Larger Fuel Tank Options, Looking For More Distance Between Fillups

[callahanoffroad]

Not certain this is the correct forum to post in. Basically I'm looking for a larger capacity tank, or some other sort of recommendation. Basically my work is 45 miles away one way, and I intend to start riding to work in the spring after I get the bike restored again. I was wondering if anyone had any recommendations as to larger capacity fuel tanks or another option that would work. I obviously could fill the tank everyday but that would get a bit obnoxious. One thing I was thinking was to have a tank build that was larger and allowed for fuel storage throughout the entirety of the tank, possibly using two petcocks like I've seen on old British bikes. I dunno its 6 am and I'm just spitballing here. Any thoughts or recommendations would be appreciated.

You have approximately a 6 gallon fuel tank now. You should be getting over 55mpg. With a 6 gallon tank, your driving range should be 330 miles. I'm not sure I see the problem.

I guess he doesn't want to have to get gas every three days or so...

Any competent sheetmetal guy can do an "endurance tank". The trick is not having it look like crap. You can make it taller or wider, but then it starts to get in the way of your knees or the bars. Might be able to add to the bottom rear a bit, but probably not enough to make it worth while and lose the airbox.
If you want to keep the original lines of the bike, you'll have to do an aux. tank, either mounted on the tail or in the subframe. no option will be particularly cheap.

Yeah but that is not what the OP is saying. He says he is trying to avoid an EVERYDAY fill " I obviously could fill the tank everyday but that would get a bit obnoxious".

My best guess is the bike gets horrific mileage, he is unaware of the mileage it should be getting or has never actually checked the mileage. JTGS850GL has is right

[JTGS850GL]

If the mileage is not what it should be then that is where I would start first. Get valves adjusted, carbs cleaned and set the timing. Much cheaper then building a larger tank.

The tanks fitted to the UK spec 750 and 1100 are bigger and bolt straight on. Take a look on Ebay UK and you'll find one (don't forget you're looking for one for a GSX though - that's what they were called over here).

Thanks for the responses. When my bike was running I averaged about 42 mpg, and unless I am mistaken it is a 4 gallon tank on my bike. This winter I will be redoing the carbs, valves, gaskets, any electrical stuff needed. It went into storage about 2 years ago and i will be rebuilding it over the winter. I had no idea 16 valves should be seeing 55 mpg. I bought it from a gentleman in Danville Indiana back in 2008 (or there abouts) who casually rebuilt gs' s and came highly from this forum. He had gotten the bike into running condition.

Uh his tank is a 5 gallon tank and getting 55mpg would be cruising at 50mph. Bike has a cruising range of about 225- 230 miles depending how you twist the throttle. I average around 43 mpg on my bike and its tuned. I also live at 4,000 ft so that hurts the mileage some.

Your 42 mpg average is about right, though you have a 5 gallon tank. Don't trust the fuel gauge lol. And yeah only way you are going to get 55 is slow way down. Sounds like you have a maintenance project on your hands to get the most mpg out of your.

Dunno what went wrong there!

I've corrected the original post now as well.

Much cheaper then building a larger tank.

But not nearly as interesting.

[callahanoffroad]

I got the tank on the link. I couldn't find any specs on it. How large is the UK spec tank?

And yes I have quite the project on my hands. Mostly maintenance items, but I'll be doing some cosmetics as well.

[hampshirehog]

The UK tank holds an extra gallon I believe.
