Esonnen, Cluby is right - it pulls out, but it may be in there sort of tight.

Since we haven't explained where it is - open the fuel cap on the atv. You'll see a white tube that goes down into the tank. The tube on my friend's BF750 just lifts right out. The tube on my 650 is pretty tight and I need to work it out. I usually have a heck of a time getting it out with bare hands, but I can work it out enough that I can get a plier on it and pull it out then.

I read it's in there to prevent overfilling. I imagine it also prevents fuel from sloshing around too much and having residual fuel come out the cap.

 

U guys are a wealth of information. Thanks a ton- I'll pass the info on to my dad.

rpxr400, many thanks!

I'm Esonnen's dad, so the questions were asked for me. I just went out and pulled out that little filler tube, and sure enough, it increases the usable size of the gas tank. I'll sure take advantage of that in the future.

Dumb question -- would it be a reasonable idea to just drill a couple holes in the filler tube so air could escape and that extra tank space could be used without pulling the tube out each time I refill the gas?

I'm pretty new to the whole ATV thing. Esonnen and his siblings bought me the BF 650 as a gift a couple years ago, and I'm too old and rickety to take full advantage of its capabilities. Heck, I don't even know how fast it will go, I chicken out at about 45 MPH.

This sure looks like a great forum.

 

there is no such thing as a dumb question. sounds logical! let us know how it turns out if you do it

 

Jsonn,

Welcome to the forum!! There is a wealth of information here.

I agree - it does sound logical enough that a drilled hole in the tube would enable you to get more fuel into the tank. I imagine the higher you drill it, the more fuel you can get in there. I know some people have taken it out and left it out.
I do like your idea, and I'll probably also do that. Then, the fuel will still slosh around less, and you can maximize the fuel tank capacity.

I have also never found out exactly how fast the 650 will go. I've had mine close to 60 on a nice flat surface, and I've heard they'll do 65+.
Sixty miles an hour on bumpy dirt roads is too fast for my comfort. Usually, when we get going on an open dirt road, we cruise anywhere form 30-45 or a little more.
Heck - I just realized last week the throttle stop is out about 1/4" on mine. I may not even back it off. It's got plenty of power for me.
