I wish my bike ran on LPG!

[Matt Bleck]

So could it be done.

I was thinking throw away me petrol tank and then steel the gas bottle out of the LPG heater while the missas aint lookin. Then get some poor bastard to sort out the rest!!!

But don't worry you won't read about some idiot blowing him self up whilst try to fill his LPG Gixxer at the gas station tomorrow. :rofl:

Surley someone out there has thought of it? The only problem that I can think of would be making the right shaped tank to fit in the bike without being obtrusive. Do LGP tanks have to be rounded, so to speak?

What ya reckon, yeah, or am I just :tugger:

[Jackrat]

LPG tanks get cold mate,,,REAL COLD.

[Motu]

Pity we sold our gas to the Japanese for a quick buck eh? I got a Gas Instalation Certificate around somewhere,but haven't done a conversion for over 20 yrs,maybe I could experiment on someones bike?

[NordieBoy]

So there will be no need to stop at pubs on a ride out.
The tank bag of stubbies will be sweet :D

[Mr Skid]

maybe I could experiment on someones bike?A dual fuel dual sport perhaps?

You can become sterile if you want

Bwahahaha, at least you'd take the cager that ran you over with you

Very tallented guy by the name of Stu Ploughman from Wellington once converted an AX100 to LPG. He's also credited with building a converter to tune Jet Skis on a Dynojet rolling road and making a fuel injection system for an 89 GSXR400. Tragically killed at that cunt of a 45kph bridge between Featherston and Martinborough.

And that would be bad?

[R6_kid]

surely it could be under the seat or something like hte Suzuki impulse (used the 'tank' for storage).

How difficult is it to do? Does the engine need to be modded or is it just the fuel intake?

I am no expert on this but our van is on LPG. Dual fuel carb L300. It has a mixer that feed the mix in to the conventional carb,but I assume if you have fuel injection it would be possible for a bike. The tank is going to be a problem and the van doesn't go as many km per litre on LPG as it does on petrol so the range will be less. But it could be done. LPG is a great fuel and burns clean so tuned right it would run well.

my experience of slamming nuts into tanks - u hit at some force (put a nice dent in my last tank that i did this, then i couldnt walk......apparently due to my leg, but i wonder).
I would hate to detonate a bomb by doing this :dodge: although it would a good way to go out, with a bang and all :lol:

Hey dude.

I think the only problem with an l.p.g rigg would be the slight drop in engine performance as the bottle begins to empty. The pressure inside the bottle will drop. As this occurs, the amount of kinetic needed to push the gas particles from an area of high concentration. To an area of low concentration. Will become less. alot less.
This will effect the flow rate of the gas which will also affect the amount of gas mixing with the air. Which could mean a lean mixture.
You'll have to jack up the compression. Fit solenoids, hoses and the tank...
The tank might not go down well. The way that it is now.
They could try manufacturing a special bottle. But this will be subjected to rigorous safety approval and hours, weeks, or months of stress testing.
The tank will also add a little bit of weight to your bike.

But nevermind all that shit bro. I've seen anti-gravity in full effect.
Gyroscopics, mono-atomic gold, superconductors, even a synthetic material.
That has the same density as air.

Hmmm. I might just put the knifes on. :doobey:

I did on Tuesday morning. Didn't take an LPG conversion either. Just a doctor, a blade, a thing like a crochet hook and a mini mig welder. Didn't hurt bugger all either.

Sure an Lpg bike would work fine. But when you 'fill' a lpg cylinder you are not completly filling it with gas. An lpg cylinder has 80% of its capacity filled with liquid petroleum gas, then the remaining 20% allows for expansion of the cylinder contents due to outdoor temperature change. Inside the cylider has two valves, like your bike tank except from the top instead of bottom. One outlet for the gas as it is drawn out to be put through the carbs or out into the BBQ. The other is the overflow, so should the contents over heat or be over filled then the valve will allow the excess to escape.
There are 2 main problems, when you are riding liquid inside the cylinder may end up where it is not supposed to be, liquid through lines instead of gas and out the overflow. The second is leaks, apart from the obvious explosion risks. When the gas is released onto skin it almost instantly freezes it solid. Something i wouldn't fancy happening between my legs :nono: . I have had Lpg leaking onto thick 'approved' gloves and its still quite uncomfortably cold.
Apart from that i don't see why it wouldn't work, would be pretty clean burning, less likely to be affected by petrol prices and no doubt 'different'.
It's been a while since my course in lpg but i'm hoping i remembered some stuff right.

Na mate, LPG sounds way too easy. Make your bike run on water, and make sure the only waste product is beer or rum. Then you will be the man :clap:

The only problem that I can think of would be making the right shaped tank to fit in the bike without being obtrusive. Do LGP tanks have to be rounded, so to speak?The tanks tend to be circular due to the inherent strength of the shape. It would be difficult to get away from this due to the high pressures inside the tank. :violin:
