DR cylinder

[Mr_Bub400ex]

i was reading an old dirtwheels and noticed a duncan ad for a 400ex cylinder that you could get in any size up to 450 and was Nikasil coated and had better stud capabilities. has anyone used this thing? would it be a good idea?

I called duncan racing and they said they will only sell you one with their pistons. They won't sell you just the jug. He said it would be around 1000 dollars for the kit.

I wanted it for the curtis sparks 465 92mm piston-but oh well.
