New bike, Two Persistent Problems (fuel system)
First of all, I'm a happy new '03 954 owner. I've been riding an F4I for a few years now, thought it was time to move on. The bike I purchased has 42k miles on it and is in great cosmetic/mechanical shape. Spent the weekend checking valve clearances, clutch wear, replacing chain and sprockets, (this weekend I'll be replacing the fork seals, thanks to a write up here) but there's two problems that persist;
After I fill up, get to my destination, shut the bike off and walk away for a few minutes, fuel begins to spill from the drain line off the charcoal canister. It's coming from the small line that connects the fuel tank to the canister. My best guess is that the tank is pressurizing and pushing fuel out somewhere. As far as I can tell, that line goes to some sort of ring near the filler opening. I'm not sure how it functions or it's purpose, but until the tank cools enough or the fuel level is low enough, it will continue to spew fuel out. I can, however, stand the bike upright and it stops. To add to the problem, the previous owner resealed the tank (and did a terrible job at that) and the sealant is all bubbly and looks terrible. So for all I know, that could be causing problems too. Or my other thought was that line has a small fracture in it (which basically makes the tank irreparable). I tried to "band-aid" it temporarily, and looped the small line up to the bigger drain line that allows water to leave the fuel cap area, hoping that gravity would keep the fuel spill under control, but it had no success. Fuel just came up over the filler cap and spilled all over the tank (and should it rain I'd have a tank full of watery gas!) And I'm afraid to cap it, as I assume that would vapor lock my tank...?
The second (and probably unrelated) problem, is the fuel light goes on and off intermittently. I'm going to check the harness for good connections and grounds, but figured I'd ask up here for suggestions.
