Rebirth of my 1987 Rx100

Wow!! Slowly slowly the beauty is waking up! Dying to see her in her all glory! Fantastic rebirth. I am voting for this thread!

kapiljolly79 · 23rd January 2009, 12:24

Thanks Amtak. Trust me, the excitement to see her all set and ready to fire up is amazing. I always look forward to the evening to get off from work and get to the garage. Will also post a pic of my work area, which sadly is mostly in a mess due to the neem tree leaves that get blown in. Otherwise, my junk is my gold. And I am sure other restorers will agree on the same. Thanks again for the vote.

Btw, may I ask what made you a fan of Shell? What difference did you find with Shell?

go for petronas if you feel motul is expensive though it is ..

fully synthetic is like 350 per liter..
semi should be around 200-250

^^^Thats much cheaper than Motul. But much more expensive than locally available brands like Castrol Jet X, Shell, etc. So does Petronas make any visible difference over these brands? Also, Petronas availability is a problem, here in Pune. :( Haven't seen it in a single shop, except one in Nana Peth. And gawd knows if its original...

Well, just paid a visit to the dealership during lunch hours. Picked up a few stacked away goodies. Two litres of Yamalube 2T oil, date of packing as you can see is feb99. Original is original.

Also got myself a set of the real alpha toyo accesories rear view mirrors that originally came with the 100's. PLus a few more nut blts that I needed. Pics as enclosed.

Jaggu · 23rd January 2009, 15:12

Why did you buy the Yamalube that was packaged 10 years back, oils have a shelf life! Better option is to get a genuine Castrol super TT.

Excellent restoration otherwise, while run in keep the oil pump setting to the higher side. Tool box was not there in RX they came with RXG.

kapiljolly79 · 23rd January 2009, 15:16

I agree they do. But even then, ten years will not make any harm to it. PLus, its sealed. Had been been like the 87, an 87 packing, I would have reconsidered.

Yep, will definitely be keeping the pump setting on the higer side. Not only in the run in, but for good. And a little more oil doesn't hurt. So will run the first few tanks by mixing the oil in the petrol itself. Better safe than never. Thanks Jaggu.

I agree with Jaggu. Like human's even oil has an expiry date. Not recommended!

you can get petronas from dream bikes at MG road..
all other brands you mentioned are mineral oil..
petronas is synthetic so it has to be expensive

Dont use synthetic for run in, it will prolong the duration. If you plan to add 2T in tank then keep the setting to normal, or else too much oil can foul the plugs as well as leave carbon in the exhaust port and the silencer, and yes pollution.

Ideally use oil in tank as a insurance for few 100 kms so that the oil pump health is determined, then set the pump to normal mark and leave it. These pumps automatically increase the oil feed based on throttle input and dont require more oil from tank. Ensure you bleed the pump and line for air and check and refill the reservoir tank every 750 to 800 kms.

kapiljolly79 · 23rd January 2009, 15:42

I also agree on the note of the toolbox. However, the RX also came with a 6V. I've moved it to the 12V circuitry. Some things can't be avoided and a re a welcome improvement. SO a nifty toolbox for a spanner and a cleaning rag is an added bonus to the bike.

Thanks again Jaggu. I must admire the details our fellow Bhpians are taking ito detail. Well, I hope this restoration is living up to it too.

Also, on second thoughts I'll go with what you suggest on the oil. What I shall do is I'll put that 2T in the 2T tank and mix Castrol 2T oil in the fuel tank with the gasoline. This will make sure the engine gets the oil it needs, and a little extra from the pump, and will also confirm the pumps proper functionality without risking the engine. Since oils are hygroscopic, until they're used, this old packing will not harm the engine in any way as its still sealed.

Jaggu · 23rd January 2009, 15:50

Chances of harm are very lil, unless some chemical break down has happened with the oil. If you ask me any advantage what so ever by using Yamalube is not worth that 250 bucks (2 cans), rather give it off.

On the other hand i agree lil tit bits that help are welcomed, though a shift from 6V to 12V is not cosmetically visible compared to a tool box, unless one changes the headlight doom or something

If you are not particular about looks, another useful upgrade would be the switch gear on the handle, from a later gen yam, they are straight fit (IIRC) and much more durable. If the connectors are not same, dont bother since chopping the leads is something which i would not do/advice.

Reason why i got into details? seeing you put so much effort and money one cant help, also advice against the mistakes one would have done in the past. ahhh those were the days.

That reminds me: Oil level float from samurai can be retro fitted with some jugad into RX tank, then connect the wire to neutral shift light wire on the gear box and voila you have a, 2T oil warning lamp. Cost some 200 bucks

kapiljolly79 · 23rd January 2009, 16:09

You do have a point. The oil can always go back. No issues on that.

As for cosmetic changes, I have the original Headlight dome but have opted to use a samurai dome for better focus. I am making a small compromise on a few things for sure. But in the end, it will be an 87 at heart.

As per the float circuitry, nah. The 2T tank has a level indicator in it and it works great. Just have to keep an eye on it. So will do with it. (Original)

It came only for a few years and was finally removed.

Switchgear, I will go with the original RX style. I still find that very comfy.
I have the new one which will be kept as a standby.
