I hooked up my battery backwards and now that I re dis it right it wont start

Most of the time you can look up the owners manual on websites as long as you can find the kawasaki website you should be good, i had the same problem with a dirt bitke and i found there website and found the owners manual and downloaded the owners manual and printed it out. Hope i was of some help to you.

Replace it. Get a floor model at lower cost

If it didn't pop after the valve adjustment, try adjusting the valves again. Popping out the exhaust usually indicates a burned exhaust valve. The valve doesn't seat all the way around and air/fuel mixture is getting into the exhaust header on the compression stroke and igniting from header heat. The reason this doesn't happen at higher rpms is the amount of time for the air/fuel to leak it really short.

Could be dirt in a fuel jet in the carb. You cap purchase a fuel cleaner to put in the gas tank and if that does not work the carb will have to be cleaned.

have you checked /tested the kill switch

p[robably neither but a broken return spring on the selector lever

Replace the glow plugs one or more are shorted

Try more!

hi mate replace wires/cables and put another spark plug in it could be spark plug fouling and try the cdi in another kx80 also replace hd lead from coil to sparky

This is most likely because you have it in gear going down hill with the throttle closed. This turns the engine into an air brake, and the sound you hear is the compressed air being released during the exhaust cycle.

check spark plug

I'm not familiar with this bike but it sounds like it could be air locked and causing it to overheat.I found the best way to remedy problems like this is to get it up to temp,shut off and lay bike down too one side then the other.Tilt forward then back,check to see if coolant level dropped.If that dont work pull a vaccum on cooling system and see if it holds when warm.

kfx 450 is fuel injected
needs good battery to start
not enough info to diog
does the starter turn over
is it getting spark
or is fuel pump working
need more info

try taking stater fluid to carb and try keeping it running,needle seat might have some dirt in it or the carb itself needs to be cleaned.

if you subed it there is a good chance you may have sheered your timing key. its a preety easy fix. had it happen to me once

check comprsion. check valve clearance.
