So I crashed over the weekend and tore up my throttle cables on my 19 WE. So I took it apart to put new cables on it and for shits and giggles I popped off the throttle body to check out what the “hand polished head” looks like. Well idk about u guys but this looks like a stock head to me. There’s still casting marks on the side that even I could take out in 5 min. Idk just seems like a sales gimmick to me. If anyone has pics of a stock 19 head for comparison I’d love to see them. Photo

They probably take measurements from a 'hand ported' head, then use that as the casting base for the WE?

hand polished ? wow ..i quess Honda has redefined the word polished

the funniest thing about this particular signature is that by the time you realise it doesn't say anything it's to late to stop reading it

You don't polish the intake side. You polish the exhaust side.

The intake is left slightly rough to mix the air and fuel better. Exhaust side is polished to flow better.

That is my understanding: even atomization (hopefully aided by port turbulence) on intake side. Maximum flow on exhaust side.

According to MXA, the difference between the WE and standard edition is "mild milling of the valve pockets (it is neither porting nor polishing)"

That was going to be my explanation...

That would require a complete new head casting just for the WE. Kinda seems unlikely to me

The casting mold would probably be way to expensive to have a specific mold JUST for a WE low volume bike.

I agree there. Mold cost are no joke.
But 1 mold investment vs labor $, employee $, QC $, ect on if its really manually 'hand ported'. Tough one to which is cheaper.

Marketing Dept. strikes again. Still, being able to look straight into that downdraft intake and see the back side of the valves goes a long way to explaining the HP those things produce. The only problem was making it fit in the chassis.

It's pure "marketing wank". That's an as-cast cylinder head with minimal machining at the valve seat as stated by someone above with the MXA link. Sometimes a valve job does improve flow, sometimes it doesn't... Depends on how optimized it was in stock trim.

The graphics, suspension and higher resale value might be worth the extra cost, depending on how you look at it.

I don’t think you would want a hand ported head mass produced. It could actually be lower horsepower if the guy was having a bad day.

|

8/20/2019 7:43 PM

The works edition is stated to have less hp than the stocker...

when in doubt, pin it out

To be fair on Honda's site it says "Hand Ported" not polished, only a few mags say polished (for some reason, MXA and Dirt Bike being a couple I quickly looked at), so those who are disappointed that they are not polished should now not be.

As for "Hand Ported" it can be argued forever and a day what that entails, it could be reshaping ports or milling of the valve pockets, etc. Either way it is different than stock.

You can make every excuse you want for them but if that was my bike I just dropped 10k on I'd be pissed as hell. When I bought a GYTR head for my yamaha I expected a CNC ported head, and that's exactly what I got. There was no play on words bullshit, they know exactly what people expect when they hear "ported head" and that's not what's in those pictures, at the very least there should be no casting flaws present. If they're really trying to pan off a little bit of machining near the valve guides as a "hand ported head" that's just asinine, if anyone got a head like that back from an engine tuner they be pissed and rightfully so.
