    Base heads, or zombies with £5000 worth of mega watt audio in their cars, from now on i am going to carry a spud with me, and it is going right up the next ones exhaust, and i am not joking, they are talking about them on the radio now but they are only going half way in describing how annoying these base heads are.

    :rofl:

    I'm not sure which is worse around here, the thumpers, the kids driving pick-up trucks with noisy mufflers, or the motorcycles (talk about vehicles I want to put a potato in the exhaust of...the new neighbor either owns a motorcycle, or has a friend with a motorcycle, and leaves it idling out in the driveway at about 7:30 in the morning...it's disturbing with the window shut, and even worse with the window open...makes me want to push it down the mountain so I can sleep past 7:30!) Why does anyone need to leave a motorcycle idling in the driveway? :grumpy: Now I know why there are townhouse complexes that prohibit motorcycles.

    Yeah, I noticed that motorcycles pass all noise bylaws. It makes no sense. In Old Quebec City, scooters are now banned because of the noise. If you ever heard a scooter, you'll realize that it's not very loud at all. Cars are louder, nevermind motorcylces!

    Bad motorcyclist waking MoonB up, I would push mine away from MoonBs house before i started it, i would not want to end up in some chemical mix on a lab shelf.

    Put it up the driver's exhaust, not the car's. It'll have more impact. :devil:

    Now stop hijacking the thread, there is a world of difference between a sweet sounding motorcycle and ground pounders.

    Not at 7:30 in the morning there isn't. :grumpy:

    It's one of those frustrating things...just when the weather gets nice enough for me to open the windows for some fresh air, the weather also gets nice enough for all the motorcyclists to start going on their joyrides. The planes heading in to land at our local airport are quieter than the motorcycles (well, except the one landing two nights ago...it sounded like a helicopter choking on a motorcycle...I'm guessing that one needed some engine repairs).

    Ground pounders are cool because you can blast them in the drive-thru of a restaurant. I'm sure they'll have a blast making a sandwich when the building is shaking!

    I think Moonbear is talking about those supped up Harleys that sound like a loud flatulating explosion :yuck: My brother-in-laws BMW bikes sound smooth and aren't that loud. To their credit the Harleys aren't that loud either unless you put a non stock exhaust on them. I have jackasses like that going up the street at 10:30 at night and early in the morning that think 900 dB of blap,blap,blap is something everyone wants to hear.
    Same thing with these base heads. 11:15 at night from 3 blocks away I can hear these cars coming with my windows closed. By the time they get near my house the whole place is vibrating and I s*#@ you not pictures and Knick-knacks on the wall are vibrating and tinkling. God I hate those people, no damned respect for anyone around them....
    I'd like to take a potato and plant it right upside their mush!

    I think it's worse where I am. I live off a winding country road that is close enough to town that it seems to be a favorite of the motorcyclists...and the joyriding thumping kids too. There are nights when I just WISH the price of gas would go up to $10/gallon so they would limit their time on the road to just getting back and forth to work.

    Yeah, not ALL motorcycles have to be that loud...one of the other neighbors has motorcycles and I hardly even notice them coming and going...but it seems most around here make them extra loud on purpose (probably doesn't help that there's a Harley shop in town either).

    At least with the motorcycles, I understand the need to be a bit loud...otherwise they'd get run off the road by the SUVs who can't see them (you just have to hope they hear them). But with those thumping cars...grrrr! I can't wait until they've all ruptured their eardrums and gone deaf (then I want to play some super-high-pitch annoying tone that only their hearing aids pick up :devil:).

    I have a Harley with an aftermarket exhaust system, but it's baffled to the point where it's hardly any louder than a stock exhaust unless you really crank on it. There are people with pickup trucks on this road that are louder than my bike.

    When we lived in our previous house, there was a young lady living down the street that attracted those idiots with the $2000 cars with $4000 stereos in them with subwoofers that would shake the windows. It seems like they only played "music" that was percussion and bass - I was glad when she graduated and left her parents' place. You could hear those idiots coming over 3 blocks away. As a musician, I treasure my hearing (and can hear that annoying "mosquito" ring-tone at age 56!) and I had to shake my head every time one of these idiots rolled into the neighborhood.

    Because you need to let the fluids in the motorcycle warm up to temperature before you go driving off, the same goes for your car.

    Its loud because it needs to be. Cars can hear it and know its there. The horn on a bike is a joke.

    The reason for the warm-up is a bit more complicated than that, at least for Harleys. The aluminum jugs are quite long and they expand quite a bit during warm-up. Until they are warm enough to not be able to comfortably touch them, it's a good idea not to drive off. If you start up a Harley (especially one with an older Evo engine) and just take off (especially if you're getting on the throttle) you are at risk of blowing out the bottom end (jug-to-block) gaskets or head gaskets. They are cheap parts, but paying some H-D mechanic $80/hr to tear the machine down to replace them runs into some real serious money. Allowing the jugs to heat up physically compresses the gaskets and reduces the chance of blowing them - especially important in cool/cold weather.

    I have an idiot kid a couple of houses away who has a rice rocket and when he starts it, he revs the hell out of it to make lots of noise before he takes off at high speed. His mechanical aptitude is about zero. Apparently he is unaware of the inconvenient little fact that when you start an engine with such tight tolerances, you should wait until the engine can build oil pressure and lubricate the valve train and other sensitive spots before flogging it.

    One has to love them Hardly Davidsons, their engines must grow by 1/2 inch when warmed up, with jugs that big it is a wonder their bottoms do not blow more often.
    My little velo can be noisy if i give her some stick, i imagine MoonB would get quite irate if i went through the box while passing her mansion.

    Yeah, the Evo engines (1340 cc) have the same bore and stroke as a Chevy 327 V8, and the Twin-Cams are even larger. All that aluminum has to stretch when it gets hot. The oil gets to the valve train and pumps up the hydraulic lifters shortly after start-up, but you should let the jugs heat up before driving off, and that takes a bit of time.

    I hate the "ground pounders" to. Usually a honda civic with a coffee can sized exhaust and a stereo worth 3x more than the pos car its been put in. Oh and usually a spoiler that is ridiculously large to. Wouldn't be so bad if they would drive by and then leave but because they have little else better to do they just spend a few hours circling the block :P

    I have to laugh at the bike thing though. I am a Harley fan so I am more than happy to listen to them go by but I find that the people that do the most complaining about those noisy darn bikes are the ones out there mowing their lawn at 6 am and running their weedwackers, chainsaws, and whatnot all day.
