WQSING Top End Kit Yamaha Blaster 200 YFS200 1988-2006 195cc 66mm OPEN BOX

OPEN BOX, Grade A — No sign of use or damage, all pieces included.

Overview

Give your Yamaha Blaster 200 ATV a fresh lease on life with the WQSING Top End Rebuild Kit, purpose-built for YFS200 models spanning the full 1988–2006 production run. The kit centers on a 66mm bore cylinder matched to a 195cc displacement, restoring the factory compression and power your Blaster was designed to deliver. The photo shows the finned cylinder head component of the kit — a precision-cast aluminum piece with deep cooling fins and machined spark-plug and bolt bosses that demonstrate the quality of fitment and finish throughout the set.

Why Rebuild the Top End?

Over time, piston rings wear, cylinder walls develop scoring, and head gaskets lose their seal. The result is lost compression, harder starting, excess smoke, and diminished throttle response. Swapping in fresh components from a complete top-end kit addresses all of these symptoms at once and costs far less than sourcing each piece individually. With everything engineered specifically for the YFS200's 66mm bore and 195cc displacement, you get a direct, precise fit rather than an approximate match.

What's Included

• Cylinder (66mm bore, fits 195cc configuration)
• Cylinder head
• Piston with wrist pin and clips
• Piston rings
• Complete gasket set (head gasket, base gasket, and associated seals)

All pieces are confirmed present per our open-box inspection — nothing is missing from the original kit contents.

Installation Notes

This kit is suited for experienced DIY mechanics familiar with two-stroke ATV engine rebuilds. Proper torque specs, ring gap measurement, and cylinder honing (if reusing the bore) should all be verified against your service manual before assembly. If you are new to top-end rebuilds, professional installation is recommended to ensure correct assembly and long-lasting results. A quality rebuild with these components will restore strong compression, crisp throttle response, and reliable starts — mile after mile on the trail.
