this might require a lot of cosmetics what is the condition of the engine?
and in my opinion if u r repainting the tank and panels make sure you get the Original RXG decals/ stickers ..i think they were the best design

re: 1997 Yamaha RXG Restoration - Now completed - Pics from Pg 5

Thank you

Engine is running in 1st OS piston and with some noise from Connecting Rod. Will be going with 2nd OS piston, new Connecting rod and bearings.
Regarding decals, this bike will not be in stock theme. Planning to paint it in bright blue color with RXZ decals (the one came with blue RXZ) + RX135 side shield monogram.

Good to see the restoration initiated.

Looking onto its rusted conditions, looks like the bike was lying from a long time.
Suggest start the job to get the powerplant right first thing, rather than looking into the cosmetics.

Start looking for the condition of crank cases for any cracks or other sort of distortion. You may never know how the previous owners had used it.

How is the condition of the fuel tank interior ?
Suggest to go for a new tank (you may want to change your color schemes though). A new tank will keep your powerplant healthy.

Where are you planning to get the re-bore job done ?

re: 1997 Yamaha RXG Restoration - Now completed - Pics from Pg 5

Thanks dude.
Yes, the bike was lying unused for about 6 months (in a open space, outside garage)
Already stripped the engine completely and confirmed there is no crack / damage in crank case. Fuel tank was replaced by the previous owner, checked and found it is in perfect condition.

Regarding engine work, I don't know the exact location. My previous RX135 reboring was done somewhere at pallavaram (my regular mechanic taken the bore there and done the job) and I'm quite satisfied with the quality of their job. So planning to stick to the same source now. Let me get the details from my mechanic and update here.

Thank you very much for the suggestions and looking forward for more suggestions / help.

Experts, need your advice. (please don't kick me after reading this question)

I wish to increase the acceleration without compromising the top speed.
Calculator inside my mind said go with RX100 sprocket (15/39 instead of stock RXG spec 15/37) This increases the drive ration by 5.43%
Now the calculator made some stupid calculations and said chain the 4th gear ratio same as 5th gear in 5 speed GB spec (22/24 instead of 23/23)

Will this workout?

re: 1997 Yamaha RXG Restoration - Now completed - Pics from Pg 5

Bring to stock condition first & then think about doing the mods.

May be, but at the cost of...
If you want to increase acceleration without compromising top speed, stay off from sprocketing - THIS IS BASICS

Just asking out of curiosity, are you feeling very desperate to complete the job or do you think there aren't enough experts around so as to start a thread here as well as Restoration - 1997 Yamaha RXG - Team-BHP

re: 1997 Yamaha RXG Restoration - Now completed - Pics from Pg 5

Thanks for the suggestions aargee.

Hope nothing wrong with that. You missed my posts in some other forum too. There are quite a lot of experts in each forum who may not be member/active members in other forum.
I suppose each and every suggestion may add some value unless and until there is a conflict.

re: 1997 Yamaha RXG Restoration - Now completed - Pics from Pg 5

There're several other forums too, I can suggest them for you; visit RDDDREAMS & you'll not need any of these forums

re: 1997 Yamaha RXG Restoration - Now completed - Pics from Pg 5

Quick update:
- Frame, tank, shields, engine & crankcase, hubs & front fork sent for painting. I heard from painter that he already started the work (Yet to confirm, will try to take some snaps by tomorrow)
- Silencer, new set of spokes, pinion holder, nuts & bolts sent for platting (Quality Metal Industries, Ellis Road) along with a set of old rims to gift my friend, total costed 3000 INR

Parts to be procured:
- Lock set (still roaming around to find the complete steel key type)
- Tool box
- Battery (mechanic suggesting to use a bigger one as I'm planning to fix the twin horns either from Pulsar or Apache, is it recommended?)
- Head lamp assy (will go for Swaraj Mazda / DCM Toyota reflectors, DIY by this weekend)

re: 1997 Yamaha RXG Restoration - Now completed - Pics from Pg 5

for battery you can use 4 amp ones from the es start passion or splendor should fit with min mods, thoug you are warned the rx has a weak lighting set up

re: 1997 Yamaha RXG Restoration - Now completed - Pics from Pg 5

Means the lighting will go poor after installing 4A battery?

re: 1997 Yamaha RXG Restoration - Now completed - Pics from Pg 5

nope , the battery charging might take a while, i think you can go for double horns with the stock battery itself

re: 1997 Yamaha RXG Restoration - Now completed - Pics from Pg 5

Standard Rx comes with 2.5Ah battery & the charging coil is capable of charging this; if you use 4Ah, then you're bound to keep charging the battery by running you vehicle slightly longer duration.

To understand this better, imagine a 10 liter water tank that is dispensing water at the rate of 1 liter per minute, so in 10 minutes, the tank runs dry. In order to prevent it from getting it dried, we will feed water to the tank from a lake. Let's say the water is filled at the rate of 1 liter per minute, so in 10 minutes the tank becomes full. For simplicity, let's not worry about tank getting overflow.

So if you increase the capacity of the tank to 15 liters, it takes 15 minutes for the tank to get full, however, the dispensing is still 1 liter per minute.

If for some reason, if your dispensing gets more (adding twin horns or buzzer or any other electrical additions), then the rate of dispense is more than rate of fill. In order to maintain the 10 liters capacity (or 15 in this case), you'll have to stop dispensing or dispense less than 1 liter per minute so that the tank reaches the required threshold quicker. Ofcourse, this situation is likely to happen even when the tank is at 10 liters. But if you add a clause stating that, inorder for the rate of dispense to be at 1 liter per minute, the pressure of water HAS to be at 10 liters in the tank, then, you can think about what happens when you dispense more & how long does it take to maintain the threshold level in the tank in case of 10 vs 15 liter tank. This is what I explained in the first sentence.

To make things simple, if you increase the capacity of battery, it's wiser to increase the charging capacity of your generator as well.
