Sir your help needed.

Re: Karizma/Karizma R Ownership Experience

Hi all, i want to share my recent DIY on my karizma, I've replaced the entire carburetor assembly because of some irrepairable issues with the original one.

Here is the pic of new carburetor assembly-hero genuine which costed Rs.5890 and new choke cable @ Rs.90. I bought these from Parshwa Motors (Hero parts distributor) which is in J.C road.


The reason behind replacing carburetor is that the slide was not seating in properly in the carb slide cylinder. Cylinder had uneven surface wear and because of which the needle broke apart from its top ring.


I tried to replace it with new slide set (includes diaphragm and needle) but the new needle also gave up. See the pics below:



Since the problem is with the carb cylinder, the entire assembly had to be replaced. The engine is running better after replacing the carburetor.


I have a peculiar problem with my bike ever since I bought it 2 years back. It was there with the old carb and still exists with the new carb.

The engine runs smooth and pulls neatly sometimes(once in a while) and sometimes (most of the time) it is rough and feels like not enough fuel is supplied to engine.

The bike has run for 48000 kms running on 20W 40 grade engine oil and I am using NGK G-power spark plug and the AFR screw is at 3.5 turns.

Looking at the spark plug, i can see a dry black soot deposit on it. The deposit says that its running rich but the performance is not up to the mark and bike struggles to rev up.

I suspect that the spark plug is not getting enough ignition voltage because of which the fuel is not burning completely. Has anyone faced this kind of a problem?.
Is it because of 1) Faulty Ignition Coil (or)
2) Faulty Spark plug cable (or)
3) Faulty CDI. (Or)
4) Compression loss

I request the seniors to please advice on this issue.

Just get a regular 4700uf 50v capacitor, available for around 50/-

Procedure is more or less like this;

DIY: Motorcycle Battery Eliminator

Re: Karizma/Karizma R Ownership Experience

Confused[emoji849][emoji849] .The reflector is already dull .

Re: Karizma/Karizma R Ownership Experience

Damage to reflector is negligible considering the benefits you get out of higher watt bulb. Simply plonk in 55/60w halogen n ride with peace.

Battery will not die, don't worry.

Re: Karizma/Karizma R Ownership Experience

Can you specify the specs of capacitor and how it should be done? Are you sure that there are no other legal ways to improve headlight?[emoji16]

Re: Karizma/Karizma R Ownership Experience

If it helps you could run a capacitor parallel to the battery, you should get a marginally better output with the stock 35W bulb.

It would be best to stick with a stock 35W bulb for obvious reasons.

Re: Karizma/Karizma R Ownership Experience

thank you so much! will go through all of them!

Re: Karizma/Karizma R Ownership Experience

Facing problems with 35w halogens now. First I thought that I should go for 60w halogen but then came to know that I can't use it for long time because it will burn the reflector. AFAIK the hid and led are illegal. Two wheelers with auxillary lights are also stopped by cops. 60w halogen is not an option for me because sometimes I've to ride my bike for long time in night. Is there any way that I can improve my headlight without being stopped by cops?

Re: Karizma/Karizma R Ownership Experience

Makes sense to go for the P220 carb which is 3k cheaper than the ZMA carb, also to note that UCAL consumables are cheaper.

As for TPS it would be best to short it to WOT, though you'll loose that low end feel the motorcycle won't knock under load at higher RPM's.

[MENTION=32286]psr[/MENTION] sir has provided detailed information regarding ZMA's TPS in this thread do run a search to find the same.

A consistent 30+ kmpl under all conditions is a decent figure for a quarter liter, IMHO.

Your pilot circuit is running lean(confirm with spark plug read) or your choke cable has snapped(if there's absolutely no effect on RPM when the choke is activated).

It is unlikely for the pilot circuit to run lean on a stock motorcycle so inspect for leaks using WD40 test, if all is fine then make sure that AFR is set right.

Bajaj's are ideally tuned lean and even then both my motorcycles die when the choke is activated after the motorcycle has covered a few km's after being idle overnight, AFR screw hasn't been touched since purchase.

Re: Karizma/Karizma R Ownership Experience

About compatibility I didn't see any socket where I could connect TPS cable.

Its been few hundred kms since I am on P220's carb. Acceleration is decent my friend who is on Karizma's carb says acceleration is nice.
Bike goes till 120kmph without much efforts. I am getting fuel economy of 30kmpl approx.

Re: Karizma/Karizma R Ownership Experience

it has its own tps see its compatibility.
how's the p220 carb ?

if u want join whatsapp group

Re: Karizma/Karizma R Ownership Experience

Hello guys,

I recently brought pre-owned 2009 Karizma R. And I am loving it!
When I brought it carburetor was in extremely bad shape and stock carburetor was not available in nearby dealerships so my mech suggested I could put P220's carb so I did!but I later found out TPS sensor is disconnected now.
Any adverse effects on engine/CDI if TPS cable is disconnected? Can I keep using P220's carb for few more days? (I have already paid 2.5k for that)

Thanks,
Umesh

Re: Karizma/Karizma R Ownership Experience

What lifter ? this engine doesn't employ a hydraulic lifter for the valves.
What you probably need is to get the valve clearances adjusted to spec and maybe have the cam chain & tensioner parts inspected/replaced if required.

Re: Karizma/Karizma R Ownership Experience

Mine doesnt go off when i turn on choke on a warm engine[emoji28]
