Re: 2-Stroke vs. 4-Stroke
I think its open to interpretation. 2 strokes need to be rebuilt more often than 4 strokes. That is theoretical, and is subject to being used under similar conditions.
Jetting is way more important on 2 strokes. They do not have as much leeway as 4 strokes. Its important to keep the air filter clean, as a cloged one, can richen the mix.
One could say that more 4 strokes require MORE preventative maintainence, in that they have engine oil, and an oil filter to be changed, valves to clearance, and timing chains, to keep the slack out.
Most 2 strokes have radiators, water pumps and hoses that wear out. Most 4 strokes do not.
Wow, maybe 4 strokes require more maintenece less of the time, and 2 strokes require less maintancece alot more of the time.
