Damn, you guys are killin each other in here.............There are many ways to port cylinder heads......How ever you you get from point a to b is up to you.......
im not picking on anybody here, but I think you guys are starting to split atoms over this.....
Can you measure the difference between castings, yep, can you take out a .00000000001.....yep...
In the real world, what the hell is it going to do for a guy with an average motor, even a race motor.....
It is nice to have the equipment to do it, and it will come out to have balanced ports,symmetrical, and even port volume....we know it takes alot of patience to port a head, and thats is where the good guys are separated from the bad ones....
There is no way you can port a head in one day I dont care who you are, if you do than it really isnt ported well...unless it is a fluff and buff......
What alot of shops wont tell you is the truth about porting because every shop has to look better than the next one..
How can i make my shit look better than his, its all marketing.....remember the pet rock!!!
There are good motors and there are duds, what makes one better than the next? We all look at the head because it is the most important part of the combination. You can have 2 identical engines, run the same tune up, same rider, and have 2 totally different results, why? becasue there is alot more to a package than the head, you can have your rear tire misaligned and scrub off 1 mph, and that would make one motor better than the other one...All im saying is that results will vary from jsut a head, 1 job someone did for a customer he ran great, the same set up ran like shit another customer, and he says bad shit about him, and its the owners fault because his stupid,cheap, lazy ass cant put a chain on his bike..you guys know what im getting at because you have had these guys in your shop......
Like I said, i am not pointing fingers at any of the guys here, just putting my change into the conversation, we all need to make a living, but the greed tends to get to us and make us do less than a perfect job.....
When it comes down to it, its the damn governments fault!!!!!!
if it wasnt so expensive to live guys wouldnt have to rush out jobs to pay their rent!!!!!!!
