Is there any difference between the wiring kit of RX 135 and R X G. When I asked for the wiring kit the guy asked specifically whether its for 135 or R X G. If so where it differs. Please clarify this doubt.

JD, i have gone through the Pics of Cylinder kit as well as the Con-Rod assembly in detail. I am afraid, these are not the original ones. The RX-K OE Cylinder has '4Y201' marking on it & even the Con-Rod should have '4Y2' marking on one side & 'YAMAHA' on other side, else it is something else.

Does this apply to Rx 135 also. The part number starts with 2YA. In the drawing in parts catalogue, there is YAMAHA written on one side.
What about 2YA? Is it written on the other side.
Apart from the connecting rod is there any marking on the flywheel to check the genuinity of the crank assy?

Ideally the crank assy should have the marking 2YA on the connecting rod on one side. Watchout that there are crank being sold by YASS without 2YA.

Thank you Sree and Dual disc. Great help from your part. I will definitely keep in mind the markings to check the genuinity.

Seniors, need some help here..

Can someone tell me the measurement of exhaust port of RX135 5 speed block taken from inside the liner? If not, can someone take a measurement of the stock setup and let me know. Ideally I would require length and height, in millimeter if possible or cm. This would help to know if the cylinder is ported while going to second hand one, though there are others to fiddle with.

To my knowledge, both 100 and intial batch of 135 (RX135 and RXZ) (until the 5 speed type casing) they both are same. The 5 speed casing came with small size oil pump and was even told that we cannot caliberate the oil flow unless the preceeders.

I am having a doubt on setting the height of carburetor float in my rx135.
And it is emitting a lots of smoke in the beginning. It is running is std size bore.
With new crank seals and bearing.

Dear All,

I am listing down some basic differences & similarities between 4-speed & 5-speed RX135 (Includes RXG & RX-Z), which will help people to differentiate & learn more about these legendary series once produced in India.

1. Bore Kit (a.k.a Piston-Cylinder Kit / Barrel / Block)

4-Speed - '4TL00' with OEM "ART" STD piston '4Y201', Rating: 12BHP @ 6500RPM
5-Speed - '4TL10' with OEM "ART" STD piston '4Y201', Rating: 14BHP @ 7500RPM

Note1: To check the originality, the LH side of Cylinder (Gear shifter side) has â€4TL00â€™ or â€4TL10â€™ marking along with â€132cm3â€™ (which is the displacement) and the RH side (Crank Kicker Side) has the batch of manufacturing, for ex., E1, E2, E3 or E4 (All of them have exactly similar performance, people who swear by performance of E1 being the best, is all crap.) Also if nothing is mentioned or some other type code is mentioned, then the Cylinder is a fake, except for '4Y201' which is the original block of RX-K.

Note2: The Cylinder packing has the following description on it:

1. RX135 4-Speed / RXG / RX-Z 4-Speed: "Cylinder Kit RXG"
2. RX135 5-Speed / RX-Z 5-Speed: "Cylinder Kit 5-Speed"

Note3: Displacement calculation

For Std RX135 being a single cylinder engine, we have the following inputs,

Bore Dia = 58mm
Bore Radius = 58/2 = 29mm
Bore Radius Squared = 841mm2
Stroke Length = 50mm
Pi = 22/7 = 3.142857 (Corrected upto 6 decimals)
Number of Cylinders = 1

Displacement in mm3 = Stroke x Bore Radius Squared x Pi x No. of Cylinder
= 50 x 841 x 3.142857 x 1
= 132157.143

Displacement in cm3 = 132157.143/1000
= 132.157 (Corrected upto 3 decimals)

2. Piston Kit

The OEM Piston kit for Indian RX135 series are from "ART" Japan. For Indian models piston sizes from STD to 0.5mm are available (in steps of 0.25mm). On careful observation of the piston, one can identify if it is original or not. Simply turn the piston upside down & inside we can see "ART" & "4Y201" clearly written. This is the proof for original piston. The piston kit essentially comprises of

ďż˝ Piston (STD/0.25mm/0.5mm)
ďż˝ Piston Rings
ďż˝ Piston Pin
ďż˝ Clips

Note: The pistons are the same for RX135 4-Speed, RX135 5-Speed, RXG, RX-Z.

