Re: Bajaj CT100 DX

Maybe my mechanic gives me special rates, as my family's bikes have been around him for servicing since decades now.

If you are not confident about their quality of work, reboring may be a bad idea, as if the problem persists at same level, you will not come to know till after a few weeks. Requiring you to put in more money to do the work at the ASC.

Do you see white smoke from the exhaust if you twist the throttle hard?

If you don't, then you still have time, as amount of oil being burnt is not much. Keep an eye on the oil levels till you get the work done.

Regarding BSVI bikes, might as well purchase new emissions compliant vehicle than not or atleast get a massive discount a few days prior to the deadline.

Re: Bajaj CT100 DX

About a month ago, i took my bike to nearby mechanic and he told it will take Rs 4000 for reboring. Another known mechanic suggested me to take to ASC since they will change everything with warranty but that is out of option now as it is costly. By the way, did you say the approx 2K is for reboring and also changing piston & rings? If the whole repair costs around 2K or 2.5K I m ready to fix it immediately. I think i need to keep checking with the other mechanics for cost but still I dont know how skilled they will be working on blocks and pistons. I will also need to do this as soon as possible since this issue should not create any other issue with engine.


Regarding BS6 Bikes I don't know the benefit. I need to read about it.

Regarding E-bikes, I came across Okinawa ridge. It seems to give good mileage and cost seems to be okay. However, no one owns it that I can directly check with.

Re: Bajaj CT100 DX

Hi.
Thanks I am safe here. Hope you are too.

You are burning engine oil, hence the dropping levels of engine oil.

Like I had said in one of my previous posts, you will have to rebore, change to a slightly bigger piston & rings - approx. 2K in Mumbai my local mechanic.

Regarding this expenditure, do you want to put in this money?

Next year renewal of registration & environment tax (a.k.a. green tax) will need to be paid.

I know you don't want to sell the bike. However do consider it.

Reworked blocks and pistons are highly dependent on the skill of the concerned mechanic.

A new block from ASC will set you back by 5500 + labour (approx. 1500 maybe) + 18% GST give or take it will come up to 8300.

Resale value of our bike now may be twice as much at best. Now add green tax and registration renewal amounts to cost of repairs.

I urge you to strongly consider feasibility.

If you are intent on keeping the bike, then consider a trustworthy mechanic locally who can oversize your piston and resolve the issue.

Wait for the BSVI bikes to be released, as from April 1, 2020 BSVI sales mandatory.

Have you considered any of the E-bikes?

Re: Bajaj CT100 DX

Hi, How are you doing? Hope, you are safe from the rain and flood there.

I have a strange issue with my bike's engine oil level, it's getting low after few weeks of top up. Finally took my bike for service today to service center, the mechanic said cylinder block needs to be changed and quotes around Rs 5500 + labor. I am in a dilemma now. Not sure I need to spend that much. Already for the service today I ended up spending Rs 2200 (around 1023 for changing few spares & 1186 on labor). GST alone comes to Rs 350 . Regarding engine oil level getting low, I told them to put a new ring in the oil level gauge as I noticed blackening around the gauge and so I suspected leakage. However, not sure what to do further on that issue. Please help me out here.

Also my bike is completing 15 yrs by april next yr and so I need to re-register. I am not the kind of exchanging or buy-sell guy and so planning to use CT 100 for my local rides but buy a new bike/scooter for highway rides. In another 6 months time, i will have to buy a new bike/scooter. Again looking for a vehicle giving good mileage and comfort ride in both categories (bike/scooter). Budget would be around 50K - 60K. Any suggestions will be helpful? I have 6 months time though to decide.

Re: Bajaj CT100 DX

Indicators either wire / bulb. Since both are shot, just check the wiring by removing the seat & checking for any loose connectors.

Front fork oil seal needs to be changed in all likelihood to stop the grime / oil leak from the forks.

Checklist - use the one in the user manual.

Regarding a good mechanic, first know what needs to be done. Ask questions. You may end up stumbling a few times before you find a good one.
The extra money you spend will be tuition fees for this learning experience of identifying a good mechanic.

All the best.

Re: Bajaj CT100 DX


No oil leakage on the ground where my bike is parked. I am planning to take my bike to the mechanic. Please help me out here. Besides engine oil problem, there is an oil leakage found in the front Fork tubes (both sides) couple of days back. I used to notice the black carbon like dirt in fork tubes and wipe them off before but now there is a oil leakage itself. Both indicators are not working now. Not sure if its a wiring issue. My bike service is also due. I need to find out a good mechanic this time instead of giving service in a Authorized Service centers (as they are charging too much for service). Do you know what all should I ask the mechanic to do as part of the service apart from above issues i mentioned? Is there a checklist of some sort? How can i choose a good bike mechanic? All these questions are delaying my bike service?

Re: Bajaj CT100 DX

On level ground on the main stand, you needn't have to tilt your vehicle to see the oil level.

