150mm conrods?

[bozothenutter]

Anyone on here running them? (With corresponding pistons ofcourse!)
What have you got, for what use, how many rings does the piston have?

I was looking at these for a monster F4R build but stuck with 148mm as CP pistons won't fit 3 rings with 150mm rods and Nick from PMS didn't recommend using a 2 ring piston. Not sure if anyone else makes a 3 ring piston that would work with 150mm rods, maybe try Pistal in italy

Did you go with their pistons too?

Any decent piston manufacturer can get around the issue of 2 piston rings. You just have a blanking piece that fits in over the gudgeon pin so you can run 3 rings.

Seen it done and it works.

Wössner make a long rod kit (K1550DA), with the catalog stating it's a three ring piston.
Can't really check, as there are no images available, but the corresponding ring set (827XSY-3) seems to be a 3 piece affair.
