i was skeptical tbh.
that little 'leong cha' potion worked immediately! idling is smoother (Elton, idling now dammmnn smooth, at 700-ish rpm) engine is alot quieter too and as Elton used the precise word, alot calmer.
lets see if with threebond and revo, my full tank range can improve by another 50-80km

thanks Elton!
