Can any one advise a good way to replace or have made a emulsion tube for the twin carb set up on my xt 600 e
the yamaha chap said it needs replacing , the bike runs very rich just of idle spurts and farts quiet spectacularly

The emulsion tube just unscrews from the carb body, it's the main jet holder.

They're about £25 in the UK, no idea what that is in Au$.

If it is your emulsion tube it'll be the one in the left hand carb, personally I'd get a 2nd opinion, spurts & farts tend to mean you're running lean.

EDIT: Pops & bangs from the exhaust mean too lean, spurts & farts from the airbox are a rich mixture.
I'd still get a 2nd opinion though or better still take the carb apart yourself & have a look for wear, leaks & check the settings :thumb:

P.S. :welcome2:

P.P.S. A Mod probably will come along at some point & put this in the right section :shades:

The emulsion tube in conjunction with the needle performs the vital function of providing the metering and mixing of fuel and air from 1/4 throttle to 3/4 throttle.

Movement and vibration cause the hard needle to wear the soft brass of the emulsion tube and the precise metering goes West. :sherlock:

Any bike with more than 50,000km will most likely need a new tube. :oilleak:

Do yourself a favour.......it'll run like a new one. :shades:

Carb is fixed with no need for the emulsion tube , the diafram that controls the idle and sits on the side of the left side carb was blocked [ brown residue from 27 yrs of build up ] the shut off causing the over rich idle and eratic behavior
found a mechanic [ actually the bloke i originally purchased the bike from ] who knows of such evils and put us back to the land of happy campers :star: :star:
