And regarding monoshock then let me ask what is wrong with the present shocks. The GRS is a perfect balance between handling and comfort. Or is it because monoshock is in vogue so lets get that also. During the track day by overdrive in 2008 annual issue by overdrive the extreme was fastest on track even though unicorn had a monoshock. I ride 170 kms non stop. I have never felt the need of it.

Friends,

Moved to a new job in my home state Kerala. Got NOC from Chennai RTO for my Hunk and bike has been couriered to my native place in Kerala.
Had a casual ride today to some nearby places where there is nil traffic

Now, I've owned Unicorn 160 and Ride quality wise Hunk was much better. Hunk was able to absorb most potholes and bumps without transmitting it to my back and was able to provide pliant ride, whereas Unicorn transmits EVERY single thing to me and i feel it's bad than Hunk. Mono-shock and seats were MUCH better in old Unicorn. Mileage is better than Hunk as of now. Quality of switch gears is better on Hunk.

Had a sort of a doubt on a topic related to suspension systems.
So want to clear it here & now if possible. Since everyone comparing & talking about shock absorbers.
Does very little or no feedback from the shocks a bad thing ?
Im talking about this topic taking into account only the people who actually feel & hear their bike & not just use it as a means of transport.
P.S : I'm assuming feedback & jerk felt in your back & hands/neck to be very closely linked.
I'll be forever learning about this vast field of automobiles so feel free to correct me here.

Hi People,

I have been following xbhp since many months, applied few days ago & got approved just now. Read about tappet settings, de-carbonizing, timing, tuning and what not.

my big thanks & respect to Sibun, you are lifeline for all Xtreme/hunk/unicorn owners

Sibunji, I request your expertise in solving issue with my bike which is giving me sleepless nights

I have a second hand CBZ Xtreme 2009 model, (I love CBZ Xtreme a lot) and I always serviced it myself. But since a month ago I read tappet setting procedure on this forum, decided to do it.

Opened head cover, I set piston to TDC with 'T' mark, but the cam sprocket wheel was not aligned to head surface, its marking was not parallel, (my guess is previous owner mech messed it up & advanced the cam sprocket) So I manually adjusted the sprocket & chain to factory level (lines parallel to head surface at TDC, dot facing exhaust side) and then carried out a proper tappet setting procedure.

From then all my trouble started: Bike makes "kirr kirr" sound from inside the head, when engine hot. So I thought maybe due to advanced cam, rockers and all timing related items may be worn out/damaged.

So I bought new camshaft, rockers, timing chain, sprocket, chain guides, tensioner, and also new valves (with head work: lapping & compression test, new valve guides, from a reliable shop) & new oil pump. I properly installed all these myself painfully for 7 full day-nights.

But my problem of uneven "kirr kirr" sound isnt vanishing, I tried even more: changed ignition coil, spark plug & cap, checked all electric connections, recheck all installed components, checked oil flow to head, checked valve settings once again, cleaned carb, changed engine oil to brands/grades/quantity, did everything A-Z but Still no result, this left me deeply disappointed. I also heard from from crank case there is no noise from that area. Noise is only audible from head area.

I went to few mechs, they said crank bearing, piston rod, engine rebuild etc, but I am not satisfied with their answers. Also from this thread I read "ashwin.terminator" was facing almost same problems as mine in his Hunk engine, but replacing oil pump solved it for him. But not for me

Please help me out Sibun-ji! I will perform to all follow-ups u ask me to do.


Thanks a lot!

Feedback is both good and bad . Here's why ,
A John Doe is driving X bike which has monocross suspension , tuned for city rides. Obviously if he takes it to track , he wont be able to attack corners with higher speed , as spring rate and damping ratio of suspension was tuned to city road which has high undulations and keeps rider planted over bumps .

Same guy buys bike Y which has track tuned suspension , less damping ratio and low spring rate , drives in city and feels every bump going up his spine... In city drives it wont serve any purpose because one needs comfort in his daily commute hence he bought a bike that caters to his needs.

Anyone? Please do help.

Is noise continuous or in regular intervals ?
Continuous means its one of the bearings . Cam shaft one perhaps .
Regular interval noise means we need to dig deeper on what it can be .
