Cylinder Head Reconditioning

Head Reconditioning

A good maintenance program is a crucial part of any off road bike or ATV's life span. Internal engine parts begin to wear the moment the machine is first started and continue to do so until they eventually break or wear out. Maintenance is all about finding these inadequacies and repairing, or replacing them, before they cause major problems. An often ignored part of your engine is the cylinder head. Let's face it, four stroke cylinder head and valve train maintenance is not going to be tops on the list when the sun is shining and you want to go riding. Unfortunately, poorly maintained valve trains have a way of ruining very expensive engine parts. When valve heads wear and start to mushroom, performance may not be the only thing you're loosing. Valve faces do not wear evenly once they begin to mushroom. Deflection will occur every time the valve face makes contact with the seat. This deflection causes rapid seat and guide wear and if not serviced, will eventually cause the valve head to snap off and fall into the cylinder. Ouch! That's going to leave a bruise. For this reason, your maintenance program should include cylinder head removal, disassembly and inspection at least once per year. Take short cuts and you could end up with something that looks like this!
