Joe, the led lights from ADVMonster aren't really suited for normal street use since the output is so high, and the light pattern is so spread out. At least not the Model 44 / 60 / etc. Their H4 bulbs on the other hand, are getting really good reviews. If you look around my GS450 thread, you can see the light output from the model 44 light.
Now about those VM34's ..... I love them on the GR. They use the stock intake boots, but obviously need a 2-1 throttle cable. And it's easy to find the jetting for them since guys have been using them on XS650's for years! Matter of fact, when I was searching for jetting info I kept coming across Tim's XS650 here on DTT. I did block off the swirl ports, but just used some vacuum plugs from AutoZone (they do need replaced fairly often though because of the heat from the engine drying them out).
