Question about 2003 Yamaha YZ 250 F
Sometimes it bum starts .sometimes 25 kicks.one time i cleaned carb and put new fuel in started in 2 kicks only to go back to hard starting at riding area.bought it used seems stock.seems to have lots of compresion and when it does start it runs perfect.ihave killed a new set of boots in one summer
I used to own a yz426f and it had the exact problem... a fresh plug will fix your problem. change the plug and the bike will run great. also don't start the bike and shut it off , my bike would be fine if i started it and rode for a while getting to the proper heat range help save the plug. if my bike didn't start in one or two kicks it was usually the plug.
hope this helps
