when riding normally i cant hear it, only during engine breaking that too at lower speed when the engine sound reduces....but it was not there before.only after changing ring piston it has started & bike also feels too unrefined

^^I think "unicornrider" suggested a good thing.. First get the tappets & timing chain adjusted (just to be sure) & if the problem persist then its surely the rings..Comment

adjusted my timing chain & tappets. still the problem persists. i can still hear the unusual sound at low speed when the engine sound reduces.....now its time to check the internals

Did you checked the timing chain tensioner?Originally posted by ShahriarXtreme View Postadjusted my timing chain & tappets. still the problem persists. i can still hear the unusual sound at low speed when the engine sound reduces.....now its time to check the internals
Is the sound heard during idling?

i think the mechanic checked everything by opening the head. i can not heard the sound when its in idle.Originally posted by Aneesh@4GHz View PostDid you checked the timing chain tensioner? Is the sound heard during idling?
i can only heard it only when i'm doing engine breaking that too at low speed (less than 30km/h)when the engine sound reduces....sounds like something is getting stuck & moving on

I'm not very sure, but to me it seems to do with the rings.Originally posted by ShahriarXtreme View Posti think the mechanic checked everything by opening the head. i can not heard the sound when its in idle.

If rubbing,then it can be seen on the cylinder walls,open and inspect cylinder walls for damages.Originally posted by ShahriarXtreme View Postsounds like something is getting stuck & moving on

ok i'll have to go for overhauling...to find out whats the cause. they said there's something called balancer beside the clutch part which is the main reason for vibration if not adjusted properly.they said this because i'm experiencing heavy vibration after ring piston change which starts right from 4k rpm & after changing ring piston. is it true?
again during overhauling every issues can be found i guess such as loose rings(labor charge+engine oil+gasket)
. by the way this job will make a hole in my pocket but i have to do this anyway
