Rowe’s “Tru-Bore” cast iron valve guides are made from fine grain, heat treated cast iron. The outer diameter has been ground between centers for concentricity. Cast iron has good self-lubricating properties and is easy to machine. Sold each.

For the engine tuners that want ultimate performance from their ported and flown heads, Precision Machining designed special shaped valves with oversized heads and extra long stems. These high performance valves are available in various materials. Exhaust valves have the patented 44 degree tulip angle for improved flow and higher gas speed. Stems need to be shortened to required length and keeper grooves need to be machined. These valves are a must in every performance shop.
Note: These are not stock replacement valves, they require machining by a professional with professional equipment.
Sputhe Nitralloy Big Bore cylinder kits for Evolution Big Twin are obsolete now, but we still have some replacement parts available.
These Wiseco Big Bore kits are developed for Twin Cam 96 (1.550cc). The use of the 3 7/8″ bore pistons with stock 4.375″ stroke enlarges the capacity of your Twin Cam engine from 96 to 103CI (1.691cc). The 4″ bore kits will even give you a 110CI displacement (1.802cc) but must be used with the use of cylinder sleeves in your stock cylinders. The 3 7/8″ bore kits can be used in bored-to-size stock cylinders. Sleeves are not included but must be ordered separately. Big Bore piston kits contain a pair of Wiseco forged pistons, a Hastings ring set, chrome wrist pins and circlips.
The S&S cam-drive oil pump system (S&S 31-6503 & 106-3887) is obsolete now, but for those who have one that has a reed valve crankcase breather (S&S 31-2093 or 31-2094) we still have some replacment parts available.
Cover those unsightly cam adjuster bolts with these designer accents. Engineered exclusively for the Victory motor. Come as a set for the front and rear cylinder cam adjuster bolts. Handmade in Spain by Black Duck.
Direct replacement for the OEM side covers but, unlike the stock covers, bolt-on and not snap-on. Hardware for easy installation included and sold in sets for left and right. Handmade in Spain by Black Duck from 100% high quality brass.
Kibblewhite’s 7mm valve stem conversion for 1986-2003 883 Sportster is obsolete now but for those who have one we still have some replacement parts available.
Kibblewhite Precision machining valve guides are made from the highest quality materials available. Each individual part is inspected during each machining operation. Outside diameter is precision machined between centers to ensure concentricity. Each part is clearly identified to facilitate easy storage. For each type of engine there is an extra large “Repair Type” oversize guide available. Inside bore diameter is .001″ smaller than the valve stem diameter and must be reamed to size for a perfect fit and long life. C630 is a blend of copper, nickel, and aluminum. The high copper content gives excellent thermal qualities, the nickel makes the guide tough and wear resistant, and the aluminum brings work hardening characteristics. This bronze alloy allows for tighter clearances than other materials, creating better valve and seat sealing, as well as superior oil control. The expansion qualities of C630 bronze make it especially compatible with aluminum cylinder heads.These superb guides are the best money can buy. Sold each.
