Title: Carb balancing - stupid question ......
Post by: SPR on September 21, 2022, 05:24:02 AM
Morning

Before I balance the carbs ... a question about connecting an auxillary fuel tank.

The 500 has two fuel pipes whereas the 550 had one .. do i need to feed fuel to both pipes using some sort of Y connector ?

Yes I know - basic question :)

Thanks

Simon

Yes, I use a Y piece. The 550 has a Y piece down stream of the tap

Bearing in mind the flamability of petrol does anyone make a safe auxilliary fuel tank at a sensible price?

Any links or tipe welcome - something like this?

I've used a couple of Sealey MS209's for years, and they're a decent bit of kit. Nice thing with this is you can extend the supply pipe slightly and hang the tank higher give the carbs a bit more 'static head' - good for making sure the float needles are definitely seated and not leaking...

then a variation of those in 6 & 8mm so I can swap to various motorcycles

I gather then James you use 2 reservoirs to feed the twin pipes instead of using a Y splitter?

Why not strap the tank to the buddyseat and use extension tubes? You have to remove the tank anyway.

For longer than I care to remember I've just stuck a plastic medical syringe of about 150ml into the existing feed pipes/s held vertical by stiff wire to nearest frame point.

Fill with fuel and that's enough to run for easily enough setup time.

Lol - I lost one for a while, bought a replacement, then found the orginal.
