I like how you said you were rebuilding this engine you called it an engine each time you referred to it I hear so many people call an engine a motor and an engine is internal combustion (gas) and a motor is electric!!! Good video you know what your talking about
I hate to kill your purist ideology but an internal combustion engine may be referred to as a motor. If the term "motors" were electric specific and "engines" were automobile specific then I wouldn't have the motor functions I need to run specific engines in trading card games. 1.machine or device that converts any form of energy into mechanical energy, or imparts motion.
My Cessna 182Q has an O-470-U/TS (opposed 470 cubic inch reciprocating 6 cylinder on 100 octane fuel) manufactured by Teledyne Continental Motors. Outboard boats have, outboard motors of the 2-stroke & 4-stroke flavors
I concur sir. So many people even mechanics do not know the difference as you can see by there reply's. However it looks like only three people still do not know the difference. Maybe this will help them understand. The word engine derives from Old French engin, from the Latin ingenium-the root of the word ingenious. Pre-industrial weapons of war, such as catapults, trebuchets and battering rams, were called siege engines, and knowledge of how to construct them was often treated as a military secret. The word gin, as in cotton gin, is short for engine. Most mechanical devices invented during the industrial revolution were described as engines-the steam engine being a notable example. However, the original steam engines, such as those by Thomas Savery, were not mechanical engines but pumps. In this manner, a fire engine in its original form was merely a water pump, with the engine being transported to the fire by horses.[3] In modern usage, the term engine typically describes devices, like steam engines and internal combustion engines, that burn or otherwise consume fuel to perform mechanical work by exerting a torque or linear force (usually in the form of thrust). Devices converting heat energy into motion are commonly referred to simply as engines.[4] Examples of engines which exert a torque include the familiar automobile gasoline and diesel engines, as well as turboshafts. Examples of engines which produce thrust include turbofans and rockets. When the internal combustion engine was invented, the term motor was initially used to distinguish it from the steam engine-which was in wide use at the time, powering locomotives and other vehicles such as steam rollers. The term motor derives from the Latin verb moto which means to set in motion, or maintain motion. Thus a motor is a device that imparts motion. Motor and engine are interchangeable in standard English.[5] In some engineering jargons, the two words have different meanings, in which engine is a device that burns or otherwise consumes fuel, changing its chemical composition, and a motor is a device driven by electricity, air, or hydraulic pressure, which does not change the chemical composition of its energy source.[6][7] However, rocketry uses the term rocket motor, even though they consume fuel. A heat engine may also serve as a prime mover-a component that transforms the flow or changes in pressure of a fluid into mechanical energy.[8] An automobile powered by an internal combustion engine may make use of various motors and pumps, but ultimately all such devices derive their power from the engine. Another way of looking at it is that a motor receives power from an external source, and then converts it into mechanical energy, while an engine creates power from pressure (derived directly from the explosive force of combustion or other chemical reaction, or secondarily from the action of some such force on other substances such as air, water, or steam
Very informative vidieo,ive learned alot from watching ur content,and how you give tech info is also great.most say just google it under manual specs.you are so much more thorough. Hey was just curious.i watched the 125 rebiuld all the way thru.is the reed valves replacing what normal hard overhead valves would be doing.because i didnt see a cam or chain going to valves.the only thing i see is reed valves n exhaust power valve.im new to this two stroke stuff!!snooky pa.just got a 94 jet ski recently.was looking at a 125 bike too.
Nice i have a 1997 c125 first aluminum frame gen.... and iam going for a total rebuilt, also a 1982 atc 250r going for frankenstien mode total restore !
Crazy. I made the mistake of kicking over a little polini 50 without the carburetor on and apparently there was enough fuel in there to start it and it shot a bunch of a fuel backwards out the Reed valve. Luckily did not catch fire
@@thooke222 Yes it was lucky. On my mates 250 with cracked reeds it backfired and sent flames into the airbox & that's why it set alight. when we was trying to bump start her she just kept spluttering & backfiring really loud. All the best. stay safe.
Hi, i have a old Stihl weed whacker "no Reed valves" and after replacing all the seals ect for the "vacuum" section, it still wont work right as skirt to bore clearance which is supposed to me Max .152 mm is more than that. So this loose fit not only dont provide enough suction build up but also the sliding skirt past the inlet port not seal well like a reed valve would and the port and pulse line be almost zero as it seems to be when i test it?
Cool Video, I bought some boyseen reeds. Do I leave the stock reed stops or should I install the small ones that the reeds come with? Thanks. Keep on making videos
I've searched high and low but everyone has a different saying on this.. maybe you know.. Is it possible to convert a Yamaha four stroke f9.9 into a 15hp by swapping the reed valve from a 15hp one? I heard it could be done, but I'm concerned about timing, air/fuel mixture not being the same with the new reed valve..
Subscribed! I have a 2 stroke scooter with stock parts. Nothing was changed. What will be the effect if I change the reeds from stock into carbon fiber, like a polini petal? Will it give a significant boost in power, acceleration, speed etc or am I better of with stock reeds? Thank you
Hey bud jus got this kart i no semi basics of engines..its f1 kart with 98 cr 125 2 stroke and was raced n dallas area where its huge in tx ..neways i got it of a trade and have a spare what he said was 97 cr125...i wanna do my first ever rebuild and thank i can do it..deff need some help.......id post pics but cant on here..
I agree with Zoopers. I 've wondered about them for a while. You didn't explain 2 stage reed valves, or am I giving away my age if they're not used anymore? Are all reed valve manufacturers accomplishing different flow parameters with " THEIR PROPRIETERY" materials and manufacturing? I like your articles and want to get another 2 stroke. I'm sure they have advanced a lot since the 70's. Oh no I told :)
I remember the 2 stage reed valve setup back in the day. I used to do some hill climbing et al back in the day with a Maico 501. That thing was a beast and you had to respect it or you would get hurt. I never got hurt. ;) I loved the 125 because you could jump and toss it around easier with some finesse. Always wanted to be a Trials rider too. Good times. :)
AAAAAA-HA!!!! ,,,,THAT'S WHY I EVENTUALLY NEEDED A NEW PISTON ASSEMBLY!!! ....I had changed my reed valves but was not thorough in cleaning the engine = the result of my negligence only cost me one or two hundred bucks ...BUT IT COULD HAVE BEEN MY LIFE!!!
Got a cr125 and the carb is dumping fuel from the overflow and running really rich. What could cause that? Already cleaned the inlet needle/float and the pilot jet. Any recommendations?
My yz125 idles but when I put it into gear I can ride it for 200ft before it’s sputter and stops, could the reed valves be the issue? I just did a carb rebuild and top end rebuild.
Is it normal for reeds just the reeds them self to be 44$ a piece I live in Canada New Brunswick and their 44$ a piece and I wanted to know if that was normal I'm doing some stuff on my 2005 cr85 like beakes new carberator stuff like new main and pilot jet new tire later down the road and I need a new reed and I asked someone who can order them for me and he said they where 44$ and I said are you sure they are I didn't want to believe him but later on that day I looked on Amazon and they where more then that again this is my first time really doing any updates to the bike so i wanted to know if this is mormal my dad knows alot about bikes but the last I'm he did anything to a 2 stroke was like 20 years a go when they where still 25 to 30$ so if you think this is a normal price plz tell me
@@adampaganelli4891 thx Adam for replaying and thx for letting me know that is the normal price for reeds keep up the good work the cr125 build is coming together very nicely
