EX500 Fuel Reserve Question

7005 Views 13 Replies 8 Participants Last post by  Narcisse91
The EX500 fuel tank is supposed to be like 4.8 gallons. I think there is a 1 gallon reserve.

Is that 4.8 gallons total, so 3.8 gallons main?

When you fill the tank, it fills the reserve automatically, when you use the gas, it uses the main and doesn't touch the reserve. So, if you never use your reserve, that gas just sits there and gets really old?

Hmmm... That makes sense.

I had to use my reserve for the first time in about a year last night, and I had a hard time getting the bike to run on the reserve fuel (it wouldn't idle right, or die as soon as I got on the gas). After about 5 minutes of fussing with it on the side of a highway at 11pm, I finally got it running.

I assumed I had all this trouble because the gas was seperated and old. Any other reason why it would act this way on reserve? Last time I used the reserve, it fired right back up and I was on my way.
Yeah, I remember reading that thread, but what Curt is saying is the opposite of what QKENUF4U is saying. What Curt is saying is similar to what happened. But I read somewhere else along the lines of what QKENUF4U said.
I just asked someone I work with about it as well, and he said the same thing, the tube may get clogged, but the gas should be the same.
Well, it wasn't that I didn't realize I was running out of gas, but the first time I felt the lack of power was on a highway on ramp, with the next exit 3 miles away, so I tried to go for it. Unfortunately, I fell about 200 feet short of the 1 mile away sign.

Last time I felt that first hesitation (previous tank of gas), I made it all the way home from work, about 15 miles without using the reserve.

Either way, it could be the empty carbs thing, since I definitely rode until they were dry.

If you were to accidently run it dry - just prime the gas petcock - switch to reserve and let her rip. As a practice I use my petcock and switch to reserve every now and then when I think about it and just avoid the issue of having blockages with a little preventative maintenance.
Well, I think that's what I need to do. Use reserve now and then whenever I think about it. I usually keep the tank somewhat full (above halfway) just so I never have to think about it, so even if I flip to reserve at the first sign of low gas, it still may only get used once or twice a year.
