lean cylinder 1977 KZ 1000

I picked up KZ for cheap (not running) first thing I did was clean the
carbs, second put in a battery...it fired right up. I fouled the plugs
right away so I replaced them and it ran ok, it was Idling high and
loading at the stop lights. I pulled the carbs again and mechanically
synched em, this helped alot. It idles very nice and the entire power
band is strong, but through the whole process the # 3 plug comes out
pure white and the others are tan to black but not too black. I have
read a few posts about valve problems and I have the service manual,
but I would like to narrow it down first. Any advice would help. Oh
yeah I love the bike, I have wanted one for years, it's in very good
shape the miles say 6700 looking at parts the bike it might be
true..others not.

does that one have constant velocity carbs on it/
if so, check carefully for a leaky diaphragm in it.
i had a similar problem with a different model and make.
