Leave the bottom ring off or you can notch the ring and put the ring gap wherever you want. Lastly you can remove the pin, drill a new hole and use a drill bit one size larger than the hole you drilled drive the drill bit in and cut it off to make a new pin.
I've seen that too, the stihl 036's I'm rebuilding and some weed wackers come to mind first but I bet lots of others have it too. Is it actually particular to Stihl, vs Husq's etc., or were you saying them just as an example?
@@ghettobikelife8833 Stihl used it on many models since their design and layout of using dual ring pistons and having the piston drop low enough. Saws like the 200T had the ring drop down into the intake but didn’t use a tonsil. Husqvarna didn’t need it since they were big on single ring. I believe there was older brands that used it here and there but Stihl used that design a ton. On the Stihl 034 the 46mm cylinders had it but the Super (48mm) didn’t use it.
I did my phantom experament like ERT said to so far so good lots of balls I can take off from a dead stop try not to because it eats up them cheap clutch pads but in a pinch just like a motorcycle and I weigh 250lbs give or take a few lol
I got a gen 3 and replace piston with meteor brand 046 piston. It has a wider skirt but narrower ring pin placement, closer to intake port. I marked where the ports and transfers were when I put the cylinder on. I also chamfered the end of the rings cause they are razor sharp. I've got roughly 100 miles on it pulled the intake off and everything still looks good.
You say exactly what I try to tell everyone in a good inglés 😂 you can run this use no windows and use the original carb you be more happy I have 7 tanks aready no problem
So glad I didn't buy a Phantom 85......I'm thinking for a decent,hopefully reliable, budget build with decent power- use my mz65 clone pipe $45, gety a YD100 engine kit $120- ported, with better wrist pin clips, do a 3rd intake transfer port, G2 Reed/VM22 carb $50 with a balanced crank, port match case & cylinder.....It still won't be as fast as a Phantom 85 (52mm VS 50mm) but maybe get close.
I bought all 3 gens. First was cool but the bushing was trash. Second was cool it would catch rings and the third didn’t last 3 miles before a ring caught again. I was able to keep the 3rd one running with just top compression ring. If you recenter the stud hole I think both rings would catch
Yeah my plan was to also run just the top ring, but mark the piston where the end gap is with a marker and rotate the cylinder in the studs until the piston mark is in the narrow 'vertical slot' between the transfer and intake ports
@@motoredbikemadness2061 I honestly don’t remember how the first gen ports looked. But I remember the 3rd gen would run great straight out of the box I was doing 45mph with a 36
@@justanothermotorizedbikech5138 damn I used a 36t also with my 1st gen and it would probably barely hit 40mph. But I had to drill the main jet to make it run right so it ran a bit rich after that
I switched out the piston for a stihl 52mm 044ms440 big bore piston and rings and 12mm pin bearing then I put my own window in the piston and has been working fine got the idea from ERT channel they hold a speed record on a phantom 56 miles and hour with no window piston one of my phantom has almost 500 miles on her and still working the other has 50 miles on her working fine had a little issue with cylinders getting hot switched to the 2 stroke oil mix they recommended and running cool now The oil is Valvoline multi purpose 2 stroke oil they recommend racing 2 stroke oil Valvoline but you won't be able to find it so they said go to the next best thing which is the Valvoline multi purpose you can find it at autozone and these phantom engines love oil
Yup I’m probably gonna use the ms440 too, only problem is the ring might still cross over the port if I can’t rotate the cylinder enough. Even if it does, will probably run fine, just best to not have the end gap near the ports how the stock phantoms come
@@motoredbikemadness2061 that's why everyone is switching over because they don't cross over the ports at least mine don't go to ERT Ellis racing team channel that's where I got the idea from
@@mikemiller3303 yeah I bought an 044 piston after seeing ERT’s vid, but I bought it because there was a 10mm pin version, so that I could use the normal 10mm pin+bearing instead of the 12mm bushing. But the end gaps are still crossing into the ports- all the pistons I showed in the vid (044, 038, phantom) did. But mine is a Gen. 1 phantom, maybe the cylinders are different. Which Gen is yours? Also- if you’re using a 12mm* pin 044 piston but I have a 10mm* pin 044 piston, maybe your ring locating pins are in a different spot
@@motoredbikemadness2061 I have gen. 3 cylinder and a yd100 bottom half which has a 10mm pin bearing if I used the bottom that came with it it was 12mm and ERT said to use the 10mm so that's what I did ask him he's got a video of him going 56 mph mine has almost 500 miles on her no ring snag so far 🤞
Which one, the new one I’m using instead? It’s a stihl MS380 chainsaw piston. But it wasn’t a perfect fit, you’d need to stack 3+ base gaskets if you can’t machine down the height like I had to. I should have used an 044 piston which at least is more common/cheap than 380
@@cxd710 not to mention that having the pins on the exhaust side is probably even more close to / overlapping the port. But if the locating pin is in the right spot, as if it was designed and built custom, it could be the ideal option to have the pins on the exh side. Sctually I think I've seen it. Keep in mind most high performance 2 strokes eg. dirt bikes have a metric ton of transfer + boost ports on the intake side

Stihl is known to have rings drop into their intake ports. They had a “Tonsil” built into the intake port to give ring support.

Have a link where to buy that I has the same problem
tick tick tick tick tick...just a matter of time

This is exactly why im thinking ebike, spend hard earned money on something thats not gonna work, ive bought one and blown twice now its in my attic
Just don't buy a phantom 85 lol you shouldn't have many problems at all with a traditional 66/80cc motor, if there's no factory assembly flaws

Where can u find a ported yd100 for $120m

performance wise, did they run any different? Do you think the port shapes were changed and that's why the first gen didn't catch rings as much?

I was thinking about turning the whole piston around so pins are on exaust side
Bad idea you need your windows for your intake
Won't matter if your cutting your own window of you run one at all 🤷♂️@@cxd710

If you get a chainsaw piston and do the window yourself, you can put it on whichever side you need so doing what you said could still be an option

No problem, thanks for sharing the vid! Haven't started modifying it yet, but lots of ideas!
