This can't be normal? Is it? Any advice?
no we ride two up alot and i havent noticed much if any drop in my mpg
100 mi until reserve or 100 miles including reserve?
that shouldnt matter when we ride 2 up 200 +/- a few to res.
i....dont have reserve.
You should. Do you have a knob on the left hand side of your bike? It should say res, Pri, and On. I've never heard of a GS that doesn't have a reserve I mean you can alter the petcock but I still don't think that get's rid of the reserve!

I could see 100 miles to reserve, but not 100 miles to empty, unless you aren't filling the tank all the way up, which is pretty easy to do.
Nah, eliminated the vacuum on the petcock and yeah, I filled up a few days ago, trip meter was at 301 and bike started doing the perculator at 401. Ben2go, you want to chime in; i thought the reserve was eliminated with the mod that was done to the petcock.
so your only getting 22.2 miles to the gallon? your dumping alot of fuel somewhere

Doesn't the '90 gas tank hold less than the later ones?
yeah 4.5 in the 90's models
4.5 into 100 = 22.2
Keep in mind josh that I have the same tanik you have. I've done the F conversion on my 90. Which has it's draw backs because I swear theres atleast 1/2 gal left in there that the carbs don't get.
oh sh!t you have a 5.3 gallon tank your getting worse then i thought. 18.86 mpg
Sounds to me like you're only hooked-up to the ON side of the fuel valve at the tank. That would give you no reserve. The bike would run out of gas with a gallon left in the tank. Your bike is still sucking gas like a car though. 14-tooth sprocket and you never go past 4th gear?
Stock sprockets with 150s and wileyco pipe, srinath flange and lunchbox. I always smell gas but never see it. I'll definetly have to look into that.
How did you do the mod If you only have a shut off valve then you should be hooked up to both ports on the tank then into a SOV then into the carbs. if you did the epoxy and turn the insides of the stoker than you set up should be om reserve and off. you may have did something wrong
You've told us that you ran the tank to "empty" but how much gas did you put in it when you filled it back up? I'm betting on a combination of "not hooked up to reserve like you thought" and "not filling the tank all the way" here, that could easily account for all your problems.
yeah but even if he is filling the tank to the neck and no more, he should still be going for more than a 100 miles. Average your gs eats more gas than my GSXR and that just ain't right.

Eh, when I first got my '94 I wasn't filling the tank all the way (filling on the side stand, filling to the filler but not waiting for the tank vent to let the air out) and also riding poorly (35 mpg, lots of high revving and stuff, I was new) and I would go 100 miles and hit reserve. Now I get way further by filling on the centerstand and just riding with better technique. My mileage average has gone up 10 miles per gallon through smoother technique alone. If you under fill the tank by just a half gallon, you're already loosing 25 to 30 miles of range....
Its getting into the filter on acceleration. Check, clean and set floats at a minimum.
Man we need to poke the werase into a get together.
Cool.

that's pretty bad mileage.
underinflated tires? :dunno_black:
ridin' the brakes? :dunno_black:
Just filled up again today. Ill let you guys know again in a few days if anything has changed.
Budda's right. The "I smell gas all the time" is the giveaway. Two causes for that. #1 leaks, which are obvious, or #2, your floats are too high causing your carbs to overflow, soaking the filters.

fill up to the NECK, ride 50 miles, fill up again. record how much gas it takes to fill up to the NECK again.
i'll bet you've got some weird blockage at the bottom of your fuel spigot tower, or whatever it's called.
got 142 out of this tank. Josh, the tank maybe 5.3 gal but there's no way it holds that much. I've yet to spend over $7 filling up my tank.
you may not think it will hold that much but your still only getting 26 miles to the gallon. even if we say 4.3 your only getting 33 mpg and for the gs thats not even close to good.
how many gallons did you put in the bike at fill up?

@ $2 a gal assuming - you're ~40 or so for a $7 fill up. Not the best, but I can see that if you have over 20-25K.
You may still ahve high floats though, smelling gas = giveaway.
Cool.

i'm at 26,669. Still not bad for a 90 but i definetly have to figure out what's up with the gas mileage.
Buddha, he's still smelling gas? I told him that was a giveaway. Act on it! Your bike is leaking gas, either from the carbs, or somewhere else. Find it!
30,000 miles isn't excessive. Unless you ride like an asshat you should be getting 50-55 mpg minimum. I got pulled over for speeding twice in the past several months and I average 61mpg! (got let go both times because they dug my bike!) :thumb:
bill are you sure they dug the bike maybe they couldnt beleave it actually got over the speed limit. you know with it being a little ol gs an all :technical:
Average - also worth checking is brake drag, as well as if you have a different set of tars, that make it read off. Else the dunping of gas in the air filter is the culprit.
Cool.
