Thanks PSR,Rockkrz,and Sibun for your valuable reply .


What I can gather from all your posts combined is :


1) I am definitely getting a very BAD petrol.


2) I am running rich (too much fuel but less air right ?)


3) carb slide gone or vapour lock.


4) tappet too tight .

Bike has done 40,000+Kms till now.


I will change the bunk immediately ….can I change the mixture setting myself ? cause I don’t have any good mech that I trust near me…so please tell me how to adjust the mixture correctly. About the vapour lock and tappet I will have to take it all the way to Chennai to check it…I don’t even know any good mechanics or Hero SC in Chennai …if you know of any good mech or SC please tell me



Is my engine permanently damaged due to the adulterated petrol? Or could it be resurrected like new ? if yes then please tell me what I should do

Thank you.

You can see detailed instructions in this thread on tuning your carb posted by Sibun if you turn few pages back.
Is your adultered petrol(or buuning oil?) causing too much carbon deposits on the valve seats, which may also contribute the symptoms you mentioned?
I have seen the same on my Splendor(which I've mentioned before here) and de-carbonizing the engine resolved the problem.

See i told you that the asbestos model brake pad will give more bite. Remember in a hero honda bike four things do not use original:-
1. Brake pads- KBX or ANL and brake shoes- ANL, ASK
2. Chain sprocket- Use rolon or diamond(TIDC)
3. Racer and Bearing- Racer use skf and BEARING use SKF or FAG. FAG have the best bearing in business.
4. Piston- Previously use to come of goetze or usha but now they are giving SAL( sunbeam auto limited), which are there own subsidiary and are worst in terms of quality.Use GOETZE, MAHLE or USHA but see that you find original as duplicates are floating in market. Usha is costliest among the pistons as it is made in honda foundry, japan and the rings are of timken corporation.They cost much more than the above two brands and there pistons have 11% silicon which prevents piston expanding on heating.
What you are experiencing is piston slap and it occurs because the clearance between bore and piston has increased causing the piston to rock side to side when absorbing the energy from combustion. Once it heats up the piston skirts expands and thus no sound from engine.

No your engine is not damaged as petrol goes till combustion chamber only. Clean the valves properly using a steel wire brush and petrol and lap it with the valve seats. De carbonize the piston and head and do a bit of research and go to a good petrol pump. Even you have to travel for 20-30 km still also go for it and fill the tank completely once a week.
From the photos that you have posted this is a case of ethanol mixing with petrol. Do not think the ethanol that you get as spirit, but these are ethanol which comes from sugarcane baggase and are cheap. So pump owners mix it for profit. But these ethanol are the worst for engine and cause gummy deposits.Even kerosene doesn't cause such problems as these.
For tuning your carburettor see my post no #4709.
But before tuning clean the carburettor and tank and fill good petrol. Also check the spark plug and if there is deposit clean it.

Good to hear my engine is ok .Took the bike to the nearest SC in Kanchipuram and the supervisor after taking a test ride told me there is no compression problem ...had to explain to him that after i push start the compression becomes normal but he said its running fine and to come back if the bike stalls or something .

PSR sir told to check if there are stuff in the spark plug as well so here i am attaching some pictures :






also the main stand broke today see this :



I forgot to mention this earlier i use gulf 20w 40 and i change it every 1K-1.5K ...also i change the air filters every 5 K instead of 10K.

here is a snap of the old UPS battery i am using in my bike... best battery for the Xtreme...way better than the stock battery :




I have not serviced the bike for the last 10K kms ...i just change the oil ,air filter,sprak plug,lube chain etc thats it .

1. The Spark Plug gap is too narrow..The CBZ uses DPR8EA-9 and the gap setting is 0.9mm , between the center electrode and the ground electrode..The plug shows that you are either running lean or running the bike mostly at higher RPMs..Correct the gap to 0.8~0.9 mm , run bike for 300 Kms and then post the plug picture.
2. The Gulf Pride 20w40 is a good oil and can be changed between 1.5 K ~ 2 k Kms....
3. You can also try Valvoline 20w40 Oil which I find to be better than Gulf Pride...
4. Air Filter change is based on how good or bad it is..ie., if it not dark yellow but turns to black then it is time to change the filter.
5. The UPS battery like the Amaron SMF is also a SMF battery, so should work well ..Looking at the picture I guess the battery you have is 12 Volts 7 AH battery which is good for the Bike...
6. I follow the same service routine as you do, except my Zen Mpfi Air filter after 5 K Kms still looks good for another 2~3 k Kms, and changed my spark plug to NGK G Power 2.5 K Kms before...
A word of Caution..DO NOT USE RED COLORED WIRE FOR NEGATIVE CONNECTION TO BATTERY.

Another mistake waiting to happen there psr'jee .
@Sarbanoxley - quickly cover the leading wires to the battery with correct colour electrical tape atleast , to indicate correct polarity ... it is easy to goof up on positive and negative terminals with bad bad consequences .

Guys, where can I find the connection socket for the head lights on my CBZ Xtreme ATFT? I'm planning to do an LED mod. Couldn't find it like the ones shown in this thread : http://www.xbhp.com/talkies/do-yours...e-simpler.html

Thanx pal.. thanx a ton.
Now I m thinking of changing the rear brake shoes also to asbestos type. Which one can I go for..?

Hey Xtreems,
Nice thread , keep on guys , geniune & technical discussions at there best. though i have gs 150r. this thread is more informotive.
Thanks

mileage

whats the mileage of xtreme and hunk?
my frnds say that mileage of hunk is just 35-40(hunk owners).
which is best from both?

Hey dear FM's, are you listening to praises to this thread coming from a GS150R user !

Thanks Vikshe, though I am rather a new member to this forum/thread.

My 4 year old Hunk(engine in not-so-good-condition) gives me 40kmpl in Chennai city commuting.
But many Hunk/Xtreme owners here are getting mileage of 50kmpl in city.

"Which is best" - this is too subjective, and depends on personal preferences.

i also get FE of only 40kmpl frist i use to get 45kmpl with my hunk

The Silver Bull on its 1st trip!

Engine oil for hunk

Hi guys my brother gave his hunk for 3rd service today ODO 5465 13 months old.
i had seen them putting engine oil from barrels(i think it was veedol) so i told him to fill it by himself.
So please tell me which mineral oil to be used and please tell me the whole procedure.
