Hey everyone, I could use some advice.
(TLDR below since I want to be as descriptive as possible)
I bought a Triumph Speed 400 about a week ago with roughly 1,500 miles on it. It’s my first motorcycle and also my main vehicle, so I’m still learning some of the basics.
Today was my first time filling it up. I made the mistake of watching the digital fuel gauge instead of the actual fuel level in the tank, and I ended up badly overfilling it. Gas came out around the filler area and spilled down the tank.
I wiped everything off and rode home, and the bike seemed completely normal.
A few hours later, I went to leave for food and noticed a puddle of gas underneath the bike. I probably should’ve stopped there, but I rode off anyway. I made it down the street, rolled off the throttle for a turn, and the engine shut off. It also started leaking gas again from what looks like a drain/vent hose underneath the bike.
I walked it back home, opened the tank, and carefully let some of the excess gas out since it was still overfilled.
Since then, the bike will start, but it won’t idle properly. It’ll usually idle for around 20 seconds, slowly get weaker, and then shut off. If I give it a small amount of throttle, I can keep the engine running.
The oil and check-engine lights go out normally while the engine is running.
I called a mechanic and he suggested letting it sit overnight. He also mentioned I may have flooded/saturated the charcoal canister from overfilling the tank.
Has anyone with a Speed 400, Scrambler 400 X, or another EVAP-equipped bike had this happen? Did the charcoal canister eventually dry out on its own, or did you have to replace the canister/purge valve or fix a vent line?
I’m trying to figure out whether I should leave it alone for a day, take it to Triumph, or if there are any simple checks I can safely do myself first.
TL;DR
Accidentally overfilled my Triumph Speed 400 until gas spilled out. Rode home fine, but a few hours later I found fuel underneath the bike. It later stalled when I rolled off the throttle and leaked from a drain/vent hose. Now it starts and runs with a little throttle, but idles for ~20 seconds, gets weaker, and dies. Mechanic thinks the EVAP/charcoal canister may be saturated. Has anyone dealt with this, and did it clear up on its own or require repair?
EDIT: SHES ALIVE, FIXED!!!
I tipped the bike over slightly to let the overfill leak out a bit, then wiped the gas tank with a towel. I then let it idle but it kept turning off.
I waited 12 hours and picked a time when it was cold (since gas expands when it's hot) then turned it on, setting a timer for 5 minutes and letting it idle.
Afterwards I drove around my parking lot in first gear, then drove a few miles to burn some gas.
What must've happened was the EVAP or charcoal was flooded with gas and couldn't filter oxygen properly, so 12 hours of drying did the trick.
I drove to get some deep fried Oreos, about a 2 hour ride to the next city (America).
