Re: Hero Honda CBZ Classic

My charming CBZ*

Model : 2004
Self start variant
Seal Engine
ODO reading: 23K only so far in these 14 Years

Pics taken Date : 16 May 2018

Only changes made so far :
1. Front and rear Tyres(bcos older tyres had good gripping but it started giving cracks from the sides)
2. Clutch plate set(Clutch Center,Clutch Hub,Steel plates, Clutch plates) (clutch plates worn out as my bike was sitting idle for more than 1.5 yrs)
3. Battery (Self start variant) (bcos battery got drained completely beyond recharge as i did not used it for more than 1.5 yrs)

Need some suggestion guys, My bike is still in showroom condition ,but I have observed a slight drop in the pickup
Earlier I used to feel the instant rise in pickup after i continue to increase the throttle from its half way

but now that instant pickup is gone..

I checked with multiple mechanics here in Hyderabad 9/10 guys said the bike needs no changes at all as its in the pristine engine condition,

one mechanic said engine power is gone and needs engine work
and another mechanic said clutch bell(which sits at gear transmission needs to be checked as he senses there is a small play(ply) in it and needs to be addressed(lathe work)..

I am in dilemma if i should trust this mechanic and give my bike or no???

Anyone who has the similar experience can give me valuable suggestions

my other thought is to buy a ZMR engine and assemble it with alloy version??











to update it I had another CBZ* 2005 model without self start model
km run when sold - 28000
but sold it due to many bikes at home
seal engine again , with all stock original parts, not even a small cable was replaced

the pic was taken in 2014 yr


hope my bike posts makes many cbz lovers happy heartfully again

Re: Hero Honda CBZ Classic

Engine work after 23k in a well kept Honda is not common. Better to take it a good Honda SVC. I am a bit worried when you said that it was sitting idle for a few years. It could be just the tuning issue or probably carbs needs a replacement.

Don't trust these local mechs. I would suggest just keep riding it with a normal service if there are no obvious issues. All engines do reduce in performance with time. There's no way they would remain at the same level after 14 years!

Oh, forgot to say, that's one hell of a CBZ mate. Well kept.

Re: Hero Honda CBZ Classic

hi bro
can i hav ur cont no pls..

i am also planning to do similar modifications to my cbz star self variant model


my cont no is 9908653201
u can ping me

Re: Hero Honda CBZ Classic

i have a 2002 model CBZ classic black which has done 75k on stock engine. 23k is too early for Engine issues.

as for CBZ classic and Star the diffrence was the Cat-con was gone and from keihin carb they move to mikuni slide Carb to boost the FE.
few things to check if there is a drop in acceleration.

1. spark plug. as its over 10 year old . replace the spark plug if not replaced in last few year with the Original NGK ones.
2. open the carb and clean it with proper carb cleaner to make it perfectly like a new carb and check the idle and main jets. they should not be blocked.
3. air fliter
4. check with a voltmeter what amount of electrivity its creating at idle and at about 5000 rpm. at idle it should be about 12V and about 14V at 5000 or so rpm.

if all these check out good then check of any uneven sounds ( valve noisue- might need tappet/valve clearance ) adjustment.
run 1-2 round of Shell Rimula R4 of 1000 km each to clean up the engine gunk well.

that should do it... DO NOT OPEN THE ENGINE at 28000 km. not happening.
check the exhaust tip. do you see any oily deposits ( not dry carbon).
engine oil reducing over time ??

Re: Hero Honda CBZ Classic

you sure the cbz came with mikuni carbs,AFAIK cbz always came with the keihin pumper carb , but the late models were down jetted for economy and emissions

Re: Hero Honda CBZ Classic

the later models had some changes in the carbs..

old one was probably venturi . new ones were keinhin slide carbs...
i will gather more information on this but i am sure there was a change in carb and cat con

Only the carburetor was changed from the Sliding Type carburetor to a conventional CV carburetor.

wiki link : https://en.wikipedia.org/wiki/Hero_Honda_CBZ

Re: Hero Honda CBZ Classic

In CBZ star models the carburetor was changed.The star model did have accelerator pump.

Re: Hero Honda CBZ Classic

apart from the catcon and jets there was no change , the cbz always came with the same keihin oval venturi pumper carb

wikipedia has it wrong , cbz always came with the keihin pumper carb the star models were down jetted slightly

Re: Hero Honda CBZ Classic

the initial models had an exhaust with a larger dia hole, and then the dia decreased.. they probably added a catcon circa 2000 iirc.

and i've heard the star model had the accelerator pump removed to improve FE but have no way of confirming it. the star did not feel as nice as the original one in terms of acceleration..me having had the lucky chance of riding both of them in stock avatars when new.

here is a link from one of our members to the workshop manual:

you might want to go over the workshop manual that is posted above. especially the fuel system parts where they have given some troubleshooting info.
i'd advice you first get your petrol tank, fuel tap, carb thoroughly cleaned the accelerator cable cleaned/lubed and adjusted correctly, chain sprockets inspected and adjusted, before touching other engine parts.

Re: Hero Honda CBZ Classic

ihave both the cbz and star parts cataloge , only the jets were changed, also the initial models before 2000 came with the larger holed exhaust ,the 2000 onwards one came with the smaller holes,

Re: Hero Honda CBZ Classic

Thanks bro for the information provided

there is no such traces of oil deposits at silencer tip and also no engine oil level reduction so far

I did checked few things as you mentioned above :

1. spark plug. YES I HAVE BOUGHT A NEW NGK IRIDIUM SPARK PLUG,i will install it (Note: guys who needs info which model suits best for CBZ/Karizma the spark plug model is DPR8EIX-9, cost 647INR

2. open the carb and clean it with proper carb cleaner to make it perfectly like a new carb and check the idle and main jets. they should not be blocked.( I think i need to catch hold of mechanic to do so)

3. air fliter (i have cleaned it)

4. check with a voltmeter what amount of electrivity its creating at idle and at about 5000 rpm. at idle it should be about 12V and about 14V at 5000 or so rpm.(need to do)

also will use the engine oil mentioned(Shell Rimula R4 ) and see the difference

and update soon.

Also I would like to know more info on this line " for CBZ classic and Star the diffrence was the Cat-con was gone"

I am not aware what is Cat-con ???

this post will be a good information source for fellow cbz'ians too

----consecutive posts auto-merged-----

sure bro, I will go through the manual booklet and as mentioned to clean carb,accelerator cable and chain sprockets, and also few suggestions from theironhorse99
