    Great input. Thanks. Is coming along faster then I thought.

    The goal is to have the glossary written by the members so with suggestions please put definitions as well. That way it is a group effort and we can edit as needed, as we go along.

    To make it easy to find what different terms mean or the common name for parts and tools, I thought we could do a community written glossary.

    Will help new folks a great deal.

    I think it'd be a good idea to include the names of bike frame parts too, since we use them in reference to where things are mounted.
    Head tube
    Top tube
    Down tube
    Seat tube
    Chain stays
    Seat stays
    Bottom bracket
    Rear (and front) dropouts
    - other terms may come to mind soon.

    BGF,SBP. When I started here, I wondered what these letters should mean. There may be others.
    I use no abbreviations.

    True anecdote: When I was a kid, I should learn to play piano. That did not work somehow. More than one finger at the same time. So I learned typewriter. With the years it became a minimum of 250 characters per minute. So I do not use abbreviations.

    Yeppers Youko, we are getting there. I kinda messed up and figured out what I was doing wrong so will be a little neater soon. LOL, I hope.

    That was funny Paul.

    Amazing the way the mind works. I picked up the piano like it was nothing and still type with only 3 fingers of either hand.


    Just dawned on me. It was the acronyms that got me thinking about this years ago. A bunch of us were gonna do just this. I think we did 3 and sort of wondered away.

    I am almost embarrassed. Was 2 years ago. Well, that is several decades in internet time. http://motorbicycling.com/showthread.php?t=23277

    N- Nitrous kit- A bad idea, see also, darwin award, see also blown motor

    D- Darwin Award- An award given out to the individuals who removed them selves from the gene pool in a way that promotes survival of the fittest.

    B- Blown motor- A motor gone haywire, could be as simple as burnt rings or could be as bad as a motor reducing its self into its base elements around the proximity of your groin

    "WOT is Wide Open Throttle

    Gap: the distance between the electrode and ground on a spark plug, usually measured in hundredths of an inch.

    Torque, here usually in reference to head nuts: the measure of tightness, measured in inch pounds (for these tiny motors) or foot pounds. 12 inch pounds = 1 foot pound.

    Mix, referring to 2 cycle oil in fuel: 32:1 is 32 parts gasoline to one part oil, equivalent to four ounces of oil added to a gallon of gasoline.

    TDC: Top Dead Center, the position of the piston when it is at the very highest point in the cylinder. Usually used in relation to ignition timing, but the 2 strokes have non-adjustable timing.

    Four stroking: a 2 cycle is supposed to ignite on every piston up stroke. If the engine is too rich (too much fuel), it will fail to ignite one on stroke, then pre-ignite under compression on the following stroke, then not ignite, etc.

    Mag: Magneto, the coil of wire inside which the magnet rotor turns, generating electricity.

    Porting: the practice of carefully grinding the intake and exhaust ports and the intake pipe and exhaust header, so that the edges match. This makes for better flow, and thus more power."

    ^Nougat

    " 'porting' is grinding the ports bigger, while "port matching" is grinding the ports to match."

    I don't plan on being a whiny FNG. If after much patience and trial and error, I'm unable to get the cheap motor up and spinning, I've already resolved to spending the pretty penny.

    Norm's section has most answers if you dig. These things are pretty simple devices once you read the troubleshooting steps. There is also a search tool at the top of the page when you go into any section of this site that is most usefull.
