Question 1

What is the difference between the two base gaskets included?

Accepted Answer

The kit includes one cylinder base gasket that is the same thickness as the original equipment (OEM) part. It also includes a second base gasket that is 0.1 mm thinner, which can be used to slightly alter compression or port timing.

Question 2

Does this kit include all the gaskets needed for an engine rebuild?

Accepted Answer

This kit covers the cylinder head and cylinder base. For a complete engine rebuild, you may need additional gaskets such as crankcase or exhaust gaskets, depending on your specific needs.

Question 3

Can I use the thinner base gasket for performance gains?

Accepted Answer

The 0.1mm thinner base gasket can be used to increase the compression ratio slightly or to adjust the effective port timing. This is a common tuning method for experienced mechanics.
