14-15 safely 16 max if you are really good. Someone correct me if im wronge. The slide leaking air is the limiting factor.

Measure the slide, and don't go any bigger. Slightly less actually.

i think harold from the creatures may have successfully bored it to around 17mm, but you need to be EXTREMELY cautious. too big and the round slide wont close off the tube completely, and it may have air leaks...if that happens, you're at full throttle full time homie!

Keep in mind if you drill that bing out to 16ish and upjet accordingly, you are gonna have problems idleing because it is so rich. If you search around here there are ways to get around it specific to that carb.
