Banjo Bolt problem!!

06 S2R 800....
I am trying to undo the clutch banjo bolt to fit risers, it is really done up tight!!; it does not appear to be an exact fit for my sockets!
Are the bolts metric or imperial? 11mm is too small and 12 is slightly too big....

Cheers,
Jim.

It should be metric BUT.....

Thx......I thought it should be, maybe I need a better socket???

Try a hex socket rather than bi-hex, or a good ring spanner.

Thx, I will try that...

Cheers,

Some aftermarket bleed nipples, such as the 'speedbleeders' often have a US size. The one on my 916 clutch slave is 5/16 and the rear brake caliper 3/8 UNF.

Thx. I thought it might be US/imperial (dont know if they are the same?), 15/32 seemed to be the closest match.
You would think a Ducati would have metric bolts.

They mostly do but there are some exceptions, at least on older models; the 'bung' in the exhaust for gas diagnostic and quick-release fuel tank fittings being a couple that spring to mind.

The speedbleeders are made in the USA and use non-metric sizes, probably because they originally made them for Harley-Davidsons and then went on to make them for other bikes and use the same material despite cutting a metric thread.

Actually the US size bleeder on my rear caliper is better IMO, because the Brembo part is bigger (11mm IIRC) and it's a tight fit to get a ring spanner on it because it's so close to the brake line banjo but the speedbleeder is around 1.5mm smaller so a ring spanner fits easier...
