I want to know how you even found those things. What exactly were you doing on the internet?

I’m guessing that ‘Juggs’ gave you the idea

.... the bike just ripped.... maybe the tubes "do do something" was my post pondering conclusion.

mine pulls the rig and the open plates definitely make a difference.

Good for you, you managed btw!

Okay, I've been meaning to ask about this. I've taken the engine plates off and ridden the bike that way for two weeks. Can't say it made a detectable difference, and made no difference to fuel stats. Also, when I have the bike parked in neutral and the engine revving there is only a very minor (tiny) air flow in through the cover holes shown in Lennstang's photos. My feeling is that air intake only really changes if you've changed over the air filter and removed the two black plastic snorkels. Any thoughts?

I've had a deep and meaning discussion with myself over a beer about this. My thoughts: 1. I like the idea of the honeycombed or louvered vented plates - very cool; and 2. it makes engineering sense, particularly if the rest of the restrictive intake hardware is out of the way.

So, due to an acute attack of FOMO over gucci engine plates, and pending the air filter mods, I've put a small nut and a washer as spacers behind the engine plate to give it a 5 mm standoff from the air intake cover, creating an air gap all round.

I'm now three weeks and three tank fills into the vented intake trial. I've convinced myself that there is in fact a very slight difference - acceleration from low revs is, maybe, fractionally better, and the acceleration curve is, again, a smidge smoother. On a scale of 1 to entirely subjective but nice if it works for you, I'd say its at the "nice if" end. Can't hurt though, and looks cool. So, here's my engine plates and what they look like on with the stand-off spacer nuts behind them.

I’ve done the spacer thing on both sides after refitting my custom name plate so it is all matching. As much as I liked the ‘drilled OEM plate’, my ocd won’t allow imbalance.
I’m riding it next week, so I’ll see if there’s a noticeable difference.
