reading my clymers now. stock jetting for 88 and up :pilot jet 37.5, main jet:240. needle clip 3rd groove ,needle  #6fp63 and air screw is 2 turns out . The 1985 was the only model with a 32mm carb.  .The 86 is the only model with the vm34ss mikuni  that had 45 pilot (according to my manual).Not sure how this differs from the jetting you are using right now .
 Now i have a question , judging by others "stock jetting" answers ,
how can manuals differ so much !??
