Pretty rare to see such a well made review in the scooter scene! Great job, enjoyed watching it! Greetings from Germany! :)
Ahh Thank you Scooter-Attack, we buy the Stage 6 exhaust from you.😉
KAY!??
Bist du es!?
@@alcarez_z Wer sonst? 🤣
Welcher ist jetzt der besser kann nicht gut Englisch
@@stevie9903 er sagt in etwa: der alte kommt aus China und ist eher yasuni c16 Niveau der neue ist ein yasuni R von yasuni also passen die Schalldämpfer von Yasuni in Carbon und Kevlar auf den MK2
That's really interesting. Thanks Brad. 👍
Glad you enjoyed it😁
please make more, love this
Thank you, we try, we just have very little free time🙃
Would be cool to know, how to put together the best parts for the kind of setup that you're looking for, maybe a video on 3 types of setups, Say entry level mods, then mid range setup with a Bbk/exhaust kit etc and then the Ultimate Racing setup, and what you want to look for when buying parts and why you want to buy certain items. Would love to learn more about this!! Great video too Team 💯
Great idea and thanks for comment/watching Deezy👍 We have several videos showing full builds, the Zip build video which represents a good street rider and we have the SR50R with MHR cylinder build. Have you watched these?
@@scooterstreetau might have to check out the Zip build and YesI saw parts of the sr50 build, broooyou guys are craazzzyyy hahaha Love to see it, struggling to find someone locally that does mods 💯

I had the mk1 on my runner. And had a 74cc malossi mhr cilinder. With polini purple springs in the clutch and 3 gram rollers in the vario, and had size 74 in my carb so didnt use alot off fuel but still did 0-130(rpm limiter) in 8 sec.. the Quick release flence is really good because never have breaking bolts on your cilinder
Sounds like great fun..
These thing ran crazy on my nrg 70cc s6 sport cyl too 👌 great times for sure
The Piaggio s6 pro rep...where it bolts to the exhaust port. Its like a cup and cone system. How is one meant to make that not leak. Doesnt matter how i fit it. Oil always leaks between the cylinder and the exhaust. Is there meant to be some sort of gasket there?
Yes I know what you mean but all of the Piag scooters run this exhaust system and the rounded head sits inside the Ex port. Get these two faces to match up first before loading the bolts to the bracket, this will help getting an air tight seal around the contact point of the header. We have some videos on this.
Hey man, im wondering if malossi multivar and malossi clutch with clutchbell with red clutch springs are good with s6 mk2 pro sport and pro replica mk1 and motoforce 24pwk with 94 main jet are good together, or should i buy a new full vario? Also how well they preform together? All those in a yamaha bws 50ac
Hi mate, that sounds like a good little setup. The carb sounds probably too large, we'd normally recommend no larger than a 21ml carb for that setup as it can create a bottleneck at the cylinder and be very hard to tune. The transmission parts will be fine, you just need to fiddle with the rollers to get the weight right, though I would definitely recommend a performance belt.

Im looking for some help with my yamaha jog rr 50cc I've got a stage six pro replica mk1 and a bigger jet derestricted cdi,5.3g rollers, 15% stiffer torque spring and fully stock clutch. The scooter was tuned by the previous owner and had an oversize variator which I replaced because the rollers were worn and I couldn't find any of the same size online. Now heres the problem the fully derestricted scooter can only go 30mph at full throttle and if I have the throttle at 3/4 my speed will drop below 20 I'm not sure what to do don't want to ride on full throttle all the time
First thing you need to check is the main jet. Good chance that its wrong. Its very difficult to diagnose problems when you don't know what the previous owner has done.. I would probably recommend taking it to a workshop, in person it is much easier to diagnose for an experienced technician.
heeey nice channel lots of goid tips

can u recomend an exaust for my setup if posiblle not a very loud one i like deep sound not high pitch one thx.
HI Joc, thanks mate glad to hear form you🙋♂️. From the shop where you bought the above parts, what do they offer in the exhaust range? From what you mention, I would lean towards a standard looking pipe to keep the outlet noise down but still offering a free flow to enhance the performance. Look for brand models such as Malossi Wild Lion orTecnigas silent Pro, others include, Naraku, Turbo kit and Polini. Google these 2 suggestions and then see what your shop has to offer.
Hey man, one question.
