89mm BIG Bore 62T cylinder

[#ZERO]

can someone enlighten me on the fpp manifold deal?
he's talking jigs etc...i just don't see the need for all that but i might be missing something?

Apparently he needs a jig to convert the 61x FPP exhaust manifolds to the 62T bolt pattern and for port reshaping. :scratchchin:

the way i understand it is that they use a jig to port match and enlarge the manifold and headpipe.it has nothing to do with the bolt pattern

Yeah the bolt paterns on the 61x and 62t are the same, only difference is the 62t uses M10 1.25 bolts and the 61x uses M8 1.25
