Smallest & quickest engine re build we've ever done

First time working on a 2 Stroke engine sparks some interesting questions. Why is it smokey and run terribly? Why is it low on compression? Why are 'we' working on something with less than 4 wheels ?

Those piston circlips are often know as Ping-Fuckits. Ping is the noise the circlip makes and fuckit is the noise you make as it flys off into the far corner of your garage, never to be seen again.

Hell yeah, rock the go-ped! I only sold mine not too long ago in peices. Between snapping the handlebar shaft bolt, and breaking the exhaust housing mount on the cylinder from hitting the expansion pipe on the ground doing donuts... it was always a work in progress hahaha. With the hi-po carb, k&n filter, and that expansion pipe, that baby little piston used to be able to throw you off the back if you weren't leaning over the handlebars 😅 Cool to know that Zenoah is husqvarna now, that's super interesting!

@garchompy_1561 3 ай бұрын

for 2-strokes, turbos = no, but superchargers = yes. I see usually centrifugal superchargers, but with it being carb, you might have to work out a whole preasurized fuel system, which im not sure how you would do (since using exhaust pressure, like some RC car people do, with this wierd frame exhaust is probably a no-go) unless you add a pump, whick then needs a source of power and so on. definately a can of worms if you try to do forced induction here.

This is cool reminds of the days when I seen my licence as a right not a privilege young and dumb so found myself having to purchase a push bike that already had the motor strapped to it....were I bought it you had a choice of 2 Chinese 2 stroke motors either 50cc or 80cc naturally I went for the 80 they looked the same other then a black or silver casings....back then the popo didn't know what to do with em legally and mine would sit 70 to 80km on flat road no problems and even got ya up the hills without pedal assistance....all I can say mate take no offence being a big bloke those scooters are death traps and hope you have a good dental plan those little wheels will grab anything especially at speed they will throw you off believe me been there done it....just a heads up bro that's all...was a cool little video mate cheers. I think the law in nsw is anything 50cc or over needs a licence and rego anything lower is fair game some police are full on about it but generally wear a helmet put along they tend to look and leave alone....rip around getting attention they hammer you with everything....

@ryanhunter7365 3 ай бұрын

Your gut feeling is right about the ring end gap. Piston has to face correct direction so that ring end gap doesn't hook a port.

@BennysCustomWorks 3 ай бұрын

It can’t face any other way. The ring is pinned and it’s pinned at 90 degrees to the gudeon pin and the piston id mark points to the exhaust port so it can’t go anywhere else.

@ryanhunter7365 3 ай бұрын

@BennysCustomWorks sounds like you got it right. Piston mark always goes to exhaust. Usually if the ring end gap has to pass over a port there is a bridge across the port on the cylinder wall to stop it from hooking a ring. Maybe it just not an issue at that performance level or bore diameter. My background is in outboard, snowmobile, and dirt bike 2 strokes. Haven't worked on anything that small. Glad she's a ripper.
