Why does my bike not go up hills ? grubee gt2b 48cc , cns carb

I have found both my CNS carb bikes needed bigger jets once I put an expansion exhaust on them.

Looks like I am purchasing the cheap older carb .... wish I bought the crappy boygofast kit .... doesn't seem like those people have any probs w/ carb and what not ....lol

My BGF kits have the simple, easy to use NT.WH carburetor, no problems at all with them.
I think that the EPA is mandating these CNS carbs on all new shipments, better stock up on those NT carbies from BGF

If you buy in bulk, it's like $13 each:
