Duccrazydave-
I traced my carb problems with the Mikuni's to the jet needles being machined like little rat-tail files and they wore the needle jet orifices into a egg shape. They were from a "Factory" carb kit if memory serves. By that time I had had it with the Mikuni's and sprang for the Keihin's. Immediately I was getting 7-8 more mpg and I think I just had one main jet change to get them dialed in better than the Mikuni's ever were. The down side of the Keihin's is that they have no choke but they have accelerator pumps so in colder situations it can be hard to start. Add the aluminum flywheel I had installed and I had to "catch" about 3000 rpm at start to keep it running at first start. Bet the neighbors loved me.
I changed the rear shock to an Ohlins pretty soon and did spring and valving changes to the front later on. I do remember that working on the upside down forks was a real PITA! Even with dedicated tools.
Love, dogged determination and insanity pretty well sums it up!
