Yep - been there!

Had first hand experience with this very subject late last year. I'd had a 2003 model SV1000 Suzuki languishing in the back of the shed for a couple of years after picking it up cheap - you know how it is!

Anyway I decided it was time to get it going and get it registered so I could have some fun with it. Of course, the fuel tank was full of rubbish as a result of my stupidity in leaving unleaded fuel go off in it. Cleaned out the tank and the fuel pump and got her going but there was a miss and splutter when holding a steady throttle at around 3000rpm, like when commuting.

Pulled out the injectors and had them professionally cleaned and put in a new set of spark plugs. No difference. Checked everything else I could but the problem persisted.

I then started thinking about the Throttle Position Sensor, and had a chat with my brother about TPS issues he'd had with his Moto Guzzi Lemans. He described the symptoms which sounded somewhat similar to what my SV was doing.

Anyway, I bit the bullet and ordered a new genuine TPS from my local Suzuki dealer. Only about 90 bucks which I was prepared to gamble.

Put the new sensor in and Lo and behold she was like a brand spankin' new one! It's an absolute joy to ride now - I love it!

Anyway, keep your TPS in mind if your bike starts running erratically on a steady throttle once it's a few years old.

After reading your post, I'm going to go ahead and replace mine. Running erratically, surging, oscillating.

Hi BB, if you do replace your TPS yourself, grab a scriber or sharpie and mark the exact position of your original one before you remove it. They have a range of adjustment available and are very sensitive to even the slightest of movements.

The Suzuki TPS is secured with a small Allen head bolt, I haven't looked to see what the Vic has. A neat feature of the SV1000 is a 'service plug' under the seat which allows you to use a jumper wire to set the optimum TPS position. It brings up a little bar graph on the instrument panel which is used to set the position.

I don't know if the Vic has a similar feature but if you mark the position of your old one and set the new sensor to that, you'll be well and truly in the ballpark. If you do a bit of googling first you should find the exact info you'll need.

**Edit: Maybe I should have done the smart thing and read the article attached to the link in the initial post - all the info is there!

Cheers,

Russ.

Since it's almost impossible to buy the sensor only and the whole throttle body is 350 bones, gonna have to cogitate on it.

How funny. I just posted a thread with the symptoms of "Idels great. Accelerates great. Noticeably missing if holding a steady speed like at 3000 rpm" sounds like I've found the problem. Thanks for making this thread. I'll head to NAPA to find which one I need. Unless someone knows for sure which one I need for a 2004 kingpin.
