Some 2-stroke scooters now have oil injection - the Yamaha Zuma for one - so you might not have to worry about mixing oil and gas. But yes, I agree with cpcardetailing: a 4-stroke's top-end won't have to be periodically rebuilt, and I've found that all of my 4-cycle engine tend to last longer and have lower maintenance than my 2-cycle ones. It's also better for the environment (arguably)...
Depends on how much you use them and how hard you ride them . And how smart the person answering this is but iw say the two stroke.
I'd say a 50 cc 4-stroker would last longer because the top end does not have to be rebuilt as on a 2-stroke engine. Plus it's a hassle to mix oil and gas.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
