Question about 2003 Yamaha YZ 125
SOURCE: yamaha yz125 wont start...
hello there guys, listen a top tip is when the engine's cold tip the bike almost right on its side nearly touching the floof, wait for the petrol to poor out of the carb over flow pipe, this should take a matter of a few seconds, stand the bike back up again and kick and that baby should start right up, if it does then you have a problem with your float, if it still doesn,t then take it to a shop and get them to check it out, hope this helps. regards sam

There is a proper way to start the engine. Four controls are on your bike to assist in starting.

i dont know what all you have tried so far, but check the fuel filter, usally in the tank above petcock. the compression seems fine as you had to bump start it in third gear. you can feel the compression of a bike when pushing it in gear, like a bike with bad compression you could push in first without wheel locking

Testimonial: " lots of gas , injector cleaner in the gas, spray cleaned up carb in frame,pulled of valve cover cam looks burnt blue in colour lack of oil? valves "
Compression is too low!
Replace the piston rings.
Also check continuity from engine to frame till high-tension coil...
Check if breaker points aren't dirty ( clean out with fine sandpaper )
Check breakerpoint settings
