Vittorazi Atom80 Complete 2 stroke Engine Overhaul (Teardown and rebuild)

[@martinburgui7241]

thank you very mucho for watching

Thank you for all the work that went into this video. It's a superb resource and I'm sure will help many people - myself included! Thanks again. 🙂

You’re welcome Dan. I like working on engines, so I think filming and editing this was tougher for me than the actual engine teardown and rebuild. I’m happy to see and hear that others are benefiting from it too. That makes the work worth it in the end. Thanks for the kind words.

This was a great video, thank you so much for making it. I watched it at least three times while doing my 200 hour maintenance which according to the manual requires all of these steps. That said, my engine looked great and much of the work was possibly unnecessary. I especially appreciated your approach to freezing the crankshaft and heating the crankcase beyond what the Vittorazi manual suggested as that worked great. The solder trick for the clearance measurement was fantastic as well. Again many thanks for the "virtual hand-holding" while I did this work.

Thanks so much David for the nice comments. It took a lot of time to make this video so I’m glad to hear that you found it useful. Hope to see you in the air!!

In training they said, 'if you're not a two stroke mechanic now, you will be if you stay in the sport'. Thank you for taking the time to make this video. Not having much experience working on engines, especially PPG, this is a phenomenal resource.

[@wednesdaykartingflyingclub8164]

Thank you John. It’s always easier watching somebody else do something before venturing into the “unknown”. At least you’ll know what you’re getting yourself into. In fact, this video might show some people that it’d be better to seek out somebody that has the experience already rather that tackle it on their own. I came to this sport having a decent level of engine knowledge (by no means an expert) and have always preferred (when possible) to fix things myself that way I have a better understanding of what needs to be done next time. Anyway, thanks for kind words. This video did take a long time to make. I’m just glad that somebody else found it of some value too.

Thank you for this great video, it's extremely useful. Also, extra thumbs up for keeping it to the point and without annoying music.

This is the best video for ATOM 80 owners. It is my favourite ! Thank you so much for your excelent work and images. Now I want more! Would you please show us the electric system and replacement?

[@wednesdaykartingflyingclub8164]

Thanks for the kind words Martin. This video does show removal and installation of the coil and flywheel. Other than that it’s really just the kill switch on the throttle. But the throttle would be different for every frame manufacture. But let me know exactly what you’re looking for and maybe I can make a video.

I really appreciate the step by step video. I have yet to try and get a manual for this motor, but would be interested to hear which pullers you used in your rebuild.

[@wednesdaykartingflyingclub8164]

Here’s a link to Vittorazi’s maintenance manual. I made this video about a year before the manual was published. So keep that in mind. I did buy all my parts along with a flywheel and multi (prop hub/ clutch) puller from www.skysportsusa.net. The other pullers/case splitters I made using flat stock aluminum and correctly sized bolts. vittorazi.com/manuali/Maintenance_manual_Atom80_Eng_022.pdf?fbclid=IwAR3Q-giff3-l5xb9oVDGjdLas3HvJzciFITj2-omuz2YC-93aW-U9LPxfHM

[@gaetanperrier4305]

Hello, great video ! However, you fitted he main bearings the wrong way: the open side of the cage should be facing outwards the engine cases in order to receive oil from the oil gallery. No big deal though.

[@wednesdaykartingflyingclub8164]

@@gaetanperrier4305 you’re right. Good catch. Those bearings are still running with over 500 hours on them mounted that way. 😁

[@larrykorell750]

Excellent how to video.....but why'd you take the whole engine apart? For fun? Can't be for maintenance....I have a polini with 425 hours on it and only changed out the piston and rings....how many hours on this thing?

[@wednesdaykartingflyingclub8164]

Thanks Larry. Vittorazi recommends replacing the main bearings at 400 hours. I was at about 460. So it was mainly maintenance and curiosity. I was starting to develop a slight vibration at higher rpm’s. But I believe that to be caused by the clutch. To be honest, I’m really impressed with how good everything looked.

[@larrykorell750]

@@wednesdaykartingflyingclub8164 wow, the motor looked brand new! Great vid.....I've never seen a motor that old in such great shape...thanks for posting!

[@ramashiajairo7260]

How many kilos do you have? How much weight can the atom support?

[@wednesdaykartingflyingclub8164]

@@ramashiajairo7260 My all up weight is 105-110 kilos. I fly mostly around sea level and the atom80 works well for me on 18-20m wings. I know that there are heavier pilots flying the atom, but it really comes down to what elevation, size wing & flying style you have. Check with pilots in your area of similar size to compare their satisfaction.

[@martinberwanger4928]

Where I live , we don´t have mechanics in paramotor engines; to whom do you think I should ask for advice? A motorbike mechanic maybe? A karting mechanic? At least to make the normal maintenance of the engines...

[@wednesdaykartingflyingclub8164]

Yes. Both karting and motorbike mechanics would be good choices if they’re familiar with two stroke engines. Even some lawnmower/landscaping mechanics have the ability also.
