I'm guessing that it was a dynojet kit now that I think about it. I may just have to go with plan b, and go through a handfull of used jets untill I find one that fits.
You could go back to stock with an HD emulsifier tube, jet and needle. However, if it is a Dynajet Thunderslider Kit in there now, there is much more to change to get back to stock. Might not be worth it. You may be able to order a larger main from Dynajet or their distribution channel. See the bits here:
