Tyre Slaying Piaggio - Brad's MHR Racing 70cc Zip Build Breakdown

[@Clicklord]

first video i have seen from you guys and subbed straight away, inspiring for me to see aussie mechanics on yt!

[@scooterstreetau]

Sweeeet! Thanks so much for the support🙌

[@victorhawkins3461]

Fine build, Brad! I'm the guy you folks sent the logo to for T-shirts. I'm hopeful I can do (or have help doing) a similar build on my '01 ET2 50cc. I really, really dig your videos! Cheers!

[@scooterstreetau]

Good stuff Victor, very simliar engines on the Zip and ET2.

[@paulbudford]

Brad you hooligan. 😂 Nice build. The zip sp is on my dream garage list. Even though I'm a Minarelli fan.

[@scooterstreetau]

Yeahhhhhhh😆 Oh the Zip SP, what a weapon!

[@foreignautomobiles]

Awesome. Always enjoy watching your content!

[@scooterstreetau]

Thank you Brother🙌

[@foreignautomobiles]

@@scooterstreetau you are welcome, I decided to mod a derbi gp1 because of all the praise you give the hiper2 motor. Way more beef than the minarelli in my Aprilia rally

[@scooterstreetau]

@@foreignautomobiles Oh really, that's great. The Derbi GP1 has huge power potential due to the liquid cool system.

[@foreignautomobiles]

@@scooterstreetau yeah, I'm in the US so we are a little limited in what we got over here. I found the GP1 and had to have it. I've got a rep kit, yasuni c10, 21 or 25mm dellorto, multivar, malossi torque driver, it's a ripper.

[@AndrewQuadling]

Hi piaggio zip ac owner from UK looking forward to seeing all mods you do on your zip👍

[@scooterstreetau]

Hello to the UK, thanks for watching Lad👍

[@millymoo6575]

Very cool! If I wasn’t 10,000 miles away I’d pop down and have a look 😂

[@scooterstreetau]

CHeers, and have a ride, the video does not give it justice, pulls the front wheel so easily.

[@mariohihi6618]

hey, loving the videos i learned a lot from them. Can the next video be on hot to delete/remove oil pump so i can put premix in? Cheers

[@scooterstreetau]

Thanks for the feedback and support, we love it and it helps us produce more videos. Great suggestion for a video👍 Until we make that video all you need to do is remove the belt for the oil pump and start at 30:1.

[@Angerfisters]

I think we need to see Jog R soon. Are you ever messing around with RC-one engines?

[@scooterstreetau]

I will pull it out this year. We plated with RC in early years but not anymore. Very time consuming. Watch the RC-One videos Malossi.

[@afz.70cc]

hey brad! love the build , can i ask you what is the consuption on the setup?

[@scooterstreetau]

There is no measurement for unlimited fun🤘She's thirsty due to WOT.

[@Utopiaottoway]

i am going to buy my first zip 50cc 2T. I really want to upgrade but is your shop in Adelaide?

[@scooterstreetau]

So excting! We are Gold Coast 🏖

[@emilycorner3444]

Dellorto PHBG 21-How is it possible that it has settings on this side ??

[@scooterstreetau]

This particular carb is made for the Piaggio engine so the adjustments are over the exhaust side, easier to access the mix and idle. Thanks again

[@balamood6183]

Does the polini riser fit well with the long mudguard? Have heard that it does not fit well with it.

[@scooterstreetau]

I am not sure, have never tried.

[@balamood6183]

@@scooterstreetau Ty for the answer! How do i bolt on the exhaust on the zips? Cant get to the bolt well and its kinda loose, the exhaust.

[@scooterstreetau]

@@balamood6183 Watch the Zip playlist, we have a video on how we fit it.

[@spieha]

What jets you have in this carb? Ive got polini sport 70cc with dell phva 17.5 80 main 38 idle jets, s6 pro replica, polini hispeed and malossi delta clutch. The only issue im having right now is thst when i relese and go again full throttle again it sounds like its got no fuel, and it takes a second before it gets back to gaining speed. I have brand new 21mm dell phbg but it has 60 idle jet and the cylinder gets flooded with fuel, had to take exhaust off cause it was full of fuel after kicking it for too long

[@scooterstreetau]

Watch our latest video on Carby tuning. 60 is a large size for idle.

