Weber Question- Float needle

Having stripped down the carb I'm having difficulties removing the float needle, it unscrews ok but hits the float bracket , it looks like the thin float shaft is pinched into the housing on one side, does it need to be forced open to remove the shaft?

I used a thin nail and a rubber hammer to push out the floater axle. If you push it out a bit you can grab it with some pliers and remove it and the floater.

also,it only comes out from one end,motion is from the solid end to the spit end, If you do it backwards you will need a new carb top,assuming you can find one so do pay attention :banghead:

Well thanks for the advice and I followed it closely however right at the last gentle tap the housing broke off on the split side :banghead: :banghead: :banghead: :banghead: :banghead:

Ok plan B, I have a complete 96 900SS carb setup what do I need to do exactly for this conversion to work? I have a 900ss airbox but no Paso airbox as the weber came with a K&N air filter. I know the SS won't fit but what alternatives do I have and do I need to rejet?

oh no, sorry to hear that. On which side did you tap ? The split side holds the point of the axle so that is where you should have tapped with a nail. It says in the Weber manual "Always remove pin through solid boss not split one". Should`ve mentioned that. :(

The SS airbox won`t fit into the frame so you would have to use filter pods or modify a Paso airbox. What you need is described in the FAQs. I.e. accellerator grip + cables, carb manifolds from a 750 SS or Monster. The ones from a 900 will work, too if you don`t use an airbox as they are longer so the carb will stand slightly twisted. You can try the carbs jetting. The one of the 750 is a little different but at the end the jetting will depend on your airfilter setup, exhaust etc.

Thanks but I went the other way with the nail.. :,(

I see that the manifolds are indeed longer from the 900ss, so if I use those carbs what type of airfiler works best if no airbox can be used? just a regular K&N

I also have the Bollenbach 750 that I bought earlier in the year, I need to look at that setup...maybe today

Corse,

Uni Filter do some great aftermarket filters/pods to suit the SS carbs.

That's what I use, they are good.
Cheers,

Fraser.

It is always best to support the holder with a block of wood,or learn to cuss in Italian.....guess I should have mentioned that,but then again it does not take a lot of force to change it live and learn ducatista :banghead:

motion is from the solid end to the spit end
and you should have mentioned that this is when assembling not removing the floater.

Here`s a complete Weber on ebay. Rarely some are offered for less but mostly they are more expensive

UniFilters are nice, I have some, too. The only thing I don`t totally like about them is that they are made of a single layer foam. Some others have a double ply foam with a rough and a fine pored layer which may filter fine dirt better.

I was gentle with it too and took the advice to go that way! oh well its a good excuse to dump the weber anyway...

I noticed my Bollenback is fitted with 38 FCRs I have not ridden it yet and wonder how much better it will be?
