i had the racing cylinder with the pro-replica pipe on a Gilera Runner. Runs well, but she doesnt like it at wot... At 100-115kmh when she hits about 10k rpm you feel it trying to slow down and the noise gets a Buoh sound and acts rich.
Pro-replica peaks between 9 and 10rpm, was made for the "Streetrace" cast iron cylinder.
The pipe for this cylinder is the Stage6 R1200, works phenomenally with it ! Or R1400 if you want to chase rpm and get a rotor ignition.
Have about 2500km on it, lots of torque withe the r1200, no hesitation, so far no loss in compression, ring still great, no carbon build-up, no scratches. Runs like a beast for a little 2stroke engine.
So good to hear your set up. Really appreciate this information and the performance you have with the R1200. What oil do you use?
@@scooterstreetau i only use 1 oil for premix - Motul 710 at 2% mix. Never ceased a piston, ever!
My setup is:
S6 MK2 Racing cylinder
S6 mech water pump to get rid of the oil pump.
S6 Vforce reeds with 4mm petals.
(standard size, no case milling)
S6 short manifold with spacer
Polini PWK 28mm carb (without powerjet)
MVT Digital Direct rotor ignition.
S6 complete Overrange CVT kit
(4.5g rollers, medium torque spring, red stiff clutch springs)
Malossi RHQ mhr crankshaft.
Stock gears.
top speed 135km/h, 19hp.
I also noticed she only likes the plug BR10 -EG.. misfires with any other plug 🤷♂️
@@joaomelo61 So cool. This is an amazing set up. What is your air system? Tyres?
@@scooterstreetau tires i use ContiTwistRace.. not bad at all for the price, only slides when i want it to slide.
Not sure what you mean by air system.. its a liquid cooled Gilera Runner.
air intake is all matched to 28mm from the venturi to the reeds (with stuffer in reed block).
High flow malossi filter, that big red foamy one.
Dont like it that much, its too loud but its what the donkey wants 🤷♂️
Pilot jet 45 - main jet 120 in winter and 118 in summer. ✌️
@@joaomelo61 Air system = Malossi high flow filter👌 nice. Agree, very loud back noise. So impressive with the jets for the different seasons, well dome mate🏆
I appreciate making this comparison video
Thank you🙌
I really love your videos, thanks alot for sharing.
Best regards from Denmark.
Ahh thank you so much. I have been to Denmark and work in Stenlose.. Beautiful People...
Hvordan går det? Skil got😂
@@scooterstreetau hahaha, Denmark is lovely place,
Ja det går skide godt 😂😂😂
@@scooterstreetau btw, i have the mk2 sport on my gilera stalker, and i could not be happier with it, it is fast and nice responding 😀😀
@@Fupaa-. 🤣🤣
@@Fupaa-. I didn't know the full translated meaning😮😂. and yes excellent performance.....
Enjoying your channel 👍
Glad to hear, thanks for the support🎉🎅
Love my mk11 race kit I brought from you guys goes hard with the stage 6 replica pipe
It would be a Savage set up😎
I am running a replica pipe on a stock bore
@@holldendix9658 I bet it’s loud and slow
@@captainsavage5043 if u tuned it like i did my piaggio zip does 82 kmh an hour and acceleration is not bad either
Great video! I can’t wait my Sport to arrive !
Superb quality parts and they work!!!😎
@@scooterstreetau What else would you recommend for the sport build? I got the Malossi 2000 multivar, Yasuni R, and green springs on Polini clutch already installed. Planning to get Polini cp 21, air filter, ...What else? I have the 2004 Derbi Bullet et2 piaggio engine.
@@sunnybeachweddings7037 wow, very nice set up, upgrade the variator to a higher class to suit. Apart from that you have yourself an already better than good line up for street.
www.scootertuning.ca/en/variators-sport/31009-variator-malossi-multivar-2000.html This is the variator I have, it’s one of the top in the sport category. Are you referring to put a mid race oversized variator? This will be a daily, weekender Scooter...not a race. I have a list with about $400 parts more to add... and I’m not sure exactly if I need them all… Let me know please what do you think... Polini cp 21 manual choke, thermometer gauge, reed valve,intake manifold, stage 6 harder clutch springs, new variator pulley, and the few gaskets...
@@sunnybeachweddings7037 We can really only give specific advice on parts that we know and sell. The Malossi Multivar is a great unit. It depends what you're trying to achieve, we usually recommend installing one part at a time, and not mixing the brands up too much. Your parts package needs to match, this can be done with mixed brand parts but it is often much easier sticking with one brand.
The MKIISP wants to rev up to 12000rpm with an R1200 exhaust etc., the MKIIR goes up to 14000rpm with an R1400 exhaust so the MKIISP is a true midrace cylinder und the MKIIR is a true racing cylinder.
