The very Old RX100 (1986, Japan) - Page 2 - xBhp.com : The Global Indian Biking Community

@Santhjit/All - When you say Japanese engine, does that mean:-
your bore is from Y series? Connecting rod is Made in Japan? Apart from outer crankcase depiction. What would it take to be more precise when we badge as 'Made in Japan' RX100?

satishg · 09-14-2011, 08:06 PM

congrats, 1986 models had Y2 barells? 1987 was G1, but meters read Yamaha ...

Yes, its written 'Y-2'. Regarding other parts Im not sure. But what I have heard from others is, for Japan RX 100 major parts are from Japan.
In the 'carburetor' also its written '36L00' and 'JAPAN'.

Another thing I have noticed is, on the crankcase near to gear shifter its written 'Made in Japan' and inside the crankcase cover for Oil pump its written 'Rajdoot'.

See the photos I have attached..
1)'Made in Japan'

2)'Rajdoot'

Between, whats special with Y-2 barrels and G series?

Others please share your knowledge on the queries by 'SriramEfunds' and 'satishg'.

My 1986 RX100 (registered 30-9-1986) had the same combo of the rajdoot badging on the oil pump cover ... Y series barrels were imported from japan ... G series were made in India .

1986 batch RX100 were CKDs, Engine and Transmission were completely imported from Japan. It was only assembled here in India. Thats what I am told. More Knowledgeable members can add/clarify.

@Sanjitjoseph: Congrats on your acquistion! This is an expensive affair so be forewarned

Out of the parts you've listed, except for bore rubber, everything else is easily available. I would suggest you to take a look at cycle parts/rubber parts/cables and replace as necessary. While at it you may also want to take a look at your seat assy. With age, the plate tends to corrode. Unsolicited 2p. Hope u dont mind.

That's what I thought too. When you say transmission? did you mean crank assy and gear box or something else? I'm sure we are going love this fact-finding of lost era!

The numerals after the letters Y or G are production series numbers denoting either different OEM manufacturers (Yes even Yamaha Japan does not make everything themselves) OR minor tweaks / improvements to the casting and / or portmaps ...

Yes sir .... even the frames were made in Japan ... also I have heard (very reliable) of a Nov 1985 RX100 and I OWN a May 1985 printed workshop manual ....

But I also think the 1985 batch was sold in north India only ....

I have also SEEN a CB-points version of RX100 imported into India in the early eighties !!!

Isn't RX100 initially produced in Japan only for Indian market? Was that ever catered to their own country? Offcourse, I was going through some reads on the internet that RX100 was available in Argentina/South America even in recent years. Did not read if they were Japan produce.
