Factory B Pipe- Wammer Mod/Port Match and Dual Cool

[Mike W]

so,

bore the manifold to 48mm
bore the headpipe to 48mm

drill and tap the mani for dual cooling....

is there more to it?? any stinger mods?



I know Team scream mods the stinger as well.....and dont most Bpipes come bored at 46mm nowadays anyhow?

I know the old school designs were only open to about 42mm...


if you have an angle grinder and compressor with a rasp it'd take about an hour to do the boring on both pieces...

I measured mine yesterday and both are ~50mm. I guess Chuck opens them up a little more than 48mm.
