I was thinking about converting my 06 Suzuki Eiger to LPG, a dual fuel conversion, vapor system cause its an air cooled engine, the rear rack is plenty big enough to mount a LP tank and brackets, I have all the parts needed and the know-how I have a Impco fuel regulator and a CA55 carb mount with 1 1/2" opening. Question? Has anybody converted their atv to LP? The only problem I can think about is im going to make it a dual fuel system, where it can run on gasoline, or LP, not both at the same time, I need a fuel shut off solenoid to mount in the fuel line between the gas tank and carb, the solenoid is big and it doesn't give me much room to work with, plus its a gravity feed system. I was just wondering if anybody here did the same conversion im talking about and may get some helpful hints. Thank You

 

I've heard a lot of ideas before, but this is the first time I ever heard anyone come up with an idea like this. Maybe it's been done before, but I doubt it. It seems to me that there's a serious safety risk of putting a propane tank on the rear rack of a vehicle that is likely to roll over at least once or twice in it's lifetime. Good luck with whatever you decide to do.

 

20 lb tank filled with propane weighs in at 42 lbs
plust the extra hardware you are adding a ton of weight
also LPG doesn't make the power in a motor designed for gasoline
the range is very limited fuel economy is less
why do you want to do this anyways?????

 

I wanta do it cause I have all the free LP I want, the nearest gasoline station is 6 miles away, its a hassle running that far for gasoline plus LPG burns cleaner, good for the enviroment. Im one of the few, or only member of the Pennsylvania Serria Club that owns an ATV. The LP tank on the back weighs 72 lbs when full, and the tank is made from a non-sparking metal.

 

I have never heard of this in the atv world but I have seen a lot of it in the Toyota rock crawling crowd. A lot of guys got to propane because of the advantages of it over gasoline in a carb. at extreme angles VS going to a FI system. But at the loss of power. Like recon said I would be worried about the explosion factor here...even if your tank is spark resistant there must be some sort of line coming off of it that could be easily broken off in the even of a rollover. And adding over 70 lbs to the rear rack sounds crazy to me. I would just drive the six miles and buy gas if I were you instead of loosing power and the chance to explode, but that's just me, good luck.

 

SFA - i will bite - might regret it but what the hell - what is SFA??? see in your photos that you list your vehicles with SFA in front of it.

 

Here is an idea. Go down to the store and buy 5- 5 gallon plastic gas cans. Take them to the station and fill them up. Now you have 25 gallons of gas to use in your quad without the risk of breaking the hose bib off of the tank. By the way, just because the tank is made of non sparking metal means nothing to me. There is several pieces on your quad that isn't.

on a LPG system there are many saftey items, starting at the LP tank it has a plugging valve incase a hose would break, it also has a relief valve incase the tank is overfilled or heats up, the LPG hose is a non spark producing metal braid hose, if its cut or broken it won't spark, plus its grounded from static electricy. fuel going to the fuel regulator first goes thru a solenoid operated shut off valve, that has an insulated ground incase of an electrical short. I won't skimp on the saftey items. I can get all the LPG I want for free plus gasoline keeps going up in price, LPG burns much cleaner , cleaner eviroment, with LP never have to change the motor oil, it never gets dirty, and the spark plugs last forever, no carbon deposits, the only drawbacks the engine will run hotter and run with less power. I wanta be the first my area to have a LPG ATV, when im done, I will send some pics, I need to order tank brackets, hoses, and carb air intake hose and clamps. Im going to run it dual fuel, start it on gasoline untill the engine warms up, then turn the gasoline petcock off, let it run untill it completly runs outta gasoline, then turn the toggle switch on to produce ign volts to the LP solenoid and start that baby up on LP, then when I switch it back to gasoline have to run it outta LP first, just turn off my LPG toggle switch untill the engine stopps, then turn my petcock back on. You have to run it outta one fuel first before you run it on another fuel, won't run on both at the same time.

 

MotoF150 the reason i said what I said was because I did not want to see you get hurt with this deal. If you are going to put all the safety equipment in place then more than likely you won't have any problems.
The only big problem I see is space. Your now going to have to put a mixer and a carb in one space. I don't know where you got the regulator but a lot of gen sets run on LPG and are sized about the same as an ATV engine. If you have all the right parts all you need to do is hook er up and have fun.
Please double check hose routing and make sure everything is good to go before you light this thing off.

 

The LP system will use the existing gasoline carb, I have an LP adapter that fits in line with the air cleaner hose as close to the carb as possible, the mixer, regulator will be mounted close too, but it will be mounted away from any heat or exhaust areas, Im using a UL Apporoved LP hose that will be grounded properly. Im all excited about getting it done, im going to be the first one with a LPG powered ATV, can't wait to show it off, I can take some pics if you guys are interested.
