Good point, TCO
My Dad would take a tiny drill bit and make tiny craters in strategic areas to further aid and got great results.
This was for a rail not a quad
Biger is okay. Smooth isn't.
You guys are right about fuel atomization, but bigger isnt always better.

I have tried to find ways for those of us without any testing equipment (dyno, flow bench etc) to be able to better understand how too much flow negatively effects velocity and can actually reduce performance and even efficiency, but so far it seems that were stuck with the same process that most all the builders have used.

Thats pretty much a problem since most have wasted many heads and spent unmeasureable hours testing the results, and thats not sounding like a good way to save any $$$ over the professional porting job.

Thats why I suggested questioning many people who do this stuff everyday since if you ask enough questions to enough people you may actually get a couple of them to offer some adivce on the "tricks" for the engine your working on.

Knowing which hump to remove more of, or what has been found to be the better corners to leave alone or rough to aid atomization on your particular engine is worth more than any clean up job is in hp. I cant remember how many times I tried to get info on the EX engine but I do remember only 2 or 3 people offering any real info, but that info was worth the efforts and one bit of advice saved me trouble too.

Sorry I dont know anything specific on the Bomb but if I had one I would make sure I was able to gain some knowledge on those little "tricks" so I would be more confident of what I was doing.

Call around, send emials as it cant hurt, but remember to share the wealth so others can benefit from it too.

I did my own port job on the intake. Not hard with the right tools.

You need a ball style allen wrench. I didn't the first time, and i don't know how i managed to, but I did. Trust me it's a big help.
