Hi Tom this Andi from Germany 🇩🇪 very nice video again you have done 👍👍👍 great job 👏 ! But remember the spark plug BR8ES and BR9EG is for the restricted 80km/m and 11kW version of the Aprilia RS 125 the non restricted 22kW needs the BR10EG!!! If you drive wide open with the smaller heat rated spark plugs you might burn a hole in the piston. Continue with your great videos! You doing a good job 👍!!!

Change the 30hp cdi to the 15 hp cdi. The problem will almost disapear. They did this to get better emissions. This is since the rotax 122 engines. The 123 does not have this problem at all, because it has a different cdi system. The cdi should be located under the passenger seat.

Hello Tom, I think that the correct procedure for the plug chop is grabbing the clutch lever and stopping the engine with the red switch, and while the engine is at 0 rpm then stopping the bike and checking the plug. When engine is not stopped immediately, as in the video, the reading is not accurate.

Tom, I have so many things I want to tell you about your RS in general after watching a few episodes, but honestly I'd rather start by two things: 1. The mod you did to the GoPro for the audio is better indeed than the GoPro Mod, the Mod has a very weird sound profile capture, it does not really pick up in the same strength the same frequencies the human ear does. Yet, after a LOT of testing on this particular subject, I 100% guarantee to you that what works better is a full body thick sponge case for the GoPro. Amazon is flooded with them. Don't cheap out too much, they're fragile in nature, but also don't spend 10€ each like I do because of the same reason. 2. I find that based on what you show us on the videos, the commuting and so, your tune of the bike in general is really opposite to what you want. You're getting a lot of things done that increase top range performance in clear detriment of the medium and lower range. The exhaust is a good example. For how you ride around, the stock one would suit you much better. This carburetor follows the same line. I'm not here for long enough to really know if you've explained these topics in a video, I'm guilty of having skipped bits here and there. So maybe there's a reason for it? Either way, I like both how you do your content and how you approach the tuning on the bike. Love how you dig into technical details and so on. Keep it going
@tomdidit4216

Hi and thanks for the large comment. 1. I have seen this mod tested on the GoPro. Taking onboard your advice, I will be sure to buy the more expensive foam covers from Amazon👍. 2. I agree. It’s very hard to tune these 125 bikes to perform well throughout low, mid & high rpm’s. The work I have done has noticeably increased the top end performance. As the Aprilia is in such good condition I plan to stop riding it around the city as start using it for longer more leisurely trips (as intended). My Honda will be used around the city👍 Thanks again for leaving a comment and sharing your advice. Cheers Tom

Hello and thanks for the video! I have the 1998 model of the rs 125, the racing replica extrema model, with the same 34mm carb. I was just wondering where you get your parts from? I cant seem to really find any spare parts online and i need to do some tuning on my carb as it completely loses power on full throttle and cant go past 9000rpm without bogging out and it does the same mid range bogging as yours did when it was running too rich. The previous owner removed the original air filter box and fitted a completely open K&N filter, and i suspect that he just put on a way too big main jet because it is running really rich right now.

Greeting Ian Firstly thank you for your message - and my apologies for the late response. I have been away for a few days. The de-restricted Aprilia really does fly for a 125. Luckily I found this bike was well looked after with low KMs. I own this bike because I’m reliving my youth. These were the “bike to own” when I was 16-17 years old in the UK. Plus I’ve only owned 2 strokes….😎 These bikes were developed on the track and honestly, does not suit my inner city traffic commuting. That said, I still love it. I do plan on taking a few road trips around Australia one day, but it’ll have to wait until I get a sports tourer (or something bigger). Are you a bike rider? Cheers Tom👍

Hi! We started to tune with your setup. Fixed the needle valve, closes correctly, but with the 160 main jet the air screw did nothing. We put back the 148 but it still does nothing. When we close the fuel tap after a minute it starts to run lean, then it revs with the air screw. Now, we know it melts the bike so that's not the way to try. We had a very dark brown spark plug, we've been told to lower even the 148 jet. The pilot jet was B36 changed to B35, seem okay. We were trying to mess with the float level, with your measurement it was less than 14. We've been told that hold the carb upside down, release the float and let it settle by gravity, then from the gasket surface it must be 11mm. Our is slightly bigger now. What should we try, and I can't understand how the hell could you set your bike up with these parts?

I also experienced difficulty with the float level. This was causing me massive difficulties. Make sure the float is not sticking inside the bowl and causing overflow/flooding. My current settings are -B36 pilot -Thick needle top clip -And 150 main jet. Do you have a new carb or an old carb that is restored like mine?

