Re: Karizma/Karizma R

1200 odd is the perfect price for the pair.

Re: Karizma/Karizma R

Please STOP if you haven't placed the order already!!!
Vicky dot in is fraud and is de-listed!

You may never receive your item/reimbursement!

Re: Karizma/Karizma R

Damn let me see if i can reverse this.

Re: Karizma/Karizma R

Trying their customer care no one picks up. Reviews on the internet suggest late shipments sometimes. Hoping for the best. Will send them an email too.

In the meantime, i tried out the G Power NGK DPR8EGP-9 spark plug today. The bike seemed more harsh somehow and was not pulling well. When i took out the plug, it was bone white. Does this plug make the bike run leaner? Do you need to change AFR settings while using this plug. I am currently on 3.5 turns of the AFR screw.

Switched back to the stock NGK DPR8EA-9 plug and everything was smooth again. Plug color also seems much better and the bike pulls nicely as before.
@psr, @Divya Sharan, @acs1207, @shriramefunds, others - any pointers that i can use thanks.

Re: Karizma/Karizma R

[MENTION=11326]The Pain[/MENTION] , I've been using G-Power plug for some years on my bike and felt only positive. I'm not able to think of anything that could affect your bike's initials. Well, that reminded me to buy G-Power plug for me bike as its due.

Re: Karizma/Karizma R

Hmm.. ok will try again tomorrow with another G power plug. I picked up two. Whats ur AFR screw setting at? Thanks

Re: Karizma/Karizma R

Are you sure that the ones you bought are original ones ? And why did you buy 2 ?

Re: Karizma/Karizma R

Yeah they are original. I normally always buy 2 of all the small stuff. Saves me the headache of looking for one again in the future if needed.

Re: Karizma/Karizma R

Check if you have properly tightened the new plugs. There is a crush ring and when you tighten it, it should become flat. Correct way to install a new plug is to tighten it initially to 1/4 turn and then loosen it and retighten it to max 1/2 turn (it may not be exactly 1/2 turn, but you should not overtighten it).

Re: Karizma/Karizma R

Thanks. This probably could be it. Will try again tomorrow.

Other than the possible mileage increase. Does the bike feel any different powerwise with the G Power plugs installed vs the stock ones.

Thanks.

Re: Karizma/Karizma R

@The Pain , I run with 3.5 turns AFR (last known). May be you'll need to check the plug once again, the GPower won't require to alter the AFR atleast in this case. You might want to do a run with 3.5 turns for a 50 odd kms and do a check on the plug color.

Re: Karizma/Karizma R

That was my thought too - that the crush gasket is not flattened. Another thing could be that the plug has a larger gap between the center and ground electrodes. It's 0.9mm for the NGK G Power and one can reduce the gap by 0.1 provided the plug isn't behaving properly.

Bike will 'feel' smoother, increased response from engine and as you mentioned, definite mileage increments.
Please do NOT over tighten the spark plug. Tighten it as far as it goes without resistance, and then a quarter of a turn should nicely seal it. This is after the crush gasket is depressed, of course.

Help needed for karimza r handling.

model: karizma r
modelL april 2011
kms done: 28,0000

The bike has been reliable and rock solid. but for the past 10 days, i'm facing a wierd problem in my bike.

My bike wobbles suddenly and wobble disappears suddenly. when the bike is moving, front wheel starts to wobble and the front wheel and handle bar get stiff suddenly as if the wheel has got punctured. then i apply the front brakes and everything is back to normal. this issue comes all of sudden and disappears and the bike is running fine again.

a local mechanic guy said everything is fine. most of the mechanics are not able to diagnose the issue properly as it doesn't appear regularly.

i tried 2 hmc service centre and they were not able to diagnose the issue and one on the basis of my explanation they are asking me to change the entire forks, handle bar and t cone. but the bike handles and corners well. there is no issue in handling. there is no shakes or wobble at 120. but the wobble comes up and goes once in a blue moon that too only around speeds of 60-80.

the bike had a minor fall down and there is a small bend in handle bar. but the accident happened a long time ago. after that i have done many trips. i have changed chain sprockets, oil seal for the front right side fork as oil was leaking, spark plug exactely at 23,000km. i have done many long trips after that. this issue has surfaced only a few fays back.

experts pls help. can you guys suggest me a good mechanic in chennai?

Re: Karizma/Karizma R

Thanks Bud. Will Check.
