I'm working on my RX and I have a few questions about my bike:

Question> will they have the ART pistons available there or should i have it ordered from one of you gentlemen? I just need a good piston it doesn't have to be ART, just whichever u recommend. I think the mechanics here like to use USHA pistons ....the name itself is scary.

ART pistons will defnitely NOT be available with the machinist. Its a bit too expensive for the clientile usually these guys cater to. ART came as OE for RX-135. Why don't you begin by placing an order for it in a YASS? My pick in among Hyderabad YASS would be Patnys. If you do have to resort to 'sourcing' it from 'friendly two strokers' please be guided about the rate. I paid ~1.1-1.2k almost a year ago for this.

2. Tank Cap/Cover makes a lot of vibrating noise. If i touch it with one hand while riding, the noise quickly stops but if i let go... rattle rattle rattle. Last year I changed the oil cap and the sound went off but again its back.

Question> Any solution for this that I can do by myself? Or would u recommend a gooder quality cap that one of you gentlemen might be able to sell me?

I am currently facing this issue on my RX100. Did you change the lock on the tank cap? I am not aware of any ingenious solution. You can buy a tank cap and use the lock that comes along with it or buy an used one which doesn't have this issue.


Question> what do they do to their exhausts to make them get that trebly fling fling sound? (sorry for my weird description). I chopped my muffler and now it sounds better but still FLAT... not vibrant like an RX 100 sounds, i hope u get what i mean ...i've heard some SEXY 135's in bangalore. what a note!

This question has been answered in detail by Sriram in multiple threads. I'll just say Bangalore strokers probably sound better because we have better technicians to work on RXs here.


Question> how can i reduce the vibrations at the handlebar ends as well as at my feet and bum? what about putting (is it) hydraulic shock absorbers at the rear?

You need to diagonose the problem rather than treating the symptom. Vibrations can be for host of issues. How is the bike performing? Accelerations, cruising, cold starts, kmpl, etc


6. Second gear not hitting smoothly: I'm guessing most of you have faced this problem on ur RXs. When i shift up from 1 to 2 sometimes it doesn't shift and i embarrass myself coz i've raised the throttle but i'm somewhere between 1 and 2 (like neutral) and everyone's seeing me NOT jumping forward but with lots of show-offy 2-stroke sound

Are you coming from 4strokes? If yes, then eat well and do some leg exercises :-D

7. Autolube pump

Question> if i want to NOT be stock. And mod my bike to go the fastest it can and strongest it can, do i need the autolube pump? my mechanic stole mine but i'm thinking of getting a new one coz some people say its good for the engine to have one (even if i put 2T oil in the main petrol tank with petrol).

What is good for the engine and your pocket is constant accurate metering of 2T oil. You decide which method is the best :-)

Hi, guys!

First, I'm guessing I've posted this in the wrong location so please tell me how to get to the 'Help Me' section for further notice. Thank you sincerely.

I'm working on my RX and I have a few questions about my bike:

1. I finally got a friend's bike to keep with me for 2 weeks so now i can get my bore rebored. i'm going to open it up and take just the bore (piece) with the old piston to the most popular reboring place in hyderabad, 'diamond reboring' in naampali i think (near the railway station).

Question> will they have the ART pistons available there or should i have it ordered from one of you gentlemen? I just need a good piston it doesn't have to be ART, just whichever u recommend. I think the mechanics here like to use USHA pistons ....the name itself is scary.

ART though not easy to find is priced at Rs. 1384/- . available till size .50mm. Find out what size are you going to require.

2. Tank Cap/Cover makes a lot of vibrating noise. If i touch it with one hand while riding, the noise quickly stops but if i let go... rattle rattle rattle. Last year I changed the oil cap and the sound went off but again its back.

Question> Any solution for this that I can do by myself? Or would u recommend a gooder quality cap that one of you gentlemen might be able to sell me?

Try to check whats making the noise. the hinge can be loose or the rubber gasket that seals the cap needs to be changed.

3. Bangalore RX 135s sound so close to the beautiful RX 100s..

Question> what do they do to their exhausts to make them get that trebly fling fling sound? (sorry for my weird description). I chopped my muffler and now it sounds better but still FLAT... not vibrant like an RX 100 sounds, i hope u get what i mean ...i've heard some SEXY 135's in bangalore. what a note!

Nitin would know better on this.

4. reducing vibrations on bike: the handle bar vibrates alot and so does the rest of the bike (which is common i suppose). Just one point in the right side of my back has been hurting like someone keeps sticking a needle in there constantly. I made the mistake of riding like this for several months now... finally got my Footrests bent back into alignment (the right one was higher than the left one) ...now i feel better after long 30 minute rides too.

Question> how can i reduce the vibrations at the handlebar ends as well as at my feet and bum? what about putting (is it) hydraulic shock absorbers at the rear?

One of the reasons for bad vibrations is unbalanced crank. Check if your handlebar is original.

5. digital speedometers

Question> any of you gentlemen use digital speedometers? I removed my full front assembly of the headlight and the gauges so i have a rally feel and i absolutely love it. and i put an autorickshaw headlight on there... exactly where the horn used to be - just replaced units. (i haven't put up any pictures coz my wires are all over the place and yawl will hate to see it like that)

Digital speedos can only be used with digital CDIs with a tacho out feature.

5. tools to keep on the bike: i noticed that my wheels will need 21 and 19" wrenches if i have to take them out on a trip (puncture maybe).

Question>how do u carry such big wrenches/spanners in the tool box? are there smaller versions of these that i can find somewhere?

Make a customised tool kit of your own for long trips. Also include a puncture kit and a foot pump.

6. Second gear not hitting smoothly: I'm guessing most of you have faced this problem on ur RXs. When i shift up from 1 to 2 sometimes it doesn't shift and i embarrass myself coz i've raised the throttle but i'm somewhere between 1 and 2 (like neutral) and everyone's seeing me NOT jumping forward but with lots of show-offy 2-stroke sound

Gearbox and shifters need to be checked.

7. Autolube pump

Question> if i want to NOT be stock. And mod my bike to go the fastest it can and strongest it can, do i need the autolube pump? my mechanic stole mine but i'm thinking of getting a new one coz some people say its good for the engine to have one (even if i put 2T oil in the main petrol tank with petrol).

Autolube is always good and reliable if the bike is maintained well. Yes a new pump can be found.

8. What kind of info will be required from me to have someone build a deadly expansion chamber for me?
Firstly, you will need someone real who knows chambers and has built a few calculated chambers.

Thank you, you awesome gentlemen! I've already learnt a lot from XBHP. Thank you in advance!

Reboring Doubt:

Please tell me, is there a lot of expertise required to rebore a cylinder specifically used for racing? I am just wondering if I can take my bore to the gentlemen at the most popular places and get their advice on size of piston needed and then have them rebore the thing for me and i myself find a piston to match the new bore size.

Nitin, please tell me if there is a risk involved and what it is... for me to absolutely have to go to a good RX mechanic to get my reboring done.

bore gauge: now on my purchase list.

johny

You will get two (or more) bore kits for the price of a bore gauge!! Just take it to Microtek in Bengaluru and be done with it.
