Notice it doesn't have one hole. It has a gillion holes…
Thank you for doing these videos Jay … I truly enjoy each and every one
Peace Kelly
Where is stuttering John
How about a turbo motorcycle Jay? Like the early 80's editions.
Seca turbo 650, KZ750 turbo, or the popular Honda variation.
Thanks for all your great work.
That wobble is very similar to what aviation engineers call Pilot Induced Oscillation (PIO). The brain the the mechanism fight with each other and attempt to continuously compensate. One needs to take one factor out of the equation for the system to stabilize. Early Space Shuttle fly-by-wire system was very prone to the condition. They actually built a time damper into it to avoid pilots getting into the oscillation.
Thanks for this.. always good car films, but this was really grand. And your guest was fun.. I love what he's done to his bike, suspension, brakes and all..
had I Vincent money.. I would do exactly the same. If only.. sob..
Excellent.
WF
I find this interesting even though I don't know much about the mechanical work of bikes and cars..I'd love to be a pro in that kind of stuff
Generally, errr, I'm all, errr, for spontaneity, but, errr, sometimes a rehearsal would help. Errr.
Im not going to ride pinion with this guy when he takes his hands off the handle bars
Dat speed wobble
😎😎😎
I had a bad speed wobble happen to me on my Honda. It was so violent that I though I was going down so I took my hands off the bars to get ready to bail and it straighten itself out. I then proceeded to ride home and change my underwear.
Taking your hands off the handle bars makes perfect sense. The reason for the wobble is not enough rake in the forks. When you take your hands off the handle bars, you are both decelerating and shifting your weight to the rear which corrects the wobble.
Not sure I'd advocate operating a motor vehicle under the influence…
WooHOO, Jay's got a Stinger. Let's have a show on that please.
I hate to sound stupid, but while I've heard motorcycle guys use the term "black shadow" before, I've never heard of Vincent motorcycles. Learned something new today.
Are new Vincent motorcycles available like the Indian?
Small aircraft such as Cessnas have the same vibration problem with the nosewheel. To counteract it they have a piston/oil 'shimmy damper'.
Nice bike. How much is it? Jay, you're doing an awesome job. I watch your videos continuously.
LOL Im not saying this doesn't work in principle it makes total sense but lets be honest… your lucky no matter what if you recover smoothly from some bad wobbles.
hey jay i think ud realy like the chevy venture awd model 2003 its real special i love it for life
I did the same thing one time leaving a party drinking too much, got on the bike , went into a speed wobble and fell over. Thank God the bike didn't start.
"Vincent suspension was so advanced" … (30 seconds later) "it was a very primitive design"
These two worked well together. Too bad Laney doesn't work on other things so he and Jay could do another show.
Sells one a month ………. It s interesting that all the mods seam to come from every nation other than the one that made it .
nice upgrades !
Hunter Thomson wrote about the Vincent. Frist time I'd ever heard of it.
Hi the bikes are great and by the way jay leno's garage rocks
Jay, could you do a show about the bike once owned by Elvis in which a representative of yours found apart in a garage in Wisconsin during a yard sale? … that you personally went to give an offer for the pile of parts… ?
does that strategy to take your hands off the handlebars work on sportbikes as well?
Woah that engine looks fantastic.
flying merkel was monoshock
Driving a lifted Jeep, I understand the phenomenon of "speed wobble", or "death wobble" as we call it, very well. Just letting go of the handle bars accomplishes two things. 1) You're not on the throttle any more and your speed will decease. 2) It's an ingrained nature to try to stabilize the handle bars from swaying back and forth. So you are actually helping the wobble continue by "pogoing" or "sawing" the handle bars back and forth. Basically, you're helping the problem instead of smoothing it out. It's pretty much a geometry, or worn/ loose part, flaw. But these are the things you deal with if you love your ride.
uh uh uh uh uh uh uh uh uh uh uh uh

I love this guy`s videos, I even forgive him for having one of every fucking thing!
The springs that the other guy said were softer, than the stock 200 pounders, looked much stiffer than the originals, the closer coiled a spring is, the softer it is.(metalurgy & guage being more or less equal)
Tank slappers are sometimes due to the forks being just a bit too long, shorter by just half an inch may cure it.( tricky with girders, easy with most telescopic forks)
And steering dampers are unnecessary mostly, if the geometry is right, the 2nd best thing I ever got rid of, after wife no 1
Another counter intuitive trick to scare the pants off you is counter steering, but that`s another story
That guy must've been stoned
Paul J, you are so right about 'counter steering', but way back (82?) when I first learned about it I was blown away and it saved my life many times over. It's just physics folks. I also loved the 'tank slapper' story. I was always told to twist the throttle. harder.
Claude Rains, you're also right on. You will always go where you're looking. When you see a newb run into a tree, you know he was looking at it.
I don't understand why people get so mad about people putting modern parts on old bikes. better they are kept running. They can always be put back later.
I'm guessing he's never heard of , Indian or BMW? Both produced with rear shocks from day one. How many 0s are in a gazillion?
Please watch Youtube vid of BBC's TOP GEAR's run through Scotland 1 in a steam engine Locomotive, 1 in a POS car and the little guy on the Vincent Black Shadow, 1/2 way through he's begging to die! when he got there, he walked like John Wayne on a good day!
what no ride?:)
The Vincent Owner's Club's 50 Year reunion was held here. Camped in the old territorial prison's main yard.
