One ring vs two

My brother and I used to start a moped backwards and try not to dump it riding in reverse.[emoji33]

Ugly chicks are just like mopeds..fun to ride..until your buddies catch you!! .

So what would be a better piston option if the Pistons had same skirt length and crown height? The heavier single ring of the lighter two ring

Lighten up the single

Lighten up the single

Then you end up with less velocity. Right?

 

[Deets066]

Wouldn't a heavier piston carry more torque? Like a heavy flywheel

The lighter one would rev quicker and have less stress on the bottom end.

That's s good question, I've really wanted to play around with flywheel weight.

 

[czar800]

I personally Think a heavy piston would just apply more stress. I don't think that it would carry more torque.

 

[Deets066]

If the piston is heavier it must have more mass, I would take the added stress if it gave me a little bump in velocity

 

[czar800]

Think of a flywheel it's storing energy, it's always rotating where a piston stops how many times per second.

 

[jmssaws]

It depends on what your doing with the saw, I lightened the flywheel on my 064 and I'm using a 034 clutch.

It's very snappy and I noticed no loss in tourqe.

How are we changing velocity with the weight of a piston?

 

[Deets066]

If made from the same material, it must have more mass to weigh more. If it has more mass I'm assuming you would get more velocity

288 piston offers more porting options

I did the same thing with a dirt dike. lots of fun till ya get hurt

I like the skirt.

 

[czar800]

A flywheel stores energy in tell needed like a drop in rpms. I can't see how a piston stores any energy.

I was wondering that the other night when I was reading about the older saws y'all were talking about earlier in this thread with heavier components. Would adding weight to a piston help torque?
Those old saws were torque monsters.

Yes, but it was just a theoretical question assuming Pistons were alike

 

[tree monkey]

lighter is always better

It would also change the balance factor of the crank, which may hinder or help.
