what size main jet to use on 100cc bbk?
well i heard 100cc bbk is actually 82cc or something close to it.
but anyways, i want to know what size main jet i should buy and install on my stock carb.
also should i change pilot jet also and idle jet too?
or i can leave them alone.

There is not a single set up that will work for everyone since altitude and climate are contributing factors so results will vary . I would get a jet kit like in the link to have extras to play around with and be able to fine tune it enviromoto.ecrater.com/p/4129835/naraku-main-jet-set-gy6-50

You need to get a set of pilot jets and main jets.

But... you should probably get a larger carb too.
