Very well said, can you make a video to identify original piston vs duplicate piston. I brought a 1mm Goetze piston for Rx100 but it looks cheap and doesn’t have “goetze” print inside the piston whereas my old Goetze 1mm piston does have it
Sure
Very informative sir !!!!
Haven't seen any video on RUclips regarding this topic... Keep making such Informative videos on topics which are not yet explored...
Appreciate your work always ....all the best for 1000 sub mark!!!!😄😄😄
Rajas Gadkari man I really appreciate you stopping by, remember you are the sole reason I am here, if only I could match your video quality 😂

Superb video dude,too the point.Just what i was searching for my rx
Slimline Customs 👍
One more thing , when should i need to replace the carb
And what is good
Changing carb or replacement of jets and all kit..?
The carb is never really a consumable item, there are rebuild kits available that can take it to prime condition
4:30 Brother, I was told that the rings should not move freely in 2 stroke pistons and if it is 4 strokes, it doesn't matter whether they move freely or not.
Not clear on your question
@@Yamakaze At 4:30 mark, you were saying that the piston rings should move freely around the piston. I saw few other videos where they were saying that, in 2 stroke bikes, the piston rings should not move around freely in the groove and the piston-pin notch is there to prevent that from happening.
@@mjshaheed that’s true. It won’t move freely. Maybe a mistake
@@mjshaheed now I remember what I meant, it will spread out and form a tight seal around the piston and helps keeping the charge sealed in the combustion chamber. It won’t move around but it will spread out
@@Yamakaze Thank you so much for taking time to explain it ❤️
I own a shogun i wanted to know whether i should install sleeve in my bike or no its is cutrently running on 1mm piston. Will the sleeve decrease my power or are these just rumours??
Sleeve will decrease the power
My bike rx135....starts without choke..power is also good...but piston is making knocking sound due to usage without 2T oil in d past....should I go for oversize rings or boring ???
Replied
Very unique info. on the piston-rings-cylinder diagnostics. 👌
My Rx135 is in storage in outdoors for the past 5 years.
Now, I have been able to get hands on taking stock of the condition and revamping slowly. As expected the engine is in seizure. I removed the head to see the condition, and to my surprise, I see some kind of scaling and deposits on the cylinder wall, giving it a scotchbrite kind of surface. It has hardened. I could see this as the piston has settled at the BDC.
I am concerned and trying to understand about this condition of the cylinder.
As kerosene is not available, is it a good idea to pour some 2T oil or diesel into the cylinder and leave it for some days?
I had sprayed WD-40 two days back via. the spark plug hole to see if it can loosen. Only then, I have removed the head. I have dipped the cyl. head in diesel for general cleaning and hoping to dislodge the carbon in combustion chamber of the head.
The bike is 22 years old but run less than 20k.
Request your guidance for saving the cylinder. Thanks
Use a a wire brush for cleaning the head
@@Yamakaze Thanks for the reply. Head is no problem. It got cleaned with WD-40 and diesel and some light brushing.
The problem is with the cylinder wall where some crystal kind of deposits have accumulated. I see a direct contrast.... the cylinder wall is supposed to be the smoothest surface, where as right now it appears like the roughest sandpaper is stuck on the cylinder wall. 😊
I have been spraying WD-40 on the cylinder wall and then soaking a cloth in diesel and forcing it in the cylinder, so that diesel keeps dripping on the scaled surface. I shall observe and keep pouring diesel every alternate day for next 1 week and see the changes.
Any better method you suggest could help save the cylinder.
Thank you very much.
@@vintubeable it’s the rings which are stuck, if the sand paper like surface is present then it’s better to break re it to next size
@@Yamakaze Quite possible. I shall know once it frees up from the seizure.I am working towards it. Thanks for the guidance.
Can you help...my RxZ producing ring bell sound ..the experts said that the piston should change ....what is the Hiden info on that sound ..can you tell the whole rate for repairing it ...what should do for that....
check the compression and if its low then take the piston out to look if there is excessive scoring. Price depends on your mechanic, the sound could be bearings, clutch bell or even the crank.
Bro when we do a rebore does polishing the whole piston and the cylinder bore make any perfomance
Nope
Hai. Could you please tell me which other piston suits Suzuki Shaolin to get more power. Or would it be ok to bore the existing one
There is no piston that increase power, what do you mean by boring the existing one?
Hai, too much white smoke coming. Either I have to re bore or to buy a new one. If I have to buy a new one, which one should I buy in case if I don’t find Shaolin piston. Any other models piston suits?
Thanks
@@joshymathew876 white smoke in a 2stroke is not because of bad rings, that's 4 stroke, if the gear oil leaks into the combustion chamber this can happen.
Hai bro my Rxz Previous owner has bored it to 0.25 oversize and has used the std stock piston since it was in good condition now I am not getting the compression or the power generation, can I use a 0.25 oversize now without reboring it to 0.50? Pls reply me bro and mechanic checked and told the bore is in excellent condition on 0.25 oversize without any damages or scratches inside.
Put a .25 piston without rings and check, it should be slightly tight, if that’s the case you can install the .25 piston. You should never install a standard piston in a .25 bore
Very informative vedio bro ...keep going...save tow stroke 😎🤩🤩
arun kannan glad you found it informative
Very detailed description..... Good 👍
👍
Brother please do a video about all the RX models, 5 speed conversions, different models, how to find which model is which year from the serial number. And mainly what to look when buying a used one. I know I am demanding a lot, but I can't find reliable information anywhere else.