I have Stalker with Extra V2 Gianelli, mallosi multivar with 5g rollers, green center spring, blue clutch Polini springs, Malossi air filter and 84 main jet on 17.5mm Weber, it goes about 87 gps speed. Now i have bought Gianelli Rekord, derestricted it, tried with 5 ,4.5 and 4g rollers on same set up and it goes 80 max on gps, even tried original center spring. Can you give mi some advice, what em i doing wrong. Because Rekord should give me better performances in theory.
So if the only part changed was the exhuast, I would have to agree that the exhaust is what has limited the speed. So we look into the exhaust because the Rekord should add small amount of TS. Try the V2 stinger on the record, now test and GPS.
Ok now increase the main jet 2 points and test again..... Get back to us.
@@scooterstreetau yes, just an exhaust and tried 4,5 and 4.5 rollers, tried original central spring, even tried putting airbox and smaller jet on, and it is still worse than Extra V2. With that set up it goes about 87,88 gps on flat. So that means that set up is good. Ill try larger jet and lighter rollers.
@@grgurmandic6622 👍
@@scooterstreetau i tried larger jet, i tried putting air box on, tried with smaller jet, tried original center spring, lighter rollers, everything, and it still performs worse than with Extra.

Hello on Aerox 50 muffler stage 6 mk2 , 17,5 dell orto, multivar malossi and red sponge is it okay?
Sounds good, remember to do a re-tune when making changes to the air/fuel/cylinder/exhaust.
Hey I have a question what size is the spacer for the stage 6 bracket
The spacer to the engine mount seen at 7:17.. 50mm, it can be spaced using washers.
Bought the stage 6 mk1 for my 50cc org and just nugget jets on the carb. It accelerates very slow so my question is if i can somehow balance the exaust with lighter weights and pressure spring and clutch springs?
Just a bigger jet*
Yes you can balance these but the MK1 needs higher RPM to work properly.
@@scooterstreetau so if i change and find the right vario weights and the right clutch spring and right pressure spring my moped will have better acceleration? Or do i need to swap to a bigger carburator and 70cc?
Is there anyone that can help me here you guys helped me last time with my exhaust that I bought my question is I have a Zuma-mbk booster I have a 70cc Athena kit in it aluminum sport kit I'm pretty sure it's a sport kit anyways it's low on compression I thought for sure it had a piston marked A like a fool I didn't tear the motor down to check before I ordered a new piston and ring oem Athena the piston I ordered is the A type piston the original piston has a B on it the cylinder is also Marked B I checked both Pistons with calibers and compared them and they are very close if not identical to each other would it be safe to run the new A type piston it fits like a glove from I can come up with there maybe a 1mm difference in the 2 pistons but they both check out the same with the calipers there both 47.54mm are close I plan to get the cylinder honed out to D glazed
I can't tell you it will be fine, I don't know. I can tell you in cases where a customer was desperate to have their bike back we have used a different size Malossi piston in a cylinder and not had an issue. The difference in the Malossi piston sizes is tiny for the most part, I would assume the same is true with the Athena cylinders. The safe bet would obviously be to order the correct piston.. or confirm the details with Athena.
Is the yasuni R or the stage6 pro replica mk1 better on a original Yamaha aerox?
The Yasuni R is a much safer choice, it will fit nicely and tune up relatively easily on the stock 50cc or 70cc if you go that way later on. The S6 pro rep mk1 is a mid race exhaust, and will be difficult to tune on the stock 50cc cylinder due to the exhaust chamber being designed for a much higher volume of flow. The later S6 pro rep's are made in China, we have seen some quality and fitment issues. I would suggest it is likely the case that S6 have moved to Yasuni manufacturing for the MK2 due to this.
Hi I have recently purchased this exhaust from you and now just fitted it, could use with some advice I have fitted it on with no gasket because it didn’t come with one and I don’t think it needs one from my research however within minutes of riding it had all black melted stuff on end of the exhast under the bike (oil I’m pursuming) is this because I’ve fitted it wrong or is this because I need to up or down jet it. (My bike is a sr50 2016 and it’s stock I belive because it had a standard exhaust on it before and would go 45. Now it goes around 47 on this.
Any idea What should I do to make it not have the oil leak. Thanks
Hey Lewis, It is so IMPORTANT to tune the scooter when fitting an exhaust, this is what our RUclips channel is dedicated to, TUNE the scooter! Find out for sure if it is oil?
@@scooterstreetau yeah it is oil, it’s all on the end of the exhu
@@lewisball7092 Check the oil and fuel system, you may need a mechanic for this one. Did the old exhaust have loads of oil in it?
How come they don’t use a gasket to seal to the cylinder? Would you use any kind of sealant or just go metal to metal and hope for the best?
