Uberscoot carb upgrade

What size is it now?

It was bought a long time ago and not quite sure the size but I think it was 15mm, that's the stock size too btw

You can go to a 16mm but it won't make it any faster until you remove the restrictor cast into the block that restricts the transfer ports.

Ya man, I got that but was a pain bc a$$holes glued it on, ok 16mm thanks

Been looking and I don’t c any that r 16mm, I just wanted to ask if the carb doesn’t specify evo, mototech or uberscoot compatible, I look at the manifold bolt spacing to find a carb that will fit? Im not great with terminology on 2 strokes so…

This carburetor kit is suitable for all stock Pocket Bikes 47cc and 49cc. The highly pressurized air-fuel mixture allows for an increased horsepower and top speed. This 16mm carburetor is specially designed for competition. The fuel inlet adapter is not included in the kit and must be ordered...

This one has been sold out for a while, I might end up getting a 15mm carb but would that extra mm b any difference? I removed the restrictor gasket and ported it a little bit, but I have gasket maker in place of restrictor gasket, I think I should buy another gasket instead of gasket maker to have the same gap so piston doesn’t hit top, I dunno if it ever hit the top though and rode it like this for a minute, I would also like to donate to this site bc this site is the only thing that has helped me in my pursuit of 35mph scooter

I run all of my engines without a base gasket...

What do u use then? Red gasket maker?

Lately I have been using Hondabond high temp gasket maker but any of the high-end silicone motorcycle RTV silicones that resist two-stroke oils will be good...
