2 Stroke vs. 4 Stroke
|The choice between 2 or 4 stroke engine is dictated by personal choice, riding style, weight load and terrain. If your primary purpose is commuting, or require a faster top speed – you may be more interested in a 2-stroke. If you pull a trailer and/or anticipate cruising at slower speeds, you may be better suited with a 4-stroke engine.|
|Smoother running; faster speeds, lighter weight, runs cleaner at faster speeds.|
*** Never mix fuel rich even on break-in! Always mix 50 to 1 (One US gallon gasoline to 2.6 oz Two- stroke mixing oil). For Air cooled engines; synthetic blend – not straight synthetic oil.
|A lot of low end torque at slower speeds, engine runs clean cruising at slow speeds.|
*** 4-stroke engines contain shipping Oil – Add oil before running engine (less than 3 oz) but don’t Overfill – keep oil level below Full indicator on dipstick. When checking oil level, Push dipstick in – Don’t screw it in – just push in, like checking oil level on auto dipstick. Check oil level when engine is cool, before starting or allow engine to cool a minimum of 5-10 minutes after running, before checking oil level.
Too much oil will cause oil to be sucked into the PVC valve, won’t hurt the engine but will make a smelly mess till it’s cleaned/run out. Hard trail riders may want to drop oil level even lower, i.e.. half way between Full and Low indicators on dipstick.
