I have a 90 ktm 250 the stock calls for a 175 main but it has a 185 main in it now, i'm running 32:1 right now and i gurgles at 1/4-1/2 throttle but runs good after that. it spooges like crazy too. What do you think?

1/4-1/2 throttle position is using the pilot jet/needle. Try raising the clip on the needle and see how it is. Try going leaner on the pilot by 1 or 2 sizes and leaning out your air screw 1/4-1 turns out from stock.

Also a 185 main jet does seem pretty big, you could go back to the 175 and see how the spooge is.
