Re: NS200 mileage problem & can't drive in traffic on low rpm

It is highly recommended that you test ride a bike extrnsively before buying, especially if you are buying a used bike. If the price is too good to be true, it is for a reason.

Riding without the coolant is just not about the mileage, it can have serious consequences like engine seizure.

Chain alingment/slack may be off, as it is a used bike. Checking with another bike can help here.

Could be an issue with the carburetor or air filter. Get them checked. Could also be some deep rooted issue but get these checked before going with other suspects.

It does. But if your mileage is less, it could be due to many other factors. Get all the things right before coming to mileage.

Not at all. Walking through traffic must be done in 1st gear or 2nd gear (only if the speed is above 20 kmph). Riding in high gear low speeds will damage the engine.

Worn out tyres may give a slightly higher mileage. But don't rejoice. It is a safety risk as it may cause poor braking and/or loss of grip and control. Get the tyres changed as soon as possible if they are worn out. Never skimp out on this.

You have more important issues to get sorted out before coming to this one. Get them done first.

I strongly recommend that you give the bike to a reputed SVC – one with staff who really know what they do; not the one where the guys just loosen and tighten rome random bolts without the slightest knowledge of what has to be done. Get it thoroughly inspected, checked and fixed. Don't hesitate to spend for repairs but also make sure they don't take you for a bounty hunt. Post the costs of repairs before getting them done. Fellow members will let you know if it is necessary and they are not extorting you.

Re: NS200 mileage problem & can't drive in traffic on low rpm

Very well said bro. I'd request OP to get it looked after by SVC and get the required repairs done. Then only you will enjoy your ride to the fullest.

Re: NS200 mileage problem & can't drive in traffic on low rpm

Hmm!
My chain was rubbing to something which I felt near foot pegs.
My coolant box was broken long ago before I purchased the bike.
Tires gone.
Engine making lot of sound.
Old engine oil.
Couldn't ride at low rpm.
I gave the bike and told them to try to make it like new. I am ready to pay. I went to office, came back, took the bike. They said they don't have coolant box, no need to change oil, rest are common in all NS.
I went to another service center for coolant box fitting, told them that chain is rubbing somewhere. He told chain is tight and loose at some spots. need to change chain sprocket. Will changing chain sprocket solve the rubbing problem?
Also I am a bit worried as 90% I am in traffic, and confused how to cope up with low mileage of 29 kmpl.

Re: NS200 mileage problem & can't drive in traffic on low rpm

Get the cooling system fixed first. Keep this as your top priority. I've ridden this bike and I know how much it heats up in slow traffic and signals. Without cooling system, it is unimaginable. Also the lack of cooling may cause engine damage.

Get the tyres replaced as soon as possible. The stock MRFs are good. Never go for Eurogrips... I repeat NEVER EVER. If you need to get some other better tyres, then post a query in the tyres thread.

The engine sound may be due to the lack of cooling and consequent damages or due to old oil or may be the way the bike is (when I first rodr this bike, I felt it noisy). Taking a ride in a properly maintained bike will let you know is something is wrong.

Get the engine oil changed along with the oil filters and stuff. It doesn't cost too much and an oil change never harms. [As long as you stick to a good company oil of the correct grade though] Old oil can also be the cause of engine noise.

See how many kms have been done with the chain sprocket set. Usually it must be replaced in ~25k kms (For a very well maintained chain sprocket set). A proper chain set must fix the rubbing issue in most of the cases. There will a rubber pad in the swingarm that prevents the chain from rubbing directly on the swingarm. Get it replaced.

Specify the exact RPM or RPM range which you mean by low RPM. Cannot comment anything without knowing that.

As I said earlier, there are more things to be worried about before coming to the mileage. Getting all the issues fixed may improve your mileage by 10-15%. Even with a perfect bike and sane riding you will get max.35kmpl in traffic, 35-40kmpl in city and 40-45kmpl in highways. This is a 200cc 23bhp bike. Keep it in mind before thinking of mileage.

Re: NS200 mileage problem & can't drive in traffic on low rpm

1) Cooling System - This is very critical part of the bike as it is not air cooled, the whole cooling of the bike is based on the liquid cooling. I can't stress enough, it'll lead to engine damage.

2) Tyre - These are the ones that are between the road and your bike. So, it is also very critical to grip and hence fuel efficiency and performance.

3) Regarding chain noise - from my personal experience from the first service of my P220 which was 2 weeks ago I'd say this: first check the chain marking on both sides, is it equally set? then check the chain tightness/slackness. Then clean and lube the chain. This would probably solve the problem if your chain or sprockets aren't worn out. If you see that the sprockets are worn out, change with a new chain + sprocket set. Chain wear out can be seen if the chain moves laterally(side to side).

4) Engine Oil - No matter what anyone says, get the engine oil changed to a good semi synthetic one, Motul 5100 is a good choice. I'd even sugegst changing the air filter as its a foam based so costs less than 100 bucks.

Once all these things are done, your bike will perform well. and if there's any other issue, you would be able to single it out. When too many things are wrong with your bike, it becomes hard to single out any particular issue.

What are the visual indications to change the chain sprocket, clutch plate?

Re: NS200 mileage problem & can't drive in traffic on low rpm

Chain: The chain has elongated too much so that it cannot be tightened anymore. Another criteria is improper wear – alternate areas that are tight and loose.

Clutch plates: The bike does low speed at a given rpm. For example, a new bike does 60kmph at 5k rpm and your bike does only 55kmph at 5k rpm.

Re: NS200 mileage problem & can't drive in traffic on low rpm

Are you sure about this method?

Re: NS200 mileage problem & can't drive in traffic on low rpm

This is one of the methods.... Worn out clutch plates causing clutch slip. I'm not aware of any other method. I'd like to know if any other methods are available.

Re: NS200 mileage problem & can't drive in traffic on low rpm

Have you also experienced this white color

Re: NS200 mileage problem & can't drive in traffic on low rpm

The bike doesn't quite pickup in lower RPMs. Can you please tell me what should i do.

Re: NS200 mileage problem & can't drive in traffic on low rpm

Have you fixed all other issues bro??

Also please state the exact RPM you mean by low RPM. For someone who always lugs the engine, 5k RPM can be high and for someone who rips the engine, 5k RPM can be low. So please specify the RPM.

Re: NS200 mileage problem & can't drive in traffic on low rpm

Ya gave the bike to servicing. but they r telling to change chain sprocket.