The Factory exhaust also fitted without gasket. The rounded lip design of the header connection to the cylinder seals as it is tightened. Great idea and one less gasket.
@@scooterstreetau but wouldn't that restrict the flow, given that the header almost goes inside the exhaust port?
@@joaomelo61 It does not go inside, the sealing face is outside the mouth of the exhaust and it aligns with the cylinder not to impede the diameter. Look at 7:09 in the video👍
@@scooterstreetau got it! I though it kind of press fitted inside.
But we should still put some kind of sealant paste / silicone high temp etc right?
@@joaomelo61 no, it's a mechanical seal
Judging by the length difference, i'd assume they have different powerbands? Do you know the powerband of the MK2?
The first pro-replica doesn't like to rev very high like the R1200 for example, maybe 9k rpm.. Curious to know if they made the MK2 to operate at the same rpm.
PS, the polini rubbers for the silencer connection fit it perfectly, i used those when mine ripped. Polinis last longer too.
The pro replica made peak power at 9,500rpm.
The Yasuni R made peak power about the same revs. But it had a far wider power band. Where the pro replica really loses power after 9,750rpm, the Yasuni keeps going. Losing power but nothing like the rate of the replica.
@@paulbudford Thanks a lot for the info!
Mk1 is really good.. mk2 is based on the yasuni and yasuni doenst run great on a gilera runner
Using the Pro Replica MK2 with Sport Pro MK2 @ 10,300 RPM , runs great :)
Hello everyone, tell me where I can find exhaust pipe test charts, I found only old versions, now I'm interested in Léo Vince tt, stage 5 replika MK2 and yasuni r and z, I want to understand which exhaust suits me best, thanks. Piaggio hiper 2 stock engine with dellorto 17.5 carburetor. Thank you
You will find this interesting, www.tuningmatters.com/reviews/exhausts/scooter-tuning-exhaust-test/
For the later exhausts I am not sure.
@scooterstreetau thank you very much for the article, it brought me closer to the choice but it is very old and modern leo vince tt, I guess it is very different from the 2013 version, like stage 6mk2 and technigas q-tre, in your opinion which exhaust is better for stock piaggio cylinder with the subsequent transition to the budget motoforce 70 cc racing cast iron, thanks guys for the help! it so happened that I didn’t ride scooters in Ukraine for more than 10 years and recently arrived in France, and it’s very boring to ride on the factory version :)
@@user-ys2vv2ph3j I like the Yasuni Z for 50-70cc and Yasuni R for 70cc and higher class.
is it necessary to put a bigger carburetor? can i put that exhaust on my original scooter?
No it is not. When you do upgrade the carby you will certainly notice a performance increase..
@@scooterstreetau another question, i found a new yasuni z at 100 euros, does it worth it? is it more appropriate for a 50cc?
@@brighiii The Z is a great exhaust, works well on a 50cc or a basic 70cc build.
Could you make a video derestricting that MK2?
Ah yes, we did one today but never made the video, next time we will make it 🤩.
Can i use my silencer on my mk1 on the mk2 exhaust?
No...the connection is different. MK1 has the rubber boot connection and the MK2 connects straight to the flange. Do a few mods and you should be able to make it fit....
Does the mk2 replica silencer fit the mk1?
Ohh good question, It will fit, but a sleeve will be required to seal the join as you see in the MKI.
Stage 6 pro replica mk2, whit cylinder mk2 yes?
They will work well together. It depends which MKII cylinder, the Sport Pro or Racing. The Pro Rep exhaust will work well with the Sport Pro, however the Racing cylinder will work better with a more race orientated exhaust like the Yasuni C16.
Can i use the mk1 With a original carburator. Just changing the jets in the carb
For best results you need a 70cc kit and very light rollers. Original carby will be ok but the performance will have a loss of potential.
@@scooterstreetau but does it not work with the original cylinder and original carb.
@@hstiller8649 As I always say, give it a go and you will find out. You will not be satisfied with the result, this exhaust is designed to function with high RPM. We tried it before and was a moment of learning.
@@scooterstreetau i tried with original carb and engine but it is really slow from 10-70 do you think a 17.5 mm carb insted of a 12mm would work
@@hstiller8649 See original reply.
Is there a big difference bitween STAGE6 PRO REPLICA MK2 and GIANNELLI REVERSE
I wouldn't say theres a big difference, the Stage 6 is probably the better of the two in terms of the greatest max power ability.
@@scooterstreetau What about sound ?
