Best Piaggio Zip Street Setup? MHR 70cc & Yasuni R Tuning Guide

[@Ice-T.]

That combination of cylinder and exhaust is great I had Yasuni R on my Runner 50 with stock cylinder, great exhaust

these motors love small jets coming from dios running twice the carbs and mains its fun to see bikes go so quick on 70 jets my typhoon main jet is like 68 and im doing 95! or 60 mph to us Americans

hello, nice video i have a aprillia sr 2006 it runs on pwk 21 streetrace 70cc, i had a yasuni r and i thought giannelli shot v4 will have a better powerband, but when i put in the shot, now it runs way worse no matter what tuning in transmission or fuel i do. Its really boggy/sluggish, when it reaches like 70kmph it bogs down almost , but the weird thing is that this happens when its hot, when its cold it runs mint, i tried putting bigger jet, which also didint help, do u have any ideas ? thank youu

[@scooterstreetau]

This exhaust needs higher rpm.

[@GaspersStuff]

Did you drill holes in the original air box? How many turns on the air screw? I have a Piaggio Zip with airsal 70cc aluminum single segment, Yasuni R and Dellorto 17.5 with original air box and two 10mm holes and I'm having a lot of difficulty tuning it. The best I can do at the moment is with 4 turns of the air screw!!! main jet 88 small jet 34.

[@scooterstreetau]

Yes. 1 turn. 😲4 turns means it is very rich. Check the choke and eleimanate any carby/ engine issue prior to tuning. Go back to standard airbox and tune the carb to suit, once you are happy with this then start to open up.

[@GaspersStuff]

@@scooterstreetau Thank you very much for your help, not all KZbinrs help us in this way and this must be appreciated! In your case, in which area of ​​the filter box did you drill the holes? And how many? Wish size? (mm)

[@scooterstreetau]

Your welcome ​@GaspersStuff 🤙 We use Pop Stuffers tinyurl.com/popstuffers as the holes for the air box, drill a 14mm hole and insert. The holes are made anywhere suitable in the entry side of the air filter so the intake of air flows through the air filter element.

[@sebbyseb2009]

Hello! I have a Piaggio zip SSL1T 1991-1994 and somebody has change the clutch inte the back and it's missing bearing, roller cage and other springs according to a blueprint I found online. I have changed almost anything except for the back clutch cause the moped was very slow to 30 km/h but fast to 50 km/h when it was original. The problem remained even after i changed anything except for the back clutch. I would like to hear with you how this assembling of the back clutch its really gonna look like. Unfortunately some parts are not avaliable from the blueprint charts. Thats why I want to ask you guys to if you know how its going to look or if you know some company that sell these spare parts, second hand or new.

Hello, i have a 70cc malossi iron kit, 21mm dellorto, mhr variator... but what exhaust shoud i choose? I was thinking yasuni c16 or maybe something else.

[@scooterstreetau]

Very nice question! Carby👍Variator👍, upgrade the cylinder if you fit the C16 as cast iron cylinder will not produce the rpm required. You will loose the take off due to the physics of the exhaust so go for an exhaust like the Yasuni R. The slower the taper of the header the better the take off, sharper the chamber requires higher rpm to get on the pipe.

No, it is higher at the top taking a longer gear. Larger diameter. This is where you can use shims in the variator.

Well 19mm is fine, totally up to you in the selection. Start with airbox, remove snorkel and add 1 or pop holes. Go to pod if you really want to.
