Okay Gav, its a little hard to tell from your pics as they are pretty out of focus, but my first thing that concerns me is that the end of the jet needle is broken off, it looks like.

My jet needles taper to a point just a bit thicker than a sailmakers needle - yours look like the point is about 2mm or more wide!

Also, can you take an in-focus shot of the throttle slide inside the slide holder mechanism. This is where the wear occurs and you will see it allows some slop in the throttle slide. Which means the jet needle moves around as it goes up and down, causing inevitable wear of the tubes.

Emulsion tube, or Needle Jet as per Suzuki parts fiche.
Damn, hard to get decent photos!

i havent heard people describe it as a wild bike so as long as you're restrained you should be fine i went 250 2 stroke to the GSXR and lived

[gav]

Broken? Don't think so, they taper down then maybe last 2mm taper off sharply to point. Kinda like the end of a pencil? Is this not normal for these? The black throttle slide when sitting in throttle slide holder sits quite flush, no sign of flaring that appeared in your photos?

[riffer]

Okay, it's gotta be your photos then mate.

I reckon (and take this with a pinch of salt, as I'm no expert) that as long as you don't have any ovalisation in the needle jets (emulsion tubes), the jet needles aren't worn and banging around in the jets, and there's no major wear in the throttle slides, you're looking now at the easy bits to fix.

I still think your needle jets will be worn at that amount of mileage, so if you've got the bucks go for that, and replace the float needles too. Have you taken them out and looked at them? They tend to get a bit worn and look like pyramids that have their tops worn away from them, and this might play havoc with the fuelling.

Also, it might pay to check the diaphragm rubbers as well. Make sure they seat right when you put them back in.

I need to balance my carbs, but I don't have the tools. Are there any KBers in Welly with the tools who feel like coming around and talking shit and balancing some carbs with me?

Gav, if your digical camera has a macro focus mode (and I'd highly doubt it wouldn't), use that to take close up shots of your bits (carbs! ). To find out if you're on macro focus or indeed if your camera has one, there will be a picture of a flower on one of your buttons, and hopefully it should show up on your screen as well once it's activated. This is used to focus on objects quite close to the lens of the camera. Make sure you've got good light though, if you don't the camera will use a longer exposure time and you'll get blur from handshake.

Sorry, I'm not much use on carbs unfortunately (hell, don't really know that much about photography either! Useless all around... ), but hopefully this will enable you to take a better photo for the experts to examine!

AFAIK, T.W.R knows a thing or two about carbs. Not too sure he's as familiar with Suzuki bits, though.

A phone is not a camera, they only do impressions.

Either way hold the tube up to the light & check for ovalisation. It may be hard to pick, harder to photo.

I was only taking a photo of my phone keypad to show how the focus should look on a macrofocus image of something small or detailed at close range... in no way am I suggesting that a cellphone makes an adequade digital camera for this sort of photography. Some are pretty darn good though, 3MP with a macro focus switch... but you need steady hands as the lens is small.

Anyway, not really relevant to the thread, so I'll shut up.
As you were...

Do you accept buttons and perhaps pieces of string?

God what I would give for a better paying job right now, I would literally jump right into a loan.

*Stamps feet*

[Bend-it]

how long?

[zeocen]

Give me a new job and the piece of string will be infinite !

[MSTRS:Me]

Give me a new job and the piece of string will be infinite !

Psst...you fool...splice together the ends of a piece you already have. That'll make it endless. He'll never know....

LOL, DC3200... I had one of those back in the dark ages as my first digital camera, you have my sympathy! Thinking back now I think "How the hell did that thing warrant a $450 price tag?!" I ended up giving mine away to my partner's father, who'd probably never buy a digital camera anyway. He's happy with it and it gets a bit of use, so it's all good. Not surprised you find it tough to good photos with it!