Are there any obvious points of oil leakage on the ground where your bike is parked?

Is the area around the clutch cover i.e. RHS kick lever side wet / oil stained? Look on the underside as well. Check the area around the drain nut. If there are wet areas / oil + dirt stains, then the gaskets in that location will need to be changed.

If above is absolutely normal then, is the exhaust smoke white?
Are you hearing any abnormal sounds when the engine is running?
If yes, then you are burning the engine oil. The piston & rings would need to be changed.

Get your bike washed thoroughly. Check visually for any cracks (very highly unlikely) on the underside.

Apart from these I can't think of any other reason why your engine oil levels should become low.

Re: Bajaj CT100 DX


Question on the engine oil - I have changed the engine oil (shell advance 20w40) in March and the bike ran approx 2000 kms till date after the oil change but now I am not able to see the engine oil in the oil level indicator. When I park the bike using straight stand and check at the engine oil level indicator it does not show the oil at all. I have to tilt my bike a little bit towards the oil indicator side to see the engine oil. This looks strange because I have seen oil start to get dark after some period of time of oil change or bike crosses approx 4000 kms after oil change but the indicator always used to show the oil level. Something has changed in the recent time though I did not feel anything different while riding the bike. Also, the last time when I did the oil change the mechanic told me he could see only a little amount of the old oil. Do you suspect any issue with the engine? Is it consuming too much of engine oil?

Re: Bajaj CT100 DX

Yes for 1st part. You need to strip very less wire approximately 3mm on both ends. Try not to exceed the thickness of the insulation material when you use the tape.

For 2nd part i.e. step 7, use the hot gun type glue. Atleast your indicators will remain original. The OEM ones will break at the bolt / nut side, with the stud bolt coming out of the black end when the nut is tightened.

Wait for the glue to dry completely and then place the orange glass and tighten it's screws.

Re: Bajaj CT100 DX

Thanks! The indicator was working before the wire got deattached. I will need to try step 5, though I am not sure i will be able to strip off the wire as it got cut too close to the hinge part. Is this why you want step 1, 2 and 3 be done so that i will get some wire to strip off?

Step 7 - I will have a problem with inserting the black frame because as i told earlier the hinge part was already damaged near its end. Are you able to notice this in the picture? The end of the hinge has some damage.

Re: Bajaj CT100 DX

Don't change your indicators. It is a bit of Do It Yourself.
1) Remove your seat.
2) Trace the wire from your left rear indicator upto it's 1st interface with the main wiring harness.
3) Use a 14/15 no. Open spanner to remove the indicator from the mudguard (purple)
4) Using a Phillips head screwdriver, remove the screws indicated in yellow.
5) Strip off some of the wire indicated in red and joint the two ends and use Electrical tape on it.
6) Remove the orange glass and reflector of the turning indicator.
7) Insert the black frame of the indicator on the "hinge" part.
8) Now use the limbs on the reflector to fix / lock in the hinge part.
9) Test the working of the indicator.
10) Reinstall the orange glass and then fix the indicator on the mudguard.
11) Connect the wires green to green and the stripe to its colour.

Job done.

Re: Bajaj CT100 DX

Here you go. As you can see in the picture the Hinge where I plug in the indicator got damaged a long back. Tried applying quickfix and wrapped adhesive tape couple of times but it won't stay there for a long and comes off in few days. Then I also let the indicator hanging like that for some time and it caused the green wire cut off. Mistake from my end.

Re: Bajaj CT100 DX

I didn't understand Hinge in rear indicator.
May you please share a picture?

Re: Bajaj CT100 DX

Chain Sprocket issue is fixed in the Service center by tightening the chain. What is the price of the indicator light? My Left rear indicator has got one wire cut and the hinge is slightly broken even if I apply quickfix it is coming off in few days.

Re: Bajaj CT100 DX


Hey Dude. Gone through the pictures. Your Jawa looked very nice after renovation. I have heard the sound of Rajdoot, Yezdi, Enfield and Bullet in my childhood days but Jawa. How does it sound by the way? I mean it closely resembles any of the above?.

About my CT100, the squeaking noise in my front wheel has been fixed by the mechanic. Interestingly, he said the issue is due to the speedometer cable. He pulled out the wire from the cable and applied some grease/oil to the end and the noise was gone.

New issue is I begin to notice some sound when I change gears (like from 3rd to top). Something hits 2 or 3 times and once I accelerate after changing gear there is no noise. Mechanic says it may be due to the Chain sprocket but I changed the chain sprocket only during my bike service last month. I am planning to take my bike to the Service station sometime next week to see if it's due to the Chain sprocket. Too bad the streets near my house have bad roads and so I keep holding bike's clutch so often that I am not sure that is causing the chain to get frequent loose. As you know the other issues (like indicator, mirror) are just cosmetic ones and so I can take them up slowly.
