Query Approved.

**jd666** · 12-29-2009, 12:10 AM

if u really wanna throw the book at em. Tell em to bring out the service manual of the unicorn, and check what is the service wear limit of the clutch plates, and warpage limit also.

Measure the same of your clutch plates using a vernier, and the warpage using a feeler gauge. That should answer their query that youve been dragging the clutch or something.

Also a physical indication of clutch wearing out, is when you are riding maybe with a pillion, the engine revs increase, but the bike does not catch speed that quickly, as if the engine is slipping on the clutch. Thats an indication as to the clutch being worn out.

Also get the carburettor cleaned, tuned and adjusted properly. Check tyre pressure, and also make sure the condition of the air filter is clean, and that the gap on the spark plug is within specifications. Also the plug should be clean.

Thanx jd for the help.
Yes i felt that the pick up with pillion is low these days. I will check the tyre pressure tomorrow(did that before 2weeks) and still if the pick up doesnt improve it is the clutch plates right?
But the rpm levels are same as before. (eg: it is 50kmph in 5th gear at 4000rpm for unicorn. It is same as before).
If it is the clutch plate worn out, do i need to measure the wear and warpage? Can u pls tell something more on wear limit and warpage limit?
i will ask them to clean and tune the carburettor and also the air filter during next service.

watever u do clutch plates,wont wear so fast in a unicorn...the problem might be something other than that...considering 42-45kpl is good mileage on a unicorn..

**fayad555** · 12-29-2009, 03:32 PM

my bike ran out of fuel when it did just 51kms in reserve. ie on 1.3L petrol. so fuel effeciency is just 39-40kmpl, which is more than 10-12kms lower under same riding conditions..

**ali_xbhp** · 12-29-2009, 06:25 PM

we only have to go to them coz of the warranty n free svc,
my bike is still the same ...gears slip a lot,,low mileage n pickup is low now,

also consider what jd666 suggested

Did you find out what was the actual problem?
Or you might have did a higher speed during the trip. Shine should return 55+kmpl when rode sensibly.

**shubhanker** · 12-30-2009, 01:07 AM

try changing the air filter this service..
hope it helps
otherwise i can't think of a reason for low mileage in a new machine
check the air screw in the carb, should be open 5 half turns
u can see it looking at the carb from the left side of the bike
it lies along your sight inside

**pradeep reddy** · 12-30-2009, 01:27 AM

my frens stunner gives 43-45kpl and my unicorn gives 31 to 34kpl..dunno wats wrong these days every1 complaining about mileage in honda bikes...i have tried almost all svc ,no one could find out wats wrong ..with no other way am just filling more fuel...

svc guys say every thing is normal....fk thm

,,,
but i m still faceing thoz probs,,i din find what the prob is ,,but i will b4 the 4th svc,,and yes i did ride my bike at higest speeds during the trip

low average sucks

hey bro,
running the bike on top speeds on a ong distance journey does not cause to drop the average. Coz i had gone to goa on mu pulsar 150ks and it gv me an average of 45 - 50kmpl wherein we were speeding between 70-95 kms per hour.

i guess u chk the carburetor, get it cleaned and tune the bike from a local trusted mechanic as somtimes the showroom guys can be useless, as they dont want to help the customer by goin a mile. instead they jus want to do their routine work and jus shoo u off their backs.

try and soak the air filter in oil and then use it.
also chk the spark plug. also chk the idling of the bike on standby mode.
if too much idling is there, then reduce it, the setting should be around 1000 rpm (experts please confirm this), also try and change (if possible)
the clutch and acceleration wires.
also could u confirm whts ur rear tyre size, have u changed them to a bigger size???

jus try these buddy, and ofcourse if the clutch is slipping then you will have to change them with the oil .

fuel effeciency will be lower at higher speeds.
idling speed for unicorn is 1200-1400rpm.
why to change the the clutch and acceleration wires?

what did the ASC reply? Ask them to do a mileage test..

So i got my bike back and mileage hasnt improved..
Can we check ourselves about the clutch plate wear?
What are the other symptoms of clutch plate wear?
Can this happen if the clutch cable was tight or for any other reason ?
Pls help me out

two statements contradicting... please clarify...

as for your first query,
drain the oil from and remove the clutch assembly... check for the smoothness of the plates... if there is wear, it must be even... uneven implies the plates are goin for a toss..

this is not a symptom, though it leads to clutch wear:
it is usually the load on the clutch rather than the engine which causes max wear... that is riding on higher gears at lower speeds, precisely lower rpms....
also is the engine oil you using is of the specified grade?

as for the third query, i too am in need of a solution.... my clucth cable had become tight and i changed them(due to recent rains)... the lever is butter smooth now... but from the day i've changed them, i'm havin problems with gear shifting... its really gettin difficult to downshift after 20-30kms of running....

This is what they claim to have done.

When i got my bike back, i checked the mileage myself and found it be low.
