Anyone can spare some tips or advice on how to make the engine run at optimum performance? I just overhauled the whole engine recently, and am trying to know what simple mods are the best for this engine. Mated to a 3spd auto gearbox btw. (I know the gearbox sucks)

Really need some good advice to make it a worthy engine :)

Minor mods such as air filer, cold air intake, extractor, exhaust will do. Your ride is running in AUto gearbox right

u mean mod on that carb?
from what i know from old school mod guys, they said 4g15 carb is a good upgrade for thier engine, n its can support bigger cc then 1500cc.. so actually ur carb is more then enough, just u need a people/person that really experience tune it, that's all..
if u wanna change to other carb, that another story bro.. eg side-draft carb, down-draft carb etc.. proton is down-draft carb..
