Re: Karizma/Karizma R Ownership Experience
The idle is extremely low and the sound may be due to connecting rod big end bearing...that said does the sound increase while riding ?..esp., when you down shift ? if yes then conrod big end bearing...if the sound is consistent even while normal riding and also while down shifting then suspect crank bearing. but for the crank bearing to develop this it must have run without oil..My suspicion is on the conrod big end bearing .Originally posted by Om1234 View PostSir please listen to this audio
Please Copy this link into your browser and listen the sound of my karizma engine
It is creating a thud thud sound on idle
Some say it is crank bearing and requires engine overhaul.
Some say crank is very strong of karizma it does not get damaged,it would be timing chain tensioner.
Bike has done around 30-35 thousand kms
One time half engine work,usha piston installed.
Average 40+ and pickup everything is proper.
No white smoke from exhaust.
Please give your valuable inputs.
Good Luck.Leave a comment:

Re: Karizma/Karizma R Ownership Experience
Hold the diaphragm against light and see if there are any small holes..if there is any you may have to change it...Regarding the Engine oil Shell AX7 is good...similarly the Shell Rimula R4 is good. though it is a Diesel engine oil the viscosity and additives are helpful in maintaining good engine cleanliness and keep the moving parts well lubricated... I am using it for more than 3 yrs with good results. Since it is a Mineral oil you may have to change it in 2 k Kms.Originally posted by jithin911 View Post@psr Sir, thank you very much for your valuable comments
I have checked vacuum hose, no block found inside.
I am able to open air cut off valve cover. Found diaphragm is not in good shape(Not Sure).
Attaching some pics of diaphragm and carburetor
Sir, which engine oil is good for 2004 model karizma?
Now I am using hero 4T plus 10w30 engine oil.
