What maintenance challenges have been linked to increased emissions in Alsvin owners?

Have users reported delayed oil changes, clogged air filters, poor spark-plug condition, injector fouling—or DIY maintenance mistakes—as underlying causes?

Common maintenance-related causes:

Delayed oil changes → increased blow-by gases.

Clogged air filters → rich mixture, black smoke.

Worn spark plugs → incomplete combustion, higher CO/HC.

Injector fouling → rough idle, high HC.

DIY mistakes:

Using the wrong grade of oil.

Tampering with the intake.

Installing aftermarket O₂ sensors incorrectly.
