EX-500 Carbs: Spring Length?
- Thread starter DirtyErnie
- Start date
Measured today spring length 100mm, dia of coil 15mm, wire 0.6mm diameter. What are you up to?

Tweeking. I'm off the map trying to get needles to tune up, bike wants a leaner taper than is available. Maybe I stretch the springs if they're not up to spec, add a little more pre-load, slow down the needles a bit.
Been through the EX500 carb thread??

Oh yes, so many times.

Think I found the issue: My springs are 80mm long, 14.8mm diameter, 0.7mm wire.
Carb ID#: V334DB15
Do I start stretching until things work with normal needles, or just order some replacements?
Thanks for measuring!

On the EX500 forums there are lot of carb rebuild threads. I found one that was by Ducatiman, someone who sells parts and offers a rebuild service. They may be able to provide the correct springs.
Here is a link to his rebuild thread.
