What is the internal gate port size on a GT25/28

Postby Bazda » Fri Nov 05, 2010 3:32 pm

Wanting to know the port size on an internally gated GT25/28?
Not the size of the flap, the size of the actual port.
Anyone know?

I measured mine when I had it welded up, I think it was about 28mm, but I definitely could be wrong, it was in the 20's at least.
