They all have problems, they all have pluses and minuses. Easier, and more cost effective to rebuild a 2 stroke, better longevity with a 4 stroke. I have had both, and honestly dont care anymore. I buy the best chassis for my riding style. I prefer a 2 stroke. This was in Dub Sunday... Newer 4 stroke Doo. Ran good the day before, put in heated garage overnight, didn't want to start, or run well after it started in the morning. Back fired a few times, then flames started coming out from under the hood.

The Big Paid Cog turns slowly.

Whatever!     Blame the volunteers?            

New stuff isn't as reliable as old stuff that's for sure. Zero engine blew up at 364 hours too. 😂  4 stroke have better re sale value typically too, especially with higher miles. 

There’s a reason folks buy 4 strokes.  That right there is it.  5000 km.  That’s ridiculous.  Never again will I look at a 2 stroke.
