Hard to say if the material type differences from thin to thick would be less/more resistance to getting hung up on a wide port?  Steel vs. Cast

Less friction losses.  Also a bit less compression at cranking speeds (easier to start) supposedly....

the main reason for a thin ring is cause of rpms , once you get a motor to turn enough rpms a thick ring will break and yes it will break all to hell , a thin ring can stand alot more rpms but what happens on even the 2100 thin ring piston is the ring land between the 2 rings will break out of the piston . Now I'm not talking a gas saw I'm talking alcohol/nitro , the best world for a racesaw is a single thin ring

Cale just look at Chris's 395 alcohol saw , on muffler it will run for ever , on pipe in 8 by 8 its ok but once you but it in say something bigger than 12 inch round the thick ring piston breaks just about ever run

boost ports are junk but something they look great , outside transfers are way way better at making flow plus gives you enough room in the cylinder to make your ext and intake port the proper size , only problem with outside transfers is they need a way more fuel cause you put alot more air threw the motor so your going to need to do alot more carb work

Got the 2100 put together and fired up today.
It was 35 degrees out so just fired it on pump gas, still surprised it even started.
This thing pumps a ton of fuel, with screws out 1/4 turn it was still rich.
Idled, reved up and restarted

It's got a 10 tooth on it and I've gotta cut a bar down to fit it.
It'll be a while before it's warm enough to run it on fuel.
