change of cylinder, piston, rings and gaskets

I will soon upload a video on how to change a cylinder with piston and other boards, and I got the parts.

I can not believe what I read, watch this

the things said today on our engines, people who talk without knowing anything and think that by criticizing someone or something as an environmentalist, these people are very wrong, please spend some time and read this:

Today was seeking information about the Motorized bicycles, for a change, and to publish something interesting for the readers of my blog, when I read this note from a facebook page, which is very wrong, where virtually debase and insult the Motorized bicycles with the assumption view that pollute more than any car. look at the article:

when I saw it I thought, "there is no shame that I do not like button", the best thing I could think to do was take it out with a comment long somewhat like this:
"Whoever wrote this does not know anything, he is ignorant, and it shows that never kayaked or motorized bicycle, or bicycle, first of all the pollution that is a lie, let me explain that the problems of unburned gasoline and that you say a lie can only occur when there is a bad carburetor, what good is this engine, is precisely how efficient it is in both gasoline consumption, imagine how much they consume other cars, besides you Are you a vision closed, as 4-stroke engines rely on valves, which to withstand pressures and temperatures of the engine are made of special metals, such as titanium possessing different alloys, many of these valve metals are extracted from mines, which explodes and contaminates lot more of which generate these motors also are exploited as African people for example, and this engine is 2-stroke has no valves, one is based on a simple construction and some metals aluminum cost, which do not generate problems in mines, and aluminum is number one material that can be recycled, so fijate carefully before speaking and you against something, or make a smear campaign, first you have to know, if you do not know do not talk!!! !! "

then I read the reviews and I came across one that said this:
"They are dangerous for the uses (brake failure, emission of toxic gases, risk of electric shock, poor weight distribution) and pedestrians who see them as something harmless but a stroke of these devices gets to kill. Cicloaxion never has supported this type of vehicles and prohibits censorship and its outputs, so is our commitment and act so "

I could not believe that people so ingenuous to believe these things to be discussed, how anyone can electrocute with a motorized bicycle? if the cdi does not get to throw anything, the current is despicable, the only thing that can happen is to give you a little shock, and all the things he says on consumption per liter of gasoline is not much time. for example, I have a motorized bicycle, which according to the strip 3.5 kg / km of pollutant when in a conventional car have 4 liters of oil, about two liters of acids and high in lead, which are not reusable materials without of which is built the engine of a car, for example titanium and many metal alloys that come out clearly from the mining and aluminum recycling as our engines, made almost 90% of aluminum, also would have to have model changes and the cars that go to desguasadero, with Motorized bicycles thing does not happen, well, I hope you is interested in this post, I think we have to defend our engines 2t and say what we think, thank you very much to all.
