prefer the 4 stroke for sound, reliability and not having to worry about mixing fuel. that and its at the top of the learner legal power anyway so theres no benefit to going 2 stroke

4 stroke learner legal = Yawn.

2 stroke for sound, smell and poweband and win.

Fuels all premixed anyway nowadays.  Just fill the oil tank and it does it for you.

There is nothing quite like the smell of comp 2 in the morning - or coming on to the powerband !
