Jeff at F.A.S.T. Racing ported(drag port) the stock cylinders I use on my stock stroke banshee.I also use 35 m.m. PWK's converted to alcohol.I've already run a 7.38.That was with traction problems.The first time I finally got it to hook up,I crashed it.Haven't raced it since but I do plan on hitting the dirt tracks soon.It pulls insanely hard.It should easily go high 6's.
Jeff is awesome.
Just making sure.A good helmet should be a no brainer and a chest protector would be a good idea.Leather jacket might also be a consideration.
Also,my friend michael has Jeff's dune port,cpi inframes,stock stroke,and stock carbs.
He has run 8.20's.With bigger carbs,I think he'll go high 7's.That's with Jeff's "dune/play" port.
