Yes the upper and lower half are independent, but they slightly overlap each other at the place they join, if I remember correct.
And Yes, the upper cover is firm with two bolts.

From Dazzler's pics from google, I see a bolt at the front(near the front sprocket cover) and the rear bolt you mentioned. We need to see on the spacing of these two bolts, to make sure if it is a direct fit on Hunk/Xtreme. As Ashwin mentioned, the dazzler/FZ covers are light weight as they are not metal.

No need to lube gearbox, it is lubricated internally by the engine oil we pour in...

Then why do they say use Gearbox SAE90 grade oil for the chain? I know the question holds a slightly irrelevant outlook. Thing is, since everyone was asking us to use Gearbox oil for the chain, I expected the gearbox to be lubed separately. Either way, thanks.

Boss i did of R & D with my xtreme which lacked GRS.
1. pulsar shock worked fine. had good play but longer than stock.
2. hunk shock smoother than stock but longer than stock.
3. Replaced it with the thinnest oil worked for front fork will try it for rear one.
I would say dont panic regarding shock issue. try and ride other bikes with grs.

i read some where in wikipedia that

Earlier motorcycles gearbox and engine are two different units. like 2stroke the engines lubricated n cooled by the oil in the pertrol and gear box by gear lubricating oil.

they are 2 different oil. later now as gearbox, engine .. comes as single unit , special oil which do both lubrication and cooling of engine an gearbox.

that is why still we use gear box oil to lubricat the chain. some svc use used engine oil to lubricate the chain

Ummm, who are you referring to?

Engine oil to lube the chain is a strict no no. Moreso used engine oil. Thanks of the additional info!

Why so..?
I ve used engine oil, used engine oil and
even vegetable oil on the chain.

One Sachin ! One Rossi ! One CBZ !

Hello fellow Sprinters !

This is one bike I saw and fell in love with at first sight ! Probably in my 8th std (i guess '99-2000) when I saw this beauty in flesh for the first time and I fell in love with her. The initial attraction was undoubtedly the stunning looks and rear tyre which made her look like a showstopper supermodel on the ramp. I don't recollect much about my drooling experiences, but i strongly remember it was in class 11 that I had decided - the CBZ will be my first motorcycle, NO MATTER WHAT!

A classmate of mine had this red beauty and flaunted it outside the college gate. It sure attracted a lot of attention from both the sexes. I was a bit jealous. Years flew by, but I never pestered my father for a bike for reasons unknown. I never had my own bike, neither during my junior college nor during my engineering. During engineering, a bike wasn't a necessity since i traveled in train. It was 2004 when i started with engineering, the era of the CBZ Classic was almost coming to an end.

I realized I would never be able to own a brand NEW Classic (which I do not regret ) and if i decided to go for a bike, it would have to be the new CBZ Star (which I did not like) or the new pulsars which actually never appealed to me till date. And to top it, I had 'promised' myself that my first bike would be a CBZ. So, the search for a well maintained CBZ Classic started. The initial search wasn't very intensive so didn't come across any sellers. When the search intensified, I found only two kinds of people - the ones who had splurged their money on that era's best bike, abused it and left it in a pathetic condition AND the ones who'd taken care of their machines like their girlfriend and were not ready to part ways with it!

I finished my engineering and a year in my first company. Switched to my second company in 2009. By the end of that year, I had literally searched every corner of Pune and Lonavla and personally checked more than 80 bikes (no exaggeration) before I came across this bike in my hometown. A little brief about this bike - a blue colored classic bike in complete stock condition, ridden by a 50-year old guy for about 8 odd years only inside the town, never exceeded speeds over 50kmph and less-than-regularly serviced by a average roadside mechanic. I met this arrogant old timer a couple of times and showed interest in buying the bike. Initially he ignored because he wanted me to give him an offer he could not refuse (sorry, couldn't help but using this famous Godfather quote ). His arrogance pissed me off and I was too egoistic to talk to him again. But, I realized that the machine in front of me was worth easing my ego for it.

After much discussion, he made an offer of 25k and I knew it was worth it. (Financially literate bikers would criticize me for my decision, but I believed it was worth it.). I tried to negotiate a couple of grands thinking I would use the money to give it a much-needed make-over, but the guy was adamant and stuck on his price. I waited for a day and the next day I came back, paid him his 25Gs and rode the bike home. My first ride had arrived, my 7 year dream came true and my joy knew no bounds. I finally owned my first bike - 2001 model Hero Honda CBZ Classic blue color !

Since then, me and my baby have been for each other. And the journey will continue for years to come. And I have even given her a name - TurboKat!

The very idea of lubricating a chain is the idea of longevity. Of the chain and of the lubricant. Engine oils and vegetable oils (Seriously? ) are of very very low viscosity, which would explain why they flow so freely. (10W30, 10 indicates how viscous the oil is at cold temperatures and 10 is not a very high number). That way, the oil inherently is dislodged from the chain by virtue of Inertia once the bike starts moving. You probably can't see this happening because of the chain case While SAE90(Gear Oil, the 90 here indicates the viscosity and 90>10) is much, much more viscous and is held onto the chain a lot more that conventional engine oil. Anyway, the retention capacity of the chain with respect to engine oil is fairly low. That would explain why we have special Chain Lubes to serve the purpose.

Hmhmm.. u are right buddy. Lighter oils just spin away from the chain.
Once I had to clean the chain with a mix of kerosine+veg. oil (which mom uses in her sewing machine ) The kerosine stripped the chain clean nd I was forced to use the only oil available - veg. oil
But the chain was simply dry within 10 kms.

Haha, and you would've had a lot of grime on your chain covers as well.

Experience is the best teacher!

Great Experiments (with vegetable oils!) going on in this thread!! Surely!

Some insight into chain maintenance pl? And 'sound' of a clean and lubricated chain? I'm curious now! I wanna 'hear' the difference. My baby is just 1k kms young so might take some time before I start some DIYs but I would really want to 'hear' the difference of how a clean and well lubricated chain sounds.

You make me remember the days when our guys discovered locally that using coconut oil is better than 2t oil for scooters/autos/max 100s etc !!!!
(No offense meant !)

And some guys continued using it for sometime, finally stayed away when coconut oil became expensive than 2T

(Between I am also basically from Kerala, Thodupuzha to be precise )

i guess you are referring to all BOSSES here !

Why you had to try this, coz you were unhappy with Xtreme shocks?
Anyways, I'm eager to know about this. Of Pulsar and Hunk shocks which one was the best? When I rode my friend's pulsar 7 years ago (time when Nitrox introduced in Pulsar) it was smooth like anything, it offered plush ride i ever had in my life on a motorcycle. My Hunk's shocks are bit stiff now(probably because of age), but it is considered to be one of the best suspension in 150 cc category.

Replacing rear shock oil with thinner one won't be an easy task, you would have to give it to shock re-conditioning guys. Re-conditioning shocks are not always recommended, as they will not be restored to their original condition.
If your Xtreme shocks feel stiffer, replace them with new ones?

AFAIK, using engine oil for lubing chain is absolutely fine, thought might not be effective as chain lubes.
But "used" engine oil is a strict no no, as it would've already lost the viscosity by being "used" in the engine.

i really enjoyed that sound after my second service.

coconut oil + kerosine is a good solution toget instant glossy effect.
you have to be an expert to get best result
i use it on my bicycle and sometimes on my cbz