@@Kyros_PV The Giannelli will be louder for sure, and a much harsher sound from our experience. As the stage 6 is a rebadged Yasuni, it uses the same Yasuni silencer as the Z, R and C16. It has probably the best 2 stroke tone of the exhausts we've used. Nice tinny tone, with no harshness, and not too loud.
@@scooterstreetau Even if I remove the restrictors it won’t be that loud ?
@@Kyros_PV It'll be louder than the factory for sure, but the Yasuni/S6 exhausts are a very manageable volume. We remove both the header and silencer restrictor in the exhausts we sell/use.
are the performance similar or better?
Each pipe has an advantage for the correct set up. MK1 is for a high revving, higher end Cylinder, MKII will match well with street race set up. Watch at 5:20 we discuss the performance situation for each.
Isn't the stage 6 pro mk2 designed specifically for the stage 6 sport pro mk2 cilynder?
No, the r1200 is for the mkii sport pro, the pro replica mkii runs well on 50cc standart and sport as well on 68cc/70cc sport and weak midrace.
Max is nailed it on the head there, the Pro Rep MKII is essentially a re-badged Yasuni. It isn't specifically designed for any particular cylinder, but it is an excellent exhaust that will work well on many cylinders up to a low end mid-race.
@@scooterstreetau do you know why my scooter dont go faster with the mk2 on?
@@hedinolsen4363 It will depend greatly on the way (tuning and parts compatibility) you have the engine set up..
Mk2 runs great on stage6 70cc streetrace
I just bought Stage6 pro rep mk2 in my Ry6. Does mk2 have better performance?
As in the video, the MKI requires very high RPM and will deliver more power.
@@scooterstreetau What should i change to get the maxium performance?
I read your other repy😂. the MKI is no longer in production so you made the correct selection👍. Buy the compatible 70cc cylinder, and get a variator, clutch kit too.@@miskamakkonen2401
@@scooterstreetau Thanks👍
5:30 is the mk1 better than mk2. Got a mk1 on my yamaha slider.
MKI works best for a high revving cylinder. Very loud unless repacked. MKII is a little more moderate, similar to YasZ.
@@scooterstreetau so the mk1 would work better with a 70cc mk2?
@@Wil2017 MkI for higher end, it need RPM.
@@scooterstreetauHello again. I am thinking of upgrading my Stage6 Pro replica mk1 for a yasuni c16. I have got a s6 mk2 70cc sport pro on my yamaha slider. You've said that the mk1 is similar to the c16 when put to higher rpms. But on the swedish websites it says that the pro replica mk1 is a middleclass exuast and they have said to me that there is a big difference between the c16 and pro replica mk1. So i just wonder will there be a noticeble difference in my effect register and will a c16 improve the register and be a overall better exuast???? Thanks
@@Wil2017 I would agree - the C16 is step up from the MKI. Need a high revving Cyl. kit for these to work optimally.
Just as a heads up, the Stage 6 Pro Replika MKII is NOT exactly the same as a Yasuni R.. And it is quite obvious when you compare them next to each other. The Yasuni R is made of more pieces than the Stage 6. Other than that, god job explaining the differences.. The most important difference for most people is probably the power.
Yes that is right, closer to the Z but still not identical.👍Thanks for the comment and yep the power at higher rpm is where it lives.
Does the mk2 silencer fit on the mk1?
Yes but you will need the connection parts for the silencer. That is one regular comment, the MK1 is very loud.
@@scooterstreetau The connection parts from the mk1 or the mk2?
WHich one do you need the connections for?@@raksy9475
@@scooterstreetau I want to connect the mk2 silencer on the mk1 exhaust
Ok you will need the connections for the MK1, see the video.@@raksy9475
sound difference from the MK1 to the MKII?
Same sound, MK1 will be louder to start but a repack can quieten it down. also it depends on which cylinder kit you match, as the cylinder creates the noise and the exhaust amplifies it.
@@scooterstreetau currently have an airsal 50cc sport which has a bridged exhaust port with one piston ring which allows it to rev quite high, I currently have the MK1 and was wondering if there was any actual improvement other than looks?
@@oneway_sting Stay with the MK1.
@@scooterstreetau imo not same sound, Mk1 is extremely loud and sounds cheap. MK2 sounds like a yasuni R which has a much better sound and isnt as loud.
@@lostinspace2899 Just sharing what we find from our tunings. We have had the MK1 and if it pipe became too loud we just did a repack.. You are correct, the MK1 is louder first up but we do a repack.
This is our experiences with different exhaust. your experiences may be totally different.
You obviously have a MK2 and your looking into it too much, add some of your experiences.
