Product Description
The RE-19 valve kit by Varroc is an OE-standard replacement for the heavy-duty Cast Iron engines. Unlike the newer UCE valves, these are specifically weighted and sized to handle the lower RPM and high-thermal cycles of the vintage CI head.
Manufactured using high-strength Stellite-faced steel or equivalent alloys, these valves are designed to resist “pitting” and carbon buildup. The set includes one Inlet Valve (responsible for air-fuel intake) and one Exhaust Valve (built with higher heat resistance to withstand exiting combustion gases). Replacing these is essential for solving issues like poor starting, low compression (air escaping from the head), or “tappet noise” caused by worn valve stems.
Key Features:
-
Vintage Engine Optimization: Perfectly matched for the 350cc Cast Iron cylinder head, ensuring zero clearance issues with the piston.
-
Heat-Treated Surface: The exhaust valve is specially treated to prevent warping under the extreme heat unique to the CI 350’s combustion chamber.
-
Precision Stem Diameter: Designed to fit exactly into the bronze or cast iron valve guides (Part No. 140925) without excessive play.
-
Direct Replacement: Replaces the original RE Part No. 597405 (Kit) or individual parts 144448 (Inlet) and 144449 (Exhaust).
-
OE Quality: Produced by Varroc, a trusted tier-1 supplier for Royal Enfield, ensuring factory-level durability and seating.
