Oil spitting through the exhaust of a Yamaha PW50 typically results from an overly rich fuel mixture or improper oil-to-fuel ratio. If there is too much oil in the mixture, it can lead to excessive oil burning, causing it to exit through the exhaust. Additionally, a clogged air filter or exhaust can exacerbate this issue by restricting airflow, leading to incomplete combustion. Regular maintenance and correct fuel mixture ratios are essential to prevent this problem.