In hungary the spring is starting, I'm usually tuning and riding in 20°C. You need the bigger idle jet and I think the bigger main too because the air contains less oxygen in Australia?

In your case: Maybe try adjusting the needle position. Moving the needle up, by lowering the C-clip will (safely) richen the mixture. Go for a test ride and see if there is any improvement. If it is worse, then try to lean the mixture bu adjusting the needle in the opposite direction. Good luck! T

I’ve personally never rode an RS250, however I’ve heard they go surprisingly well… If I decide to sell, I’ll be sure to drop you a line👍 Cheers Tom

Hi Tom. Have you got the latter bike with the piaggio ecu or the earlier Nippon denso? I heard the later bikes have electronic restrictions and a catalytic converter? What are your thoughts?

Hi Ametti To be honest I’ve not checked my ECU. The last owner told me the Arrow exhaust and ECU came restricted as standard. But I am unsure of this.👍

Candle br8es? In my aprilia sx 125 (rotax 122) have br9es. You know the difference?
@tomdidit4216
Жыл бұрын
Hello there Enrico In summary - operating temperature. The BR8ES is hot, the 9ES is cooler and the 10ES (or equivalent) burns even cooler. The 10 works well at high RPMs and racing conditions. As I understand, they are all suitable for the rotax 122, depending on your tuning and riding conditions👍. Cheers Tom

Hello Tan Thank you for your message. There main difference here is the 2 stroke engine and the 4 stroke engine. There are videos on YT that explain the main differences (if you are interested)👍 Long story short, small capacity 2 stroke engines will often outperform the 4 stroke equivalent. My bike in the video has a somewhat “tuned” engine. To answer your questions- I don’t think the newer RS4 motor can match the performance of the older RS without spending big money. That said, the RS4 is still a great bike for twisting roads etc etc👍👍 Hope this helps Cheers Tom

Hi great video. Could you help with this at all. Bought an Aprilia it has a full arrow exhaust on it and 34mm carb it’s a 2001 rs. It will idle fine but when riding on brake ing it cuts out. It will also do this sometimes when releasing choke and go to rev it will die. Any help would be highly appreciated

Hi. What filter do you use? Thanks. I have a rs140 with 40hp at wheel with "hartruson" intake on standard airbox and I believe I have lack of air 😕 and there is almost no sound from intake...for me it is also very important 🙂🚀

Hello Markuss. I would listen to the engine. It may ping if the mixture becomes too lean. Also, with the bike hot, replace your spark plug with new and check after 10 mins of riding. The colour of the new plug will indicate what’s happening inside the engine. There are plenty of pictures online of what a 2 stroke spark plug should look like (with good mixture). Cheers pal

Any recommendations for a main jet for 34 VSBH with a gianelli exhaust. Original cilinder, intake etc. It rides not bad, its not bogging or anything. But I am just curious if it can get any better. I am currently rebuilding my engine. Greetings from Holland 🇳🇱

Hey so I'm 16 and currently have a moped but I'm getting a 125 in a few months as I turn 17 (A1 restrictions in UK) and I'm a bit unsure what to get because basically all top line 125cc are the same for example yamaha mt 125 and yamaha yzf r125 have the same acceleration and same top speed even with how different the style of bike they are. So I was looking to get a honda cb 125r however the aprilia rs 125 is the only 125cc bike that i know of that changes the game due to it being two stroke My question is that, is it really hard to maintain an rs 125, is it legal for A1 use as it has way more horsepower, just general comparison Because I would love something with more power however I don't know if there is drawbacks I hope you see this as I'm dying trying to figure this all out😂 My moped is 4 stroke so I have no idea about 2 stroke engines

Greeting Ellis. Thanks for your message - I hope my response finds you well. When Aprilia RS came out I was 16. It was a dream bike for me, however I could never afford one. I’m 39 now and had to get one. They are so much fun! Understanding your current situation, if you are after extra power and some fun, there is nothing like a good running 2 stroke (in my opinion). Of course, extra power comes extra maintenance. The Yamaha YZF125R and Honda would also be fun, reliable and make a great commuting bike due to the fact it is using modern 4 stroke technology etc etc. It’s an exciting time for you. Wishing you good luck with the decision you make👍. Regards Tom

What notch is your clip on for the needle in your carb? And what are you running for air box / filter?
@tomdidit4216
11 ай бұрын
In my case, the problem you describe was caused by a rich condition (too much fuel in midrange) as the needle controls the midrange, I use a thicker needle to lean the mixture. First try adjusting the clip on your existing needle to see is the issue improves. You may need to change the needle.
