It has now been scientifically researched: No matter how open your exhausts are, motorists really don't hear you. The rest of the world does. And the rest are increasingly pissed off by that noise. Even me, as an old school biker, it annoys me. But there are people who are a bit hypersensitive to what we like without making a roaring noise.
This morning I walked to my moped with a fresh baguette, oranges and delicious cheese. A modern-looking mother stepped out of a better middle class with an exemplary stylized child of about two or three years old. Children do not have a license plate that can be used to estimate their age. That's a drawback. When that child saw my V-twin standing on the jiffy, she covered her ears with a scared face.
Her mother gave me a reproachful look and began to comfort the child. I stuck the baguette in the neck of my T-shirt, put the cheese in the suitcase. Put the vitamins on top. Put on my bot cap. Waved my leg over the buddy, turned on the ignition and started. The mother came up to me and asked me to turn off the engine until she and her daughter were out of the picture. Jacinte was highly sensitive and could not stand a lot of noise. The lady then reported that she was also highly sensitive. She wanted to tell a lot more about herself. I thought I could put my hands over my ears like her daughter, but realized the limitations of that approach. After all, I had my helmet on. Jacinte, meanwhile, wept convincingly. I tapped the box into one and rolled off the curb into freedom.
Sound that you keep hearing
In addition, I enjoyed the brave snort of the K&N filters, which have resulted in impressive fuel consumption on the 650 cc Guzzi with modified nozzle assignment. Also seems to have something to do with a series of Dell'Orto's that were once delivered with wrong throttles. That still needs to be investigated. Because a 650 cc Guzzi that runs 1 to 12 in a quiet dynamic driving style is actually great. On the other hand: after my first Ural combination was fitted with flowed heads, larger valves and other valve springs plus an extremely rare cross camshaft, that thing ran at 120 1 on 6,5. And that was also partly due to a set of thick Pacco – made in Mexico – competition carburetors.
But if you want to experience sound, a bunch of K&N's are much better and cheaper than noise pipes. Because above eighty you no longer hear the exhaust decibels themselves.
Yet those noisy pipes also had their charm
And the sound of classic single and two-cylinder sports lungs is much less of a nuisance than that of a four-cylinder extended to 12.500 rpm. Or a modern, fat V-twin. The unsurpassed Sander van Bergen once organized the Tunnelrun around Amsterdam. The two biggest celebrations were the noise measurement with the stuff of a police officer friend. With some fiddling with the ignition advance, Comrade Ernie's standard WLA hit 120 dB(A). And that's solid. The other highlight was a ride on the then newly redesigned Prinseneiland. The brave column of old stuff – recovery: classics – set off the car alarms of the lease bins and kumpannie cars parked everywhere.
But yes: that used to be….
