Re: My new Yamaha RX 100. Need help!

1) Either not tightened properly or a worn out chain & sprocket kit
2) Flooded carb with lean tuning (I assume)
3) Piston slapping noise / crank noise
4) Check if it is OE silencer with proper core
5) Autolube + Premix is safe bet, any branded oil should do the job
7) Speedo : 500/-
Pilot box assembly : 110/- each
Kicker : 360/-
Rear mudguard/fender : 9xx/-
6V Battery : no idea, I suggest for 12V conversion
Side Utility box : You mean the tool box? around 100/- (i don't remember if it includes the lock)

Re: My new Yamaha RX 100. Need help!

Thanks for the approval and reply.

1) How to check if its an OE silencer? Any markings??
2) Autolube + Premix means fill up the oil tank as well as mix it with petrol? Is it okay to do that?
3) Does 12V conversion also call for a change in the wiring or existing ones can be used?
4) Please suggest me a good mechanic in Chennai (I'm from Mogappair area) and should I get the parts on my own or just leave it to the mechanic?

Sorry for too many question but I'm curious.

1) Hard to differentiate clones, but still with the welding (mostly the inner baffle spot welds) quality we could identify. Few fake silencers were very light in weight and came with different position for inner core screw hole
2) Add 1% (or max 2%) premix along with autolube (for 2 reasons, to keep the fuel tank rust free, as a guardian angel in case of autolube failure)
3) Existing harness can be used (coil end socket need to be modified if you are about to use 135 coil. If it is only a rewind job, no modifications required)
4) Sorry, I don't have any contact from your area

Hi Aargee and Sriram,

I really need your help in restoring my RX100.
Pls suggest a good mechanic in Chennai.

Re: My new Yamaha RX 100. Need help!

Hi there,

As a forum member, all those issues you facing are rectifiable. Hope that gives you a confidence. Here there are many who had blogged their restorations so you need not worry about bike issues. Everything can be resolved and bring your bike back to stock or how it is supposed to be.
[MENTION=65331]Mr.Boss[/MENTION] has already answered your questions and now you have a direction. He is another senior member of this form who could give you a good guidance.

I would only say .. read read read the restoration threads to understand what is what. There are several restoration/performance builds threads available from years ago.
Not all would make sense when you read them for the first time, atleast get familiarize with terms used etc.

Remember, RX spares are not in regular supply and many core components are discontinued. So kindly seek guidance if you were told to change any parts by mechanics.

Another useful tip that I can give you is..

when you post your query, be detailed, if you don't know what is it called, post a picture and mark it, describe as much as you can... vehicle condition, how it sounds, when the issue comes up, when does it stops, etc. Since members are not seeing the bike in person, so the words might not be describing exact issue. It also helps others to understand and narrow down the issue and suggest you better solution.

-Sriram

Probably worn out sprocket

2. When I park the bike (in side stand or center stand) for a few hours, the bike doesn't start easily. I have to do 5-10 kicks with the choke on to start the bike. Even after starting it takes time for the bike to move in 1st gear. I kind of chokes when I accelerate and it gets switched off.
What could be the problem?

Check the carb. If carb tuning doesn't help, then check the jet.

Not exactly sure what kind of noise you are referring to.

4. The sound of my RX100 is different from the other RX 100's. It sounds on a much lower note (bass kind of sound). Not the usual crisp and clear RX sound. What should I do to get the stock sound?

First check if there is too much of soot in the exhaust. The previous owner might have cleaned/chromed the outer without cleaning the carbon deposits on the inside. If the inside is clean and still the exhaust note is not crisp, then check if the exhaust is original with unmodified core.

5. Since it's my first gear bike and that too a two-stroke, I am new to this 2T oil thing. Which oil should I use? Is using the autolube advisable or shoud I mix it straight to the petrol tank as I usually do? Also the quantity of oil to petrol.

Premix will avoid rusting inside the fuel tank but you might end up cleaning the carb frequently compared to autolube. One risk of autolube is that you never know when it might stop working and if it stops then you would risk your engine with a seizure.

6. I want to do a complete checkup or service of the bike or even restore it to a better condition. Please recommend some trustable and good mechanic anywhere in Chennai who can fix these issues for me. (I'm from Mogappair area).

I know a mechanic who is very proficient with RX. In fact, he was the one who rebuilt an RX100 for my friend from scratch and also retro-fitted it with a 5th gear. I too maintained my RX135's services with him. But, he is near perambur. Let me know (PM me) if you still need his contact.

Re: My new Yamaha RX 100. Need help!

Hello xBhp'ians,

Sorry for the delayed reply. I got few of the minor issues that i faced sorted out.

Now I need your suggestion regarding the chassis of RX100.

Pls look at the images below:

Considering the bike for a long term usage, should I get a new chassis or get it repaired by welding (if possible)?

If it can be repaired, where?

If new chassis is to be purchased where can I get one in Chennai? and its cost?

I also read threads regarding the legal issues for changing the chassis. Pls clarify.

Thanks in advance.

1) Looking at the extent of damage I suggest to get it replaced with a new one
2) If you are still looking to get it repaired, PM me. Remember, the cost of repairing + painting should be close to the new one
3) Safe bet - from authorized dealers (if they are ready to support you) I wait for Sriram to give a reliable pointer, else PM me. Should cost around 4k
4) New frame with proper invoice shouldn't be an issue

Thank you for the reply.

If cost of repairing and painting is going to cost close to new ones then I might as well go for a new frame.

A local dealer in my area quotes a new original frame at around 5K and he says its genuine Yamaha part. but I don't know if I can rely on him.

I would like to know where to get a new original frame.

Re: My new Yamaha RX 100. Need help!

The chassis can be restored. The advantages of restoring the chassis us that you don't have search for she'd to punch number.

As [MENTION=65331]Mr.Boss[/MENTION] said, we need to take a due consideration of cost as well.

I would rather suggest you to speak to RTO to know the procedure to change chassis.

If you buying chassis, preserve the bill for RTO documentation.

I would suggest you to ring Mr.Boss to take it further.
