Do Acerbis tanks have this much of a problem emptying fuel?

Does this look right to you? How bad is that bend in the hose?

Going out for a ride tomorrow and hopefully I can get another 50-60 miles before it goes dry. If not, I might be putting the Safari in the flea market and picking up a Acerbis. I really need the range and don't want to carry external containers if I don't have to.

Looks like you have a "L" right angle fitting there, and then your fuel hose has to go UP HILL to the Carb. As long as you have a bit of fuel pressure (head) in your tank, it's likely you can use most ... but maybe not all of remaining fuel in your Safari.

QUESTION: Does the Safari not have a reserve? If not, perhaps you could fit a different Petcock ... one with a reserve intake that is LOWER than the current one in the Safari. This should give extra range.

Question 2 : Does the Safari have TWO petcocks? (right and left side)

I went through similar problems with my IMS tank. I also had to remove an inline aftermarket filter and had to rotate metal Carb intake pipe. All this helped, along with cleaning my dirty Petcock filter. But on your NEW tank should not be an issue ... yet.

I've retained the stock Carb inlet filter in the metal tube ... but I carry TWO
spares when on the road. One load of bad gas will CLOG this tiny filter ... so keep an eye on it. Usually it can be easily cleaned. Sometimes not, hence carrying a spare.

Now ... with my IMS tank ... I can go to about 220 miles before reserve. And what was once just 10 to 15 miles on reserve is now up to 32 miles.
Cleaning the petcock made the BIGGEST improvement. So now up to just over 250 miles until DRY. (although still about a 1.5 liters left unused) Not perfect but better. 220 miles is fine for me and what I do. PLAN AHEAD!

Good luck!

Looking at my Acerbis4.9 tank, it appears that the petcock actually sits below the level of the intake on my carb. Anyone else notice this? I can't actually hook up the fuel line without there being a bit of an uphill climb to it or a bend.

Don't know if this could help, but... I have pressurized the gas tank on my ST1100 with lung power and piece of hose to get fuel to the carbs when the 'lectric pump failed. Not recommended for a long trip, and do remember to remove the hose from yur mouth before ya inhale.

Is this an IMS or Acerbis tank? Seller claimed to be acerbis. But look IMS to me. I think acerbis is more angular, correct?

I just purchased the acerbis tank and it looks the same to me. You will know for sure when you fill it up.

Then 5 miles from town in 108 degree heat, it stopped. It looked like I still had a lot of gas left so the only thing I could do was shake the bike a bit and luckily got some gas into the engine. Once at home I let everything cool down and I sprayed the carb inlet elbow with ALOT of WD40 and proceeded to empty the remaining gas into another container. When the Safari finally ran dry I found that it still had an additional 4 1/4 liters of gas remaining…and I was pissed. So I stripped the tank off grabbed a set of vice grips and cranked the elbow over to the 90 degree position. Was pretty happy that nothing snapped off and after I put the tank back on I re-routed the lines and removed the cheap inline filter I installed.



This is what it looks like now.

Stay tuned and thanks again for your help.

This seems to be a common problem. When I fitted mine I had it the same as yours and when I hit reserve the bike would die even though I had changed to reserve. I had to blow down the tank vent to get fuel into the carb before it would go again.
What you need is a longer hose between the T piece and the carb and it needs to loop down and back up to the tank. This cures it. Straight in like you have it seems to cause an airlock. With the hose going down hill there is always some fuel in it.

My Acerbis tank is a 5.3 gallon. The petcock is above the intake on my carb, but I have a TM 40.

Thats the one on craigslist right, in spokane?

[Ren20]

Yea, Spoken with the seller. He confirmed it's an acerbis. Only wish He posted pictures of different angles.

Thanks I'll put a "loop" back in it.

if it's an acerbis, it's some older type...

Every time a new thumper comes out I get excited and think it might be something to replace the DR. Then I read posts like this. All that just to change the oil.

And I thought changing the oil on my old 520exc was a PITA. Love my dr though suspension no where near that of the old 520...
