What is the clearance of the piston to cylinder, when boreing out a Sachs cast iron cylinder to 152cc.

Thanks

Penton Talk / Sachs sleeve replacement?
Last post by Carl Hill - April 17, 2025, 01:56:23 PM
I've changed a lot of sleeves on Japanese machines, usually drop right out after heating them up. Not having any success heating this Berkshire cylinder. Am I missing something?

Nice vintage rig for someone. Looks in good condition. Roll your Pentons out of that one!

That's exactly what I am doing. I put a set on my hare-scrambler. Need some for the 100 and 125 now.

Carl,

I purchased a few sets from Andre Horvath last year and they work great.  I have since added them to most of my CMF bikes.  Depending on the frame of bike you may need to trim or bend the end of the spring slightly otherwise they are a bear to install.  Below are links to the left and right side springs.

Thanks Carl, that will be great.  If 50 folks bring 2 machines, we will have one Penton for each of John Penton's 100 years ! AND, one heck of a long row of Penton Sportcycles...
