Damn, just got the bad news from the dealer mechanic. His price is $1900 out the door. I didn't pull the code myself. I doubt a dealership would rip me on that sort of thing.
The bike runs great (just won't go over 80). What damage could be done to the engine if I continue to drive it ( I use it to commute into work)?
I'm bummed bigtime. I'm in the process of buying a house and this couldn't have come at a worse time. Does that price sound about right?

:mad

Take it somewhere other than a stealership and get an estimate. $1900 seems a bit like highway robbery to me.

 

[redthundr]

check the code yourself... from the problem you describe, i'm willing to bet its C28: Secondary Throttle Valve. If it is, just remove the secondary butterfly or find a way to keep it open. Mine did the same thing.

$1900!!!! If it is truely the Secondary Throttle Valve Actuater, you may have to replace the entire Throttle body assembly. The reason I say that is because according to what I see in the Microfiche on Ron Ayers W/S is that the STVA is not available by itself. Now I didn't spend much time there so maybe it's somewhere else other than the throttle body page.

Even if you had to replace the whole assembly, the list price is $622 for an '05 Gixxer 600. I don't know if you have a 600 or a 750 but should be about the same. $1300 labor????? Wow. Now keep in mind, we are assuming that you're throwing a code 28. You should really find out what the code is, get the service manual for your bike, and diagnose it yourself if you're inclined to do so.

If it turns out to be the STVA, see if you can get a part number and replace it yourself. You'll need to recalibrate the sensors but may be worth the savings.

Then again....what do I know:scratch

 

[redthundr]

Yes, if it's the STVA you have to replace the whole damn throttle body and it aint cheap. Even if you find one on ebay most of the time.

They're not needed, they are there purely for emissions reasons. Team Yoshimura removes them and recalibrates the CPU, but you don't have to go that far.

Just remove the sucker and be done with it. The only difference you'll really notice is a bit lower rpm at idle and you can adjust that easily.

Thanks for the honest replies guys. I about fell over when he gave me the bad news.

I'm decently mechanically inclined but I don't have much free time to tear into the STVA's. The mechanic did say that he would need to order the throttle assembly and gave me a price of $800.

I assume it won't mess things up to ride it while I'm contemplating my game plan with this thing? I'm going to pick it up tonight and do the paper clip thing.

 

[gsxr600k5red]

What I don't understand is that in the service manual it says that if you find the problem to be the STVA, replace it. How the hell do you replace it if you can't get it?

 

[racer2c]

And if I remove the ST's how do you clear the C28 code and get it out of "limp" mode?

Is removing the ST's something a non-dealer mechanic might do or do they not touch it because it's emissions?

That's a good question. I don't know. The code is thrown when the actuater fails. Removing the butterflies is not going to fix the problem as far as the computer is concerned. I would expect the bike to ride fine though.

To anyone having or has had this problem on an '04 or '05 600. PM me if you still have the bad unit. I will pay for shipping. I bet I can find a way to fix it. My guess either the motor goes, or gears, or position sensor. Mine works fine, so I don't want to take it apart. I just want to find a fix for this. So many people having problems, and this thing can not be that complex. If I can fix it, I will return it to you so you can sell it. If I can't, well, then you're out nothing.

 

[shittygsxr]

the bike will ride fine but you will still get the error code. I think someone on this board was working on a fix for the code

It does ride fine, just won't go over 80. Maybe that's not so bad...kinda like a governer. hmy

Damn, that sounds like fun. I do that with things all the time that are suppose to be "unserviceable". I have a bunch of washing machine timers laying around that I tore apart and fixed. Let me know how you make out.

I just had this same problem with my K4 750....go on ebaymotors and search for a K4 or K5 throttle body. I got mine off of a wrecked K5 750 for $95 shipped! Prices will very, but mine was like new! A new throttle body system will cost about 700 from Ron Ayers. It's incredibly easy to replace and will run like a champ with a new/used one. Ebay is your friend....most of the time.

 

[down_on_monday]

Oh, and $1900!!!! Fuck that, you are getting raped dude.

 

[racer2c]

This guy has one off a 750 but doesn't give the year. :wtf

This guy has one for $200. Can someone tell me if it includes all that I will need from looking at the pics?

Thanks!

The best way to find out is to ask the guy who's selling it. Make sure he guarantees it has the part you need.

Oh, and make an offer!

Good luck. :cheers

Looks good to me. The STVA is still connected to the side.

My K5 600 did this while on a 500+ mile trip to Cali and back. My dealer in Vegas said that the warranty I purchased with the bike doesn't cover this repair, but after about an hour on the phone he got a rep at Suzuki cover it under emissions. I can get the paperwork and the rep's name when I get home if you think that would help.
I paid $0 for all the work, had to replace the throttle bodies. I think it was like $1100 and change after it was all said and done. Suzuki covered it all, not my dealer or my warranty..
