I spoke to Denny at Flowtek last month. He was very helpful with information, I am new to the Banshee world, I was all about the 4-pokers before I purchased my shee. I am tearing down my shee for a frame off restoration. Next week I will be sending my jugs, flywheel and head to Denny. Just based on information I read on here and everything2stroke, and speaking to Denny. The price I just cant beat.
