Is a 2 stroke easier to fix than a 4 stroke?
Two-stroke engines are a much simpler design, making them easier to fix. They do not have valves, but rather ports. Four-stroke engines have more parts, therefore they are more expensive and repairs cost more. Two-stroke engines require pre-mixing of oil and fuel, while the 4-strokes do not.
How long do small 2 stroke engines last?
A current garden variety 600 twin engine in the popular trail/sport category can deliver up to 12,000 miles (19,000 kms) of reasonable use. Reasonable use includes using good quality injector oil, regular servicing of the exhaust valves and annnual clutch maintenance.
What does a two-stroke engine use instead of valves?

How long does a 2-stroke cylinder last?
A 2-stroke piston can last over a hundred hours if the bike was casually ridden and properly maintained, but an aggressive motocross racer can wear out a top-end in less than 20 hours of ride time.
Does a 250 2 stroke have more power than a 450?
Comparing a 250 2-stroke and a 450 4-stroke. The reality is 2-stroke bikes with the same engine displacement typically have significantly more power than their 4-stroke counterpart. So deciding between the smaller 250 2-stroke against the 450f is not unrealistic.

Can a 2 stroke engine run at the wrong time?
If the timing is close to TDC (top-dead-center) it is possible to catch the piston just at the wrong time with the result that the engine runs backward. This problem can only happen on a 2-stroke because there are no valves to be operated in a set sequence, as in a 4-stroke engine.

Why is 2 stroke carb tuning more important than 4 stroke?
Improper 2-stroke carburetor tuning will have a much more significant effect on a 2-stroke engine than a 4-stroke because the premixed oil lubricates the crankshaft. A rich mixture will cause poor performance, but a lean mixture can destroy your engine (over time).
Can a Piaggio engine be derestricted on a 50cc Scooter?
This is just a general note and depends on your scooter model. Also, this is only valid for the 50cc models. There are some bigger engine scooters with restrictions but it is very untypical for them to be restricted. Piaggio engines usually have the dummy pipe and the variator ring applied.
How big of a carburator do I need for a 50cc Scooter?