3. Carburettor Assembly

The OEM Carb assembly for RX135 is Mikuni / UCAL Mikuni. The Carb assembly are different for both 4-Speed & 5-Speed versions.

4-Speed: '4TL 01' with Main Jet = 165 & Pilot Jet = 17.5
5-Speed: '4TL4 20' with Main Jet = 135 & Pilot Jet = 15.0

These are VM type of Carburettors manufactured by Mikuni & both are 22mm. Additonally VM24 & VM26 are used for RX available in South-East Asian countries (Like Singapore, Indonesia & Malaysia) and in South American Countries (Like Peru, Argentina & Brazil). The details of these are given below:

VM24: '2YA 00' with Main Jet = 145 & Pilot Jet = 20.0
VM26: '55K 00D' with Main Jet = 210 & Pilot Jet = 22.5

These carbs (VM24 & VM26) are direct fit to Indian RX135s with some minor jetting changes required based on the Power output of the engine.

Note: The type code is mentioned just above the 2-T oil Inlet in the carb, with that the originality can be confirmed.

4. Head Assembly

The heads are also different for 4-speed & 5-speed. The type code is mentioned below:

RX135 4-Speed: '4TL5' written on inner side (Top) of Head (For OE fitting Catalytic Converter type)
RX135 4-Speed / RXG: '4TL00' written on inner side (Top) of Head (For OE fitting Chrome Silencer)
RX135 5-Speed: '09L' written on inner side of Head

5. Clutch Bell Assembly with Primary drive

The clutch bell assembly are the same for 4-speed & 5-speed RX135 (Including the number of Clutch plates), but it is different for RX-G. Below are the differences mentioned:

RX135/RX-Z 4-Speed/5-Speed: Main Bell = 74 Teeth
Primary Drive = 19 Teeth

RX-G : Main Bell = 71 Teeth
Primary Drive = 22 Teeth

6. Chain Sproket

The sproket (Front & Rear) are all different for entire RX series. Detailed info given below:

4-Speed: 16T / 34T
5-Speed: 15T / 38T
RX-G : 15T / 37T

7. Gear Box
The Gearbox are obviously different for 4-speed & 5-speed. Details below:

4-Speed:
1st = 35/11 = 3.182
2nd = 30/15 = 2.000
3rd = 26/19 = 1.368
4th = 23/23 = 1.000

5-Speed:
1st = 35/11 = 3.182
2nd = 30/15 = 2.000
3rd = 26/19 = 1.368
4th= 24/22 = 1.091
5th = 22/24 = 0.917

8. Engine

The engine may be classifed based on Top End (Included Cylinder+Piston & Head) and Bottom End (Includes Clutch Assembly, CrankShaft, Engine Bearings, Crank Kicker, Engine Cases, Clutch/GB Covers, Ignition coil, GearBox Assembly etc as major components). Most of these items are already covered in points 1 to 7 above.

Note1: The RX135 4-Speed & RX-Z 4-Speed share the same Engine, likewise RX135 5-Speed & RX-Z 5-Speed share the same Engine.

Note2: The CrankShaft Assembly is the same for RX135, RX-G, RX135 5-Speed & RX-Z.

Note3: We can identify looking at the Engine number if the Bike was a 4-Speed version or a 5-Speed verion. Check the details below:

1. RX135 (With Chrome Silencer as OE fitting): 1L5 XXXXXX
2. RX135 (With Catalytic Silencer as OE fitting): 4TL XXXXXX
3. RX135 5-Speed: 1L7 XXXXXX
4. RX-Z 4-Speed: 1L3 XXXXXX
5. RX100: 1L1 XXXXXX

P.S: The RX135 5-Speed never came with OE fitted Chrome silencer, the OE fit was the Big Hot-Tube type catalytic converter Exhaust.

Any comments/additions are most welcome. Hope you all enjoyed this read.

I request all senior members to help make this thread sticky, so that all the RX enthusiasts are benifitted by this & it would avoid new joinees to ask unwanted questions. I sincerly request the moderator to look into this.

Thank you.

-Karthik..

Can you kindly post the same details for ESCORTS YAMAHA RX100 ? It will be very helpful.
