THE BEST MODS IVE PUT ON MY SCOOTER!

Today I threw on some really rare and very helpful performance parts on my yamaha zuma prebug. Not only did we find a polini torsen arm but we threw in some carbon vforce style reeds with a ported intake and damn did it make my scooter faster!

Great video! Heres an easy way to measure your wheel for your speedo: Use some chalk to draw a line from your tyre onto the floor. Then roll your scoot forward until the chalk is perpendicular to the floor again and draw a second line onto the floor. Now use a tape measure to measure the distance between the two chalk marks on the floor.

On a carbed zuma the best mods - front pulley take nut off, remove washer, put nut back on without, this adds 5mph top end. Blue clutch rollers and springs. 70cc head, not 100cc trust me. Variator. Leave front pully alone. Kevlar belt. Leo vince zx exhaust baffles removed and exhaust head drilled open. Larger rear spring/shock to accommodate the larger diameter rear tire with a Michelin bopper tire. This adds another 5mph top end. Dif temp ngk spark plug. Cone air filter. 21 mm carb. 68mph with 200 lb rider i take mine on the freeway no issues with MC license. Ive tried all other combos this worked best

Look into getting that arm 3d printed but with a yasuni exhaust mount.. Can 3D print metal now.

Why would you do that? It would be super expensive and complicated for no reason. He solely has to remove the mount on the exhaust side and weld in place a new bracket fitting the swing arm holes. That would look OEM and would cost less than 20 bucks.

[@AfterDark_Fi]

Love the vid! But the restriction in the yasuni pipe are there for legal reason since most of these pipes are sold in europe where some countries require them to be restricted to 50cc an top speed of 45kph

[@JyllandsBaghjul]

in denmark we have 30 and 45kph so its restricted to 30 kph if you are under 18 and after that you can get a 45kph scooter. but its still illegal to put any aftermarket exhaust on even if it tops at 45kph :)

[@bp-tuningaeroxlc-dd6474]

I agree, the Stage6 system is a bit better than Polini, but it's a shame you put a Top Performance TPR Membrane on it. It has now been proven in several places that membranes with 2 large surfaces in total atomize better in the top area, Remember that it is very difficult to notice the difference between two tuning membranes, especially when you have two types as in your video.. A little advice that I know works, make sure you use 0.30mm carbon membrane plates, also cut a defective membrane plate over so that half is as big as before, and mount it on top of your membrane plates that wiggle. you do this on both sides, about 1cm This means that your membrane plates open and close much, much faster and, not least, every time the plates close, they close 100% tightly ALL THE TIME, and the atomization is much better. I myself use this method on my Yamaha Aerox with a membrane similar to the one you use in the video.

Hey Champ, is there much loss in power using this type of engine as opposed to the water cooled units in the aerox? I prefer the air-cooled units for there simplicity and lighter wait. Stuck between going one way or the other. Also have you done much development work with the 100cc minareli engine? Really appreciate your feedback

[@ohZirox]

Coming from someone that had both engines, the Minarelli Horizontal AC one on my F12 and the Minarelli Horizontal LC on my Aerox it really depends what you want to use the engine for. If you want to tune it a bit to wheelie it easier I'd suggest going for the AC one and putting a cast iron 70cc on it. If you want to drive longer distances and like to put the throttle down for longer I'd suggest the LC one. LC engine overall handles more HP a bit better but I had a DR70 on my F12 for wheelies with a 17,5 carb and sito+ and that still ripped for quite some time. Hope that helps:)

[@independentassesor2630]

@@ohZirox It does. I really appreciate your help. Here in South Australia all of the high performance scooter specialists retired or shut down. At least these engines are easier to work on

[@ohZirox]

@@independentassesor2630 No problem at all my man, I´m Dutch and Europe still has a lot of 2 stroke scooters remaining but I see a decline in specialists and tuners as well. They put a lot of restrictions on ''heavy'' polluters and 2 stroke scooters are one of them so scooter shops pretty much only sell 4 stroke injection & electric ones nowadays. It's a shame but luckily a lot of people still try to keep them alive lol. I've also owned 3 2 stroke Piaggio Zip scooters, 2 air cooled ones and 1 original SP which is LC but in the end I've enjoyed working on the Minarelli engines the most. If you have any questions feel free to send em bro!

[@independentassesor2630]

@@ohZirox I appreciate you going into detail man. It really helps alot. Have you worked on the 100cc air cooled unit? We get them here in the Old school 2 stroke yamaha BWS . At a glance it looks the same as the air cooled 50 but just larger. Performance stock is a little dull. It gets to 100km/h with some carby , Exhaust and Transmission mods but disent look anywhere as responsive as what you have. It's quite dull. I'd love to find someone here that could help me build it. I've bought the 120cc stroker kit and a heap of Malaysia parts. I was told by a tuner that retired that it will be no were near as quick as my italjet dragster but I don't mind. I love the frame and the way it handles. It's so much lighter than the italjet

[@ohZirox]

@@independentassesor2630 The 100cc engines are the one with the drum brake in the back right? I know some people that import the 100cc's from Germany because they were more popular over there. To be honest most people only use the 100cc Aerox's for the frame so they can ride around with a motorcycle licence plate instead of a 50cc moped plate. From my experience the 100cc engines aren't nearly as good as their 50cc counterpart. A lot less parts available and even after putting a lot of aftermarket parts on it it still isn't as snappy or fast as a 50cc engine modified to 70cc. If you have the option I would 100% invest in a 50cc LC Aerox engine with a disc brake in the back. A lot more tuning potential and a lot more parts available too. If I'm correct you can also mount the engine without too much hassle, I think you only need a different subframe and loom for it to work, you might even be able to modify the 100cc loom to work with the 50cc engine but to be honest I would save the 100cc engine & loom so you can always switch back if you want. I hope this answers your questions man otherwise let me know:)
