition can and will give more power provided certain conditions are met. The only way you are advancing ignition is by drilling your pulse wheel or bolting on an aftermarket solution. You gain power down low using an advance, it's not much on a Bandit though.

[@emeraldbandit1200]

But you can move the point the timing changes and in my experimental adjustments on my own bike certainly translate to changing how the throttle response feels particularly at less than 3500 rpm and play a large part in sharpening up the 4k kick in power, not gaining total timing advance but starting the advance curve earlier adds relative advance at least until it maxes out. Ultimately it would be well worth making a windowed ignition cover and a timing light to see for real whats going on there and if I can gather the necessary I'll certainly make the video

[@ianthepelican2709]

Excellent explanation of a very misunderstood item. Many thanks. Cheers

[@johnb5352]

Brilliant,simple to follow instructions.Just checked my 96 1200.I got readings of 5.7 & 4.1 which was only 72%.Adjusted it to the 76% which is 4.3,& it seemed to immediately tick over better & smoother.Don’t think it’s my imagination.Will take it for a test run tomorrow & see.

[@peterdonnelly6804]

This makes me dream of having a TPS issue so I can fix it. Thanks.

[@alaintre4323]

thank you. from france. my honda varadero 1000, s'étouffait à 140 km/h. je vais faire ce réglage demain. thank you for ,this tuto bye!!

[@id.747]

Super helpful! I have an 01 B12 and had no idea my TPS could be adjusted. Now I’ve got to go check mine lol

[@emeraldbandit1200]

Glad to help 🙏 makes a HUGE difference to the way it runs - well worth the effort 👌

[@smerd1]

Just bought a 2000 1200 bandit in need of some TLC, this was a great video well explained, thanks for posting 👍

[@emeraldbandit1200]

Thanks 👍 you'll love the B12 ! Awesome bike - congrats on that 🤛 I've got a few more videos in the pipeline on the other work I've done on it to resurrect it , coils and ignition , carbs and fuel system etc hope you might find some of them helpful too .

[@markwhitehead7321]

Thanks for taking the trouble to make this video.

[@Trevor41167]

Excellent vid composition and advice, really helpful. I am experiencing exactly the same issue. Found my TPS to be out of spec, so ordered a new one. Will set up as you described - munch thanks to you👍

[@adamlanglois563]

Thanks for taking the time putting this together

[@rbmcstore2497]

Very useful, we have a bike in which has great compression, valve clearances within tolerance, timing is right, its sparking, new plugs, air filter, oil etc... Seems to be fuelling ok, we also sprayed carb cleaner down the intake and still no fire, not even an attempt, checked the tps and its out of limits, shows absolutely NO continuity. New TPS on the way :)

[@isaqueflorencio]

The best video ever i've seen about this service! Very glad to you! it was very useful to me. ;-)

[@brianfinucane8155]

Great video. Thanks for putting this up. I have a 2000 bandit 1200 and the video helped me alot as I had to replace my TPS lately and the info you gave was spot on. Cheers

[@jonathonrogers9461]

Thanks for taking the time to make and post this video 👍

[@alphabob01]

Really enjoying your channel,I have 98 bandit and never even thought of checking the tps, have had slightly annoying carb issues since I got the bike, just checked the tps and it’s reading 9.3k pins 1&3 and 8.4k pins 2&3 throttle open…..new tps required by the looks of it! Aaaargh!! Keep up the good work, Rob.

[@petrovski1948]

Excellent tutorial…. Thank you.

[@liamjackson2542]

Just the video I needed right now thanks emerald bandit

[@stuartbailey9941]

Very useful video, many thanks. Ride safe.

[@zezinhosoberanomcgoncalves2487]

Obrigado, me ajudou muito parabéns

[@notoriousb600_official]

Thank you for demo i was wondering how to do it

[@rumbleweedbeats777]

👍 Thanks for the upload, very helpful

[@emeraldbandit1200]

👍

[@gregoryz3]

always thought mines to advanced at idle, never thought of it being this.

[@rumbleweedandtheriddlecatc355]

Maybe you could now get around to fixing the heater in our car, from your lovely wife.

[@emeraldbandit1200]

😟 yes dear 👍

[@kevinhancock4064]

This is so like my partner and I..ha ha love it

[@MatthewBoothPhotographer]

Great video bandit!

[@emeraldbandit1200]

Thanks 👍

[@bizman185]

Good clear video:)

[@kevinhancock4064]

So the 1ohm at closed was normal right ? Mines a 1400 but similar method I believe I need to adjust mine tyb

[@pshivjee]

Hi, Is this a fuel-injection Bandit ? Is It the same procedure for an Bandit GSF 650, as mine was misaligned during the throttle cable changes. Gave me a Bloody headache 😢😢😢

[@rumbleweedandtheriddlecatc355]

Sweet!

[@FirstnameLastName-sx8ls]

Awesome. I have an 02 B12. About to do this.

[@kevinhancock4064]

That was the stps righy ? Not tps ? Ty

[@grabir01]

Is it the same for the 2002?

[@grabir01]

Also. Why is there a TPS on a carb motor?

[@ianthepelican2709]

Because it's about when the bang occurs not how big it is....👍

[@pshivjee]

​@@ianthepelican2709ha ha 😂 🎉🎉

[@bigmuller1]

Forget tps...just add a 4 degree advancer

[@paulomarques9691]

76% or 78%
