All pakistani altering peoples dont alter your honda or chonda bikes if you ask a genuine mechanic hard to find here in pakistan or ask a chinese engineer he will say don
t mod any bike part without bundled knowledge of it,i modded my bike after years of research on cylinder volume and cranskshaft balance force relation even with that maths and many other things i dont modified it because i don
t had money to do so otherwise it was a wholly researched thing,it was modding a yamaha yb 100 with bigger bore of 200cc^3 with Superior engineered crankshaft the bore has a total force of 500Newtons and weight required to balance it was 450 kg or 600 kg..So mod But it will broke earlier or will heat up much faster not in case of mine,do research you have google than mod,for me it was year of research but ended up having no funding.:o
