Why did they stop making 2 stroke dirt bikes?

In six short years, the rules change made two-stroke bikes “obsolete.” Casual enthusiasts and industry insiders alike usually cite the march of technology and the need to reduce emissions as the key factors that brought the two-stroke-powered dirt machinery to its demise..

What happens if you put too much oil in a 4 stroke engine?

With too much oil in your engine, its fluid level in the oil pan will be so high that it can be splashed by some of the moving parts in the engine block, specifically the crankshaft lobes and connecting rod “big ends.” That, in turn, can whip the oil into a frothy consistency, like a well-emulsified salad dressing, …

What happens if you don’t mix oil in a two stroke?

But running a two-cycle engine with too little oil can actually destroy the unit. Oil helps cool the piston and cylinder by keeping them evenly lubricated. Without lubrication, the metals can melt and potentially grate against each other, transferring metal to and from one another and permanently distorting them.
