Re: Cam Tensioner Noise?

I am just guessing, you might have burnt your clutch while running with tight brakes.

Re: Cam Tensioner Noise?

One stupid question
Are you sure you have replaced the OEM chain sprocket and haven't played with the gearing?

AX7 is semisynthetic and doesn't take much time to set in compared to oils like 300V. So if you have done >100kms after the oil change, it should work fine.

Sometimes the bike just feels sluggish as the sound and feel of engine changes after changing the oil,but it is actually not. Please try to ride it head to head with another Karizma and compare how much time it is taking to reach a specific RPM.

After changing to K&N filter , I was happily revving and feeling that I am going very fast . But only after riding head to head with a stock Zeema I found that my bike was actually taking more time to reach 8K RPM in each gear

Re: Cam Tensioner Noise?

With tight brakes would have done hardly 7-8kms. Not more than that for sure.

Oh I don't disturb the gearing because I don't know . May be I should check the chain slackness.

I haven't done even 25kms after oil change. Should I give a time and see? Amit, just that you know Ananth, we both are going to Madikeri side coming weekend. Reminded of our trip 4 years back.

So you haven't removed that K&N and P220 sprocket from your bike?

Re: Cam Tensioner Noise?

Before I can throw in my two cents, just a few questions from my side.

In all these 12,000 KMS have you performed the periodic valve clearance check and if adjusted your valves accordingly?
Have you checked your chain tensioner in all these KMS, have you checked for slack if any, adjusted accordingly?

Though this might be anything from worn out tensioner/tensioner pads and chain to loose tappets, the sound more or less resembles something to do with the head of the motorcycle. A worn tensioner and loose chain, though they produce some uneven slack noise, they won't produce such dramatic ticking and banging, at the least they retard or advance your timing, causing poor performance. My first suggestion would be to, just head to your local mechanic tighten/reload the tensioner and see if the sound subsides, or if you observe any improvement, if it does, then at least you can get your arms around the problem, if it still persists it "might" have to do with head, this is my gumption based from what I am hearing from the sound.

Re: Cam Tensioner Noise?

How does one tighten the tensioner?

Re: Cam Tensioner Noise?

As you know the tensioner is spring loaded and cannot be tightened, maybe I took it too mainstream so that folks would just understand. If those were removed and improperly installed or if they were mal-aligned wherein people might just use the screwdriver causing tensioner damage. Perhaps remove, reloading (tightening in a mechanic's term) is what the post really intended. Hope it's clear now

Re: Cam Tensioner Noise?


Thanks for replying bud. It apparently was the tensioner causing the issue. Got it replace this morning and it seems to be sorted out now. Costs about 450/- overall 530 with labor and taxes etc.

Havent done a valve check yet. I picked up the bike 2nd hand at around 10k kms. Whats the right period/kms schedule to check valves clearances on the Karizma?

Re: Cam Tensioner Noise?

So it was the tensioner indeed, great. If I remember correctly most of the bikes have their valve check during the running in, say around the 500 to 700 KMS and again around 5000 to 6000 and then at around 11000 to 12000 kays range. So I guess the Karizma shouldn't differ much. Mechanics use feeler gauges to check the gap between the rocker arm and the valve so that they are gapped to spec. A loose tappet produces this so called " tick tick tick tick" noise, even though it is present on all motorcycles, this is a tad amplified with things get a little loose. Considering the bike is pre-owned and you don't have the service record, it'd be wise to get it checked.

I guess you're in the right ballpark at 12000 kays, why not just opt in for a general clearance check, hardly a half an hour job.

Cheers!

Re: Cam Tensioner Noise?

Thanks bud. Will do. The bike has an excellent service history though. All reciepts/scheduled maintenance. purchase bill etc.

I had a very slight tappet sound too from the bike around 6 months ago which was sorted by the svc and hasn't surfaced yet

Re: Cam Tensioner Noise?

[MENTION=11326]The Pain[/MENTION], Mild tappet noise is not that all harmful as one think. There will be tappet noise heard even when the bike reaches optimum temperature or after you stop by after a long run. Lets not fidget too much with it. Hear words from this forum experts for your better understanding.


I CAME ACROSS SOMETHING NEW

Just like everyday we learn something, I got a chance to know new is that there is a difference in the rear wheel bearings for ZMA produced pre and post 2011. I recently had a chance to compare the parts catalog with the dealer and saw the difference. I'm not sure if you guys noticed the ID and OD differences, however, the hub and brake drum plate if noticed are slightly different. That actually gave me even more stronger belief that there is some change. Please ignore if you are already aware. Since I'm without mobile could not capture my observations.
I can get the bearing numbers shortly.

Re: Cam Tensioner Noise?

Thanks Sriram. I also own a d390 so am used to a lot of racket from the engine.. Ticking rattling etc.

The tappet sound on the karizma was pointed out to me by the svc mech himself which he sorted out during a routine service.

The valve clearance check is recommended for the KTM as well so I guess it's a good idea to check once in a while to ensure the clearances are within spec.

Guess whose back after a well deserved rest.

Re: Karizma/Karizma R

It's a well deserved comeback ! 😀

Re: Karizma/Karizma R

Indeed, new AF box and plumbing, new SAI and plumbing, valve stem oil seals replaced, all other leaking seals replaced, cone set replaced, front rotor and brake pad replaced, rear brake replaced, handle replaced, bar ends changed to plastic ones, new carburetter and plumbing, replaced all cables, replaced horn to stock, front fork springs replaced, front fork dust and oil seals along with oil replaced, new chain and sprocket kit. And many more.

Spares(some) cost around 10k, SVC bill(including some spares) around 8.5k, 1.7k Insurance. And it took over a year to get everything done, definitely worth it I'd say.

Re: Karizma/Karizma R

I'm sorry if I missed the back story of this bike but can u plz explain why so much work was done on it. What happened to it? Thanks
