its most probably due to low viscosity of the fully synthetic oil (too cair)... so higher revs can cause scratches on block if in running in period... but cheap engine oils hav higher viscosity but wont last long... need regular oil change..   correct me if m wrong

bro, the muffler is 100% fake... so dun waste ur time... lol.... bout changing valve springs... requires removal of the head... so need EO change n minimum of 2 hour time for installation n setting... go for trusted brands like BRT, TDR, ride-it, etc...
