OKO Airbox Intro
Greetings:
Seeking ways to quiet Flash's lusty roar. OK, ear-piercing whine, but still... Too-loud early-morning take-offs not winning many friends among the Casa Wheelman neighbors. PG Short contributes the lion's share of the racket, but surely the intake side plays a role.
Enter VT Cycles' OKO airbox, affordably priced at VT, fits Elite (see below) and pretty much the Only Game In Town anymore for the Elites equipped with OKO CT manifold and carbs.

Re: OKO Airbox Intro

Sorry Dawgs! I got called away afore I could post up "Pics".
First, a minor Gkitch: there was a 3/8" hole in the back half of the box - the UNfiltered side - for reasons unknown.
No worries: a rubber plug from Wheelman's Vast Stash O' Trash happened to fit perfectl to close the hole and keep Flash from inhaling unsanctioned intake air.
Installation looked uncertain at first. The tube from the box to the carb bellmouth sets the box at an angle too steep to align the mounting hole with the AF16 mount point.
Fortunately, the tube is long and flexy enough to bend down and inward enough to clear the side skirt. No kinks. Not too much tension either.
The mount is via a spacer nut, a stud that engages a 10mm nut behind the hex cutout in the case., and a 10mm bolt through a mounting dowel in the box. Simple and clean.
The box definitely quieted the noise from the Port side. It also gives a certain "resonance" to the timbre of the intake noise, probably the result of the rubber trumpet-shaped tube en.
Definitive performance testing to follow.

Re: OKO Airbox Intro

Note that my box looks different from the pics on Vendor sites.
That's because I trimmed (hacked?) away a flap of plastic on the outer half whose purpose appeared to be to make the box look more "Stock-ish". It was blocking easy access to snug the clamp, so went bye-bye.
Another thing I did was to saturate the two layers - one fine and one coarse - of wafer-thin foam with K&N Filter Oil.
So much that it formed a red puddle on my Priceless Persian Rug that is Flash's bed in the boudoir. Kitty Litter saved the day.
FIRST RIDE: The jetting seemed the same, intentionally a bit rich for cool-running longevity. I like the tuned timbre of the intake howl better than the UNI that this box replaced.
More like a music note than the white noise of the UNI. Trolling around the Casa, I received 33.29%fewer dirty looks than usual, so maybe a bit quieter.
Same lusty lunge of acceleration when the TinyTach strikes 8K. Top Speed maybe next week.

Well if it ain't much quieter than with the UNI pod, it does feel a good bit faster. Riding up home on Deepinnaharta Freeway on President's day, unusually light traffic found me in the left lane and passing briskly-flowing traffic. Lots of Priceless Looks!
Alas, I had not Garmin-Girl in my Intake Air jacket, which will be remedied tonight. Alack, the traffic will be back to Slow Normal, too...

Re: OKO Airbox Intro
I was wondering why it looked a bit different. I see a few of these running around here.Wheelman-111 wrote:Greetings:

Have you heard of a kuka airbox? It's traingular in shape. It's what I was running before I change my setup. I kick myself for trading it. but I didn't think I'd needed it when I did that.
I tried a google search but couldn't find it. Anyone else have any experience with the kuka airbox?

Re: OKO Airbox Intro

Like the AF05 before it, exotic parts for the AF16 are becoming more scarce as the Aftermarket is realizing the sales volume don't justify production or even inventory costs. Sad, but true.
I think it's feeling faster because I was jetted so very rich on the UNI and this box has a much thinner sponge material, thus supplying less intake drag and leaning my mixture to closer to ideal. Temps haven't risen much, but the throttle response and top-end power seem stronger to my Butt Dyno. I'm about to head home. Full report to follow if'n I don't blow up.

Traffic, routes, and unfavorable winds have prevented me from finding open road with enough distance to stretch Flash's legs.
Good news: on a 1/8 mile stretch of on-ramp, Garmin-Girl recorded 63.4 MPH, which is 2 MPH faster than I've ever seen in that spot.
Bad news: Cruising back from State Inspection this afternoon, down overpass with a hard quartering tailwind 68.3 over about a 1/4-mile WOT run. Still climbing, but I'm losing heart/nerve holding it wide open when I gotta be someplace. Still, pretty comparable to all-time best of 69.9. I'm shooting for 72MPH on 72ccs. Without grenading.

Rheumy Wheel-eyes mostly riveted to the Ribbon O' Asphalt unrolling before me. However a quick glance at the CHT was reassuringly low at 300-ish. Yeah, I know it's rich... but too chicken to lean it much more - once bitten. Actually, twice.
