Plus 21-4c vs ninja jx 21 BO1A.
I'm planning on buying one of these as my first engine for the season so I'm wanting the engine that last longer easier to tune holds a tune and has great power. This engine will go from buggy to truggy every now and then but mostly will be for buggy, I'm really looking for a nice engine that will last LONG I'm sik of buying engines.
Thanks in advance!
