Why my Yamaha FZ exhausts too much smoke?
There may be many reason of excessive smoke from exhaust like:
• Starter plunger might be stuck open.
• Air cleaner might be clogged
• Oil level in carburetor might be too high.
• Air cleaner duct might be loose.
We advise you to take your scooter to your local Yamaha service center as they will thoroughly check your bike and fix the problem.
