Whats a good turning on carburetor jawa x30?

Re: Jawa x30 carb tuning

That would depend entirely on your setup.

Most people try to ditch the stock carb in favor of a Dellorto SHA or something else. Check out this article on the moped wiki: https://www.mopedarmy.com/wiki/Jawa_Tuning

What carburetor do you recommend best?

Re: Jawa x30 carb tuning

A 15 SHA is easy, but you'll have to fab up an intake. See the wiki article.

Re: Jawa x30 carb tuning

Not if you can't fab an intake.

Get used to using the stock Jikov carb. I'd start with the stock jet, and tune appropriately. See https://www.mopedarmy.com/wiki/Fred%27s_Guide for general troubleshooting.

Re: Jawa x30 carb tuning

What is the diameter of the intake on that engine? I think it could be around or under 10mm. If so, cramming all that air from a 15mm SHA could be a tuning nightmare. You can get an SHA adaptor for Jawa 210 intakes and install a 12mm Bing. Works great on my 207

Re: Jawa x30 carb tuning

The stock intake gasket has a 14mm ID hole. Haven't measure the cylinder yet, though apparently the 210 (which has better porting) intake port is 18mm diameter: https://www.mopedarmy.com/forums/read.php?7,2033670
