Honda NSR250R Engine center Gasket - 061A0-KV3-407

This is the genuine Honda main crankcase center gasket (often associated with the 061A0-KV3-407 service set). It is the critical, large-format seal that sits between the two halves of the NSR250R engine crankcase, ensuring the integrity of the primary compression chambers and transmission housing. Vehicle Compatibility & Year Fitment Model Compatible Years Honda NSR250R (MC21) 1990–1993 Honda NSR250R (MC28) 1994–1999 Technical Note: This is the large "center-split" gasket. Because the NSR250 is a V-twin two-stroke, this gasket is shaped to maintain the specific crankcase volume required for proper engine performance. 4. Fitment & Installation Details This gasket is the backbone of the NSR250 engine rebuild. Because the two-stroke crankcase relies on primary compression to pull the air-fuel mixture into the cylinders, even the smallest gap or tear in this gasket will result in an engine that runs erratically or suffers from a total loss of power. When you split the crankcases, ensure you clean every trace of the old gasket material from both mating surfaces—if you leave even a tiny bit of the old seal behind, the new one will not sit flush, and you will have a leak. Do not use excessive liquid gasket or RTV on this part; use only the lightest possible film of a non-hardening sealant (like Yamabond or ThreeBond) to ensure the surfaces are perfectly mated without blocking any of the oil feed galleries.
