FYI Jeff (geoff?) The carburettor trumpets pictured MIGHT be suited to the 36PHH Solex Mikuni Carburettors pictured (mistakenly labelled as 40PHH which shares the DCOE DHLA bolt pattern) the 36PHH pattern is that of the DHLB and DCOF patterns so you may find they are not applicable to your carburettors (best to check first).

The carbs fitted to the manifold are 36PHH Mikunis on a round port manifold, any true 1000 enthusiast would recognise this assembly as the Solexcel upgrade offered post factory by (SOL) EXCEL. These seem to have been sold by the competiton department in the states but not listed in their catalogues (I think).

Here is another set for sale- mistakenly advertised for the second time running.

They are a good upgrade for round port motors. I run the DHLB variants on a round port small chamber A14 and it hauls ass. I intend to fit a set up to a worked A10 that I've had stashed.
