I've been tidying up my new to me Xmax 125 over the last month.
Pretty much there, only the swing arm and main stand to respray now.
Anyway I bought a used air filter box from eBay, to replace my tired looking one.
Opened it up to find an immaculate K&N air filter inside....nice.
Anyway washed and oiled it just in case and fitted today.
Very very little difference in feel, made be a bit more grunt once at max revs, but not much.
Nice difference in sound, at idle it's the same but at high revs it just sounds that little bit angrier with acrpovic exhaust.
Main point is I've got a free use for life filter......nice.
