    Great article! When you say homologated, are the results with the restrictor washer removed or kept in place?

    Hello Daniel, a really interesting aritcle. So good i read every single word of it BUT you seem to have mixed up something:
    The graph, the RPM with the most power and even the torque is identical between the Hebo New Performer and your price-performance winner the Stage 6 Pro Replica.
    I was wondering if the mufflers are that similiar but after reading the text below the Stage 6 Pro Replica i am pretty sure you accidentally copied everything from the Hebo New Performer and pasted it in the performance graph and even the text of the Stage 6 Pro Replica.
    Below the Stage 6 Pro Replica graph and text it clearly says “streetbuzz nitro hebo racing” just like in the description of the Hebo muffler.
    Sorry for my bad english but i had just some years of english lessons at school.
    After a new overview, what is the S6 Pro Rep really about ???

      Yes, unfortunately Streetbuzz fucked it up and posted the wrong datasheet. They later had a screen of the correct one but it was only possible to read the horsepower and not the torque. The Pro Replica is indeed really good! I would recommend it any day also because of the high quality and fitting Stage6 provides!

        Ok, so still your price-performance winner….?
        Can you please tell me how much horsepower the Pro Rep generates and at wich RPM it generates its maximum horsepower ?

          Oh, nevermind !
          I think i found the answer in the charts, 10.5 hp at 8608rpm – right?

            Yes, exactly! Stage6 also has a really good quality so you will be really happy with it. You should have a look at ebay. You can buy it really cheap there sometimes!

    Hello Daniel,

    Would the Yasuni city 16 perform a bit better than the Yasuni R and a bit less than the Yauni c16?

    Hi Daniel

    I have a modified Kymco Like 50 with a Malossi 70cc cylinder and variator kit. I am looking at the following three pipes: Leovince ZX-R, Tecnigas RS II, or Tecnigas Next R. Which pipe do you recommend with the Like 70cc for improved lower end and higher end performance?

    Thanks
    Ross

    Hi Daniel, do you have any thoughts on the Naraku Traffic exhaust? Which exhaust would you recommend most with the Kymco Like 50 2T with Malossi 70cc kit? Thanks! Ross

    Greetings Daniel,
    I bought the tecnigas next R and I’m disappointed, because the results was quite the opposite from what I expected it didn’t gave any power instead lost power from take-off and top end and the engine sounds slow. any ideas what should I do?
    my current set is:

    1)Taiwan 120cc cylinder kit
    2)Malossi double sponge on original air box
    3)Malossi reed block with that thing (I don’t know what is called… lol) that makes the hole from square to circle installed
    4)Standard carburetor with main jet 80 (standard jet 74)
    5)Malossi multivar variator kit with 9.3gr rollers and white contra spring
    6)Malossi belt
    7)Naraku clutch

    Thanks Petros

    Great article, very interesting. I’m stuck; I have a stock Piaggio Typhoon 80 and am looking for a decent exhaust that fits. Stacks of options for the 50 and 125 but nothing listed for the 80. I’ve read that a decent 70cc compatible exhaust would be ok but not sure if the connection to the cylinder port is the same. Any info appreciated! Current thinking is the Yasuni Z may be way to go. Cheers!

    Hi Daniel,

    Many thanks for your recommendations, I’ve had the bike 15 years and restored it like new and the exhaust will be the icing on the cake so to speak. I reckon there’s a lot of untapped potential in the engine (new cylinder etc this year) and the Yasnsui C16 does sound the part — there’s a city version too which means I can keep the centre stand so will go for that. Will report back with the results in due course!

    Cheers and great article once again. Neil

    I have a 08′ Zuma 50 with a Top Performance Black 70cc BBK. I have the stock 10mm crank and I’m looking for a pipe that doesn’t rev super high as I don’t want to destroy my stock crank. Also… I had a Leo Vince ZX-R and it was damaged. I’m looking to replace it with something else. I want max performance but don’t want to blow the 10mm crank.

    Thanks!!!

    I like the Stage 6 Pro Rep, but people say it revs to high for my crank. What do you think? What would be your first choice for my setup?

    hello Daniel
    I have a 05 zuma with malossi sport 70 kit. have a 17.5 dellorto carb stock air box and a brand new pro replica pipe. I cant get this thing to rev up with any power so I changed the pipe to my leo zx and it just rips. I then took the pro replica and put it on my stock 50 and it does the same thing no power. any idea what might be the problem with the pipe? I did remove the header funnel in it
    any help would be great

    hello Daniel
    first you rock with helping people out!!
    ok I have my 70 set up tuned perfect to my leo zx. it is rusted and welded a few times thus replacing with the pro rep. on the stand it will rev up but just doesn’t sound crisp. I can jet and needle adjust real crazy and doesn’t seem to change much. with the leo on I have 5 gram sliders in koso clutch and it screams up to 45 and gets there quickly. I put 4 gram rollers and still nothing with the pro rep pipe. is there something inside that might have been bad from new?

    I have a stage6 race mk1 70cc kit with an athena upgraded crank, 21mm dellorto 90/45/w7, stage6 torque control with red clutch spring at max tension. the scooter launches at 8000 and it rips hard.

    anything below 8000 it’s a snail. my leo vince zx-r has tons of power from idle to 8000, but nothing after 8000.

    i can’t commute with the city16 since it can’t go slow :( any help?

    Hi!
    Is there is also a muffler restrictor in a Turbo Kit pipe set? Or is it just a noise-killer..
    The restrictor at the manifold is removed and I noticed a small pipe going in to the perforated chamber in the muffler when i re-stuffed it.
    Thanks

    Daniel, not sure if this is still active, but BIG kudos for doing this work. This kind of information is really valuable, and I know It took alot of time. I have a dynomometer myself and I am aware of the labor! Anyways I picked up a 00 aprilia sr50 with top perf pipe, bore, and dell 19mm/stage6 vari kit. I can’t get it to run with any less than 3/4 throttle input. Once I get the revs up its fine, but when going from idle up, it cuts out completely. Im running 90mj, 45pilot, 60 choke. I have heard the needle position is huge on these, does that sound like my issue? Its an absolute rocket once I can nurse it past the dead zone.
