Restoration of an abandoned Aprilia RS125 barn find forgotten since 2011 

the best thing for grips is hair spray , slides on easily and sticks like glue once it dry's off.

The RS125 was my dream bike as a 17yr old, couldn’t afford the £3k+ at the time for one. I think we all have the 500g tub of red grease, I think mine is about 20 yrs old now. Lost count of how many calipers I’ve rebuilt now 😂

Try hair spray for grips in future. Old BMX'er trick. Lubricates whilst it's wet but dries like glue very quickly 👌🏻

Internal combustion engines love cold/cool air, your mod sounds like a good idea.

HRC did pressurined air boxes for the NSR250 where the carb was inside the airbox to equalise the float bowl pressure. Would be alot of work but not impossible 😂

I love this series 👍

Mr.Muscle not recommanded on alluminiun after readding instructions, I Know a channel like you in USA call CJ media who restore motorcycles and He always used the product Super clean for parts. Always cool video thanks

Great video mate keep up the good content.

They are mate i love his attention to detail and the research hes goes through to make sure hes doing everything iff not better than bmw did i could watch hours of his videos 😎👌

Great job 😊

Great stuff, really enjoying your vlogs. It's a good idea with the air intake. Give it a crack and see how it goes.love it

Zep citrus degreaser - best cleaner I’ve found for anything oily. And for restoring yellowed plastic back to white I think you were getting at hydrogen peroxide, it’s a hair bleaching cream, also it on in a plastic bag and then pop it under a UV lamp

Great vid

My very first big was an RS50 and it'd already been tweaked so I could easily get over 60mph. I had that for almost 2yrs and wanted to get the RS250 but I could of gotten a much more practical bike for the same price and it'd have extra power n be fuel injected. The place where I got all my bits they were trying to sell me a brand new Aprilia RSV1000 n I was only 17. Obviously they'd restrict it but you have NO IDEA how close I was to pulling the trigger and buying it on finance because it was just so beautiful and it still is to this day. This was back in 2005 btw. I would love to buy another one but I had a life changing bike accident which took my left leg off up to the groin and I can't even wear a prosthetic as my pelvis was smashed to bit's. I was extremely lucky to be alive but thinking about it. I really wish I'd of just bleed out on the scene as I would of died doing something I absolutely loved! 😪 FML That was over 10yrs ago and I still haven't been able to find a job because of my crippling pain and phantom pain which I'll have for the rest of my life and there's not much anyone can do apart from just giving me pain killers which does help but it's not fixing the problem as the NHS don't have any money to help people once you've been discharged from hospital.

Hi mate. When you fit the grip, use the air compressor with the normal nozel, put it between the grip and the tube/bar, spray the air and slide it on. It will take two seconds and your need no lube. 😊

I used some warm water, nothing else went straight on, did it to the Gilera not two days ago, (has the same handlebar as the Aprilia)

To take that part off mine I had to take the exhaust off first as it goes up through the rear swing arm through the tail section, dirty (greying) plastics. And fix any electrical wiring whilst I’m there, I’m doing the same thing to my sc125 can’t wait to get her road worthy

Yes if you go premix, you would need to increase the jetting. It sounds strange but adding more oil will make it run leaner as the oil takes up some of the petrol volume.

washing up liquid to lube your grips on, goes on slippery and then dries like glue also citrus orange degreaser for stubborn oil and grease works well.

That piece with the crack in i snapped clean off when i came off once :(, fortunately other than that and some scratches not much else damaged.

Over cleaner is only any good on raw aluminium… used it for years on go kart engines and it worked fantastically!

keep up the great contents you doing great job mate ps that oven cleaner works great on my oven i use same stuff so keep that just for your oven 😄

A trick i use for the bike grips is alcool and/or air compressed: alcool makes the job very easy, and evaporates itself. If you don't have alcool just use air compressed: the thin air layer sprayed while mounting the grip will help you quite a lot. Try it and let me know :) cheers from italy!

