Bajaj Dominar 400 Ownership Experience Thread

Re: Bajaj Dominar 400 Ownership Experience Thread

A month back I purchased dominar without abs as that is the only piece available to my near showroom... Well completed 430 kms and waiting for first service.
I observed that the rpm of engine remain constant even after leave the accelerator, and it take more time than other as I experienced in my previous pulsar 180.

It is normal or do I need to tell this to service center. Another thing I wanted to know weather it is possible to put abs on my domi or abs not come separately.

Just check what's your idle rpm reading (both hot and cold).

And I don't think adding ABS would be possible or at least cost effective.

Re: Bajaj Dominar 400 Ownership Experience Thread

It has only been 3 months and there is rust developing in between the gaps present in the engine
Is it normal and happening for anybody else or is it just my bike?
and will it be a problem of some sort in the future?

This is normal... This the engine block sealent.

Re: Bajaj Dominar 400 Ownership Experience Thread

Is it really important/needed to follow the 2000 km run-in as mentioned in the owner's manual? It is mentioned to ride at a particular speed till 1000 km and then increase a bit till 2000 km. But I have read in so many other forums that the run-in after 1000 km is not really necessary for new engines. Could anyone please give more details. Thanks.

Hey Arvind,
It's okay if you rev the engine after your first service. The reason why they mentioned 2000 kms is because the juices needs time to get settled properly in engine and other parts. If you follow the particular speeds, you follow the ideal RPM count for newly built engines.
Many people tend to follow the speed limits than RPM limits and hence it is mentioned in speed in the owner's manual. Trust me, it will help your engine perform better if you keep your bike in limit. Also, you will feel the smoothness of the engine
Hope this helps

Thanks for the quick answer. I have been riding the machine maintaining not more than 3000 RPM. Now I have completed 700 km (done the first service at 500 km). You know, it is too hard to ride the machine within the 3000 rpm range even though it is for the first 1000 km. Still I am following that for the long term affair with it. But, I am confused how all of a sudden from 1001 km we are able to increase the RPM, since the next service is only on 5000 km. So, wouldn't the engine oil still contains shaved off engine elements. So shouldn't we change the oil again at 2000 km (if we follow proper running in) before opening up the machine to its maximum?

Thanks

Hi

I would like to correct nishi here (no offence), but the running in is to bed or properly mate the piston rings with the cylinder wall , with the oil providing a lubricating barrier to prevent any major abrasion between these parts. Usually new cars dont have any such running in period since most are set at the factory itself, but motorcycles in India are built to a cost, and to be honest, the engines arent as refined as the cars we buy. Even hondas for that matter in India are recommended to be run in for a few hundred kilometers. The running in or break in might also help catch any engine anomalies early on so it can be addressed under warranty. An improperly mated ring and cylinder wall will consume lot more oil, and you can see white smoke from the exhaust for badly mated new engines.

The shiny nature of oil during first service is due to the 'shaving' of the mating surfaces, but they arent really visible directly, unless you hold it in light or at an angle. I believe manfacturers just continue to specify break in periods so a new user adapts to a new motorcycle or car gradually.

I personally dont want to take any risks with a new expensive automobile, so i follow manufacturer instructions to the full.

Yeah..!! This is the reason why every motorcycle have running in periods. And most people tend to follow speed instructions than RPM limits.
That's a good technical explanation though.

U can safely ride till 5k rpm by riding at 3k rpm you are not using all the gears and if u are riding at 3k rpm in top gear means you are lugging the engine which is as harmful as over revving during run in. The company has set a warning rpm at 5.5k which actually is 5.7k. This is a big block single and it is safe to keep in power band during the run in. 4.5k to 5k rpm is safe now since u are done with first service.

Re: Bajaj Dominar 400 Ownership Experience Thread

Hi guys, any contacts if a good mechanic in Pune who can install fog lamps in the dominar... I am looking for some one who is good and know what is he doing.

Re: Bajaj Dominar 400 Ownership Experience Thread

Today I found some oil stains above the oil filter (not sure it is leaking from oil filter seal)


When inspecting for any leakge in engine block, I dint find anything. But there is a screw thread with out a screw below the engine.



Please some one check ur dominar if it just got a screw thread or screw fastened..

Also please advise about the oil stain above oil filter. Thanks

Dont worry it is just a screw thread. There is no screw in it. Same in my dominar

Re: Bajaj Dominar 400 Ownership Experience Thread

[MENTION=92169]jagaddjag[/MENTION] yes as DJD said it is only the thread there is no screw and it is on both sides.

And for the oil marks yes it looks like there is some seepage from the filter o ring clean it and check and if it still exists then go to any mechanic he will apply some bonding agent to the o ring and this would stop.

Re: Bajaj Dominar 400 Ownership Experience Thread

My dominar has covered 240 kms and was bought on 11th Nov. the initial 70 kms were driven in city bumper to bumper traffic. And from 70 to 210 kms were covered on highway. I kept it around 4km rpm on highway at 6th gear with one or two attempt to touch 90kmph and then back to 70kmph.
The weird thing i noticed today morning is the level of coolant.
When i bought the bike it was exactly above mid level. But today morning its near minimum level mark.
Pics for reference. I understand that some coolant would flow into the pipes and radiator fins. But it feels it like it has dropped a lot.

This is taken when engine was cold and bike upright:


This is taken when engine was hot after riding 10 kms with bike upright:


And engine oil level window when engine was cold:


Engine oil level window when engine was hot:


there was no coolant seeping out below the bike. There were no stain marks or fresh coolant drops below the bike.
The thing that is bothering me is could the coolant be mixing with the engine oil? I will be taking bike for first service at around 450 kms though.
Also there are some moisture precipitation at internal wall of coolant chamber. Is that normal?

There was one case posted in DOC bengaluru group where the owner had troubles with the bike’s coolant getting mixed with oil and ASC had a hard time fixing it eventually causing a lot of turmoil for the owner. This is worrying me.

Re: Bajaj Dominar 400 Ownership Experience Thread

For a new bike, coolant top up is needed.
I had to get it done as well.
Bajaj is probably not making a note so we need to keep an eye.
it is normal and you dont need to worry.

Oil sump looks normal and you cant go by the book here.

+1.

New engine heats up more so coolant get consumed get a top up done when i have time it is still in safe zone. I rode with similar level till first service. After second service the level hasn't dropped.

One more thing the coolant also expand in hot weather so could be coz of weather getting cooler.
