1992 Yamaha P200TLRQ (Pro V 200) Dogs then runs great, dogs then runs great.
Sometimes when I take off it runs super strong with no problem. Sometimes it dogs for a while then when it gets up in RPMs it takes off like a bat out of hell. Sometimes I can be driving along and feel it start to dog down then rev it up again and it runs great again...
We changed all the plugs, changed fuel filters, bulb stays hard, could it be the fuel pumps? What else?

more likely dirty carbs, clean/rebuild

monitor spark, timing, and fuel pressure while problem is happening, if all is good then clean carbs like JB stated