Yes mate best place for it 😂😂 you need to invest in one of them ultra sonic cleaners 😁👍

Pah! You've barely started with that pot of grease! I've just about finished my pot of the same stuff, it took me about 30 years 😀 I've always fancied the idea of slapping a big 4T MX engine in a little bike like the RS. Perhaps once the 125 engine has had enough you could try it and let us know how it goes. RS450 anyone?

Harpic x 10 removes rust and cleans up metal like new. Leave it to soak for ten minutes

Looking forward to this one progressing new sub

Nice bike

Really enjoying this - thank you. I think you said that this is going to be a track bike - in which case, maybe worth considering fitting sintered pads instead of those organic pads?

Really surprised mr muscle didnt clean those rear sets up as i used it to clean out my clogged alloy inlet manifold on my diesel van a few years back and it came up like new, unless theyve taken out the good stuff since then 😂

I also want one but never got round to getting one its when i start watching m539 restorations it sets me off 🤣🤣

I'm sure the one I had did have ducting to the box, but this was a while back

Use paraffin to clean up all those greasy old parts very effective

we used to use furniture polish ,pledge and the like for cleaning wheels ,then again dont know if you can still get it now

19:22 Peroxide, is the word your looking for.

Aprilia on the AF1 Futura used a pipe for cool air from the fairing, past the engine through a plastic sheet and to the area of the airbox intake. They didn’t bother with the RS125 Check if your cdi has been modified. As standard between 4750rpm and 6000rpm there is a massive amount of ignition retard which causes a flat spot (presume the aim is to make it easy to get through homologation tests). The cdi can normally be modified to switch to a better ignition timing map - you cut into the cdi at a specific point to cut a bridge on the circuit board inside. If you are doing without lights, etc, the probably easiest to make a new loom from scratch. Easy enough. Bleeding the rear brake can be a pain. The bleed nipple is not at the highest point of the caliper when mounted on the bike. Aprilia used both Brembo or Grimeca calipers (front is Grimeca but badged Aprilia), and various Italian bike specialists should be able to supply pins, etc, for the calipers. Baby wipes are convenient for cleaning a lot of rubbish off the wheels. Before now when the locating pin on switchgear is damaged I have replaced it with a small metal rod stuck in place with Araldite (mind you, I have also helicoiled the plastic thread in the switchgear for the bolts that hold it together)

the left footrest bracket is heavily bent inwards buddy.

You don’t need brake light for daytime MOT ? Never knew that

Try not to delay too much for the next episode! :)

Where do you get all your missing screws and bits & bobs ect?

Even a daytime MOT still needs a working brake light surely?

time for you to get a parts cleaner and an ultrasonic bath

Diesel fuel is a great cleaner, too

Are you selling this bike at the end

Never , Never order parts that have to come direct from Italy during September ( i think they take the whole month off !!! )

Compressed air from a blow gun between the grip and the throttle tube/handle bar and just slide them on, thank me later 👍😂😂

19:21 Hydrogen Peroxide.

Standard Brake fluid (DOT3 or DOT4) is Alcohol based, DOT5 brake fluid is Silicone based - NEITHER work with or should be ANYWHERE around red Axle bearing grease, whether it's oil based grease or Synthetic - They make Brake assembly lube if you must, but using brake fluid as assembly lube on braking parts is best - That red grease could cause your rubber piston seals to swell, or turn gummy, or any other number of death-causing problems- the type of rubber they use around BRAKE FLUID is sometimes very weakened around petroleum based stuff- Nasty bit of advise you're posting on the You Tube there sir, as if you know anything?

FYI the music in videos is not entertaining infact its annoying 😒 very annoying

Speak with your local valeting chemical rep. Someone like AutoSmart. Buy some heavy duty wheel cleaner and it will save you so much time (read the label and ask the reps advice as it is aggressive on your skin, eye, throat).