[@danalexanghel]

Hi Brad! Great episode and nice build. I myself have a Gilera Runner SP50 LC 2006 spec with a 47mm bore kit(china one) , standard 17.5 Dellorto carb+airbox , Malossi Wild Lion exhaust and onboard oil mixer . I have 3 questions: 1. These chinese big bore kits - what lifetime should be expected from them? 2. What power gain is expected from a big bore kit with derestriction and Wild lion exhaust? Is it close to a chinese Gy6 125cc engine AC ? 3. What should be the best jet setup for my case( I run with 34 pilot and 68 main)? The only measurements I can make is the noticeable difference on take off and max speed.I can see that from stock 49cc vs 68cc acceleration is much more aggressive and I manage to reach 95kph on the clock when I run out of road. I run standard transmission with 6.5 gram rollers. Great work!

[@scooterstreetau]

Chinese kits can vary, they can make brilliant products and also capable of low quality products made for a budget. Minimum should be 6k. 30%+ increases. GY6 is 4stroke. Whith a LC engine load up as it will accept the higher class performance parts. Thanks for comments and views👌

[@Jaxon_chickenjoe9]

Would it be possible to get the same results with the same modifications from a Vespa s 50 2T as you would from Piaggio zip?

[@scooterstreetau]

Yes absolutely👌

[@waltren1513]

Hi. Recently put on a new performance variation and now there is a strange noise? I’m not sure if I’m paranoid and the sound has always been there because I did open it up and everything looked normal. I’m thinking of putting the original back in to see if the sound disappears. The scooter is an sr50

[@scooterstreetau]

Sometimes a new belt can give a whining noise, yes try switch back.

[@Al-AmirWajihAyoubi]

How do I get in contact with you’s for parts

[@scooterstreetau]

See description, www.scooterstreet.com.au

[@numankralj]

Hi! I have noticed with my 2016 zip 2stroke (everything stock) that when i have my gas 3/4 it runs well but when i give it full gas it feels like a restriction? I have just changed the air filter

[@scooterstreetau]

Did it do this prior to change of the air filter? When we see this it usually means too much air over balancing the fuel mix. Lean. If it splutters then too restricted on the air filter. Rich.

[@numankralj]

@@scooterstreetau i think that this was also with stock air filter

[@skullxyt7878]

what do you think of the pegasus sky50 or the tgb 101s?

[@scooterstreetau]

We have TGB in Australia and they 101s is a fun scooter and the large off road tyres allow beach and dirt exploring. Limited performance parts make it a less option for big tuning potential. Get a gear up mit in there and lighter roller and a Polini adjustable clutch straight away.

[@neubit26]

Hey Brad how are you doing just need help on my Piaggio typhoon 50 4T 2021 north american model i change muffler yasuni R but for some reason it bogs down and very hesitant on going somewhere mid trottle i did up jet it 3 step 72 original to 80 still same i even tried 92 still same i did try change ecu to malossi injectronic still same . Im not sure what im missing here. A guidance will be a greatly appreciated thanks

[@scooterstreetau]

Have you tuned the carby, variator and clutch?

[@neubit26]

Not yet but worried that i cant fix the bogging down issue and having all the parts i cant use

[@scooterstreetau]

@@neubit26 Have you watched many of our videos, we discuss this issue as a regular topic.

[@balamood6183]

Hello, do you guys think i should use a pod filter with airsal t6 70cc or the air box with it? Everything else is original other than the exhaust, i am also gonna keep the original carburetor.

[@scooterstreetau]

It depends if you want noise and heavier fuel usage over less noise and better fuel economy.

[@balamood6183]

@@scooterstreetau really not important, just performace that i care about.

[@scooterstreetau]

@@balamood6183 If that is the direction, go for transmission upgrades, over range, Upgrade the carby with POD and fit inner rotor ignition.

[@balamood6183]

@@scooterstreetau broo, i meant is it better to use pod or air box, i dont want to spend that money. I meant is it better performace wise to use air box or pod filter.

[@scooterstreetau]

@@balamood6183 Everyone will have a different answer, I rather the Airbox. Did you watch the video on POD Vs Airbox?

[@Funycat1]

My forks hew a play on my gilera stalker how can i fix this ?🙂

[@JDMz]

You'll need new bearings. Fork seals aswell.