I would agree. The MKII Racing is certainly a race level cylinder, however compared to the equivalent product in Malossi and Polini it is at least 15% down in power. Thanks for your comments👍
@@scooterstreetau which one would be faster mhr replica or stage 6 racing with similar setup?
@@MondiSTT Depends highly on what you mean by faster... The MHR Rep will have more off low and mid range torque which is very practical on the road. The Stage 6 Racing is a race cylinder, and the rest of the setup of the bike needs to match for it to work properly and get power to the road - if it is paired with a good race exhaust, transmission, inner rotor and large carb it is capable of a fair bit more power. If those conditions are not met, it will be an absolute pig to tune and ride.
On the race version, if you widen and raise the exhaust duration very little you could get 20+ something hp, on 8:1 final drive gearing it is very possible to achieve over 90+ MPH on a normal stroke crank and rod, and lightened oem fly wheel. Of course transmission components for the obvious reasons.
This is great info🔥🔥
🍻😄🧙🏽♂️. I had used the S6 R1400 exhaust, the Yasuni C30 was the original plan to test but wasn’t available at the time of build, this was 10 plus years ago.
Stage 6 race cillinder has a butterfly exhaust gate but in Netherlands we use mhr speed 7T 💪💪much better OR 86.4cc Malossi bigbore cillinderkit
2fast cillinderkit 90cc
Polini big EVO 94cc
Yes, so many options..
What do u think of the naraku ķit full bottom and top end What exhaust would u recommend thanks
We have not had enough experience with the Naraku Cranks, I can say that we are confident with the quality of their Cylinders.
I am looking for a 50cc cylinder to go in my Yamaha aerox and want a good kit with good power but still reliable for day to day riding just wondering what a good kit to get would be and if cast iron or aluminium is the way to go
Malossi MHR Rep, Stage 6 street Race. Aluminium is a good option, The Aerox is water cooled so this is an advantage for cast or Ally.
Greetings. good video. Could you help me. it is a gilera runner50cc i have a tecnigas triops a naraku crankshaft and a naraku 70cc cylinder. I want to change the cylinder and I was thinking of a stage 6 RT. or which one would be good for what I have. thank you
Hello and Thank you.. With the Stage 6 R/T cylinder kit you are encouraged to follow through with high end exhaust, transmission and ignition. If you are prepared to go there we are right behind you🤘
You should consider a street race kit as you have a great exhaust to suit the class system without going over the capabilities of the exhaust. Stage 6, Malossi, Polini and Top Performances all make Suitable cylinder kits, with Polini and Malossi run with twin rings pistons in this class.
Hi, planning to install the sport MK2 cylinder on my ovetto, i currently have a yasuni z exhaust. I would like to know wich stage 6 exhaust, between the pro rep mk2 and the r1200 would you recommand me in addition of the sport mk2 cylinder please ? (I want a full stage6 config)
Either pipe will be fine, the R1200 is for the higher revving and would compliment if you had the extra upgrades, carby, transmission and even inner rotor ignition. The MK2 will provide a torquey street machine that you would find easier to tune and have good reliability. If you contact Stage6 they can advise the entire set up from Cylinder, intake through to the Crankshaft..
@@scooterstreetau awesome, thank you for your response, very informative
I run the Mk2 sport with the S6 pro rep exhaust. Hitting high 60s on my Derbi Atlantis.Would a Malossi k15 CDI and C16 get me to 70+ ?
Assuming thats in MPH😂 Short answer is, possibly. The MK2 sport has a fairly standard port map, but the port timing on that kit is set up for high RPM. With the Pro Replica exhaust, it is possible that you're hitting the rev limit. Unfortunately only way to know for sure is to fit it and see.
Troy, what are the rest of your performance upgrades? I am about to start upgrading my 2004 Derbi Atlantis Bullet. I also got the Stage 6 MK II Sport and a few other parts ...
wich cylinder would u recommed me the S6 Sport Pro or the MHR Replica? Im drive on Road daily in year ca. 7000km. Wich cylinder have more power. I have Yasuni R or a Gianelli Shot as exhausts.
The Stage6 Sport Pro is a good value fun street kit, it has a single ring so may not last as long as the Malossi but if your looking for good power to match the R and Shot this wont disappoint.
Looking to install a s6 sport mk2 on my 2003 Zuma with a yasuni R. Can this work on the stock 10mm crank ? I've only run the Athena sport kits in the past.
Yes it will work!👍 Make sure all of the parts are in excellent condition and not worn...
@@scooterstreetau gotcha ! Thanks gor the reply looking to the performance with this cylinder.
@@nickritter1992 Keep us updated..
How does the stage 6 cylinder compare to mhr replica in regards of power
The Sport cylinder is similar in power to the MHR rep, though in our experience the MHR rep makes power in a lower RPM which is often a little more usable on the road. The Stage 6 Racing cylinder makes a fair bit more power than the MHR Rep, but at a much higher RPM.
