Kawasaki Carburetors going sour??
Hello me again with 87 ZX1000a2. I was riding my bike when suddenly the my bike starter performing very poorly. Flat spots in the rev range everywhere. I go about a mile or two, come up to a stop sign, make a left and it felt like my 100hp dropped to about 20hp. it accelerate ok in first gear, but if i get on the throttle it would actually slow down. I rode the bike to my friends house...
We took the carbs off, totally cleaned them out. Inspected them, didnt see any problems with the floats-- the bowls were dirty but we could see nothing wrong. The fuel tank seems fine, gas comes out of pretty quick. Fuel filter is fine. I dont know if i should try to find a junkyard with used parts cheap*, carb rebuild kit, or MIKUNI FLATSLIDE SMOOTHBORES carbs 36mm/38mm/40mm
To be honest I dont know the first thing about carb performance engines. But i was thinking wiseco 11:1 pistons these Mikuni carbs (I dont know what size) Vance hines exhaust and just enjoy that. I doubt the carbs will do much for performance but i was thinking it would be good preventive maintence. I didnt plan on buying them this early either, i was going to save up over the course of the winter. $599 Ouch. what do you guys think??
Im going to check the compression too, but i dont think thats the problem. What kind of numbers should i see across the 4 cylinders like 170psi?
