Absolutely yes & I stay away from mods as well; had enough in life!

No mods boss; I'm still immatured enough to think, there's no replacement for displacement...old school fellow!
Yes, will ride down two-up to Bangalore & will remember to ping you before I come. Would be a fantastic experience after a long long time to RIDE down those memorable roads

Re: RX rebuild Using 3 Yamaha Variants

Worst thing today is to go by these social media for seeking news. Most of the time they are nothing but to create sensation. Haven't we seen that?

You know well that 2 strokes are always have high demand and the prices of both pre-owned and spares have become costly affair. Some frustrated soul timed the circulation of fake news while govt the emphasizing on emission norms for automobiles in a phased manner.

It's been a long time since I started a thread..lol

Re: RX rebuild Using 3 Yamaha Variants



We got brand new in everything; changed part by part; first the plugner kit, then master cylinder kit, then caliper kit & nothing availed. Finally gave up everything & stuck only with plunger kit (the same new one bought) & finally by several trial & error got the same old braking. So it was better than nothing at all & hence decided to stay with that

No UCAL, it's Micarb embossed only

No wonder!! It all seemed too fake despite buying from genuine spare parts dealer! I was cursing them to have cheated me, guess I will change my mind now.

Sigh!! Don't know what to say; I'm sure you've seen this (fake???) news - https://www.cartoq.com/yamaha-rx100-rd350-yezdi-banned/

Re: RX rebuild Using 3 Yamaha Variants

Never comes back but we can cherish by flipping back pages of this post.


After reading your post can think of two things....

1. We should first checked the Master Cylinder by removing the piston and thorough cleaning the inlet and replace it with new master cylinder kit.
2. Caliper piston O rings might have worn out. There is a red rubber grease to keep the rubber o ring in good condition.

If at all the above is checked, you can service them and keep it for future. Most of the time, issue lies in the brake lines where the air gets trapped.
A thorough pumping of brakes to let the air escape through is way to ensure good working.

We get Mikarb for RX135? or you referring to the last model of RX135 it came where it had UCAL MIKUNI embossed?

You'll not believe, the Yamaha OE quality has gone down that aftermarket brand named Diksha supplying better build quality.

2 stroke syncs our heartbeat better!

Re: RX rebuild Using 3 Yamaha Variants

Good old days Sri

Switched to Nissin master cylinder & this gold colored caliper kit (new setup). And it behaved worse than clutch. So once again went back to the (old setup) Pulsar setup of BYBRE master cylinder & caliper kit & unfortunately that also started behaving the same way. It sent a complete shiver not just nerves, but entire spine as well.

And then finally, we decided to stick with old one because we know for sure the old one works. So we went about troubleshooting, leaving the setup on the bike over night & next day removing the air bubbles. Gradually the bite started improvising & got back a very good bite, which is much better than it used to be.

So, that kit is now awaiting (or has been) to some other Rx.

Basically, I went for a little overhaul after 7 years to change the rusted parts, keep the Mikuni as spare & use Micarb instead, changed batteries & 4 indicators & the worn out handle grips. Most of them...replicas, no original ones, even from the most reputed shop...you know which one

Had to accept it & move on because even the good old Motul 20W40 (or even 10W40) SS is being replaced by 20W50

Re: RX rebuild Using 3 Yamaha Variants

Glad to see your post after years.

What exactly happened? The color change is visible. Is the caliper not giving you the bite?

Re: RX rebuild Using 3 Yamaha Variants

Nope; nothing; not even from the reputed dealers who were selling genuine stuffs 8 years ago...sad truth

Re: RX rebuild Using 3 Yamaha Variants

hmm happens , most of the oe stuff is still available though

Re: RX rebuild Using 3 Yamaha Variants

Haha...its a business on love

What I found is, there's almost no genuine parts being sold. Almost all are fake parts, out of the few parts ordered from a genuine Yamaha spare parts dealer, I hardly got anything genuine. Even this caliper kit was sold stating Gladiator's, it was a perfect fit to the front fork (Gladiator again), but, this is not original

Re: RX rebuild Using 3 Yamaha Variants

still in business???

Re: RX rebuild Using 3 Yamaha Variants

After nearly 7 years, this is cooking now...

No tell me, if I'd assumed too much; I might be overlooking on things

You are correct. There is no need to touch the cylinder.

Sriram & Nithin - Guys guys...I don't know how can I prove you people; I'm NOT working on cylinder/piston/bore/head (I feel like Adam Sandler in Anger Management )

Why should I've a backup on bore when I'm not working on it

Does upjeting & AM air filters involve in removing the cylinder piston kit I'm beginning to have my own doubts on my skill now

BTW, if I've UNI & 180 MJ, I thought the entire process takes not more than half hour apart from tuning; and the bike needn't be started during this process.

Do you guys think I'm assuming too much

Tks Yamdoot

Nitin - If meeting is the criteria, I only need 4 hours to meet you people ; allow my CBR kid (grown up from baby CBR ) to come from Mother-in-law's house...I mean...ASC

No two bikes can have the same state of tuning. but yes, mostly 17.5 and 180 it is IF they are genuine Mikunis. I cant say that about the cat as i stay miles away from such things.
