Imaginary SG When should I do an engine overhaul? once every 2 yrs? Also, when should the chain be changed? Mine's a little warped liaoz.... wat abt washing abt valve, etc? So far i only know, must change engine oil, put 2T, lubricate chain, put petrol....
ah_tee SG no need to overhaul unless something major happen in ur engine or u got too much muny chain need to b changed when tighten until canot tigten liao, i m reffering to the chain puller has gone to the limit, but if still can tighten then tighten lor still got spark plug, wash carb, some bikes' valve no need to wash regulary, wad bike u reffering to?
ah_tee SG then i think not as often as aprilias, up to u, if u feel ur valve not opening ,then go, but if have then ok lor
