Hi, I've got two Malaguti F15's. 2003, One 50cc the other 70cc. Both liquid cooled. I bought them with zero mileage recently. I've fitted polini variator, polini clutch springs and a wider, slightly longer belt. It now does 55mph even with a passenger. Only way to get higher top speed is to change the gearing to the rear wheel..which i won't be doing. The 70cc is next on the list to get running. Strangely the 70cc has the same dellorto 12 carburetor as the 50cc. Your video is great at highlighting the benefits of a bigger carburetor...even for the 50cc. Keep the great videos coming.. Cheers from the UK.
@overlandworld2253 thanks for watching and for the kind words. I did a build video of my malaguti f12 that led to great results. Top end on the setup of the malaguti in the video was a s6 racing cylinder polini 4 race exhaust. Stock gearing is quite tall on the malaguti so I was able to hit 74 mph, and others in the u.s have hit 80 mph with even more spicy cylinders and exhaust setups. But your mods will definitely work very well :) along with a polini cp 19 or 21 carb can also be a great upgrade for your 70cc malaguti.
@GotThrottles from initial launch to when it shifts around 50 it will go from 13200 to 12900 (less power at that rpm) it's happiest in the 13.2 to 13.5 range, highest I've seen was hitting over 70 with room to with 13,600 and climbing. Thanks for watching I'll be doing an update on another project I'll hope you'll all enjoy and continue fine tuning the zuma
@@X7rocks Looking forward to it. I have basically the same bike, Bugeye 70cc kit, Yasuni pipe, TOP variator and other components to make it work. I'm concerned the stock Yamaha crankshaft can't take those higher RPM's for long so I've added weights to limit it to 10,000 rpm during acceleration but I admit it feels like it makes more power in the 11-13k rpm range. So i either pray the crank holds, or give up and buy an aftermarket crank when it does. I will make a Dragy video with mine. How is your crank holding up?
@GotThrottles so far so good! Though there is much more power possible with the crank being swapped. I have one fun project for a drag engine being handled at the moment and will try to upload that and pick up a crank for the current engine as it should lead to good results with more air and fuel being directly funneled into the cylinder. This is the 2nd zuma engine I've had to handle over 10k rpm. Though it can last (had it last 7k miles before) and was really for it to handle the power. I do still recommend it for more higher end setups. For sports setups you're definitely good to go for a while.
It can touch the bottom of the seat container, but that's the most of an issue I've had. Just need to Make sure the throttle cable as a short 90 degree fitting for the carb will fit nicely.
@tjjohnston7920 while the benefit of more case pressure being forced into the cylinder would he worthwhile. This is to see how an engine with over 7k miles can handle the cylinder and exhaust combo. A full circle crank is next along with porting the engine carter's. Which show a good result on the malaguti.

@@X7rocks thanks for the advice 🙏
Love the zuma vids! Always gotta like and comment
Thanks bud! Always glad to get more :) and future plans are going in motion aiming for 10 second 1/8 mile. And I know I can get ut.
Nice build sir
@lizettefiguerres-dm1sn thanks for watching and thanks for the kind comment, more update is upcoming so, the goal is 10 seconds in the 1/8 mile :))
@@X7rocksare you in us sir?
@@lizettefiguerres-dm1sn yessir out in florida.
@@X7rocks i got mine to in my short vid sir

Me puedes ayudar con el vídeo completo de como instalaste las mangueras del carburador 🙏🏿

What is the size of cylinder wrist pin? 10mm or 12mm
@@MANOWAR1917 it is a 10mm wrist pim
Great build! What kind of RPM are you seeing during shift and what’s your peak recorded RPM? Stock crank holding up?

Hey, sick build. I am looking to do an upgraded carb on mine. did you run into any issues with space with the storage box? Thanks
It can touch the bottom of the seat container, but that's the most of an issue I've had. Just need to Make sure the throttle cable as a short 90 degree fitting for the carb will fit nicely.
With everything you did, I would've put In a full circle crank.

...I am totally not looking for an older zuma now. Nope. Not this guy.
No possible way at all you'd be looking for one 😜
@@X7rocks Definitely not nope. Sure as hell not bringing it up to my girlfriend either 🤣