Let me try, i don't think one video will be able to do justice to this lengthy topic you asked me to cover. Thanks for subscribing
@@Yamakaze Your content is top notch, Thank you! A what to look for while buying a RX 135 would be really appreciated, because I am planning to pick up one.
Faizu Salim don’t worry, there are tons of content available, it’s just discrete. you can reach out to me for any questions through the Facebook fan page or instagram, details are on the home page of this channel
Bro eingen jerking rx135
While slowing the speed
Pat pat issue
Not smoothly throttling down
Please give me solution
Could be electrical, which year and model?
@@Yamakaze 1999 rx135 bro
Unsleeved .5 running
Changed cdi swiss to Nippon
Changed spark plug 2 times tried bosch and ngk
But still same issue
Also changed Reed valve HTA
Bike acceleration up is smooth
@@Yamakaze also i have changed the pickup coil brother
@@baljeetsandhu2049 if possible try swapping the carb with a bike that is working well
very clear thanks for the info
👍
How to check if the cylinder is bored properly??? How much gap should be there between two end's of rings after rebore if we insert ring without piston??
That’s not how you calculate the clearance. You will have to measure with the rings on the pistons. The factory recommended clearance for Yamaha and Suzuki bikes is 30 microns
My piston is making noise...should I check d piston condition n then decide to go for oversize piston rings ???
Yes
Really very helpful video I have got on RUclips after long time, Good job 👌👍.
I'm having yamaha rx 100, but the problem is I need to give choke for starting the bike every time and even I have noticed Extra white smoke is coming out of the bike.
I have done the complete engine work before the lockdown (engine rebore, changed piston, changed the bearing).
Could you please help me out? I'm assuming the fraud mechanic just fooled me.
JFYI I'm have maintained the speed 40 km per hr for riding purpose. White smoke which I have noticed. In 200 ml of petrol without 2t oil & the oil pump isn't working.
if a bike doesn't start on a warm engine without choke the pilot circuit is blocked, clean the carburettor and also make sure there is no rust in the petrol tank, replace the fuel filter after rinsing the tank if rust is there.
@@Yamakaze thanks for the reply really appreciated.
Bike gets start in the warm engine and petrol tank is little bit rusty. Could you please help me out with the white smoke problem?
@@amanmahajan9234 White some means that you are burning the gear oil, white smoke is not to be confused with the blueish smoke that is a two stroke signature, some 2T oils produce more white than blue smoke. first thing to do is check the quantity of the 2T oil, max amount of oil should be around 30ml per litre of petrol. if that doesn't solve your problem than you need to see if real oil is shaping through into the combustion chamber. that would mean bad oil seals or worst, damaged crank case.
@@Yamakaze Thank you very very much ♥️
Thank you so much, Sir!!!
Some noise , something like by some loosen parts, comes out from the piston portion of my 93 modl rx100, for about 3 years. I did not open the head. Is that due to a damaged piston ring or so ?. I do not feel any power problem, but the bike does not give the crystal RX rin.tin.tin sound. Do I need to go for a ring change ?
Army Josh might be a bad top end bearing, it won’t be wise to just change the top end bearing, you need to change the other bearings as well, I am pretty sure that your crank will have play. You are looking at a overall engine rebuild.
Army Josh the top end bearing is a few 100 rs, change it if that’s bad. It’s worth a try at least
@@Yamakaze OK..will go for it.
I own a suzuki samurai. It is clocked around 80k kms. And havent done rebore till now. It is in std size. And bike doesnt idle well. It over accelerates when I start the engine. And stalls soon as I ride and stop.bad mileage. It is giving me around 10-18kmpl. And also it is not a constant mileage. Previously like last year it was in same condition but some what better, during those days it gave me around 40 kmpl. Exhaust was in good condition in those days. now there is not catalytic converter in it. Each and every time oil is dripping on the floor which is in pure black and thick in state. when i ride or else when i accelerate it hard it drips oil like hell on too the floor. Too much oil in exhaust.
This is my bike's condition. Please help me.
Can it be solved by replacing piston. Or else does it need a rebore.
Please help.
Sai Yasaswi the revving is not piston related, you either have a vacuum leak or your throttle cable is stuck
Very helpful
Glad to hear that
Bro..my piston is producing a lots of sound..so i decided to rebore my cylinder and add a oversize piston..at currently my piston size is .75mm and iam reboring it to 1.00mm..so will it decrease my mileage to a large variation..my bike is yamaha rx 100
It won’t cause a big impact but do the run in period perfectly
@@Yamakaze thank you
👍
Very useful...
Glad to hear that
Will i have to ride below 40 to 50 kmph if i change piston rings?
For 1500kms
@@Yamakaze i didn't change piston i just changed piston rings.
@@Shriram_767 200-300kms
Sir I want some information regarding Shogun sir so please , So how can I get help from u......

Wich brand piston r gud?
Art
Sir I installed new piston connecting rod and also piston bearing, connecting rod pin and it's bearing but after I start bike rx 100 I hear a Noisy sound,I think piston sound,so brother how to do please help 😥
Take it up a mechanic and find the source of the sound
How come we know that we reached the time of a rebore other than piston or rings sound? Is milage drop be a reason of rebore
Piston slap, loss of compression, mileage drop
