An optimal cylinder raceway surface is a must for a well-functioning cylinder.
Even if some people think the surface still looks good, this is usually not the case, because the required cross-cut is hardly or no longer available.
The cross section has an important function, it keeps a thin oil film from the track to ensure optimal lubrication and compression.
This is the only way to have good performance and prevent premature wear.
We therefore recommend honing the cylinder each time the piston is changed and then measuring it in order to select the correct piston size.
Here's how it works:
Send us your cylinder or bring it to us personally.
We hone your cylinder, and optionally we can, if desired, deliver the right piston with the optimal size.
