2005 GSXR C28 Fix

[@swichv64]

Just did this to my 04 gsxr and it worked!!!! Tips: -Use wire cutters to cut the heads off of the rivets -The position of the loose sprocket DOES matter. I put it in willy-nilly the first time and not only was the engine code still there, it made a nasty grinding sound!!!! -Even if your factory solders look okay, you should still try this. Mine looked perfectly find, just a little browning before I did the fix.

[@GregMalaka]

Thanks for the reply, glad it helped. Hopefully everyone will READ THESE HELPFUL TIPS listed by swichv64 !

[@Wafflebrah21]

Would this cause a no start situation? The c28 code

[@DonCharlos89]

Thanks for the video. I was having some strange issues with idling, throttle response, and power and it turned out the be the STVA after diagnosis. Removed it with the instruction of this video, and added some solder to the clearly detatched existing leads. Fired the bike up and it's back to its old self. Thanks for the tutorial. Ride safe!

[@Neilster750]

Dude Your little trick with turning the key and it will line its self saved me you have no idea I couldn’t get it to line up manually thanks Homie

[@danny_inwood_photography]

Mine went all 'FI' on me last night whilst on a ride. Shorted the pins to find c28. Followed this video and it worked a treat. Many thanks!

[@MayanWarrior86]

Awesome! Thank you. Just did it in 20 minutes and you saved me $1200.

[@daanwentink9111]

Thanks a lot buddy. Had 2 faults in the system, the c28 and c29. After the modifications they were both gone!

[@boercker09]

A few updates that everyone needs to know on this! I just fixed mine, and you will in fact need to take out the 4 screws on the actual STVA motor. My connections on the outside of my unit were fine, but the 4 connections on the INSIDE needed re-soldering. Also when you are first taking the unit apart, make sure you mark where the gear is. Mine needed to be in the all the way forward position. I am not sure if this will be true for all, but I would assume so. Do this correctly the first time and save the headache of having to do it twice. My bike runs fantastic now. Harbour Freight has a soldering iron for $4 btw ;D Reply to this with any other questions and I'll help as best as I can

[@markgalligar1300]

Nick Boercker hey , how do you take the stepper motor out

[@donaldgeorge1]

i did this trick but did not check with ohm meter big mistake cause it failed (make shure you check your work before you reinstall on your bike us a ohm meter to check for resistance) will take it back apart in the morning and redo everything I just did yet again tyvm for the vid I really hope it works for me :) 39k miles on the bike hope my sensors aren't burnt beyond repair

[@pansas1115]

Wonderful video! Worked for me and it was too easy. Thanks man!

[@GregMalaka]

no problem man. Glad I could help.

[@borbor122]

Awesome, you sounds like an MMI grand and an A Tech :) This is helpful for many people totally lost.

[@lifeon3753]

Thanks heaps for posting that mate. Much appreciated.

[@Motoherb]

I have a 07 600 and my Stva flickers. I’m hoping I try this and it fix that problem. I don’t have no codes. Just when I turn my bike to prime it my butterflies just flicker

[@lostcause2x]

Just fixed my mine.thanks a lot! Very easy fix

[@mackenzieharmon826]

What's going on brother I took mine off to dismantled it like u did and there were two really thin washers on the end of the motor when I pulled it out of the casing u didn't have any of those on yours?

[@Foxstang4life]

Good vid...im about to dig in to mine on a k5 1000 .. ive been everywhere chasing down a spudder and power loss ..dide everything except check the resistance on the actuator ..its not operating like it use to ..

[@Alexmoto86]

Qué sucede si se elimina el servomotor y las mariposas secundarias? Saludos fesde Chile! 🇨🇱

[@GregMalaka]

@Danny Inwood- no problem man, anything to help out a fellow rider! Again, apologies about the video quality and my filming capabilities. @MRSBA7- I searched high and low to find the specific part, when I called suzuki they told me i'd have to buy the whole throttle body. Its made by Mikiuni, you can try to pull yours out and look at the part number and try to match it, some model kawi's and mitsubishi cars used the same part.

[@naiemhosein2096]

Informative vid. Any idea of what of what other vehicles uses this part? Thank You..

[@mauricioroman6693]

My gsxr has the c28 code and it gives me a hard time turning on sometimes. Did that happen to everyone's bike as well or just mine ?

[@Aalonahams]

Mauricio Roman you ever get a answer?

[@ghathaway74]

Did you say something at the end about SportbikeLites? Do you happen to be located in Cocoa, FL??

[@geofferyotto5754]

Awesome. This vid helped alot.

[@Zx14rrrrrrrrrrr]

I'm not getting no code but my fast idle doesn't work.. When I turn the key it spins like it's going to work then it turns back. I'm guessing it's the stva thing.. If someone knows please help.. Things would be easier if I was getting a code.. That way I would be sure.

[@TheGsxr1975]

Good looking saved me money

[@70NastyLac]

Do you add the solder individually? My board has no solder at all

[@apexaddicted1]

Informative vid, horrible camera! Just did mine and it works great. Thanks for the info.

[@davidlivesey4809]

witch terminals are supposed to be soldered together?????

[@eastoaklandsartiebo-bo6718]

Will it cause a no start ?

[@GregMalaka]

@apexaddicted1 yeah...sorry bout that. I'm still pretty new to the whole vlog thing. iPhone in one hand and working with the other doesn't work so well I guess lol. Thanks anyway for the reply!

