PART 2: My Lockdown Project - Rebuilding A Classic Aprilia RS125 Two Stroke 1999 Restoration

[@boneav83]

You are 100% right to be doing this. I bought an RS last week, 20 years after buying my first.

[@samu5167]

I just bought an used Aprilia rs 125 2007. I want to get it as tiptop shame as i can but I don't know wtf I am supposed to do. Thank you for these videos. They are definitely underrated

[@boddisonsdelcolservices796]

I’m currently doing the exact same thing restoring my 2001 rs 125 fp, really looking forward to seeing more from you on here and in the aprilia group👍🏼

[@magnuspersson2080]

I have one but it’s a year 2000, restoring it and making it shine here from Sweden

[@letsreviewit8925]

Good luck to you, its rewarding but costly. Definitely a labour of love!

[@m7jnu]

Epic rebuild, I had a nice RS250 back in the day!

[@trianedtog0417]

Want one now

[@letsreviewit8925]

I loved the 250 but so rare now

[@mitorider1365]

Great stuff so far, Keep up the good work.

[@MRryuhayabusa]

Great job mate!!! I thought u were a really established youtuber because of the quality of your vids. But im suprised that you dont have a significant amount of subscribers. You deserve more views for the quality of your vids!! Keep it up

[@letsreviewit8925]

We're getting there! Thanks for watching... :)

[@MRVW-32]

I know how you feel. I have build series for a rs on my chanel but it was just ment to be a quick fix and sell but i fully restored it and painted it midnight purple. Its hard to stop when you start. Great video dude be nice to see you do some of the work

[@letsreviewit8925]

Good luck with the build dude!

Awesome video man!

great job

[@anttihelin8820]

Nice! Have you noticed that air intake rubber twin pipe has smaller ports at round shape heads and bigger at other side ports. I tried both ways and I considered the round shape pipes in the airbox, while bigger will stay outside. Reason for the decision is that it actually was somehow better while bigger ports were at outside. I figured out that if the flowth will accelerate in smaller round shape tubes and even produce somekind of small hurricane, it's just better like that. I even tried to inhale trough the both sides and I found it easier to breath while I inhaled trought the round shape. So it's somekind of funnel or even diode -shape. I would say bigger ports does collect air better, so maybe you would like to try it so also, thanks!

[@mrjaos521]

😀😀😀 great job 👍

[@tobyreynolds2941]

Just as I noticed during disassembly of your footrests the chain roller on the brake side is buggered and the exhaust rubber hanger on the left hand side. But nice to see someone trying to do it properly

[@steven-vn9ui]

Why not just slightly crimp that stretched spade connector for the water temp sensor? Best to avoid cutting the loom if you can bud.

[@flanno9]

thats what i do. it just gets loose over time. i just squeeze it down with pliers.

[@xtreamersm1575]

I was fuming at that point..... screaming just squish the sides down....

[@steven-vn9ui]

@@xtreamersm1575 Great minds.....

[@katywalker8322]

Even worse when replaced with a pre insulated connector!

[@13thdukeofwybourne69]

@@katywalker8322 Agreed! great series of vids but I properly cringed at this bit.

[@katywalker8322]

Big problem with adjusting the lever pin so it is too deep is that it slightly preloads the piston, but by doing so blocks the hole from the reservoir into the master cylinder. So as you use the brakes and the pads wear, fluid can’t get into the system to take up the volume. So you soon land up with no brakes.

[@martinsliepins6225]

i couldnt understand why the temp sensor was going all over the place on mine a while ago, and i found that i had the same problem on the temp sensor as you, seems like its not as odd as i thought

[@harrykingsford-smith609]

ive recently bought a 2002 aprilia RS50 for my first bike and i was wondering if i need to premix the oil in to the fuel or not whenever i fill up

[@letsreviewit8925]

I’m not sure why people run premix it’s a pain in the ass! Haha

[@tobyh4862]

I just bought a 2000 rs125 harada edition!!

