I loved the way my VFR 750 Sport bike's sounded........Most of the Ducati's sound this way as well.

Have you ever wondered why some types of engines sound "good" or more pleasing to the ear than others? Not just the Hertz of the sound but the spacing of the firing pulses. Most American V-8's sound good they have a pleasing sound, same with Harley v-twins...Most Jap cars with fart cans are just loud... I thought that you may find this interesting, especially Gabor and Jake. This uses the honda VFR as an example.. |

. Interesting explanation Ellwood .... of course I had to find a video of the actual motorcycle and hear it .... cool !!! Ray .... I like the Ford Flatheads too , and they were the only V8 I could get to run so smooth I could stand a nickle on edge on the breather and it wouldnt fall over ... it was a 1949 with the distributor on the front of the crank .... it was in a 6wheel drive truck that I used for hunting and drinking haaaa. Flatheads Forever !!!! |

The sound of my beloved Subaru boxers (and VW's) is caused by the unequal pipe lengths from the primary manifold pipes to the collector.... so the 2 pipes on the right side go down and straight back to the cat... the pipes on the left come down from the head, back 10"... then across 14" and into the cat....You prolly all know the Subaru sound, but the killingback imp has 4 equal pipe headers so it doesnt sound like a Subaru... it just sounds like any 4 cylinder (all be it, a fast one)     |

. More exhaust music stories .... a V8 by design has its own exhaust notes along the lines of a Harley V2 X 4 because of the necessary crank design ...... a 6 cylinder inline is considered a self balanced engine because always a pair of pistons going up and down in harmony to counteract each other and the firing order is precisely 120 degrees apart ... something like that anyway ... and an inline 6 with equal length tuned headers has a nice exhaust note .... ... but best of all is an inline 8 cylinder .... wish I had recorded it .... 1949 Packard 356 cu in straight 8 with a 3 speed standard transmission ... a real highway car ... bought it for $1,800 drove it 8,000 miles and sold it for $4,300 . Only repair was a fuel pump , could not get a new one so I bought a 6 volt positive ground electric that cost almost $200 at the time. That straight 8 was theeeeee smoothest running engine I have ever seen This picture is not my actual car but mine was exactly like it except not quite so perfect .... it looked like a pregnant elephant .... if farmer jim sees it he will want one. Look at the length of the hood .... the engine filled up the whole space .... looked like an engine out of a big old farm tractor . |

Did he ever race at Winnipeg Speedway ??? ... midget racing (dirt track) every Sunday evening back then . Most cars were out of town and some from California who did the racing circuit all over North America Some real crowd pleasers , usually from California ..... coming out of the 4th corner they would sometimes do a 6" wheelie as they headed down the straightaway. Not much racing around here any more. |

Harleys sound like Harleys because they are basically like 2 cylinders from a radial engine... as aposed to a V twin with both rods each attaching to the same pin... the Harley has a master rod attached to the one pin and an articulated rod attached to the master rod.... they both take up the same 'footprint' of one lone rod..... unlike a Japanese V twin with the cylinders offset slightly for 2 rods connecting to one wide pin, side by side... that is why the bottom of the Harley cylinder is so narrow compared to a V twin with 2 complete rods...

Yep a Harley is just a radial engine with all but two cylinders removed...That is why I used to run Areoshell 100 in mine, it hated synthetic oil, it just burned it, Aeroshell, no smoke ran great. Mine was a 1973 ironhead, cast iron cylinders and heads, had to do the valves every 15,000 miles, or about every 2 years. They have very long rods also that have some very extreme angles, The Japs had to really take some steps down in technology to try to get the harley sound.. |
