What Musky said, the 180 or the 185 main jet, pilot jet back to stock 35,needle on 5th slot and set the PMS to 2 1/2 turns out. Do the WOT to see if the main needs to be changed. You may have to move the needle up to the 4th slot. To fine tune the PMS screw it in till the engine start to stumble then slowly screw it out counting the turns till it starts to stumble, screw the PMD back in half the turns that you counted. Ride and note the way the bike runs then tweak the PMS in or out 1/8 to 1/4 turns until it runs the way you think it should. The DJ 185 is closer to the Mu 172.5 that I am running but the 180 my be where you need to be. I suggest you go to Radio Shack and buy a package of phono plugs and take the rubber boot off one and place it on your PMS tower. I had my PMS out 4 1/2 turns and did a lot of adjusting and the PMS viberated out on the highway and went Bye Bye. It is hard to get home with no PMS. BTW carry a small screwdriver with you at all times.
