Re: Royal Enfield Classic 350 Owner's Review and Experiences

Hi Team,

another day and another doubt. I performed the first service of my Bull at 499 KMS and the engine oil was replaced. The second service is due on the 8th of March or 3000 KMS whichever comes earlier. As of today my Odo stands at 793 KM and I will definitely not be going anywhere near 3000 KM. My understanding is that the engine oil need not be changed as there will be a difference of 300 to 350 KMS betwen the first and second service. Need your inputs on the current situation. Hoping to hear from you soon.

Re: Royal Enfield Classic 350 Owner's Review and Experiences

No oil change in second service

It's not about how hard you get hit, it's about how hard you get hit and keep moving forward.

Re: Royal Enfield Classic 350 Owner's Review and Experiences

Hey Shravan forget about this oil change at second service. In-fact RE recommends oil change only after 6K km interval and top up at 3K. So that means you should get it topped up (now that too, only if required) now and then change at 6K and then top up at 9K and so on. Even if you want to play it really safe still you can keep the interval of oil change to 5000 kms. Changing at every 3K kms is waste of money

Re: Royal Enfield Classic 350 Owner's Review and Experiences

Hey Guys,

thanks for the update. I'am sure RE service will have something different to say. I will have it checked when I leave the bull for service in a couple of days. Will keep the team updated on this.

Re: Royal Enfield Classic 350 Owner's Review and Experiences

Spark plug burnt (black) - engine over heating and sputtering

Hello All,

Sorry for asking too many questions. New to motorcycling in the sense that I have never owned one earlier and am facing some problems and trying to understand the cause.

I got a 4 month old, 1300+ km driven RE 350 classic. It has been impossible to start the bike using kick start early in the morning (7am). Even with electric start I had to keep the half choke on for 2 min for the engine to stay running. After talking about this to the service centre, they said that will just require some tuning and to bring it for that. So 4 days back the tuning was done. The person cleaned the spark plug, probably adjusted its gap and also tuned the carb and idle setting. Rode around 12 kms to home and found the engine more responsive or say quick acceleration than earlier. The bike was then parked though I started it the next day, let it heat up and idle and recorded the engine sound as it was a bit different than earlier and posted it in the forum to get opinion of you all if the sound isn't right.

Well, yesterday at night started the bike again (the kick start still did not help) and had to give the full choke for nearly 3 min. Then as soon as left to idle the bike stopped after a min. Took me about 10 - 15 min to get the bike started and found engine to be way hotter than usual. I thought must be something temporarily and might go away after I ride for couple of kms. So got on and engaged the 1st gear and it just wouldn't pick up at the little throttle. Had to move the throttle to nearly half for the bike to be able to move and the engine started sputtering. I had read in some posts wherein people mentioned that they faced sputtering problem at low gear and rpm. So I rode a bit further, engaged 2nd gear and still no good sign. The engine was getting way too hot now. Well, I dropped my plan and brought the bike home after riding just 1 km.

Called the service centre today and explained the whole problem. A person was sent to take a look. He took out the spark plug and said that it has gone bad (it was all dark black at the gap and near it) and replaced it with a new one. He also moved the screw of fuel mixture, not sure in which direction and said all is fine now.

I rode it for about 1 km and I am not happy. The engine is still a little more hotter than it used to be earlier and their is a slight tik-tik kind of sound that wasn't there earlier.

Before I take it back to the service centre again, can somone tell me what could have gone wrong that made the spark plug turn black in 12kms and anything else that might be wrong with the engine. After reading many posts on the forum, I get a feeling that the fuel-air mixture setting is bad for my bike. I have no idea how to self tune it as there is no tachometer in the bike. What all things I should ask the service centre people to check?

Thanks

Re: Spark plug burnt (black) - engine over heating and sputtering

Hi Team,

Finally completed the 2nd service of my Bull at CVS motors. Did not change the oil but did a top up of the same. they did a general checkup of the vehicle. I was charged 165rs as service charges. Please find the breakup below. At present the ODO stands at 825 KMS. Need to take her for a long ride soon. Will be back with more updates later. Bye for now.

Re: Spark plug burnt (black) - engine over heating and sputtering


Well I would suggest you whatever is done already but let's make it step wise. By the way, no way spark plug would go kaput for just 1300 kms run bike.

