Never mind I saw the answer down below on another comment.

I was all by myself in my student room, problem solved ;)

It may work with gluten-free bread, but it is better with normal bread, because gluten make cohesion in bread

@@romainquiban5469 do you have any experience with replacing your bearings with Polyamide cage bearings? It's a little more expensive but should make running noise Lowe

@@Tiwey I never tried, I’m curious to know if it really reduces noises

@@romainquiban5469 I will try them out. If there is a noticeable difference, I will come back to you. There are sadly no reports or reviews of these bearings. They seem great. I learned that changing the piston needle bearing to Polyamide already reduces vibrations

Hi, measurand between: - 66.72 - 66.92 mm need 0.2 mm washer - 66.93 - 67.06 mm don't need washer postimg.cc/64G3295r Normally, if neither housing, shaft or con rod have been replaced you don't need to change washer

@@romainquiban5469 thanks👌🏻

@@romainquiban5469 where are you from?

@@LNH3 from france, used to ride this bike around Nantes

@@romainquiban5469 that it is normal that l can put the bearing on the clutch side on the vibrator without heating à little even remise it and put it back unlike the one on the ignition side Which one put on it longer goatee . Text photo for translation

I think i kept the same rings

Oh 👍 Do you know what a good squish measurement is. Also a good compression limit on a piston?

Hi, the other extremity of this tube goes into the protective cover of the pinion sprocket. Actually I don’t know the purpose of this connection between sprocket and flywheel housing. I’ll be happy to know it

@Paul Mickiewicz hey thanks for this information, good to know ;) oil on rear tyre.. doesn’t seem great !

it should be quicker indeed :D

Bread works too

Hi, what do you call Perspex wedges ?

Romain Quiban I mean the acrylic, plexiglass type wedges and bearing faces you used in these videos. What thickness did you use for yours? And do you still have all these bits like the metal plates etc

@@sparkxx64 Ah you don't talk about this specific video ! I think the thickness of plexiglas plate is 5mm. Yes I still have the specific extracting tools, but I can't take measurements if it's what you want because they are in a different city that the one I'm living now. Chears

Romain Quiban I was actually going to ask if you’d sell them to me and ship to UK?

@sparkxx64 no I keep it :) but you can ask to small metal milling company, they may be happy to do it for you at a good price

I didn’t soak it, it’s bread that I have previously used for others blind bearings removal. So it seems wet because of the residual oil in the bearings !

Thanks :)

I’m not sure I understand. You don’t need to remove the crankshaft nor the conrod to replace your piston and cylinder

Romain Quiban forgot to say, it’s seized 😂

Romain Quiban I forgot**

Klawz ah okay, well theoretically you cannot remove the crankshaft before removing the cylinder. It’s because you have to split the crankcase to reach the crankshaft and both part of the crankcase are linked through the stud bolts that maintain in position the cylinder. Then, maybe you will have to use a grinder to disassemble your cylinder. Good luck ;)

Romain Quiban would you say it’s worth it? The bike is £350 and that’s the only thing wrong with it, was thinking I could lift the cylinder up a bit then put a thick piece of metal in the gap and then hammer the piston down and then repeat until it’s all the way out

it's the rotax 122..

Hey! Yes I was in India. That’s too bad for the Aprilia Rs, maybe it will overheat in India because of high temperature and constant low speed ! :p

Romain Quiban Yeah because, it's a track loving machine. It's doesn't like obstructions or traffic. Do you still have it??? You are from Italy ?? I guess! Hope you enjoyed in India

I had to sold it unfortunately :/ I’m from France, and there is still a bunch of RS. For young people the max cc they can have is 125cc, so this type of powerful moto is what they are looking for

Hi, the lip facing the clutch side like this : postimg.cc/image/9lv4dcqz5/

Romain Quiban thank you, and on the other side?

I think it’s the same, lip facing flywheel side

Yes !

Romain Quiban wow thanks for the quick answer

Yess

Why did you take out the gears? Can i get away with leaving them inside, while replacing crankshaft and its bearings?

I replaced most of the gearbox bearings. But yes I think it’s possible to let them inside while changing crankshaft

How often is it recommended to replace gearbox bearings and how often is it recommended to replace gears and other gearbox components of Aprilia RS 125? Manufacturer recommends engine bottom replacement at 32k km, as far as i know.

Gears are gearbox lifetime except the plastic one for the water pump that you have to change every 16000km. I don’t know about bearings. I replaced them because I could hear noises from gearbox at deceleration.

Well you should measure your squish to know that ;) If you still have the original con rod there is no problem to put the thinner gasket.

its quite late to say it now. but litering out your engine removes the need to check the squish. and its more precise. all you gotta do is calculate the "geometric compression"

I left them one night

Romain Quiban cheers I’m using your video for my engine rebuild. I’m using all koyo bearings wonnser con rod and piston wish me luck haha

Enjoy your rebuild ;) I’m happy to help

It’s just pieces of random cardboard
