What a blessing

I have done the conversion and what a blessing! Saving a lot of money. Running 6 months on a 19kg gas bottle.

Ryobi Generator

One of the best convertions to save money. Gas usage much cheeper than petrol. 21 hours running time on a 19kg gas bottle with still a little hit of gas left in the bottle, but not enough pressure to keep generator going. Use gas left on gas stove for value for money. Easy to install with step by step guide given.

Great product for Ryobi

Great support and fast delivery.
I fitted the GX-390 to my Ryobi RG-6900K and it runs beautifully with no settings changed. Easy to fit with good instructions and a video on their website.
Extremely happy with my purchase.

What a saving!

Many thanks for both excellent service and an awesome product.

I received excellent advice when phoning to query the gas conversion, and on placing an order received prompt delivery.
The instructions to fit the new GX-390 Dual Fuel carburetor were clear and concise and very easy to follow.
My Generator (6500 Watts) started immediately on Gas, and certainly runs cleaner.
Running on Petrol cost me R 61.60 per hour, on gas it is costing me R 23.84 per hour. A saving of R 37.76 per hour.
I'm a very happy customer.

Running so quietly!

Good day, Gasgen users
Today on the eve of women's Day celebration 🍾 ✨️, I received my Conversation kit GX390 dual carburetor. I installed it so quick But to I somehow struggled to get it started due to overflow gas into carburetor. Eventually, I figured it out, Wow 👌 👏 😍, I ❤️ love it as running so quietly and, this time No Petrol! What a day! I can't wait for stage 5 to see how far will it last with 10 kG cylinder bottle. Thank you so much Mr. Gordon. Your service was world glass and assist.
