Question about 2004 Yamaha YZ 450 F
I have a 2006 yamaha yzf450 and the engine cuts out while the choke is off. but when i turn the choke on it runs good but the idle is high even after the engine warms up. i replaced the spark plug but it continues to react the same way.
Adjust your idle screw on your carb so that it gets more gas just sitting there at idle. Tighten the screw one and a quarter turn and then start the bike. Adjust the idle to where you think it sounds normal. If that doesnt work check your float in your float bowl, it might be stuck in the down position. Clean with some carb cleaner spray and make sure it moves freely before putting the float bowl back on, youll have to choke it or prime the carb again to get it started. All the choke does is let in more gas and oxegen so you might want to check how far the carbs close when you push the choke back in. Is it impeading any normal carb setting. Check that too. Good luck.
