Author Topic: 15.5L Safari tank fuel levels  (Read 18690 times)

Hi,
Yep its a big tank so most of the time we don't fill it, but how much fuel is in the sucker, after all, there's no gauge!
To find out I emptied mine and refilled in 5 litre increments to 10 litres. The interesting observation is the 5 and 10 litre levels line up with the top of the vent  holes.
The 5L level lines up with the top of the lower vent hole where it meets the tank nearest the rider and the 10L level with the top upper vent again where it meets the tank nearest the rider, see arrows on picture.
Also at the 10L level the fuel lines up with the back edge of the fuel filler (closest to rider) when looking down from above with the bike on level ground.
Hopefully this will give you a better idea of where the third or 5 litre levels are in this tank.
Also I found the reserve using the Safari tap set was half a litre.

regards,

Brad

So does this mean ya gunna be doin Timmy's Desert Ride (FULL REGO ONLY), or ya think it will have it's place on the Marysville cake shop run ??
I thinks it's a mobile service station (Ex-Xon Valdez)for those who HOON to much (TAYF) and run out of fuel.
Gee Brad you better stock up on zip lock lunch bags.

Pete,
Not sure the 250 is up to the Desert but would like to give it a try one day. To move on I am booking into Big Als school in March for a two year tune up! How long have you been riding?
Your right about some of the comments, yet they come from other riders I just write them up and no longer look like having a problem running out of fuel on the Reefton run.
It was one on Tayf's mates that passed on the Zip Lock bag fuel tip and it was the August 08 L2 First Aid training that passed on the body parts tip. Look forward to our next ride and your ride report. How is that new machine going, did it come with a 8L tank like the WR's? I could put the 8L back on for Marysville if I have time!

BTW I think the tank Dennis got off Tayf is a better size and fit for the WR250 as you don't need to do any modifications. Wonder what Dennis thinks?

Brad

The IMS fuel tank is a very good fit on the WR450. It is not much fatter than the standard 8 litre tank but now with 11.7 litres I can go a bit further. This tank does need YZ shrouds as the standard WR shrouds no longer fit. But once it is on with the YZ shrouds it looks pretty much the same as the standard set-up.....and I got a reasonable deal from Tayfun for the secondhand tank.

Yamaha went to great lengths to lower the center of mass of the new WR450.  They thought that even a litre of oil in the frame was too much so they adopted the interal oil catcher tank.

They were concerned about 1lt of oil.

You guys go and plonk and additional 3kg on the top of the bike.  It has to effect everything from suspension setup through to just general handling.  why not just carry a litre tank in your back pack?

Something else interesting is the 250 holds more oil than the 450.

Why don't they just design the bike properly in the first place with a decent fuel capacity!!!?Huh 8 litres is hopeless for trailriding and 1 litre in the backpack would still be light on for a decent ride. Extra weight on your back is even worse than in the tank as it is higher and you have to support it with your body..legs etc. The more weight you can transfer from your body to the bike the better, I recon. If I could find a decent way of fixing my heavy tool bumbag to the bike I would. Extra weight you carry on your body just tires you out more and quicker.

However, I have ridden my 08 WR450 with the 11.7 litre IMS tank full to see what it was like and I can report that I did not notice any top heavyness or fatness with the bigger fuel supply. It still works significantly better than the 04 WR450 that i had previously and it had 10 litres as standard. Even when half empty, I noticed no change in how the bike handled.

I agree that it odd that the 250 holds more oil than the 450. This just reinforces the need to change the oil often. My usual approach has always been to change the oil after 2 or maybe 3 rides, depending on conditions, OR at no more than 300 to 400 km. I only change the filter every second oil change.

What range do you guys get out of your standard tank in the high country?

On the 450 I hit reserve at 110 and can continue on to about 150.  Admitadly the last 40k's was going pretty darn easy on the throttle.

If I was a MX rider then I can see why all weight counts. It begs the question what is Yamaha's target AUS market and perhaps, I am on the wrong bike if it's not set up for trail riding in AUS. I see all manufacturers modifying their models for each world market because its different. Maybe the current top selling bikes in AUS have lost the plot and a newcomer will show the way for AUS. A litre of fuel on my back is good for 15K's and in AUS that's not far. On HCR08 only Sunday was an issue I hit reserve at the bottom of Schultz Tk and rode home. The 1 litre I carried I gave to a DRZ400 who was bone dry on the road just after I hit reserve. Also riding at altitude in the HCR vs down lower changes fuel performance and range. This is starting to sound like an age old discussion and reminds me of being in the outback with the 4WD, that is be prepared for all situations when remote for you and possibly others. If any trail bike can do 150Km between refuel's on throttle then that's what Australians need.

Cant see what difference another 3 kgs would make when the rider can vary that much between a large dinner, a few beers and a trip to the dunny the next day!

Yeah I agree with Brad on the fuel tank issue here, I have done many multiday rides over the the last 18 months with my Safari tank fitted it does look a bit daggy and does affect the handling of the bike when full however, this is a minor problem compared with running out of fuel and putting the bite on your mates for some fuel to get you home, if they give you some!

The majority of the riders weight should go through the foot pegs (if he's standing).

I do agree about the fuel range issue.  EFI doesn't seem to address it either with most manufacturers providing even smaller tanks to allow for the fuel pump, and they have worse fuel economy.

Did you consider one of these options, I like the fender tank.

Chris,
Did look at some of those options but its even more hassle in lots of ways. I used the KISS principal and have only ridden with it full once to see how it handles which as Wade said is heavy. So mostly I put 10L in and sometimes 12 if its more goaty or longer K's.
Soon I am heading on a trip that should do abot 150 to 180K's in a day. Everyone going has a big tank for this except the two XR's and a KTM300. May trade some more fuel for more free beer!

Cheers.

I bought an IMS Tank which at close to 12 litres seems about ideal.  I also wasn't a fan of trying to carry extra fuel in my backpack.  I already start with 3 litres of water plus extras so another two litres of fuel woudn't be much fun.  I figure the extra three litres in the fuel tank for the first couple of hours is OK.  You have to remember that once you use the extra few litres the bike is going to weigh the same as a standard bike anyway.

Also if the weight issue is so important why is someone of my body shape even allowed on a bike.  I am sure the extra few kilos I carry in the front can't be great for the centre of gravity.
