According to the manual the 450 and the 550 came with a 182 main jet! To meet emission regulations in certain countries the bikes were jetted pretty lean I guess. Biggest difference is needle position and main jet. You can go bigger on both, a 550-setting (main 182, needle 6th from top) should also work on your bike!
But your carb is Keihin FCR-MX 41? Otherwise the jetting is different of course!

No, I don't buy that, the Yams and Suzukis were just the same. they were as rich as they could get them. the MJs start at about 130-140 and stop at 190-200 and they were all putting in 170-180s.

there nothing lean about them. they were that rich they used an air bleed to stop backfiring on the overrun but told everyone it was all to do with emmisions.

get rid of it brucifer, get my kit. the DVT is a beautiful bottom speed and second gear needle. but it is gutless, completely gutless in 4th, 5th and 6th. for that end you want an OBE * *. the D does one end and the E the other and you can't get both.
