I'm fine tuning the vm36's on my 650. It runs fine and starts good but is a little rich at idle. I have two sets of carbs from 650s to scavenge parts from plus my jet box. Anyhow. The needle jet in the bike is a 0-6 and the spare set has Q-5. Are the 5's leaner? The needle on the bike is 6h9 and the spare is 6h4. Idle jets were 20 on both sets with a 1.5 slide in both sets. 180 mains on the bike and 170 in the spare. Ive dropped the pilot to a 17.5 on the bike but haven't ran it yet to see if it works ok. Im hoping it'll compensate for the slide cutaway. The bike is used on 1/2 mile dirt tracks and rarely goes much below half throttle if l ride it rightthanks
