Right, anyone who thinks a sprocket is going to make any difference on cranking doesn't have all of his marbles, plus he thinks the sprocket maybe 1/2# has a flywheel effect. Maybe if it was a flywheel off a D John Deere that weighs 300# it might have a flywheel effect. This boy has a lot to learn about physics . Steve
actually if you look at the physics of a flywheel you will find that diameter impacts torque more than weight but with that said weight still has impact . The ratio of the crank and piston weight of the John Deere d may in relationship to the flyweel weight of the d could be a identical ratio of the 11 pin sprockets mass to the 660 crank and piston mass .If the ratio same then both are impacted the same. Alot of internet experts on any forums including this one. Wither we agree something like the sprocket is impacting the clutchs frictional point of lockup or not once the clutch is fully locked the weight of the sprocket is part of the total rotational mass
 
I don't guess that 7910 dude cut the tapper for the tiny dinky sprockets out of the bar to use the big boy sprockets

You are speaking in terms of a running engine.

You are certifiable! Haha.
If you could make a bigger and lighter , flywheel then what would you say? Nevermind! Lol
You are extending the weigh further from the axis. F=M x A
Force = mass times acceleration.

A bigger diameter lighter flywheel is better however sometimes there is constraints like bell housings on automobiles and side covers on saws . But remember the old stationary engines had the large diameter flywheels with spoked centers to remove mass and still have diameter. Drag racers run into the other quiet often . They gear the car and shock the tall slicks then there top speed is limited before they reach the end of the time track so they either roll it out of gear or blow . So then they go back and change to a taller gear so they can pull the entire track but then the engine stalls leaving the line where the big slicks and pimp juice aids in traction so then they change the fly wheel to a heavier one and then they have it dialed in to run the entire distance and not stall leaving

I thought you were nuts for a while but now you are making sense.
*looks left...looks right* aaaaahhhaaahhaa

No weigh is not the same as mass


The angle of the dangle is equal to the mass of the azz providing the heat of the meat is constant.

Next question please.



once the clutch is fully locked the weight of the sprocket is part of the total rotational mass
Oh I think we've had this one

Sure, but it's close to its axis
Count the sprocket and flywheel as one and work out the Newtons × m/s2 difference one being with the stock sprocket and convince me?

Next question please.
 
Hey, i've got an idea, have your buddy in the video's take the bar and chain off, he switches between all 3 sprockets and after starting with all three sprockets, you pick which one was the easiest to start. Then repeat the same test again with the chain brake on. Would answer the perceived easier starting. I think it's a placebo effect, it starts harder, because you know it has the bigger sprocket.

Picture the Dos Equis Most interesting Man " I don't always act like a sixth grader when people poke holes in my theories, but when i do i make fun of their drive sprockets"
 
We have went back and forth with sprockets . Sprocket change is no harder to do than change bar lengths and we do that quiet often .

Did you just prove a point? Our point? The mass becomes more harm than good when close to the axis and is better served distributing the mass to the outside. Yes they thin them out and have holes in them. Seriously though , sure you will have a small gain in inertia but have 39% more energy per revolution from an opposite body. A huge overall 'loss in torque'.


What I say in linear mechanics in layman's terms is 'extended weight' is really a distribution of mass.
Distance of mass from the axis make acceleration and momentum or in rotational mechanics it would be inertia
Its all still relates to Newtons 2nd law of motion of lineal mechanics
(Force into mass × acceleration)
Force (weight) is now Torque and
Mass just becomes rotational inertia. area (r2)
 
Is there any chance this thread has gone onto never never land. The sprocket has not anything to do with starting and the inertia is effected very very little by the sprocket. Flywheel inertia is easy to change if some one really wants to. A small lathe can easily set a weight or reduce weight if needed. The one thing I really do not like about the 660 is the chain speed. It is just plain too fast. To put a larger sprocket to make the chain speed even faster is really crazy and non productive. Something that has occurred to me was to try to put as small a sprocket as possible to make the chain slow enough to run a 404. My saws that run 404 get twice as much work done as a 660. At least every hour I have to stop and sharpen the 660. The others will some times go all day. Thanks

Which brings me to my next point.


Kids! Don't do drugs.
 
If I was going to run a 404 chain and 25 inch bar as I've done already I would run a 8 pin sprocket on my 660 the seven pin sprocket just doesn't cut it for me so I have a 404 7 pin sprocket forsale if anyone's interested. A 3/8- 8 and a 404 -7 diameter is very close giving you basically the same gearing .FYI for all you internet experts that hadn't given it any thought or knew about sprockets and gearing changes
