Topic: VM carb gurus?

[turboguzzi]

Preparations for coming season going ahead, managed to sort out a nice, vintage legal brembo setup instead of the good old hinged honda calipers, 4 lbs of unsprung weight saved! will post pics soon

back to the topic, I am also doing a poor man's CR carbs version by boring an extra set of 27 VM ou to 29 mm. Trouble is that now I am coming to realize that the stock needles are going to be a bit too short with the extra 2mm stroke of the slides....

Does anybody have an idea what needles coold fit? BTW, these are not smoothbore VM's so I need the so called short needles.

any advice is welcome

cheers

It's just a little tougher getting a cheap set of 28's!!

[turboguzzi]

exactly what i was going to say! 28's might be more common in the USA but then I'd have to ship that big lump and pay customs, they are almost impossible to find here in italy.

In any case, dont care much for good idling as this is a race bike. eccentric boring (like they used to do on 28mm RD350 carbs) will weaken on side of the carb stub too much, so I am stuck with concentric boring. if it doesnt work then I've thrown the 50$ they cost me in an autojumble.

guess it's time to learn the mikuni needles sizing system and see if sudco's got something that'll work.
