Stage 1 Porting - ZR-1 Net Registry Forums

Well, I am pressed for time so I can get the snake skinner project on the road sometime soon, so I am doing a "stage 1" Plenum port this time around.

Primary: 36mm for plenum narrowing to 35mm at the fuel injector boss, boss is removed and will taper to 33mm(maybe 34mm)

Secondary: open to 36mm to fuel inj boss. clean up after that(flap)

Going pretty fast, I did 5 IH hole down to the Inj boss in about 2hrs,

So we will see what we get