1. Fist please get the air filter cleaned thoroughly and also check for any leakage in the hose which connects the air filter to the carb.
2. Get the spark plug cleaned again, gap adjusted well and if possible even get the secondary spark plug cleaned.
3. Get the accelerator wire free play adjusted properly
4. Get the clutch wire adjusted properly (very important)
5. Please change the mechanic and get the carburetor tuned properly from a different mechanic. If required then get the carb cleaned as well.
Once he tunes , ride it there for 3-4 kms, feel the throttle response etc and if required get it tuned again then and there.
6. Get the TPS cable adjusted as per the manual/how it should be.


Please follow this 6 steps but with care and detail and all at the same time, and then let us know if the issue still remains.

Is the bike on stock silencer or changed?

I am waiting for a response from RE on the fiasco that their mechanic has created. I have got to know of a good mechanic from a friend but the bike has to be in the condition first to go that long.

This all started after the mechanic adjusted the spark plug, changed a fuse and tuned the carb so I am very sure that once the settings of the 3 are restored to original status, the problem will go away.

The bike is on stock silencer and no modification has been carried out except getting a petrol lock.

Re: Spark plug burnt (black) - engine over heating and sputtering

Your are welcome.

OK I added few more points please read them again. Please get rid of this mechanic. You can go to mehboob garage at Nandi Durga road, they are relatively better and they do a good work. It's an ASC. Let me know if you need any help.

Re: Spark plug burnt (black) - engine over heating and sputtering

That's the one even my friend recommended. It is about 12kms from my place but I have high doubts that the bike will run for that distance. Will surely go there once it gets into a little better running condition.

Sure won't let those two mechanics touch my bike ever again.

I have a feeling that the carb tuning has gone bad. I read up some articles on xbhp and other places on how to tune the carb but that requires a tachometer which I do not have else would have tried to get my hands dirty

Thanks again! Cheers!

Re: Spark plug burnt (black) - engine over heating and sputtering

You can tune it yourself without the help of tacho also. In xbhp only one some other thread I had given the detailed procedure how to do it.

Re: Spark plug burnt (black) - engine over heating and sputtering

Hey [MENTION=63513]gyan_recl350[/MENTION] ,

Could you let me know if I should ask for a specific person once I go to Mehboob's garage or just hand the bike to them and trust that all their mechanics are good?

From your profile I got to know that you also have a 350 classic hence these questions:

How hot does your engine get after riding for more than 5km in normal city traffic during the day? Are you able to touch the fins for a sec or not? The other day I had come after riding about 10kms at 7am and the engine was so hot that when I placed a paper on the start of the exhaust pipe it almost burnt. Got no gun to measure the temp.

Is the screw that is to the left of the idle screw the fuel screw or air screw? Could you send me a pic of your carb to see the position of each screw? Another mechanic came from RE service centre and he spent about 5 min adjusting the screws properly. I am yet to ride the bike for a distance after that. I just want to compare as the screw settings should be the same for all 350s since it is the same engine (assuming). That screw, when all was good with the bike, was about 2 turns in the casing.




After the 3rd carb tune-up the screw is about 1 turn out of the casing (as in the pic below)



Thanks

Re: Spark plug burnt (black) - engine over heating and sputtering

OK. You can better get in touch with Mehboob or his son Nawaz. They are good.

This is absolutely abnormal. Your engine is heating way too much. After some 15 kms or riding I can touch the fins for a second or two (may be more as did not test it thoroughly ) without getting my fingers burnt.

OK. So below is the image which tells which is what. The brass screw which can be turned using a screw driver is fuel screw and it meters fuel and not air. Also the carburetor is UCAL BS29 CV carb which is same in all 350cc UCE Bullets. So the carburetor in my bike and yours is same until and unless not changed. Also 2 turns is fine but still slightly, a bit slightly lean mixture I think. And screw settings depends upon many other factors like, which exhaust, which carburetor, size of jets, type of air filter etc. So it cannot be universally declared but I guess your bike is running very lean.

See the below image:






Now 1 turn out from the closed position is way too lean and might be one of the culprits for heating the engine.

Let me know if you need any sort of help.

Re: Spark plug burnt (black) - engine over heating and sputtering

Hello,

I took my bike to Mehboob Garage and Nawaz said that tuning is required. He adjusted the AFR, idling, clutch wire, and spark plug. Here is the sound of the engine after riding 30kms from the garage, Vocaroo | Voice message. After 40 sec the phone mic was always near the engine. At around 1:10, is the sound of the engine when the idling screw was turned a little to slow the engine which I thought is running fast, though have returned it to the position set at the garage. There is no knocking sound, I am not sure of how a tappet sound should be.

Either it is just in my mind or something is still wrong as I do not find it as it was earlier. I will go to a pollution check centre some day to get the oxygen & CO figures.
