saw this bike today lying in the neighbouring society's parking, how much would it be worth??

and also is it possible to restore it??? the body does need some work but i'm hoping that the engine would be fairly restorable considering that two strokes do not die that easily...

5k if he gives.. if not u can go up to 85k its worth every p

but will cost u another 15 - 20k to fix it and 35 - 40k if you go to some cheap cheater mechanic lol

you can restore it.. re bore slave is easy.. even crank can be reconditioned, only problem is radiator and you can get r15 radiator

RZ125. Parts are very difficult to get. Even if everything can be reconditioned, the powervalves are a pain. Is it for sale?

**revvhard** · 05-19-2012, 10:08 AM

wont it be possible to get parts from Malaysia or any of the other south east asian countries??

i do not kno if it is for sale, but seeing the sorry state it is in i dont think the owner would mind selling it off.....

It was never sold there. Europe, Canada and South America could be given a try.

I was about to start a new thread before I stumbled across this one here.

Read Joel's post about history of TVS-Suzuki bikes on tBhp. It got me thinking.

I have a Green 1999 TVS-Suzuki Samurai that was bought at that time for a whopping Rs. 42,000 on-road Bangalore by my dad. It was pretty expensive for what it offered - a 98cc engine developing 7.49 BHP @ 5500 RPM and like every other 2-stroker in India, torque figures remain largely unknown. Still use it as my daily commute though planning to move to a modern bike in a few months.

As far as the engines go, what was/were the differences between different 2-stroke bikes from TVS-Suzuki ? There was a 16BHP Supra SS (race spec) sold on custom order right ? This means if the engines share even something in common, I could do some mod work to pump the power of my Samurai atleast slightly. What would such an operation cost ? I'm completely unaware of the technologies behind these 2-stroke bikes that made/make them so popular for mods.

PS: Don't 2-stroke bikes have something called "torque" ? I only ever read mythological accounts of extreme pulling power from these bikes but never seen the actual torque in x NM @ yz00 RPM figures anywhere for Indian 2-strokes, while the power figures in BHP is readily available.

Two stroke Suzuki bikes in India came in many forms and some differences in the engines. While the chassis and engine mounts are common to all except the Samurai/Shogun/ Shaolin, there is a difference in the bhp and cc figures which you are aware of. The Supra was also last sold in the Showrooms in 11 bhp form . You could try some changes to your Samurai like porting, fitting a powerbox, a chamber or a Shogun muffler etc. to gain some power.

I believe RXG workshop manual has its torque listed as 1.25kgm@xxxxrpm. Let me go home and check the exact numbers.

EDIT: Screenshot of engine specs from Workshop manual attached.

What do each of these actions cost and what is the power benefit from each ?

Thanks for the information. Do you have any link online that tells torque of other 2-stroke bikes ?

TVS also have Shogun SS & the Shaolin SS, which is strictly for Internal Race use only.

Every rotating mass (IC Engine or Motor) has something called Speed & Torque, without which it wont make any useful power. Here is the General formula:

P = (2 x Pi x N x T) / 60

OR

P = (T x N) / 9550

Where,

P = W or kW

T = N-m

N = RPM

The pulling power of 2stroke is mainly because of Powerband which you can feel. Have you ever tested a superbike, like an R6 or a CBR? Even they have insane pulling power enough to do power wheelies upto 3rd gear in stock condition.

Kindly let us know how we can help you with your bike modification, rather than discussing about entire 2stroke scene here!!!!

Aware of it as well. But those are purely race-bred bikes.

Did some reading since I posted this question. Went through this thread and found some nice PDFs so thanks to whoever posted them

Alright man I am not questioning the power of 2-stroke bikes. I'm only asking why the figures were not published popularly in those days. Hope you know what I mean. We only have BHP figures. I'm talking from a statistician
s point of view

Kindly let us know how we can help you with your bike modification, rather than discussing about entire 2stroke scene here!!!!

Glad you asked the question. So here it goes:

My bike is giving a low average for the power it produces. Also early morning starts need 4-5 kicks and some choke. I've heard of MAX100's and other Samurais giving 60 mileage. Also heard Samurai is in a lower state of tune than it can actually be. Want to know what all checks and fixes can be done to improve these 2 magic words - power and mileage. Budget around 5k for these operations.

Problem with my RX-135 4S
I had recently completed my rebuild with new Crank, 3KA20 Block (YP-2) and new Piston along with necessary fitting and fixture. The bike started with first kick every time. Now problem is, it refuse to go beyond the speed of 70 kmph and also refused to accelerate quickly. Whenever open the throttle it will take a time of 15-20 sec before getting the speed but never crossed the 70 kmph mark and acceleration is very poor. My mechanic said that there is problem with reed valve but i don't think so. Right now i am very confuse how to short out this problem. Needed expert advice.....

Alot goes into the investigation as to why it is not crossing beyond 70kmph. Clutch assembly, Genuinity of the 3KA20, Port job, Reedvalve, carburetor, jetting, AFR, compression, air leakage and the list goes on... Unless you detail out the current bike's spec & condition might find hard to guess what is wrong.

+100 to Sri, @ Nilay, adding to what Sri has said, Just give me answer to one question. Where is the 3KA20 Bore from? Asking this because this will give you elaborate answers to most of the problems faced. I'm sure most of the seniors will agree to this too...

Assuming the carburetor and reed valve had not been tampered with, check your Ignition timing with strobe.Check also the port timing of new bore with the stock/old bore
