Tappets Adjusting Screws

1 products

Our range of Tappets Adjusting Screws for Harley-Davidson covers the precision adjustable tappet screws used on 1915-1973 45 inch, 74 inch and 80 inch Flatheads, 1952-1956 K and KH models, 1936-1947 Knucklehead and 1948-1965 Panhead Harley-Davidson engines fitted with OEM solid lifters. Iron City Motorcycles in Leeds is an authorised Harley-Davidson dealer, and tappet adjusting screws are the precise threaded components that set valve-train clearance on a solid-lifter vintage Harley-Davidson, where incorrect adjustment leads to a noisy valve train or dropped valve clearance altogether. You will find MCS's workshop-standard adjusting screws and S&S's performance-grade valve-train hardware, giving you options from OE-specification restoration through to blueprinted performance builds. Whether you are restoring a Knucklehead, refreshing a Panhead top end or completing a 45 inch Flathead rebuild, the correct tappet adjusting screw is here. Browse the full range below.