[@shellisturbo]

The gear lever has another pin that secures it to avoid it accidently being removed. The securing pins not listed as a separate part and barely appears on the part schematics, with the way everything wears on these bikes your probably best ordering a new ball joint.

[@letsreviewit8925]

Probably going to replace the whole gear linkage 😬

[@flanno9]

is the exhaust mount right, where it joins the frame? (where left hand footrest was). it looks strange.its like theirs something missing.

[@letsreviewit8925]

Correct - its been partially disassembled - i have all the parts waiting to go back on, thanks for watching.

[@harryoliver6650]

What size watt and ohm relays did you put in for the led indicators a because I bought the same ones and have the same problem thanks

[@letsreviewit8925]

Harry Oliver not sure but the ones I’m using are R&G generic ones I got on eBay www.ebay.co.uk/itm/233103769895 once wired in they work perfectly though my bike was missing an earth which also had an impact instead of flashing they stayed on

[@qubitser]

How is the vertical play in the footsteps (and levers )

[@letsreviewit8925]

No play in the levers but the foot rests are quite bad

[@trianedtog0417]

Nice job make sure thermostat works or take it out

[@letsreviewit8925]

The thermostat works, it just had a bad connection - thanks for watching

[@flanno9]

@@letsreviewit8925 the connector just gets loose over time from the vibrations. i just squeeze it down with pliers. goes bk on a treat.

[@ashleighharris2357]

Have you done a compression test to see if he needs are you building

[@letsreviewit8925]

Hi Ashleigh, the engine seems to have been rebuilt but its running rich so i'm going to take a look over the carbs.

[@deanoricemusic1309]

Good videos dude, I have recently started the same project on a 1995 rs 125, just wondering where you find the parts? Is there a company you know of? or is it a case of just searching high and low for parts? Cheers

[@letsreviewit8925]

I tend to source them from different places PJME are good for engine parts and accessories, www.apriliagenuineparts.co.uk/ are good for genuine and you can't beat forums and eBay - good luck with the build mate

[@deanoricemusic1309]

Excellent, cheers dude 👍

[@BigBadSupaHero]

What did you use to polish the frame? Keep the vids coming 🙂👍

[@letsreviewit8925]

As you can see in the vid just a compound metal polish and two grades of polishing wheels with a drill. Takes some time but looks amazing

I am restoring my 2001 rs125,gearbox is stuck in 4th gear,and it needs a lot of work...I bought it neglected like that

Hi mate have you still got the wiring diagram ?

[@letsreviewit8925]

Should do, what model have you got?

[@malinjones6815]

There’s supost to be a clip that goes thru the hole on the ball joint

Thanks Malin, I saw that in the manual - another thing to order!

Your clutch cable is routed wrong should go through the other hole in the frame

David Bates thanks I ordered a workshop manual weeks ago and it still hasn’t arrived so I’ll be checking all these things before reassembly

How much did u pay for this bike

[@torhalle1926]

Got three now. 2004-2007. My experience is that the electrical is poor quality. Gearboxes are easily worn out. to bad the cylinder is nikasil: expensive. Plastic parts are hard to get. Aftermarket often poor quality. That is all forgotten while riding the rocket.... 🙂

Hi i am doing a rs125 rebuild that came in boxes, struggling to find a decent pic of rear brake hose routing. does it go round the pivot of the swing arm and down the underside of swing arm to rear calliper ?

[@letsreviewit8925]

It dips down behind the footrest and runs along the underside of the swing arm. I’ll see if I can find a pic

[@letsreviewit8925]

Drop us a message on the Facebook page and I’ll send you a pic

[@gtisid]

Lets Review It thanks i’ll take a look i think i understand as i have seen a small pic rather than go over swing arm keep it outside the frame and between the footrest bracket . that makes more sense . probably have a hundred more questions as it’s like doing a jigsaw with the wrong picture on the box! a 95 rotax 123
