bing carburetter parts?

[mr ripley]

hi folks,

do any of you guys in the trade know where I can find a reliable supplier for bing carburetter parts here in the UK

I've been to a few BMW dealers & they will only stock or order parts that are specific to their vehicles

which I find a bit odd as it means if you have a BMW & want to do some tuning then you can only order jet sizes that might be fitted to other BMW's

what I'm after are pilot jets & main jets for the type 53 carb

thanks
