Has any of you guys removed the vacuume thingy from the fuel line? How about removing the lines directly off the tank?
Just remove the hose clamps (on the lines with them) and pull the hoses off. Watch the breather(?) line at the back, it's easy to miss and will break off if you try to remove the tank with it still attached. If memory serves me correctly there's 1 vacuum, 1 fuel line, 1 breather and an electrical connector.
What are you trying to do?
The owner before me removed the vacuume off the lines that go further down. I guess he said it was increasing the flow of gas or something. I was wanting to remove the rest of the parts from the tank, electrical connector, fuel and breather and just replace it with a high flow, it does have a bit of a problem starting now with just a little bit of fuel in it.
I'm not sure what the breather does but you could plug up the vacuum line, get rid of the electrical connector and put in a simple fuel valve.
I can't imagine you'll gain any performance or lose any weight...
Since it's my first bike with a fuel light, I think I'll keep mine ;D I'm going to get rid of the insturment cluster but will hook an LED up to the indicator wiring.
Yea, wasn't trying to lose the weight just get the best results from the fuel. Any ideas where I can get a replacement valve for all the in/out extra crap?
I'd be a little suprised if you can find a higher flow valve. Unless your building a top fuel dragster the stock valve will do fine even at high speeds. For example, if you look at the valve on a Hayabusa or GSXR10,000 it'll probably have the same diameter spicket.
If you really want to get more flow I'd start by gutting the stock one drilling the passages out. I think I'd get one or two off Ebay or a junk yard to play with... If you just want to do a test, get a gas can and some 1/4" fuel line and try driving it around like that...
I'd be surprised if you could get any more gas "flow". Even with flatslides, the gas isn't flowing fast enough where the hose is restricting it.
Just my $.02

You may want to check the fuel flow before you go messing with it, as others have already said. I've drained my tank by pulling a vacuum on the vac line using my MightVac bleeder. Doesn't take much vacuum to start up the fuel flow. And flow it does - the fuel hose popped out of the can I was draining into once and the floor was wet in a hurry. Fuel starvation could be due to other things - jets, empty floatbowl (if you let it sit too long - maybe), other things? I'm no expert on this, but those are some thoughts off top o'head.
