Gsxr stva acting up

[@AndyGonet]

One thing i can say is,your tps has a loose contact,replace it ,it wil work fine again

[@Larctz]

Help

[@jarrettehill1258]

Fuel pressure regulator in the tank was the problem allows 43 PSI to the injectors if the spring no longer works it will just bleed out into the tank and you will lose RPMs etc

[@two4life455]

Yes that is your problem. Just remove butterflies all your airflow will be restored I had the same problem you’ll still have red light but it will run like hell

[@jamesfernandez878]

What do you mean by remove the butterfly’s because I’ve replaced mine once bike tan fine for like 7 months now sams issue stva is going again ot something

[@maxwilkinson7784]

Loosen the adjusting screw on the stvs, rotate anticlockwise till the sensor is rotated almost as far as it will go and retighten. Close circuit for the diagnostic FI indicator at the 4 pin plug at the back of the bike, you know what I mean and the lack of revs problem is fixed. There's now no temperature gauge, "28" indicates occasionally but I now have full power at maximum revs. This is a bodge. I don't know for sure but tuning may be altered somehow, leaned the mixture off maybe. I've done at least 1000 km since this fix and it seems OK.

[@maxwilkinson7784]

The bike I did this to is a 2004 gsxr 1000. It may not work on other gsxr bikes.

[@JB-zx2py]

Mine was doing the same thing. I had to rebuild the fule pump. New motor

[@jarrettehill1258]

And if it's nothing of these symptoms then it's probably electrical spark plugs or rectifier

[@MRzay786]

So if I’m understanding right is everyone saying to check or replace the fuel pressure regulator? Which is causing the Secondary throttle to spin like this when you put it back together? Because I have this exact problem.

[@jessygibbs4132]

i hear it’s a common thing that the solder contacts on the stva cracks and wires breaks loose on these gsxrs , put a solder gun back to them see if that helps, good luck!

[@jessygibbs4132]

sorry , i meant solder spots on the circuit board

[@jarrettehill1258]

@@jessygibbs4132 yes that is why I originally took it apart but was not the case now I run the bike without it and it runs amazing

[@jarrettehill1258]

I personally do not care for the stva add one lock up on my buddy at 90 miles an hour he is still with us but is a scary situation

[@jessygibbs4132]

maybe that’s what i need to do with mine, did you just unplug it or take the whole entire part stva off?

[@tylerlynn9684]

They make a stve, which is the eliminator plug in...just found one on eBay lol turns off the fi light they say. Haven't tried yet but Im thinking about it vs soldering my old one thats acting up again lol @@jessygibbs4132

[@maxwilkinson7784]

Cured my 2004 gsxr 1000. It's a bodge but it works. Loosen adjusting screw

[@jarrettehill1258]

Just unplug it you can run it without it if needed but if not do not mess with it if it's actuating properly it's probably fuel related like fuel injectors or pressure release valve in your fuel tank that actually it's at 43 PSI see the pressure coming from the tank with a pressure gauge if it is kicking 43 PSI it is most likely not your pressure relief valve could be dirty injectors rarely is though usually pressure relief valve goes out

[@jarrettehill1258]

That is exactly what I did it ended up being a fuel pressure regulator inside the tank on the fuel pump very easy fix they do not make it for certain years though the fuel pressure regulator but you can make your own fuel pressure regulator external on the tank that you can adjust the fuel pressure just make sure it is at 45 PSI that's what the black likes to run at

[@JB-zx2py]

@@jarrettehill1258 how do you make your own fule presser regulator? Do a video on that

[@jarrettehill1258]

So it wasn't even the stva a buddy at work told me to pull it apart which you are not supposed to they are factory set once you pull it apart they are garbage it was a fuel pressure regulator in the tank

[@brianr1373]

I’m having the exact same issue with my k6 600 what did you do to fix it replace?

[@kevinroach6914]

I have a 2013 gsxr 1000 it has power up till 7000rpm then falls flat

[@rickybarrett2854]

​@@kevinroach6914 did you solve your issue?

[@andygsxr7059]

Resoilder the 3 wires in the box

[@jarrettehill1258]

My buddy told me it was the stva acting up it was not I should not have touched it the solder wires were fine I actually ended up ruining it by pulling it apart the factory sets it on the teeth of the plastic gears and once you remove it it is fucked you have to send it to a specialist not too many specialists in the world that do them no joke I just ended up doing a delete

[@jarrettehill1258]

Just make sure if you do an external fuel pressure regulator that it runs at 43 PSI and it's a pain in the ass because you would have to drill through the tank and make sure the tank is solidly secured so no gas is leaking out of it but it was my idea to do an external fuel pressure regulator from Amazon that is adjustable just make sure it's at 43 PSI you can also do external fuel fuel filter that you can change out easier than the one in the tank pretty good idea would just take some doing on making the gas tank not leak maybe just welding nozzles for your new hookup

[@jarrettehill1258]

Mechanics call that fuel pump a sand trap because it literally there is a bottom filter little sock filter but there is an internal filter as well in there and once it plugs up your screwed you have to buy a whole new $400 plastic housing for your $30 pump

[@cordellbanks1670]

Did u figure it out i have the same problem

[@jarrettehill1258]

Yeah so I couldn't go past like 60 70 miles an hour it was a fuel pressure regulator a little tiny thing on the fuel pump in the tank it was blown out

[@jarrettehill1258]

It was a bad fuel pressure regulator do to the fuel pump being as old as the bike 18 years old

[@jarrettehill1258]

You have to buy a new fuel pump housing which will run you $500 approximately the fuel pump itself it is cheap like $50 or under with the seals highly suggest using seal Lube so you do not break the housing that was my mistake on the old pump

[@jarrettehill1258]

Also do not mess with that stva motor that controls the secondary butterflies if you pull it off it will make it useless you will run into all sorts of problems

[@tedd.g1636]

I got a new one and it’s doing the same thing

[@jarrettehill1258]

Yeah I've been through this a few times watched a lot of videos you have to get it on the throttle body you can buy it used once they are separated it will make that clicking and will not actuate properly

[@jarrettehill1258]

FYI I am currently running my bike without it I just have the failure indicator light on because of that little servomotor I deleted the stva people say you lose bottom end power I do not feel a difference not much at all just happy my bike can function the way it needs to again

[@tedd.g1636]

I just took it to the shop a couple days ago and turns out incorrectly installed the tps sensor just take it to a shop
