Like some racing video game, port and polish also got few stages to modify powerband.
Stock head I dunno what it looks like, but some polishing may be good also.

polishing ok la but porting is nid find bak the forman tht know setting lo.. if porting salah will lost power or hard setting

u use what head for lc? for 30k milleage what else need to change?

oh yes? porting need good foreman?

yea ... if not cant setting one , timing not stable , power lost
etc etc

grind valve and change tappet mayb. if valve makan/leaking change or lost power.

I thought it will look good on black coverset..

i think is swallow samurai

no. not samurai. dat tire looked exactly the same like maxxis. cant tell the difference.

doesnt stand out as much as white.

what u mean by grind valve, i dont really understand, what you mean by valve makan?

grind valve like sanding down the valve to make the surface nice again cause the valve cant seat properly ... normaly grinding nid use 2 type of sand
1 kasar 1 halus ... after kasar then halus use some time to do it tot... do it before on ex5 on helping my uncle hjaha

if you mod then chances of valve makan is higher. the tip of the valve gets chewed off.

my lc is stock, so grind valve and polish will be nice? anyone?

My bike use standard engine head, no valve, no cams, only spark plug hole.

Grind valve is when valve is damaged, and no money to change.
Porting means make the intake and exhaust hole and airway bigger.
Polishing just means make the airways smoother.
Cam lobe makan - Must replace. Can be caused by overheating or racing valve spring or low grade EO or EO too good.

Stock engine, don't do anything modding is the best. Bigger exhaust tail pipe is the best mod for stock bike.

If you change cam, you can consider polishing and exhaust. Spend all the time to make the new cam setting nice.
Later then big bore kit.

for better perfomance 1 shot go in is best , chg 1 by 1 comfirm expensive to mode... btw jus buy kips 150 if wan speed ... around 3k mroe for lc = x2 lc top speed haha

KUPPY FOO LAT DONT DDLY
