Harley historians... May I pick your brains?

[sunhuntin]

my co worker [who is a complete plonker and thinks he knows everything when he knows jack schit] reckons it was a "peter davidson" who "invented" the harley thump. i can recall no peter davidson of the original founding fathers, and am almost certain that the harley thump has been around since the v-twin engine was first designed [1909?]

naturally, he refuses to listen or believe anything i say. i told him there was no peter in the founding four, so he changed his story so that peter was a recent addition to the factory, and was no relation to any of the founders.

anyone with decent facts to either back up or stomp down his theory will get bling, and the thread printed off and waved in his face.

btw, this "debate" started after i commented how nice a harley sounded as it left the forecourt. coworker reckons hes gonna get rich, buy a huge boat and a harley and ride it all over the little islands [ie, uninhabited!! no roads!]
hes a total bullshit artist, which is why i argued with him. he even trys to educate me on my favourite singer, who ive been listening to for a decade, and he has only just heard of him.

PLEASE AND THANKS, WITH A BLINGY ON TOP

Why are you arguing? The guy sounds ever so slightly developmentally challenged. He'd probably have a good argument in front of a mirror.

Completely confuse the guy and agree with everything. That'll piss him off . . . :yes:

thats a good point, lol. but if i just cave and let him think hes right once, he wont ever shut up.

he apparently has a brain injury, but like everything, im inclined to not listen. ive lived with a guy with a brain injury, and co worker is nothing like him. compared to glenn, co worker could be a genius.
you can never tell when what he says is shit or truth, so its all bull until proven otherwise

William Harley and Arthur Davidson founded the company, Walter and William Davidson came on board a bit later. Didn't see any peter Davidson in there

BTW this is interesting..1935 The Japanese motorcycle industry is founded as a result of Harley-Davidson licensing blueprints, tools, dies and machinery to the Sankyo Company of Japan. The result is the Rikuo motorcycle

that is interesting!
yeh... didnt think there was a peter in there anywhere. would it also be fair to assume that the thump appeared at the same time as the twin engine?

[98tls]

Have never heard one thump...........old singles thump........harleys potato.....

[crashe]

Sunhuntin - I have the book 'Concise history of Harley-Davidson' by Shaun Barrington.

So if there is any other things you want to know..... I can check out the book for the info for you.

I'm no expert but I've read (and have in my posession) plenty of good books on HD. They cover everything from the founding of the company, progress, business acumen or lack thereof, styling, family issues, hard times and into the good times. They cover singles, scooters, Panheads, V-Rods, Twin Cams and even the gang sector who appear to revere the brand but NOWHERE is there mention of a Peter Davidson, and I've read every book I have, cover to cover.

I may have missed something in the Knucklehead section tho'.

Actually there's three spuds; potato, potato, potato but only if you have the idle speed right. If it's too slow (and the oil circulation is minimised) it eventually goes 'potato, potato, pa-dump'.

Never let them idle too slow.

hey, yeh! that is the guy i work with! wow, hes done more than i realised!!

peasea... thats what i expected. ive got heaps of books as well, and have read most of whats written in them. aint no mention of a peter there, either. all i can think of, is hes thinking of willie g, but he aint the "inventor" of the harley purr either! hes a bike designer, not an engine builder!

Amen, to that

The machine recognised as the first true HD engine was built during 1902-03. Bore andstroke were 3x3.5 in for a displacement of 405cc. Courtesy of The Ultimate Harley-Davidson by Mac McDiarmid...again no mention of anyone called Peter

[Paul in NZ]

The distinctive 'sound' of a HD twin is simply a factor of its narrow angle V Twin with both rods sharing a single crank-pin. ie it's not magic or patentable becuse it is simple mechanics. Given equal capacity, dimensions and exhaust system an S&S engine will sound the same as a real HD engine..... Just like a Triumph Twin (360 deg crank) will sound different to a Honda Twin (180 degree)....

Your friend is a mouth breathing idiot and it alarms me that he would be allowed to fill a car with fuel or check my wifes oil... Lets hope he does not breed...

[ganit88]

nah hes wrong, the thump comes from the fireing order and the stroke as they fire 135 degrees apart. so hes a twat also peter davidson is in charge of product marketing in millwaukee.... ganit

[sunhuntin]

paul...too late! hes got 3 i know of, with the oldest recently appearing in court on theft charges. :shutup:

ganit... do you have a link to that info? any idea when he joined the company? :yes:

[peasea]

The crank rotates counterclockwise when viewed from the left side. While most engines have a crankpin for each piston, a Harley as only one crankpin, shared by both pistons. That means the pistons go up and down ALMOST together. Because of the V shape of the engine, one piston will run ahead of the other by the angle of the V, or 45 degrees. In this case, the rear one leads the front by 45 degrees of crankshaft rotation.


So here's the firing order.

Front Bang, rotate 315 degrees - Rear Bang, rotate 405 degrees - Front Bang, rotate 315 degrees, - Rear Bang, etc.

William S. Harley and brothers Arthur, William and Walter Davidson constructed an engine from scratch and redesigned the frame of the bicycle to make it stronger and more suitable for its new role in 1903. They produced 3 bikes in 1903 and 8 in 1904. 2003 was the 100th anniversay of the founding of Harley Davidson and they stated then that they were planning to produce 200,000 bikes per year from 2003. I don't know if they met that goal.
Next year the 105th anniversay will be celebrated.
HOG was established in 1983 - a factory sponsored club that now has over 400,000 members worldwide.

in fact it was a little earlier than this about 1928 or 29

[sunhuntin]

Is it the guy with the limp or the old timer with the grey beard?

neither. im sure vic would love to be called old timer to his face [actually, i call him old man all the time so.... lol.] vics an old school biker, but he dont ride cos he reckons hed end up divorced. lol. shoulda seen him droolin over an old trumpy that came in the other week, lol.

alan is the limpy guy, and there is no way he would dispute me when it comes to bikes... except to decline a trip as pillion, lol.

the plonker in question has since left *DOES CRAZY DANCE* so my stress levels have gone WAY done in the last few weeks.
