Keep your J-Series 350 engine perfectly tuned with the genuine Royal Enfield 1570554/B Tappet Adjusting Screw (Elephant Type). This OEM screw allows precise adjustment of valve clearance, ensuring smooth valve timing, reliable compression, and quiet top-end operation. Over time, adjuster screws can wear at the contact pad or lose thread integrity, making accurate adjustment difficult.
The 1570554/B screw is used across all Royal Enfield J-Series 350 models: Meteor 350, Classic 350 Reborn, Hunter 350, and the new Bullet 350. Both intake and exhaust valves use the same part number, so you will need two screws for a complete replacement.
Replacing with a genuine OEM part ensures correct hardness, factory-spec threads, and precise geometry. This eliminates valve ticking, improves long-term reliability, and prevents damage to rocker arms and valve tips. Always reset valve clearance to the recommended spec after installing new screws.