What crankshaft do you recommend using paired with stage6 sport pro mk2
We usually recommend the Malossi RHQ as a great general option, the Stage 6 cranks are also great.
doppler endurance is the cheapest and it does its job
I have a 2006 Derbi Bullet. I have a Malossi Multivar 2000 and Yasuni Z pipe. I know im doing this build backwards but i want a 70cc big bore but unsure what would suit my components i have. Malossi sport or Stage 6 sport pro ( both $250 cad) or Malossi MHR ($440 cad)? Thanks
Stage 6 SP.👍
Any one know of a pro rep mk2 pipe fits on the mk2 racing cilinder?
Sure does, we would however recommend a more racing orientated exhaust with the MK2 Racing cylinder. S6 MKII exhaust sits between the performance level of a Yasuni Z and Yasuni R (being that the S6 MKII exhaust is manufactured by Yasuni). A Yasuni C16 or similar would be far more appropriate, the S6 MKII will be restrictive to the cylinder.
For a cpi oliver , can i run the stock oil pump? I heard some people saying it cant he used , i need some help
You need to make your own choice. For me I always run the stock oil pump. On these Chinese models you can adjust the oil pump cable at the pump to activate earlier. If the system is working fine I keep standard system and recommend maintaining it on a regular schedule.. good luck👍
@@scooterstreetau awsome thank you so much
@@alessiourban181 Thanks for supporting our channel.
Actually the mk2 sport pro works the best with c16 stage 6r1200 or a similar exhaust the racing best with r1400 yasuni c20/c21 voca road race and similar exhausts. The mk2 exhaust is a low revving exhaust made for cast iron. It will hold alu cilinderkits back!
Yes we prefer the Yasuni R for the alu.
I have a yasuni c16 and a stage 6 sport pro mk2; should a stage 6 racing mk2 give me alot more power?
@@biddo7456 Yes.
@@scooterstreetau then ill order it, thankyou
@@biddo7456 Yes.
I’ve got a mk1 racing with a c30 it flys
Thanks for sharing🙌
Any idea what the squish should be set to on the sport?
From memory, approximately 0.7mm squish - but I would definitely refer to the instructions, as this is fairly crucial.
Between 0.75mm and 0.85mm refering to the description of the cylinder on maxiscoot
what the best exhaust for STG6 Racing 70 ? Yasuni Carrera 16 or Carrera 21 ? thanks
Racing MKII= C16. Street Racing = C16. Top Line “Big Bore” =C21. stage6-racing.com/products/cylinders/?lang=en#!/5
Put voca road race on it cheaper and around 14000 revs like r1400
I'm sorry I'm kind of a noob to all this, but shouldn't there be two ports, one for carburetor and one for exhaust, am i missing something?
There are 2 ports... watch an animated video on the 2 stroke engine, very interesting and will explain the method.
What is the difference between 2 and 1 ring piston?
Twin ring pistons typically have a longer life span between rebuilds. Single ring pistons often provide more power, but have a shorter life between rebuilds.
how often will i need to change piston rings on a racing mk2 cylinder with a c16 exhaust?
Check at 5000kms and clean the ring if carbon is present. 10'000kms would be the time to change but that is not the final word as there are many factors that can effect the life of the ring/piston. When first fitting the cylinder do a compression test and take note. After 1 week do a compression test and take note. Now you have the new kit PSI value so at any time you can do a compression test and compare to the initial comp value to see if the compression has changed, lost pressure. Being consistent with fuel type and oil type and using a better standard spark plug can help the longevity of the cylinder, piston and ring.
@@scooterstreetau 5k? i was thinking 1k kms was a stretch.
@@rockys777 If racing, Yes 1k or less.
@@scooterstreetau not racing, just street use with a c16 and a gear up.
@@rockys777 ok cool 👌
I had the racing MK1 on my Aerox. It likes to rev!
The MOT tester said "it's a noisy bugger!" 😂
That would have been a BEAST!
@@scooterstreetau it was. You had to be in the right mood to ride it.
@@paulbudford And be wearing the right gear, what a hoot..
Same i got it for the GIlera Runner.. that thing is an RPM chaser!! Lots of Power
@@joaomelo61 niiiice.
Dónde lo venden?
Los vendemos y también la empresa stage6.
can the sport run with standard crank?
not recomended!
Yes you can, but an old system will suffer sooner and then all will need to be replaced. An upgraded Crankshaft is the best way to go.
@@skrivelis4315 You got our back🍻
The sport is from cast iron and the race is from aluminium or one is racing and one replica
Or is it like malossi MHR AND MHR REPLICA?
@@iulianbarzu3384 in the Stage 6, theyre both aluminium cylinders with Nikasil bores, and single ring piston. The only difference is the port map. The Malossi Cylinders are a little different.
@@scooterstreetau oh thank you. You should do racing vs racing replica from malossi
@@iulianbarzu3384 the replica is not a racing cilinder its a mid race with around 11.500 rpm's max the mhr takes around 14000 like the stage 6 racing so no man
