hey.. wanna ask something.. yesterday i do some research in youtube and google.. LOL.. on carb and block.. for port & polish.. some say according to their pantang.. polish the block is not good cause some oil tends to stick to the wall of the shiny surface..and not complete combustion..and its better to stick to unpolished wall.. ? hah..
and i finally understood how engine works.. 2 stroke and 4 stroke..wat i can conclude is good spark plug and bigger piston + block gives more power... cause bigger space for air and oil and better sparkplug for more spark for combustion... hmm.. interesting... but wat matters is good quality of block to prevent overheating..if not good.. no use also got high power as cant bring for daily ride..
for stock block.. ppl invent the engine for lc is through careful R&D by mechanical engineer..measuring the heat produce and find a good material to overcome the heat and etc..
and yea.. bro charge.. the racing block and stuff... ppl simply create only ar...? thats why cheaper than original block...? i was wondering about this type of block..
and is bigger block produce more heat compared to stock block..? i mean cause bigger block got bigger bore ma right...? or is it the same..?
and can polish the carb bigger ar..? i mean the air flow hole for more air input..
