Re: Airfuel tune for an aftermarket airfilter on zma!

Hi psr!

Thank you for your valuable inputs as always.

For the rear shocks issue I had, I replaced the old ones with ZMR's gas filled ones (Thank you Lohit Kotapati for all the details!).
As usual the ASC didn't have them in stock. TheSparesCompany.in provided an excellent service and since I stay in the same city, they delivered it the same day.
While replacing, I kept the old and new side by side and observed that the old one had some deformation (bend).


I am going keep a check for a month and then will arrive at a conclusion on the comfort of these gas-filled ones.
I am going certainly bump up the stiffness during touring with the saddle bag.

On swing arm lubrication, had got it done at 30k km. The bushes had broken inside and the ASC had a tough time removing the old ones.

Also, I would take this opportunity to know more about you. Many of us have seen your valuable replies in Karizma as well as CBR group.
If you can let us know what bikes you currently own (and had own before) and what is your profession!

Thank you once again!

Re: Airfuel tune for an aftermarket airfilter on zma!

The stock air filter is the best..K&N will allow more air along with more dust which will kill your Carburetor , and engine. Tuning a CV carburetor is an art and not many will be able to get the correct AFR ratio through the RPM range...so stay away from it...

----consecutive posts auto-merged-----

The shock setting will depend on the load at the rear..If you have more than 60 Kgs of load at rear, apart from rider, then set it one notch higher from lowest setting..otherwise the present setting will give you the best cushioned ride. Regarding the back pain , check your swing arm Lubrication..if it becomes sticky the up and down movement of the rear wheel will be affected.Get the swing arm opened and inspected for rusting and lubrication..at close to 37 K Kms I am sure the lubrication had dried, and needs to be greased liberally.
Good luck

Re: Karizma/Karizma R Ownership Experience

Hi Guys, need your expert opinion on rear shocks:

My Karizma R has done close to 37,000 km out which approx 18,000 km has come via long-distance touring with ViaTerra saddle bag and saddle stay at the rear.


From last few weeks, I am experiencing severe lower back pain during my 20 km one side office commute. I feel each and every pothole on the road.
I checked the shock settings (see images below) and I believe that it is at the softest setting (They have been on this setting since day 1). Not sure what my options are besides replacing them.




Also, I believe going forward I will have to make the shocks firmer when I travel with saddle bag during long tours. Is my understanding correct?

Airfuel tune for an aftermarket airfilter on zma!

Hello there xbhpians, I'm planning on replacing the stock airfilter on my ZMA to an after market free flow airfilter (BMC or K and N )! I've heard that tuning the carb is a must if you change your airfilter to free flow airfilters! I'm kinda confused, as of now my ZMA is running on 3.5 rotations anti clockwise from full tight! Any suggestions on the tune ratio after fitting in the free flow's? I'd be happy to accept suggestions on airfilters too!
Thank you [emoji5]

[MENTION=37035]ashwinprakas[/MENTION] thanks man. Please let me know if you hear anything from your friend about this.☺

Re: Karizma/Karizma R Ownership Experience

Any suggestions
Can it be timing chain tensioner?

Re: Karizma/Karizma R Ownership Experience

Try CBZ forks, not sure about which iteration but a friend went with a pair to raise the front by a few inches.

Re: Karizma/Karizma R Ownership Experience

Hey xbhpians, I need your advises and help here. I was thinking about increasing the height of front suspension. Can I increase the play of the forks? I would like to ride a machine with little more height in front.
Is there any way to do it? If yes, please let me know the details and cost.
Thanks in advance[emoji2]

Re: Karizma/Karizma R Ownership Experience

Then it can be the cam chain tensioner.

Re: Karizma/Karizma R Ownership Experience

It is only on idle,not much to notice when moving.

Re: Karizma/Karizma R Ownership Experience

My engine sound was exactly the same as yours. Mine was rectified by changing the cam chain tensioner. Does the sound lessen when the engine heats up?

Re: Karizma/Karizma R Ownership Experience

Psr sir bike is very smooth,minimal vibes
Is it possible for a bike to work in such a way,with the crank damaged?
Do you think it can be timing chain tensioner.

Re: Karizma/Karizma R Ownership Experience

How was your problem solved?
Did your engine gave same sound as mine?
Timing chain is 1.5 yrs old,only 8k done

Re: Karizma/Karizma R Ownership Experience

It can be a problem with cam chain tensioner, also check the valve too. I too had this problem earlier. Check with the timing once in 20k, this can prevent premature parts replacement.

Re: Karizma/Karizma R Ownership Experience

Without opening the engine , it is hard to tell , because the condition of associated parts must also be evaluated....
