RE: 850 DP vs dual 4's



What I know about carbs is zip, but I do recall Don Dulmage saying that if
dual carbs were correctly tuned and synched, they were superior to a single
carb. That said, I wouldn't have clue to get one carb tuned correctly, much
less two. /Butch/Ferndale, WA

I have an old jap bike carb synch tool (4 mercury balance tubes) that I 
think could be adapted just like Dvorak's piece. I spose you guys are 
right and a single carb is better performance-wise. If there's no power 
gain in duals, then what's the point? Thanks guys for all your input.
