APE CYLINDER HEADS


Cylinder head work at APE is done on the latest state-of-the-art equipment. We have facilities to completely rebuild all motorcycle heads. As a manufacturer of high-performance cylinder head components, we have all of the parts in stock: bronze valve guides, stainless steel valves, valve springs, titanium retainers and more. Everything we need to complete your job without waiting on the parts - which slows down most shops. The only exception is our porting department which is always backed up. If you are in a hurry for porting send it elsewhere. If you want state-of-the-art work with reasonable turn-around, we are ready to serve you.

We also operate a complete aerospace-type CNC machining facility in which we manufacture our world-famous racing products. These facilities are all on-site at the APE race shop. Besides the head services listed below, APE also offers:

Complete Machine Work Service
Crankshaft Service
Transmission Service

APE provides online pricing as a service convenience only. These prices are not binding and are subject to updates without notice. Though we try hard to maintain accurate up-to-the-minute pricing it is best to call APE and check with the desk for pricing if you have any questions.

APE's super state-of-the-art Serdi cylinder head machine, with triple-float head for the most accurate valve seats possible. The Serdi uses a multi-angle carbide cutter that has the seat shape ground into it. This ensures that all angles are exactly the same - all seat widths are exactly the same. A perfect valve job.
