Does anyone have any experience of or can point me in the direction fitting Mk2 Amal Concentrics to a 790cc Bonneville?

The idea is we want to splay the carbs by angling the rubbers or mounting spigots and fit either bell mouths or small filters.

We dont really want to use the existing carbs because of the choke linkage etc that binds the carbs together.

Any technical comments would be appreciated.

Dinqua has some pics on his site...not sure if there's details on the conversion, but maybe you could email him.

Norman Hyde in the UK had a kit he was selling for a while but it doesn't appear to be on his website any longer. I believe Peter Jenks (late of Jenks Bolts) had some input and tested it on a 790 Bonnie on behalf of Burlen who now own the Amal brand. Apparently they didn't work too well and needed more development. I suspect that development never happened and Norman canned the idea. I kind of got the impression that the quality of the carbs wasn't much better than back in the day when Concentrics were fitted to the "original" Bonnies and they tended to be a bit troublesome. If you email Norman he might help you out with some advice - http://www.normanhyde.co.uk/contact.php

Probably better than the Amals but I'm not keen on the split throttle cable compared to the direct linkage on the stock carbs - harder to keep syncronised. Seems a lot of money just to spend for looks as the performace couldn't be any better than an ARK with stock carbs. Does look good though.

I can understand you wanting to go for that splayed head look, but do find some better carbs than Amals. They were rubbish back in the day and they haven't improved any.
