Thanks for the jetting info, currently running a 36mm which is stuffed, i might try a 38mm and see how it goes.

the difference in slides, if you go from a 210 to 220, will the 220 have more cut away on the slide or does this change the deck height where the needle sits?

Does any one suggest that with a good set up  the mikuni is a match for the
Bing that is correctly set up for a 400 AW Maico for scrambles??

Gooday Neil, Wulfsport in England is a good contact for a new Bing if you go that way, 38mm Bings are very rare in OZ. The no on the slide ie; 210 is a richer slide than a 220 a 230 is leaner again has no other effect on the carby that I know of. Personally, I would run the Bing all day long on a Maico. Good Luck

I've got a 38mm Bing on my 350 square barrel....It was, I think off a Husky. Without pulling it off I can't relate the jets but remember that it's got a 185 main. One thing about Bings is that they're not as finicky as Mikunis with jetting changes. Get it right in the beginning and you'll rarely have to touch it again. Give me a Bing any day of the week....one my still end up on my piston port RT1 Yamaha engine yet.

Hi Firko, I am still trying to get a new Bing 54 - 38 for the Maico, I have tried the Bing guys and a couple of others.
they want the numbers from the body of the carby, which I don't have for a 38mm carby.
Any ideas where I can look up the part numbers for a 38mm Bing? Neil.
PS I have a 74 - 400 with a mukini fitted to it. it starts easy, hot or cold. its a bit like kissing your auntie!!
just doesn't have the same zing as a good Bing on a Maico.
