NITROUS OXIDE ( nos / n2o ) advice forum

Hi ,could anyone tell me the full and empty weights of the new SFBK(2) for refilling?
Many thanks,

Dave.

The bottle holds 12 ounces or 350 grams of nitrous. Simply weight the bottle empty then add the nitrous weight and that's the full weight of the bottle. An empty bottle is around 640 grams. But I have to read my notes at my office to confirm this

An empty bottle is 625 grams from actual recordings.

Thanks for the quick response.so thats 625 with the solenoid included.

It's only the bottle and valve. No Pulsoid. You'll have to include the pulsoid weight.

Thanks,erm I do fill this like my old sfbk don't I?as in through the solenoid with 12v supply?

Yes, of course you can. As long as the end goal is the 350 grams of nitrous get in there.

Thanks for all your help , I wasn't 100% sure that it was the same to refill.
Big thanks sir.

You're welcome!


BTW, what do you use the SFBK's on, a bike?

Yes motorbike, currently its for my gs500k3 but have a 350ypvs that I've had since I passed my bike test 20years ago and have read on the website that its pretty cool using nitrous on two strokes!.
Am glad I found WON before one of them crap kits.

LOL I have first hand experience with nitrous two strokes! You should check out my Goped build! Link in my sig.

LOL ,didn't know that was you at first! I've been watching your bids at work(and working very hard!).you made me want a go ped now.out of interest how long to fill the sfbk2 nitrous bottle?

Big thanks again,but just one more question! My sfbk2 seems to work upside down.dose this mean no diptube and I can use it up side down?.thanks

There is no dip tube for the nitrous nor the fuel can, therefore it must be used with the valves facing down.
