TT250 carb options

mtiberio · 01-25-2017, 07:17 AM

Would like to go with a carb that has a proper enriching circuit, not choke. This would be for top end performance. Want to retain the stock airbox. Also looks like the engine end of the carb has a flange, not a spigot, what options work there?

Does anyone have a link to a carb that is "bolt on" or nearly so? Genuine (japanese) Mikuni or Keihin are desired.

Thanks,
Mike.

Hey, Mike. You could try a CV carb, which is typically found on GY6-based engines. They have a minor delay due to the vacuum slider, but they have a proper enriching circuit. You could try this for mounting: http://www.ebay.com/itm/Mikuni-Rubbe...dYEBEF&vxp=mtr

That one might be too big, I think the bolt holes on our most of our Chinese engines are only 48mm apart, the item linked above is 57mm between bolt holes... I would check all sizes on your bike and email the seller asking for sizes before you make any purchases

Very good point; I failed to consider the bolt hole distance. Nevertheless, there may be an adapter out there that would allow a spigot-mount carb on a flange.
