I'm learning new things all
the time....
One can get keystone pistons and rings and one can get half keystone pistons with alfin insert. I am told
the difference is thet Keystone pistons and rings is that
the rings are tapered on both sides, where as half Keystone piston and rings
the rings are only tapered on one side. There is then an Alfin insert that sits above
the ring to take
the brunt of
the heat and pressure. Well this it what I was told..... now lets I need to hear it from
the people I trust....

Frans, whats your opinion? Which is
the best to go for?
PS: Frans, I spoke to Dean, I had a good laugh at
the way he gives uitk@ks to some of
the other people
in his office. I got a price for most of
the stuff. Can I fax it to you with my parts list, just to check if I've missed anything. I also got a price from Alert motor spares
in JHB just to do a comparison. Alert is
the okies with
the half keystone pistons and rings. As soon as
the crank is out I can get
the measurements for
the bearings and sleeves to make sure they are
the correct sizes.
