Default 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.
