first run aftr rebuild 92 sl 650
I finally got to take my 650 out for its maiden voyage after my rebuild. she ran great has good top end, but acceleration is not even close to my 750. I didnt try but it felt like you couldn't whip it around if you tried. I took it easy on her until the tank was almost empty. any suggestions on the acceleration. I have 85's in the carbs and am running premix. do i need to open the screws more? they are set to stock and turned a little farther for the premix as i read on here. I don't remember the exact screw settings as it been 8 months or so since i did it. any help would be greatly appreciated.

photo is mag far right, center in center, rear far left
The mag plug was nice and clean looked good the center was a little darker brown looked more burned on and the rear looks very dark and burned on. the rear came out the driest of them all.They do not look like i am used to with my 750. what should i do? more fuel, less fuel ?

from what i read if the plugs are clean then you are rich with fuel. so it looks like 1 is rich and the others are lean?? is this correct?
