Actually want I meant is about RXZ/RX135.

For RX100 you can get anything as even we got the "Authentic" RX100 in India which is same as RX100.s seen in other parts of the world. But let me tell you that the part you get in Malaya may be also be "Made in India" as most of the 100.s parts are going from India/Mexico etc.. Beware.

Guys,
This could sound lame but since I am new to RX, I need to ask this.

What is the correct Air Pressure for the RX135? Currently they fill it to 26 and 36 PSI at Front and Rear respectively. Is is correct?

Let me know.

Siddharth - The problem is not with the KLM make bore kits. Its with tuning with Indian set up. There has to be fine tune here and there and would involve lot of R&D unless you intend to see yourself.

Thank you, @georgev. Will keep that in mind during the next fill up. BTW, how does having higher air pressure affect handling and FE?

Since we are on the topic, I would also like to know the right Tyre size for the RX135? I may have to replace mine soon. Would be good to get some suggestions from you all experience follks.

more air means less contact patch, less grip,less wear , hard ride

2.75 X 18 F (17 inch tyre in the front improves handling as per some experts)
3.00 X 18 R

Michelin M45/ Sirac

Yes, That's the OEM Tyre Size for RX100, RX135 and RXZ. I believe 5 Speed version RX 135 and RXZ came with Front - 2.75 x 18 and Rear - 3.00 x 18 IIRC.

Hey BHPians,

Though I have posted my bike's pic in another thread, I am re-posting it here. Just for the sheer love for the 5 Speed

I am in the process of restoring my Yamaha Rx135 4 speed. Still running on stock engine.

I opened the engine a month back. Did a full decarb. But it has resulted in noisy run. I think this sound will settle after carbon deposits back. The power is good but the yamaha sound is missing.

I plan to the following:

1) Engine Rebore
2) Consider the possibility of converting it to 5 speed

The firing has lost the RX sound which is only noticeable at lower rpms. At higher revs its just not there. I know that the 135 doesnt sound as crisp as the 100, but I want it to be as close as possible. I want that nostalgic firing back.

Please guide me though the process.

Also, bombay guys, please suggest me a good garage where I can get the work done. The mechanic has to be good and experienced in doing it. I would preffer it close to Vashi, but if the mechanic is good then dont mind going anywhere.

Get your complete exhaust silencer assembly decarbonized. The lack of crispness in the engine sound could be due to excess of oil deposit inside the silencer.

Even I am interested in converting my 4-speed RXZ to 5-Speed. Anybody tried it here?

4 speed conversion to 5 speed : just the gearbox conversion along with sprockets it should be easy (ok if not easy it is doable) but if you are looking for complete conversion i.e with 5 speed bore : AFAIK 5 Speed bore availability is almost nil :(

I did the decarb. The firing sound is there. But there is a sound coming from the piston thats overshadowing the firing sound. IMO it could be piston slapping sound. I think if I get it bored and use a bigger piston, this problem will be solved.

It will depend on the availability.

@Mumbai guys: Please recommend a GOOD mechanic who can do this and who has already done such jobs.
