Home built four stroke Paramotor

This is a step by step photographic record of my home built paramotor. I based the design (engine) on the very popular 'Bailey' paramotors. I started by aquiring two 125cc scooter engines, stripped them down and machined what was needed to convert them for use in a paramotor frame. this may sound easy but it actually took me quite a long time. The pulleys were off-the-shelf items but may need to be changed to get the required gear ratio's correct later on. The paramotor is using a 1.3m prop. The wiring harness was made utilizing the standard scooter loom.
I built the frame using aircraft grade aluminium.
Once the safety cage is finished i will try a thrust test to see if I will need to increase the 'cc' of the engine, Bailey started out using 125cc engines but soon realized they needed more power.
I'll keep you up-dated.

No worries, you can contact me any time. Have a look at my other video as this shows the Mk 2, a much simpler and more efficient use of a GY6 engine.

Cheers, Steve.

The Gy6 engine has a massive range of after-market parts, that is the reason I based my project on it. Parts range frome big-bore kits, stroker cranks to fuel injection and even small turbo chargers!!! Nearly every Chinese 4st scooter has a GY6 copy powering it. Have a good look on E-bay, you might be suprised.

Hi Robin, to be honest it takes bloody ages to build something like this, but the way I look at it is Bailey want over £3000 for exactly what I have made for less than £500!

It may not be as pretty but who cares! I have just started on another engine to replace this one and hopefully now most of the R&D is done it should go a lot smoother. As for the reduction gearing, buy a set, it's the way I am going to do this one as I would like to use a serpentine belt in stead of 'V' belts and,,,,,,,,

@7275steve ,,,,,,when you take into consideration the time it takes to make these yourself it's just not worth it! Have a go I will always help out if I can. Look at some of my saved favourites the 'Yamaha four stroke paramotor' is a good one.

Cheers, Steve.

Great skills and workmanship ..well done ..

Hi Steve, what changes you made on the engine? Or is it stock?

Thank you SO much for this ..I've been looking at the GY6 for the last couple of days and I figured it would be the best for a paramotor (especially the price and the performance upgrades) my only worry was modifying the case (like the long case 150cc GY6's). I am going to download your vid off of youtube and use it as a template..you saved me so much time. I may have to message you if I have any questions but I'm making this a 1 and a half year project so i might answer my own questions thnks!

Very neat buildup sir ! This looks very promising, I am getting into a 4st project myself : 140cc dirt bike engine, fuel injected and supercharged to get 20-25 hp. I've been looking for the gy6 but it looked to have no upgrade parts and more limited availability in France. Give us some news !
