2T Carb recommendation for future BBK  By  phatboy (Read 823 times)

Not to restrictive period at the end of the day oversized carbs a sorry excuse for scrappy jetting a good jet kit can make your carb pull as good as the new one personally I would use a Keihin 18mm.


Typical  Carb size up to 100cc is about 16mm- 19mm no bigger unless you have some sort of scoot in which you had no new top ends available and had to swap from a older product to create a bbk.


In my application I have to either switch to a stock Yamaha RIVA top end from an cv 80 or look for a  Honda aero 80 or 125. 

Upjet the main jet mainly if the piolet takes leave it a lone and do clip height if your on the 5th notch or 4th notch tdepending if it's a 4 or 5 flipper that's a sign you need to upjet after gnu I know for sure your going to need a new main though possiably like -100 depending on your elevation from sea level.


I'd wait til you slap the new bbk first then order your carb so you will have a feed start point.


Seems like your on a Bing bong scoot so you should have access to all types of clone parts.
