bro's,

i'm using pulsar 200. i've experienced now is rattling noise sometimes when i start the engine in the morning. but when the engine is warm enough the noise will go away.

do i need to replace the cam chain? or the tensioner?

we've added a little on the tensioner to make it tight but still the noise is there. i think the tension is too tight now because i feel the engine can't rev up high too much...

any tips guys on solving this... btw, i have no base and head gasket...
