Re: Alukit cheap DR piston replacement?

I am using the alukit piston in my hobbit, it's going well so far.

You get a different piston than is pictured there though. The ovalish hole in the side is a bit bigger, the sides of the piston have actual cutouts instead of those dip things the dr piston has (more lubrication for wrist pin?), and the rings are a little thinner.

The only downside about it is the machining on the top of the piston doesn't seem that great, still just raw casting for the most part. Pretty sure that doesn't matter much though. Besides that it's all good.

This is the guy I got when I ordered the alukit piston: http://www.treatland.tv/v/vspfiles/photos/hobbit-wizard-piston-2T.jpg

I might be opening it up tomorrow, if I do I'll take a comparison picture.

Hope that helps! (edited)
