I finally bit the bullet and got the Stroker/Mikuni 33mm pumper carb for the bike since I will have it until next year sometime. I had hoped that changing needles and jets would be easier but its pretty much the same except the jets are easier to find. I got the carb on Thursday and hurriedly rejetted and installed it for a Friday trip to KM (7,000 ft higher than home base). Once there I warmed it up and went for a real quick spin, I could tell right away that the mod was going to produce more hp and it ran fairly good with my guesstimated jetting. One big problem turned out to be that I hadn't looked at the carb close to enough to locate the air/fuel screw :( Dayum thing is hard to find and almost impossible to see or adjust once installed. Long story short I modified it this week and its a mod I will probably do to every carb I ever have!
I ended up taking a stnad-off from a PC board (aluminum) and JB welded it to the end of my fuel screw. The stand off was about an inch long so I then cut it down to about 5/8". The stand off I used was slightly larger than the scerw itself so I had to grind it down with a dremel (the fuel screw is inset into the threads about 3/8"). Next I took a lock washer (one shaped like an asterisk on the outside not smooth) and put a small screw through it and into the open end of the stand off. I can now lean over with the bike runing and adjust the fuel screw with my fingers, blip the throttle etc etc until I am happy. I will try to post a pic tomorrow. Now if I could just relocate than damn shock resorvoir.
