Is your Bashan 250cc ATV (like the BS200S-3 or BS200S-7 models) hard to start or running poorly? A fresh spark plug is often the simplest fix! This is a standard D8TC spark plug, a common type for many small engines and Chinese-built ATVs. Supplied by HMParts, it's a direct replacement for the original plug. Swapping out an old, fouled, or worn spark plug can restore crisp starting, smoother idling, and better fuel combustion. It's one of the most basic yet important maintenance items for any gasoline engine. Keep a spare in your toolbox for the trail. Easy to install with a basic socket wrench. If your quad has been sitting or is used hard, a new plug is a cheap and effective way to improve performance. Made in China. Keep your off-road fun running reliably!
