I want to put a bigger fuel tank, preferably 25 litre one or more on my 1978 bull. Cos I think the current 17 lt tank is too small for touring. The one thing that has prevented me from making the change in the past is this fear -- will the bigger tank affect the stability of the Bull?
I have been in Mumbai for nearly two weeks and I have seen Bulls with even 30 litre tanks. Bull experts help me out here!!!

I have never ridden a Bull with a bigger tank, but seeing the number on the roads (making long distance trips) I doubt stability would be an issue.
I think the main concern for tank size upgrading remains leaks and poor finish.
The current one would give you a range of at least 400 kms in any case, unless you plan to tour Leh/Ladakh and not use spare canisters, why exactly do you need the longer range?
Cheers!

The best way to avoid stability issues with a large tank is to have baffles inside it.

I cannot be more right than BBlost, anyway, just thought of adding my 2 cents on your requirement on bigger fuel tank

Though these are only 25 lts & not your requirement of 30 lts, it should satisfy your requirement to an extent.

@BBlost - In your pic above, how does the fuel flow from one compartment to another? Are there small holes in between the baffles?

[bblost]

aargee that is just a sample pic of a baffle tank.

Its not even a Motorcycle tank.
Attached for illustration only.

The walls in a baffle tank, don't extend all the way to the bottom.
This limits the force with which the liquid inside will jump around.

I personally don't think we need a tank larger than 20L for India.
At a conservative milage of 25 kmpl, A 20 L tank gives a range of almost 500 Kms.
Its very very rare that you will not find a petrol bunk at that distance range.

Plus one can always carry additional fuel in a jerry can. That can give a backup range of almost 100 kms.

So guys where can I get big tanks with baffles???
I am planning a trip to Mizoram, that is if things fall into place, so a big tank will be quiet handy!!!

Got you; I definitely agree that, if the fuel is allowed to move freely within the entire tank, the balance is lost; probably that's the reason why a stock HD also doesn't have more than 5.5 gallon tank

Very valid & I can understand this engineering.

Agreed 100%

Yes; the largest distance between two fuel station, atleast that I've heard is between Tandi-Leh which is 365 odd Kms.

Baffles or non baffles, you may want to check out the link I sent; they're selling the tanks for quite sometime now.

Good luck & do not forget to share the travelogue as there're less people travelled over NE states.

[COUGAR]

if it is one of those crappy ones from Karol Bagh then forget it bro.

i borrowed a friends 22 liter tank (KB make) just to get the feel and i didnt like the changed dynamics one bit! When fully tanked up the bikes handling was a beeaatch!

the baffles idea is intriguing though. Anyone tried it?

@Leepower,

I don't think it would affect the stability of the bike but think of the turning angle. Some places like Leh it might become little tight, again this is subjective to riding style and location you are driving.. other than that i dont think you would face problem

But 17 L should easily give you close to 400 Kms.. what route or tour do you need this tank for ?

cheers

[Leepower]

I am planning to ride the Bull from Pune to Mizoram. The Shillong-Aizawl route is where a bigger tank would be a blessing cos fuel stations are far and wide!!!

Mon amigos,

I'm planning to modify my RE electra 2005 totally into an Indian Larry's Grease Monkey kind of a chopper.

Well.. To start with I was dilemmatic whether to completely restore it or to go chopping. Just that, since an RE electra 2005 wasnt exactly my idea of a classic, I've decided to go ahead with chopping it.

Now I have my design on the drawing board almost ready. The last remaining link is the petrol tank. I wanted to go for a Mustang MC gas tank. However, I like the 17 and the 20 liter RE aftermarket tanks too (i'm a tad inclined towards the 17L one). Anything bigger than a 20 looks down-right ugly to me (like "the just doesnt fit in there" types).

Given all the background, I found some gastanks with a grill (like the one shown in this very picture). I want to know the function of this. As I'm looking forward to build a bare-bones chopper, anything that's not functional shall be "maro goli".

Can someone tell me what the function of this grill is???

Pleeeeeese!!!

Greetings,
Rhoads!

[john doe]

The grill is purely a show detail, nothing functional really.

If you want to sell your old tank, let me know. I am looking for a regular tank for my bike.

Thanks!

[Rhoads]

Thanks, John Doe!

I'm not exactly going to sell my petrol tank unless I source a mustang (saw this somewhere online.. costs about 14 large to ship it to India) or a "good" 17 L tanks on the roads of Bangalore.

If I am able to source one, I'll put you on top of my list. You can just pick it up for free!

[john doe]

You know, there are a lot of suppliers of Enfield and custom made tanks in Delhi. Try them maybe they can make one for you as per your design.
Thanks for the offer of the tank, very cool of you!