[@GregMalaka]

yeah apparently this was a bad year for the gsxr....sounds like the same problem as mine, mine was idling rough when stopped and i had a serious loss of power. if you do the jumper trick and look up the code you can figure out what the issue is....not a hard job at all. Soldering iron works better than a soldering gun, good luck!

[@alkhatibziad723]

Sorry if this is a stupid question but a lot of pictures and videos aren't super clear in the sense of soldering. Am I soldering 4 points individually, or am I connecting the 2 closest points to each other? Thanks

[@greggarton7451]

You're not connecting either of the prongs to each other. Just simply heat the old solder up (which can provide a temporary fix) or heat it up, remove it, and replace with new solder, the reason it may look like they're connected is because I used a liquid electrical tape and it just stuck to it. Without the solder on there the plug with the 4 prongs will simply fall out of the board. There's no stupid questions here, thanks for watching I hope it helps.

[@alkhatibziad723]

+Greg Malaka thanks for the quick reply. Alright thanks, I'll just solder each on their own. Maybe you're right, no stupid question just a stupid design on their part :/

[@scewston420]

having this prblem on my 04 now, went out this morning tostart it and it just cranked and cranked but wouldnt start up, the STVA is making a growling noise so i assume its stuck... the guages arent the right guage for the year so i dont know if it will show a correct code, i jumped it into dealer mode and it shows C00 lolthe bike started for me i went to the gas station and filled it up and it wouldnt start again had to truck it back home now the battery is dead..

[@greggarton7451]

I hope you didn't leave the jumper in the plug lol! I think C00 is what the error code is…its been a while since I've done this but good luck man! if you have any questions feel free to ask on here or PM me. Mine went out while I was cruising down the highway and I couldn't get it above 60mph (and) 5,000rpm while accelerating, it had a growling sound as well.

[@jpruitt546]

Greg Malaka c00 means no problems are detected.

[@swishahouse420]

turns out the kill switch was shorting out, rewired it and never had a problem again

[@vetteluvnh]

Great info! Thanks man

[@quintinappleby4433]

will this work for an 06 gsxr 600?

[@anthonydellacroce3447]

That's what I wanna know. Mine stays open all the time and twitches back and forth about 1/4 closed to WO, but never closes. Not sure of the issue, of if someone modified it.

[@collyflower66]

When I put mine back on I couldn't get to Aline even when I turned the bike on

[@HeyMrRager]

Will this work for a 2007 gsxr 750.... its showing a c28..... will doing this correct the functionality of the secondary throttle valves that tend to stay open?

[@GregMalaka]

Possibly….I'm not sure of the specific codes for the 2007 models….chances are they're the same as the 05's but I'd look up the c28 for your model just to be on the safe side. I can't believe how horrible the camera is on this….tried using youtube's "shake fix" feature…..sorry guys.

[@nickherrera1952]

HeyMrRager i have the same bike with the same code coming up. did you try this and did it work? The manual says that this is the same code that he has.

[@HeyMrRager]

naw but heres a link to a forum that has a small check list to go through to isolate the problem.. i guess the diagnosis is different for k6 and k7 gsxr's.. so i wouldn't recommend jumping into stva repairs without checking everything out. www.gsxr.com/showthread.php?t=91597

[@nickherrera1952]

I was reading everything i could do avoid having to drop all that money. All i had to do was use some electrical contact cleaner an the code went away!

[@HeyMrRager]

haha really??? can you explain what you did exactly?

[@MRSBA7]

whats the name of that part? does suzuki sells it? apart.

[@supafrancis]

*So this is for the 2004-2005 600's and 750's? -I Ask because the 04' GSXR 1000( K4 ) is a different bike from a 05' GSXR 100(K5) *What year is the bike in the video? Are you sure the 04' and 05' 600's are the same? - above question's reason being why I ask *My bike is a 05' GSXR 1000-Wondering if repair and part are the same. If bike in vid is a 04' It may not be if 600's are like the 1000's and differ from 04' and 05'

[@alexrod71497]

Was your bike bogging out?

[@kenzonderachternaam2946]

I had the C28 and had my bike fixed. Now the secondary throttle valve is always open and the bike runs fine. But is there anybody who knows how to get the red light off? Bypass it somehow or cut a wire?

[@jonnybds3]

If the light is on and its stuck open, it's not fixed

[@kenzonderachternaam2946]

Yes I know it is not fixed properly. The official Suzuki dealership told me that in my case this was impossible. They had experience with racingbikes and for those bikes the secondary throttlevalve is open all time on purpose. On the track you only ride in high revs, which makes it benificial not to have a secondary throttlevalve. I sold the bike btw

[@jonnybds3]

Ken Zonderachternaam I have over 2000 successful repairs that says the dealership was, and is, wrong. And corner exit on the track is where they're most important.

[@okankarabulut003]

You sure that's not a k4?

[@xxcowboys00xx]

How do you remove the solder

[@greggarton7451]

Just heat it up with a soldering iron or gun and use a paperclip or a solder stripper (handheld tool made to take off solder) and just pull it off and wipe it on a paper towel or wet sponge.

[@jonnybds3]

Your opinion of the error is incorrect. Anyone who tries to repair their STVA in this manner will experience this issue again. For a permanent repair, go to www.STVA-Repair.com.

[@GregMalaka]

I've put 14,000 miles on mine since i've done this fix…..still no code. To caveat though I did post the link for "The Geek" and did tell people he is more reputable than myself in the description.

[@leon-fz4cd]

GregMalaka you the best! thanks
