Motorized bicycle (Everything about 2 Strokes)

(((QUICK LINKS IN DISCRIPTION BELLOW TO EACH SECTION))) I just find some of the forum conversations on a whole other level at times lol! Like every DIY community you see many opinions and such on all topics. But some stuff is just wildly off base I feel at times! Granted there is always some wildcard that gets tossed in for some weird thing about a topic that actually has no godly reason to function but does! Most of the time that is not the case! So anyhow I see many off the wall 2 stroke ramblings that blow my mind at times lol! Or the photo of a guy with a 40mm carb off the side of a 80cc motor lol! then you get the few ask! Why does my bike suck after I put a windowed piston in? why wont my reed work? What plugs can I use? Next day you see the same guy with a plug for a formula one racer on top of his 80cc that melted down lol! Goes on and on! 00:30 Down Stroke 00:45 Up Stroke 01:00 Chambered Pipe 01:30 Four Stroking 01:45 Ports 02:00 Reed V
