I have a set of stock stroke, stock bore Aggressive Dune Ported Cylinders by Wildcard Racing. These are off my 2006 banshee. The cylinders have been great for dunes and lining it up. I'm moving to a Wildcard 4mil.
They do need to be bored. I had a ring go and it gouged one cylinder above the exhaust port and wore around the exhaust port. I am told that with a .20 bore it should clean everything up. If you are interested:
Option 1: $250 Shipped for the cylinders as is.
Option 2: $350 Shipped and I will have them bored by Wildcard Racing.
If you are interested in these cylinders send me a pm and I'll send you my phone number. I want both parties to feel good about the deal with no surprises.
Also have a stock stroke trued and welded crank. Great shape. $120 Shipped.
