Question about 2003 Yamaha YZ 450 F

1 Answer

YZ not starting

Ok so the other day it was cutting out in the higher gears. It would cut out for a second then kick back in. Then I went riding today and it was doing it, so i let my friend ride it, we stopped and talked about it. When i went to start it up it just wouldnt. SO i brought it home and put a new plug in it and it wont start up. Dosent even sound like it wants to. What could be the problem ?

I don't think this is a float issue. One way to check is to turn the gas off, take the bowl off the carb, hold the float up, and turn the gas back in. If fuel flows, the float needle is toast. It sounds suspiciosly like a worn topend, but it could also be a clogged jet ot fuel filter, or a faulty CDI.

Yz 426 while riding it i went to park it thought it was out of gear and let out on the clutch and it died went to start it back up and the kick start seemed to b stuck so i rocked it back and forth fi


How does the compression feel now that you have it cranking over again. Without the decompression lever pulled in it should be next to impossible to kick it over. also, is there any noise coming from the engine (knocking, etc.) when you got it to start again.

My yz 125 started to bogg down when i put my bike in 3rd gear and i drove it back the next day i went to wash it and i tried to start it. it started but bogged right down till it shut off no matter where...


Ii sounds like your bike cuts out when it get`s hot ? If it does this like clockwork then i guess you have same problem as me with my no limit 125 which does exactly that. i have fixed all connectors & cdi but it still does it. Which leads me to believe some ferrite core in the ignition system is going non-magnetic (called the Currie temp) at this "hot" temperature. It can either be the magnets in the flywheel or the core of ignition coil.I only use this bike for trips less than 10km so i live with it. if anybody can shed more lite plz!

Engine seized?


First thing to do is make sure it's the kick starter that has seized and not the engine. Take the cover off the end of the crankcase and try to turn the crankshaft. Apparently these engines were notorious for doing bottom ends. Start pulling it down and see what you find..

Kick start is jammed


Put the bike in 3rd, 4th or 5th gear, the higher the better. Sit on the bike, with your hand off the clutch lever, and rock the bike back and forth to rotate the clutch hub. This might free up the lever. You will need to drain the oil and remove the right side casing to see and service the kick starter. If I recall correctly, there is a spring clip that allows the kick gear to engage the clutch hub. The piece could be broken, weak or out of position.
