Re: gz250 mileage
 

I thought it was a 3.7 gallon tank with .7 as a reserve.

Re: gz250 mileage
 

It's 3.4 gal total capacity for the GZ250, 3.2 gal for the TU250.
And 224m/3g (before you hit reserve) = 81 mpg, which is still way over what most people are reporting on a consistent basis. What is advertised and what is reality often do not match.

Re: gz250 mileage
 

Service manual says: 14L(3.7/3.1 US/Imp gal) Including reserve.
Reserve:2.9L(0.8/0.6 US/Imp gal)

Re: gz250 mileage
 

Likely that he is already on reserve and doesn't realize it.

It has been a LONG time since we mentioned how the petcock lever is mis-leading.
I suspect that when he is out, there will be no recovery.

There is a tiny arrow on the lever that points to the active position; it is also the long part of the handle, which should "cover" the label for the position you are on.

He may not have it set on reserve ER, the other possibility is the tube fell of the petcock like it did on mine and was sucking straight from the bottom the whole time, (it sucks how you find that out too).

Re: gz250 mileage
 

WRONG!

The "tiny arrow" IS on the longest part of the lever, :roll:

Re: gz250 mileage
 

Your right, the arrow is pointing toward the longest part I went and looked. Pic is kinda grainy(cell phone) but its there.

Re: gz250 mileage
 

From the Suzuki site, (and I don't think the specs or size of the tank has changed), and this is what it said in my '99 owner's manual if I remember correctly--

Final Drive DID 520V, 110 links
Fuel Tank Capacity 13.0 L (3.4/2.9 US/Imp gal)
Ground Clearance 125 mm ( 4.9 in)

The number quoted here as 3.7 gal is in the service manual on this site and that manual is dated 1998. I don't know when or if anything has changed since then.

And let's not do this fuel petcock thing again forever - the LONG ARM points to where you want to go and it has the arrow on it. Look in the owners manual, page 7, and on multiple posts on here for diagrams and pictures. ER is wrong on this one (again).

Re: gz250 mileage
 

You are right as the back side of the petcock cannot point to prime.I read specs on 2009 ad.It has 3.7 and3.4 on the same page.It also states the G.Z. as having 2 valves insted of 4 valves. W.T.f.

Re: gz250 mileage
 

And the manual for mine (european) says 13.0 litres, 14.0 litres for Canada. Seems someone in Japan doesn't realise that a litre is the same all over the world. :oops:
