Thanks for the prompt reply buddy!

I checked and found that it leans towards one of the side; but it's not tight for sure.

I'm not sure about 'cone'. Could you please shed some more light on this please?

If you have had a fall - get the bike checked for a fork Bend.

You will experience wobbling even if there is a misalignment of the wheels. Get the alignment checked as well.

Another thing that might be a potential issue is fork oil.

Sandeep, much appreciated for your thoughts! But I didn't had any fall, fortunately!

But yeah, I hit a pothole during a highspeed!! That must be the culprit I guess. BTW, if it's a wheel alignment issue, then the problem should start as soon as I start riding my bike. But that's not the case here. As I mentioned before, it starts once I hit any bump/pothole. Could be an issue with the fork oil though! I will get it checked!! Thanks a ton buddy!

Naaaaaahh!! I checked it the first thing! Disc is intact and fitted perfectly!

But totally agree, it could be one of the reasons; but in my case its not! Thanks dudh!!

Lately I've been facing problems with the front tyre of my Karizma R! It wobbles after few kms of riding, especially after applying the front disk, or when the bike faces any bump or pothole. I've got the 'wheel-through' done and they say it's perfectly ok. But I'm sure the problem persists.

Have you been through a puncture recently? If yes, then check the front tyre tube, whether it was properly set in the tyre without any foldings.

I experienced this and the tube was the culprit!

Been there, done that!! This was the first thing that I checked dude!!

But to no avail!! This problem is driving me crazy!!!!!

I even tried changing the rear tyre and tube to ensure that the rear rubber is working fine!!

Try this. It may not be the solution, but it is worth the try, especially if you've done more than 10k kms on the bike.

Hmmmm!! Checking the Tcone was already on my list; but the link really helps!! Quite exhaustive information there.. Thanks buddy!!

I'll definitely get the bearings replaced without giving a second thought + folks will be oiled.

Again, Danks!!

BTW, a quick question for you Nirvan!! Can you please tell me where exactly the 'cone' is located? Any screenshot would definitely help!

This link will help you understand where the cones are. Cones are part of the steering bearing assembly; there are two sets, one directly under the handle and the other set at the lower T that grips the front shocks.

Head oil leak problem.

Guys, My ZMA has run a little over 9k kms and is due for its 5th service. I have observed oil leaking from the front portion of the engine head since first service and reported each time during service. They paste the joints with some kind of grey sealant glue. After the service the oil does not leak for 2 - 3 weeks and then it reoccurs. Does this indicate a serious manufacturing defect or is it a simple issue of bad sealing?
What could be the reasons for such an oil leak?
I used to have the same issue with my 2003 Fiero F2 (after 50k kms) and never got fixed by TVS service centers, later the guys at castrol bike zone solved the issue once for all. It did cost me about 1500 bucks, which included valve seating work and some machining.
Is such an engine work needed for my ZMA? I do not have any performance issues with my bike. Please help.

Sounds like a faulty head gasket and/or sealant.

The Service Center is probably doing a patch job every time you complain, which leads to the recurrence. Start by having it dismantled, cleaned and reassembled, with new gaskets and sealant.

If this doesn't work, then some machining may become necessary - which means a replacement if your bike is still in warranty. Try to have this done in the Service Center with you present, to verify that they are actually doing the work they said they would.

**siva1001** · 08-11-2009, 11:09 AM

Thanks Nirvan.
I would have to claim my warranty for this repair job. I have heard that Srinivasa motors in Chennai is one of the best, but such a poor A.S.S. is getting on my nerves.

I have to stick to them only because of the warranty.
Also these guys do not allow the customers inside the service station.

Folks from Chennai, Can you let me know any HH service station which allows the customer to see his bike being serviced?

yes they use liquid silicon based sealents
I used to have same problem with my zma,and even after trying all kinds of sealents,there was no relief
on closer examination manufacturing defect was found in the clearances between metal parts,and the part above the head was machined,and then problem was resolved.
you may want to get this checked.
