The head mech is saying the "chik chik chik" noise which only comes when i raise the throttle is coming from the piston...he said it will go after sometime and if it doest go away he told me to bring it back...when i repeatedly asked what it was he said piston slap...i said if the pistons are moving sideways wont it damage the bore? he only gave me a blank stare and said your bore wont have any problem...he revved to see if any visible smoke comes from the exhaust...i think he knows whats wrong but he is not very forthcoming...just told me that he wont be opening the whole engine again to fix it and said it will go away by itself mostly....the thing is till he opened the head to fic the oil leak it was all fine...i am really upset first the oil leak now this problem .

Update : the "chik chik" noise seems to come from only the left side not the kicker side of the engine....one local mech is saying
its only "AIR" leaking from silencer and to tighten the 12inch bolt...i told him to show where the "air" is leaking ...he just told me just tighten the silencer a bit it will go away....another mech says the "chik chik" noise is coming from inside the left side crankcase cover...the one the head mech at SC opened recently to clean the metal shavings that fell through the timing chain hole...i didnt even tell the local mech it was opened recently...after they opened this side of the crankcase i completed nearly 200kms with no "chick chik" noise then how come it suddenly started after the head mech opened just the top cover yesterday ?

I googled "piston slap" and all the sources said it will go away after the engine heats up as the pistons expand...so took the bike on the highway and cruised for 25 kms @70-80Km/hr after which the engine was blazing hot but the "chik chik" noise is still present when i twist the throttle .

UPDATE 2 : Bike lost compression today ...the kicker went freely down when i tried to start it ...after kicking it like this 4 or 5 times it started suddenly...new bore has done just 5100kms even the valves are new ..sibunji you here ?

Sibun must be on leave considering the holiday season. He generally replies from office I think. Sorry, can't be of much help here, I don't know much about the stuff you posted.

Brother, 1) please check the tightness of your spark plug by loosening and tightening 2) check your air filter for correct fitting and report back.

Thats ok mate .



Tightened the spark plug like you said ....removed and refitted air filter too still the "chik chik chik" noise is present when i twist the throttle.

Took it straight to SC told GM about all the problems i am facing:

1) Bore oil leak from day one they installed the new bore kit(solved).

2) Head oil leak as no spares are available ...i had to go all the way to chennai to get it(solved).

3) Piston making noise at 5000kms

4) Compression loss

.he also said even if the bore needs replacement he will do it in warranty....keeping my fingers crossed for now

Hello my xbhpians...On 24/10/2012. .. Dusshera Eve i got my best present till date...my CBZ Xtreme...

[ATTACH=CONFIG]84089[/ATTACH][ATTACH=CONFIG]84090[/ATTACH]

Have been reading this thread for a few months to gain knowledge about various problems and caring methods..

It will be helpful if you people can tell me on how to drive bike till first servicing..

I have been changing gears at 3-4000 rpm and choke start and idle for 3 min in mornings...

I have been driving bike for quite a while...Gears are quite hard to engage...and it overall bike feels like it is strangled or power is not getting delievered...Is this common for new bikes...I learnt that i need to change engine oil at 150-200 km i.e 10W30 but which brand to prefer OEM or gulf elf etc..Plz help..

New bike particularly hero bikes will feel strangulated as they have tight tolerance and will take as long as 5k to free up.No need of changing oil and do the first service soon at 500 km.If possible see the service and see that they change oil from hero honda bottle and not from barrel.Gears will smoothen out after some time.

its 7.5k on odo, and about to get 5th service
my cbz is giving a lot vibration, started increasing from 7000, what will be the reason??

whats the average life span of sprocket and chain?
