Definition of Terms

[ken]

javascript:add("%20:-[")

As I have mentioned in previous posts, I was born with two left hands and am probably the most un-mechanical person one can imagine. Therefore I plead gross ignorance when it comes to a number of terms. For example, just this A.M. someone used the term "kurling" while addressing a handlebar issue post. I have no idea what in the hell a kurling is and I suspect I am no alone. Is there some sort of motorcycle term dictionary around or could someone make one? Another word was “nacille” or something like that…I kinda thing it refers to the instrument cluster but not sure. Can anyone slightly more intelligent that I help out here? Thanks.

The word is Knurling, ans that is the part on the handlebar that has the rough diamond cut areas where the bar is clamped to the bike. The nacelle is the trim pice around the speedometer.
Its just stuff you learn over time. Im sure a lot of it can be googled and searched out as well.

Wait a minute....I thought kurling was a form of that silly game you guys play up in Canada so you can drink beer and call it training, and so Canada can win a medal in the Olympics?

The nacelle is the cover for the speedometer.

Knurling is done to metal to make other metal 'wrapped' around hold better, or to make a 'grip' type surface, or just for show since you can make all kinds of different patterns. It is much much like roughening leather when glueing 2 pieces together. Sometime knurling is done to metal just for show but usually for a better grip or hold.

If pistons are slightly undersize you can expand the metal by kNurling. As has been stated knurling is often seen on chromed knobs, for a better grip. Knurling can be straight cuts, angel cuts, or cross hatched cuts, like checkering in wood, typical of older better made hunting guns.

Another place you might find this metal treatment is on antique telescopes at the eye piece.

Sometimes I will refer to the nacelle as a bezel. A sort of difference between the nacelle and a bezel is usually a bezel encloses a single gauge, but in this case so does the nacell.

I can't see much well these days since this monitor is on it last legs, but Cycle Cats pic where it says Ruby, if you ask me it shows 4 bezels, and one nacelle.

I was with Ken I didn't know what a nacelle was I knew what the folks on here were referring to but still didn't know what it was so I looked it up and found that it is most commonly used as airplane parts housing like the engine and also on wind turbines the word it self was derived from the Old French `nacele`, which means a small boat.
So I don't know how what I would call a bezel every got the name nacelle.

thanks to all for the advice, especially TC and the definition site. All helpful. Ken

@ oldbikers - thanks for the confession as well...made me feel a bit better. Ken

Ken,
In addition to all that, sometimes people use different words for the same thing. Some of it may be regional, or some what they grew up saying. For example (at the risk of sending the thread flying off into bunny trail space), the words used for carbonated drinks: some say "soda," some say "pop," and others "soft drink," and still others say . . . "coke." All talking about the same thing, but using similar, yet different words to do so.

The other day, Mac talked about "chassis grease." I worked in the shop with my grandpa and uncle through my late teen years, and I don't recall ever hearing that term. But, likely, what we used had a brand name or something that we went by. can be confusing.

From TC's link I was looking up nacelle just to see what it said, when I saw this definition:
Nomad - They are members of a motorcycle gang and will wear the club's colors. The bottom rocker will read "Nomad." In some clubs they are the enforcers. They do not belong to any one chapter. He will attend club meetings and pay required dues to different chapters, depending on his travels.

I'm not sure I'd trust anything else that site has to say.

Well, almost but it's 'curling'. ;)

[wheelie]

Petenomad, that Nomad definition is factual.

I feel smarter already guys. Thanks for the link TC. That can be very useful.

@ Petenomad - I agree that some of the information may be a bit off, but at least it is a source to use and for that I am grateful. Interestingly enough, the two words that I started this thread with are not a part of that site. Still, with all of the "grease monkeys" on this site, there is a world of information and experience. I learn quite a bit just by reading the posts, but there are some things I would NEVER attempt...too timid, insufficient tools, space and ....I have to help out the economy around me. Fortunately, here in Germany mechanics are required by law of have training and a certificate that they have completed that training. And the owner of the shop must have a "meister" certificate which means a greater education in a particular field. So I have trust in my local shop mechanic. In may ways, I really like the German educational system...certainly different from the US. But this is all way off thread so I will shut up. Ken
