ageing motor & fuel consumption

[hoga]

dose a 2 st motor use more fuel as it wears out hoga

Yep all motors will when they get tired from age.
For example a 2st putting out 50hp at 200hours with the carbie butterfly open 3/4, when old like 2000-3000hours it may only output say 47hp with the carbie butterfly at 3/4 open.
But really it is hard to notice the difference in consumption because of the varied conditions they are used under each trip.
Honestly if your engine is under 1000hours old it is less than say 30 in human years. Tuning alone makes a big difference. cheersfnq
