I like my dynojet kit. I almost feel like I have to defend it!!!
I don't know what year your bike is but if it's 89-00 with a lunchbox dynojet suggests the stage 3. I would guess the 128 main would be pretty close. Heck, if you're planning on getting a performance exhaust in the future, just throw the 134 in and you won't have to rejet later. I have a slipon and lunchbox. I ended up going 134, 2.5 turns on the mixture screws, 40 pilot (pilots don't come in the dynojet kit so find it elsewhere) and I had to move the needle clip down one from where they suggested in the instructions. (cleaned up a slightly flat spot near 40% throttle)
you don't have to drill the slides if you don't want to. They have you drill and tap them to put restrictors in the holes. I guess it slows down the slide movement when the throttle is whacked open or something like that. I didn't bother.
I'm happy with the DJ kit. For the newer style carbs I have no idea if it's any good, but my bike is completely bog free, can idle along in 1st gear in traffic without using the clutch, pulls seamlessly to redline, cruises cleanly at any throttle position, and has very quick throttle response. I'm not saying to use one, I'm just saying they're not the POS everyone makes them out to be.
