This may be a silly question but is it important how much metal you remove? Has each port to have the same amount of material removed and in the same place? If so how the hell do you do that and measure to ensure?
it's not as much as you would think. First you need to calculate your surface area at the valves and at the beginning of your header. The key is a smooth transition between these 2 points. If you use stock valves the amount of alu to remove wont be more than just the casting lines and the ridges where they bore in the head for the valveseats. If you "tuned" 1 runner I make cardboard templates to replicate the 3 other runners. If you think you are finnished you measure the volume of the 4 runners and hope it good. This is how I learnt it from books but practice makes perfect.
I'm back at it! Aint that cancer thing a bitch? I made a commitment to drive this thing the first MC meeting in February and I plan on using the R750 engine from my gsxf (100whp) Got the callipers I wanted
Hi guys, I don't have a big budget so I had to chose between fcr's and a big-bore so you all know I'm now accepting donations for a big block
actually thinking about changing those rear-sets, I really like those tarozzi's I have on my GT500 but that's not really something for a racebike. Got some parts back from the cnc guy today now find someone to weld it but with all this holiday shenanigans...
It's the bottom mount for the suspension link, there are some M8 treads in the frame so I plan on bolting these down before welding. Did I mention I was building all the cnc parts double
