Re: Jawa & 42 Ownership Experience





Omg! That engine exhaust area is now an eyesore! They could have used a similar chrome cover like in BS4 models.

Re: Jawa & 42 Ownership Experience

Chalo, they've added the Chrome cover.

Re: Jawa & 42 Ownership Experience

Asking on behalf of my brother :

He is planning to buy Jawa 42. There are a few questions to consider before buying, I am them posting here :

What is the regular maintenance cost of this bike ?

What about the part availability at service centers?

What is the ideal cruising speed ? He needs a bike with relaxed and vibration free cruising of around 100-110 kmph.

Is the stock headlight usable @80 kmph at nights?

Any major niggles?


Thanks.

Re: Jawa & 42 Ownership Experience

Thr regular maintenance cost is like 1.7 to 2k for me for the first 2 servicings.
I have bought the bike in Secunderabad, the parts are available there, so I don't see that would be a problem. It's better if you find out any local bikers for the same.
The cruising speed suitable is 80 to 100 maybe, I have been sensing vibrations lately.
The stock headlight is good enough at nights.

Re: Jawa & 42 Ownership Experience

And it has got ground clearance issues, I suggest your brother to take the bike for a test ride.

The seat is too short and hard for longer drives.

Re: Jawa & 42 Ownership Experience

My Jawa 42 is not starting. It was in rain for 4 days. What are chances of battery issue, water in petrol tank or in fuel injector and fuel pump? . Can we diagnose differently the issues related to battery and water mixing up.? Open circuit voltage of battery is 12V.Please reply.

Re: Jawa & 42 Ownership Experience

Does the fuel pump prime when you turn on the key, if yes, then -

1) remove the fuel cap, wait for 10secs and relock - this should solve air locking in the tank
2) check the spark plug connection, if possible disconnect and reconnect
3) does the voltage in battery drop below 11 volts when you thumb the starter, then recharge your battery (happened with my D390 due to non-usage during lockdown - recharged the battery and the bike came back to life)
4) remove the fuel pipe connected to the engine, turn on the bike and check if there is fuel flow, make sure you put the fuel pipe in a empty bottle, so later on you can put back the fuel into the fuel tank. Also you can observe the fuel in bottle to determine presence of water. If you do, then empty the tank and fill fresh fuel.

If the bike doesn’t start after doing all of the above then tow to the nearest service centre.

All the best!

The fuel pump, sparkplug , fuel pipe etc are not easily accessible. The battery Voltage comes to 10.5 while starting. Fuel cap trial was done as it was known to me. Thanks for the reply.

Re: Jawa & 42 Ownership Experience

Thanks for the reply.
The battery is changed with a new one, still the JAWA 42 is not starting. Where is the spark plug located. How to remove the fuel pipe connected to engine, to remove all petrol from tank, or fuel pump. How to identify if fuel pump is working. Please anyone reply. If anyone have mobile number of Mumbai regional manager, kindly share

Spark plug is located on the engine head / below the tank. I think you’ll need to remove the tank to access it. If you aren’t sure of how to do it, please tow the bike to the closest service centre to fix all the issues in one go.

Before you decide to tow, check the fuse box for a blown fuse and replace it.

All the best!!

Re: Jawa & 42 Ownership Experience

Check for water in the tank since it was in rain. Take a long pipe and push other end as much as you can in the tank. Basically you need to ensure the pipe end is at the extreme corner of the tank and water being denser will be at the bottom, at the lowest point of the tank. This is easy in carb engines since you can just drain the float and check.
Siphon some fuel out to a transparent bottle (about 1/2 litte should be enough) and check for water at the bottom of the bottle ensuring you keep it undisturbed for some time.
Also, check the fuses which might have blown due to short circuit due to water. Check for any broken / bitten wires which the furry friends might have chewed too.
Once I had a rented Thunderbird 500 which refused to start since the FI fuse had blown, no amount of kick starting or pushing would start it since the fuel pump wouldn't prime. So it could be something as simple too
I hope you are not using the throttle while trying to start since FI engines don't start when throttle is open unless engine is flooded with fuel.
Let us know how this goes. Do keep your bike away from rain otherwise it could begin rusting badly. My 13 yr old Apache has no rust anywhere except for the exhaust due to this simple reason. Put on a cover if no covered parking available.

Re: Jawa & 42 Ownership Experience

You should try Perak too. It has great road presence. In my opinion 42 and classic are going to take a back seat now that Perak is out.

Read this Jawa Perak review, it will sure be useful: https://footloosedev.com/jawa-perak/

Re: Jawa & 42 Ownership Experience

We went on a short weekend spin and spoke with 2 Jawa 42 owners. I made a small video about it. Hope you all like it and show some love.<br>
<br>
in short - Perfect bike for sunday morning rides. Thats about it.

Re: Jawa &amp; 42 Ownership Experience

I keep seeing the reviews from the professional youtube channels and all of them mention that Jawa 42 is good for short rides.
Does it mean that its not very comfortable for long rides? I understand people complaining about the seat, but that can be easily modified.
But my question revolves around the sitting posture and leg positions and it might not be very comfy for long tourings.

Re: Jawa &amp; 42 Ownership Experience

Do any of you have issues with the engine shutting of on it's own for no apparent reason?

I have returned the bike to SVC about 10 times by now and they can't seem to solve it.
