I saw this thread:
http://forum.svrider.com/showthread.php?t=92770

I then followed the instructions from this thread:
http://forums.sv650.org/showthread.php?t=55459

I was able to find the dealer connector easy enough and got the bike into the diagnostic mode.

My first problem came when I tried to find the idle adjust screw. My bike doesn't seem to have one.




Well my idle is close enough to 1300 and I was at it so I continued on.

My next problem came when I went looking for the TPS its self to adjust.

Mine is very different looking than the one pictured in the thread.



Now I was able to check the current setting for the TPS by way of the bar when in dealer diagnostic mode.
It is currently set at 4600.

Lastly when looking at the owners manual that came with my bike the section on idle says to take it back to the dealer to adjust the idle.

So mainly my question is has anyone with with an 08 adjusted their TPS or has it just been assumed that it hasn't changed from previous years?

At this point I am really at a loss. It needs to be adjusted, but I know if I go to the dealership they will just say that is is right because the bar is in the center when the bike is at idle.

I have been searching for weeks and never saw that thread.

It sure seems to answer the question about the TPS adjustment.
I will take a look this weekend and try to adjust mine again.

I still don't see how to adjust the idle.
If anyone has any ideas on how to adjust the idle please chime in.

Both of these things changed in '07 as I discovered when I worked on mine. We have an electronically controlled idle so it shouldn't need to be adjusted. And the TPS now just has a single security screw. The OP took a good pic of it, it's the half circle looking part with the tab on top that has a white line painted on it. Adjust it as you would the older TPS sensor. All that changed is the look like that thread described.

I have an 03. I did the idle adjustment and it just didn't work, making my bike much less rideable. I put it back where it was ( much too high, everyone said ) and regained all the lost tractability. I believe others have experienced the opposite result. Just know that in my case I wasted a bunch of time doing a "fiX' on a problem that wasn't really a problem at all. And ... the "fix" didn't work.

Ride on.

I finally got around to trying this again.

Based on the link that DWS909 supplied I was able to adjust mine just fine.

It certainly made a big difference in the lower end of the throttle, but mine was way way off.

Hey, everyone - I've got a k7 that I did this adjustment on today, and it was almost too easy. I used the security torx in a thumb ratchet connected to a small ratchet handle (defeats the purpose of the thumb ratchet, I know...) and loosened the screw a bit until I was able to make very tiny adjustments to the TPS body without it wiggling around. After about 3 or 4 minutes of fiddling with the TPS, I got it really, really **** close to 1300. The bar goes from --C00 to the higher setting with the slightest throttle movement. I took the bike out for a test ride once I had her all buttoned up and it made a significant difference -- the bike is much more controllable at lower RPM. Seriously. Almost no jerkiness whatsoever -- and that was with me letting the RPM get to just over idle while I was rolling at really low speed in 1st gear. Accelerating out of those lower RPM was just as smooth. Engine braking is not as intense anymore and the bike feels so much more smooth now - in a very good way.

I read up on this and the manuals I saw online just showed bike in dealermode you turn it ever so slightly and it the line moves up or down, you want it right in the middle. I havent yet done this, hoping to when I get off work today.

I didnt see any mention of beign able to set to a value or read a value of where its set (4000 or 1400 etc)

thats basically the procedure right? Put in dealer mode, fire it up turn tps so the line just left of the c00 is in the middle and tighten her back down?

That's the way the manual discribe it. Only problem is that the range from the middle line is to big and that's the reason why some bikes are way off.

You can check the setting with running the bike and give it some throttle. At a certain rpm te middle line will go up and thats the rpm to set the TPS sensor on 1450 rpm.

When setup correct the line will go up when you throttle it and the rpm reached 1450 rpm.

Anyone replace the crappy Security Torx bolts with better quality allen head bolts?

If so - what size are they?

Thanks.

Well I was about to change mine out today but all I had was M6 and M3 and those are definitely not the right size. I'd wager M4x0.8 as the 1.0 thread pitch on the M6 didn't match the security torx bolts. Since M5 is 1.0 pitch too that's why I'd guess it's M4.

Just did my '06. Factory set it at 3600rpm. Makes a noticeable difference for sure, glad I did it. And, yes, the bolts were cheesy.

fwiw, they are NOT factory set at 3600rpm

its something that goes out of adjustment over time and miles, like many other things and that's the reason that TPS adjustment is routine maintenance


adjusting the TPS is something that should be done at 600 mile service and every 7500 miles
