Pull The Petrol Pipe Off

Best To Remove Tank

There is a screw which kind of goes in the bottom of each carb at an agle, a bit tricky to get at first time as you've got to take the tank off and air box which is all a bit fiddly to get at. It is a bit easier to identify if you've got a haynes manual.

If you're going to be doing this and taking the tank off you'll be able to drain the tank by turning it upside down

Make sure you reattach everything correctly. When I had a faulty coil connection (which I misdiagnoserd as water in the fuel) I managed to leave a fuel line off somewhere, pouring petrol everywhere when I tried starting it, not that you'd do the same obviously. Good luck and a manual may make things a little easier.

You again!
If you don't have a good syphon it's best to remove the tank & turn it upside down. You wont remove all the fluid in there, but you should be able to mop out the excess with a handful of rags & a long thingy (MATRON).

The drain screws are a sod to access, especially on the front carburettor. You will need a long 5mm ball ended allen key, & a small torch to see it with. You can just see the screw from above & from the right, you access it through one of the joining brackets between the carbs. Sometimes there is a small pipe clamp in the way, which has to be carefully rotated to see the screw head.

Cheers

syringe, apply vac to tank valve and then the fuel will flow out.
