Mystery Scooter Theater 2010 - Case of the Fatal Left Turn

[Rianna]

I think this article is saying that if you have a pinhole in it then it's no longer any good? I can't imagine what this shrunken one looks like in it's present condition, but I wonder, after all it's been through, if it will last long if it is successfully expanded or rehydrated. Maybe someone else can translate this motorcycle speak article about rerubbering into a viable solution for a scooter carb diaphragm or seal if this B-Nitrile stuff can be ordered somewheres...

...nnno...that's a diaphram...

..my mystery is about the bowl's seal...

..reckon i should post a pic...

[Rianna]

Sorry, I've never seen it before. The material may be the same, not sure, but a pic would be nice...

Might be specific information out there somewhere about how to renew it, if I could figure out the type of material it's made of.

Now let me ask you, "Why did the motorcyclist hit our left-front bumper instead of the passenger side of our car?"


Rider errors killed this motorcyclist.

A sad story, but one we can all learn from.

Now let me ask you, "Why did the motorcyclist hit our left-front bumper instead of the passenger side of our car?"

Again, you know the answer to that question. New riders who have not, through practice, internalized the concept of counter-steering and use it instinctively, tend to NOT use it during a crisis. No rational thinking person would turn their motorcycles toward the front of a left-turning vehicle as in this scenario because that would result in hitting the vehicle at its front, AND being run over by the vehicle after the collision. They would, if possible, turn toward the rear of the left-turner.

But new, inexperienced, riders - having forgotten everything they ever 'knew' or had heard about counter-steering, would try to turn their handlebars to the left and find that the bike 'fights them' - simply will not go to the left. In fact, the harder they try, the more the bike turns to the right. The result, a collision with the front of our green car instead of merely a close call.

Oh, it doesn't really matter whether or not our car is green. Just as it is incorrect to assume that 'green' is the 'bad guy', so, too, is it incorrect to assume that the left-turner is at fault.

Rider errors killed this motorcyclist.

I'm sorry but I don't understand your statement above... the motorcycle was hit while driving the speed limit in his lane by a car that was turning left, and it's the riders fault???

The rider was in the blind spot, or no zone of the car in front of him, something riders need to be aware of, especially with bigger cars/SUVs. I posted graphics with the post that illustrated what happened, but oddly you can't see them unless you are logged onto the site.

Rianna, o~rings are made of various substances, one of them being Viton, I don't know if that helps.

...okay, i default on this mystery...

..it was a lame mystery to post here anyway...

..reckon imma have to contact Keihin...

 

..ssso...

..I NOW PROCLAIM THIS THREAD OPEN TO THE FIRST PERSON WHO SO DESIRES TO POST A NEW MYSTERY!!!

..that is, if scooterwolf says it's okay to do so..

 

[sidthesloth]

What shape is the seal? Can you cut it to size?

[wordslinger]

..it's black, probably buna not viton..felt like a 90 durometer..

..it fits the groove around the bowl..

..i left the seal at work today..but this is a pic of the bowl..

..the cross-section of the seal would be round..o-ring like..


  

[Rianna]

So it sits in that little groove around the outside edge, not down in the bowl?

Do you have a part # or information about the Carb so the type of material can be identified?

Still thinking it may not be an unsolvable mystery.

[wordslinger]

..yeah, i can...

..itsa CVK 20mm gy6 carb..

..serial #090610A

[sidthesloth]

Hmm, no trimming that baby.
