i wouldnt doubt it for a second, he knows his shiit. from talking to him a little on here and seeing what he says, he seems like the man to go to with your engine if you want it done right

AHPminis · 05-29-2008, 08:32 PM

Or you can ship it to me and I can hand it to Eyvind Boyesen and he can charge you $350 an hour for his time... and then you guys can bitch about that being too much and AHP being too cheap because I know giving you guys a good deal leads to bitching

The first response in this thread to the guys question was a perfect explanation for someone who just wanted to learn what porting means.

DC50 · 05-29-2008, 10:37 PM

I would rather pay 350 and get the thing ported then pay 100 and just have it cleaned up. But then again thats just me.

My new head is done by DOOD

RLucky82 · 05-29-2008, 10:43 PM

I seen HACKMUNCH do some great porting work to. He has done mine and Sam, Brent and Jays Vegas bikes!

DC50 · 05-30-2008, 07:08 AM

actually i'm 23, not sre why that really matters. I'm bashing anybody, just saying I would rather pay more to get more done. Didnt say who was doing the two port jobs!

Pretty easy to see what's going on...

75% of the potential gains in a port job are achieved with 20% of the work involved in getting the remaining 25%. There is a bit of "get what'cha pay for" involved.

But...$350 is flat-out robbery for a 2v single head, regardless of the guy on the end of the grinder, unless seat changes and welding/filling is involved.

Time is time. The cost for somebody per hour to do it is set in most places. I won't port for less than $100 an hour. The difference in the size of head comes with the time involved in doing it. It will take roughly 40 hours to do a 450 4 valve head correctly (including filling in where needed, porting out where needed, hand doing a radius seat, etc).

A little head such as these take much much less time therefore less cost merely from the time involved. When you pay someone to port your head you are not paying for the port, you are paying for the knowledge the guy has that is doing the porting.

National level 450 heads sell for around 3500-4500 depending on who is doing the work if that tells you anything.

Minibikes are pennies and don't have a "national" caliber hence why I still call them a hobby no matter how serious others take it.

The car world is different because every "performance" shop from coast to coast "ports" car heads and just the shear volume of buyers.
More buyers = cheaper price.

Sorry to jack the thread... anyway... Porting is changing the shape, location, size, etc of the port to increase potential flow and velocity through the cylinder head. You can tailer the ports to the rpm, carb, cam, exhaust, etc that you are running. The ultimate goal is to build a happy engine. Going the biggest and the best only makes for an expensive engine. Porting is another way to designate the characteristics of the head whether you want low or high rpm power. Porting will move peak power and torque horizontal and vertical on the rpm scale so care needs to be taken when doing it.

cleaning up is not porting.

Maybe this is what the kid wants:

A motor is no more than a compressor air in and air out making the air flow through the intake valve ignight and blow it out the exhaust valve. So what porting does is clean all the burs and inperfections for an example its like putting your fingers on your lips and blowing through them the air wont come flow out your mouth. But if you remove your fingers the air flows throught.

I don't wanna get in the middle of any debates of who's porting is the best or the best engine builder between this guy and the next.
I just do what I do and let the work speak for itself.
Don, Mark, Jordan, and many others have built and will continue to build kick*ss engines.
We don't need to battle like some companies do for there are enough people in this world to keep everyone busy. period.

Yea I like what you said there, coming from a business perspective. I am always trying to learn more myself all the time and yes I make mistakes here and there but I'm obsessed with my business and trying to make guys happy and not hate me. I put a lot of effort into each section of what the business consists of as much as I possibly can which at some point will probably drive me insane... at least were all young enough to be the old wise dudes in 20 more years saying "I've been doing this for 25 years son" but I'm not at that point yet myself but hope to be someday.

Yes, I found those while surfing the web one day, the owner reported much better throttle response and top end power. I wonder what he would say if he actually had some good work done?

That intake looks like they did it with a chisel.
