    I have a Norton with single round slide Mikuni and I would like convert it to use the original Amal choke lever on the bar, instead of using the little lever attached to the carb.

    I checked the archives and there is not much good info on this. I see that Rocky Point Cycle sells a kit with cable, and there is some advice about specifying a flange vs a spigot type.

    I would prefer to just buy the Mikuni bits I need from the local cycle shop, make up a cable that I know will fit, and use the Amal lever I already have.

    Does anbody have a Mikuni part number or details on how to order the carb end of the conversion?

    As the enrichener on Mikuni carbs is simply a piston which only needs to move around 1mm to work, not completely sure a cable set up is the ideal way to operate it? Nothing at all to stop you fitting a cable to it though, but as the lever mech is extremely reliable and completely trouble free, wonder why you want to do this?

    You can buy the replacment choke bits without the cable, the cable end on the choke plunger is quite small and I couldn't find a nipple, so one was formed by flaring the cable and solder.
    I find it much less fiddly to use

    It is really useful with twin Mikunis.

    Just remember that the handlebar choke lever will operate the opposite way from the Amals.

    When had Miki carb on Ms Peel I was able to configure the factory choke and cable but it always felt like the factory install - a bit too hard to move than expected from lawn mower chokes- but worked and never failed. Choke lever is a cute item on bars to me.

    I'll second the suggestion of getting what you need from Rocky Point www.rockypointcycle.com
    Put it on my Mikuni and it works real slick.

    In the UK there is Steve at Motocarb that produces a conversion kit that comprises,

    1 x alloy Magura lever
    1 x cable
    1 x cable conversion kit for the carb (£11.50 bought separately)

    £33.00 inc. + £3.00 postage
    It's very simple to fit and includes an instruction sheet.

    Third for Rocky Point's nifty, nifty kit! The kit makes it easy, comes at a good price, and it works great. Never look back fondly on reaching under there to mess with that lever.

    Probably my favorite conversion... But I don't have many (aside from the carb)...

    I tried to buy Rocky Point's kit, but they don't do Norton stuff any more. I ordered the Mikuni choke cable conversion kit WP-13-0200 and a single choke cable for a '68 T100R. I had to file a mm or two off the cable end to fit it into the plunger, but it was really easy to assemble and works well. Of course, the choke lever now pulls the cable instead of pushing it.
