Wiseco FAQs

Do I need machine work for a rebuild?

Often. Cylinders may need honing or boring, and heads may need valve work. Measure first.

What causes low compression?

Worn rings, leaking valves or a blown head gasket.

Should I replace gaskets every time?

Yes. Reusing gaskets is a common cause of leaks.

How long is break-in?

Follow the part maker's guide, usually varied RPM and no full load for the first hours or miles.

Forged or cast pistons?

Forged pistons are stronger for high output; cast pistons are quiet and durable for stock use.
