Re: Stratring Trouble: Nearly frustrated

Oil burning would give white smoke but black points to rich / improper combustion.

This is getting complicated , Dont replace anything until and unless you are sure its completely busted. Engine jobs are like a gamble.

Some rebored cylinders work better than stock ones, while 60% of them are shoddy work. Where do you reside btw ?

For peace of mind get new block , but i dont think block has worn out or is damaged.

Re: Stratring Trouble: Nearly frustrated

my starting trouble went from bad to worse now. Even push start was hard yesterday. Today, I gave it to Honda SVC mentioning to check the compression. Also, the engine oil is getting burnt up too fast. Around 1000 kms of last 2 oil changes, the oil level went low. Also, there was a black smoke exhaust twice in last 2 weeks. Mentioned that too to them.

The svc guy who took it told that for the oil issue and black smoke in the exhaust, the engine also needs to be checked. I would get a call in 1 or 2 days from them. I am not sure if something is worn out but there is definitely something that is not correct.

My question is when does an engine needs to be worked upon, and if it is to be done, will it behave the same way as it was earlier? I hear from a lot of people that a rebored/overhauled engine will not be the same once it was

Please advice

Edit: I just clocked 102+ yesterday n without any sound/issues. Didn't feel any big power drop or feel. Will a bad engine could have handled it?

Re: Stratring Trouble: Nearly frustrated

It maybe a battery related issue , but seems unlikely , if you can cold start bike in morning using battery then it should be fine. Change spark plug if its 10k kms old. Also just a thought , get compression checked by svc, Unicorns are notorious for compression leakage.

No idea about electricals bud, i like to keep bike bone stock with very minimal changes to electric circuitry.

Re: Stratring Trouble: Nearly frustrated

Thanks for your help. I have no problems while riding my Dazzler. Is using choke the only option to start my bike daily when the engine gets cold? I never had this issue a year ago before except sometime when it was idle for few days.

And even using choke it doesn't start on its own. I need to accelerate my bike at the right time when pressing the starter. Or else it wont. Is that ok or should I need to fix something?

Also, for the last two days, even if the engine is at its running temp(bike was idle just for 15 mins after 30 mins of travel), I need to use choke and rev a little to start the bike. And it works fine. When I just press the starter(with or without choke), I just hear the rattling sound the bike trying to start. But it fails. I need to pull choke and rev a little for it to start.

Could this be a problem with spark plug or should the battery needs to be charged(I see a very little drop in Neutral indicator when I press the starter, but I think the battery has enough charge to start the bike) or is this because of something else?

FYI, I changed my bike from AC/DC setup to full DC a long time back and the headlight is running on direct battery current. I was using HID for sometime, but the bulb fails after few months. So I was using a normal bulb with DC current.
Yesterday, I changed to LED light(M6) and it's really awesome. It is very gentle to the battery and uses very low power.

Re: Stratring Trouble: Nearly frustrated

When turning on cold engine , use choke and kick start it . Then turn off choke after 5-6 secs and let it idle on its own . After a minute or so start riding. My unicorn shows same characteristics but xtreme doesnt , it never requires choke to start , just touch the starter and it starts on half click and idles like a gatling gun

Re: Stratring Trouble: Nearly frustrated

thanks mate.. got it..

ok I finally did it. Got the engine to heat up a little before I started tuning. I achieved max RPM at 3 and the AFR screw is now somewhere around 1.7-1.8. After completing, I have set my idle RPM at 1.2.

And now I see most of my problems disappear. I used to rev the engine often not to let it shut down when idling. Now, I don't need to bother about it. It is back to normal again. I have one doubt though.. When turning on the engine when it is cold, it still needs a little time to get up running properly or else it switches off if I try to rev.

Do you think I should still tune it for optimal, like (1.9~2) as you suggested, or just increase my idle RPM to 1.5.

Before I started all this, I calculated the turns and it was somewhere from 2.5~3.

Re: Stratring Trouble: Nearly frustrated

Screw with orange circle is the afr screw

Re: Stratring Trouble: Nearly frustrated

ok, I am a little confused here. Can you tell me if I am seeing it correctly. I have marked the brass pipe and a screw that I am supposed to adjust for AFR setting in the image(orange and green colored circle).

Can you tell me if am correct or is it some other screw and pipe that I should be looking upon.

Re: Airfilter Change - Honda Dazzler

Knowing the kind of workloads that the ASC works under, and the hilariously low servicing costs specified by OEMs that they have to adhere to,
it is very likely that he just mentioned "Air filter cleaning" so that he could add on labour charges for that.

Basically, you are less likely to fight against the amount of the total bill if he rattles off a long list of stuff that he has done (whether or not he has actually done it)

The ASC staff have enough training to know not to clean a viscous filter.

Re: Stratring Trouble: Nearly frustrated


My FE a year ago was nearly 49-50 when I dont go over 50KMPH(did it deliberately to check max mileage) and the least FE was 46 when I start maxing out(staying 70+ and touching 90-100 often).

But in this last year, I got this FE reduced drastically and I get only 42-44 with this starting trouble worsened. I was using Shell Full Synthetic oil till now and moved to semi synthetic to check if that could help me in starting trouble.

sure buddy, will try it this weekend and check if this improves the performance.


BTW, my choke is not working. Had clutch plate replaced two weeks before and I think the mechanic didn't finish it properly. Even the clutch doesn't work sometimes when the bike is off. Going to take it to him this weekend. (I completely damaged my clutch revving 7+ during the flood in Chennai last month).

Re: Stratring Trouble: Nearly frustrated

600 rpm difference clearly shows lean mix , next time while having hiccups engage/pull in choke and see if performance improves. It should.

Re: Stratring Trouble: Nearly frustrated

The cold RPM is a little below 1(0.6~0.8) and in a minute it reaches one. The hot RPM is nearly at 1.5 when the engine is completely smooth except the occasional hiccups I think because of less fuel which I have no idea why it happens during the travel.

Re: Stratring Trouble: Nearly frustrated

Before doing this please tell me your cold and hot RPM

@plasmabhai, [MENTION=57344]RohIIT[/MENTION] your help is needed for the above query by crazydriver!

Stratring Trouble: Nearly frustrated

Hi,
I have been using my dazzler for the last 5 years and for the last 1 year I am having trouble in starting up my bike after long idle(mostly in the morning and late evening when leaving from office).

When I press the self-start, the bike starts in a second but I need to leave the bike to run in idle without giving any acceleration. If I give even a little acceleration, the bike engine ceases as if there in no petrol to burn. I can feel that the engine is struggling to run and takes 2-3 minutes before it feels smooth.

Can anybody help me in telling what could be the reason how can it be fixed as it is making me really frustrated. Everyday when I start my bike, I just stare at my speedometer controlling myself not to pull the accelerator.

And I have another issue but that doesn't occur often. While on the run, the bike suddenly struggles to accelerate as if it is time to pull the reserve knob, but if I rev it continuously, it comes back to normal. If I leave it without revving, it switches off and doesnt start. I just need to walk my bike for sometime and then voila!!! the bike starts as if there is no problem.

I would kindly appreciate anyone giving me slightest clue on why I am getting this
1) Starting trouble, should leave the engine to heat up and should not accelerate till then
2) Hiccups during journey as if the petrol is gonna end, but recovers automatically.


Note:## I have cleaned the carburetor many times and nearly emptied my tank and cleaned it with a cloth suspecting water could be there inside but still the issue persists. Also have changed the spark plug, the adaptor too..
