Be working on my bike the last while doing various stuff and had the tank off and on a few times
So I will try and be brief
Normally when I lift the tank and remove the lines fuel will come out the vent pipe (if I remember correctly it eventually stops) but I normally just put a small pipe over it with a screw in the end to seal it and stop the fuel coming out - so far so good everything normal
The last time I put the tank on I forgot to remove this little pipe so the breather remained blocked for a short time, it resulted in fuel starvation and hesident throttle when I opened it - no worries I checked and there was my little blocking pipe still connected so removed it, everything seemed ok but not fully tested on a long run
After that I had to remove the tank again and noticed something different - no fuel came out of the vent pipe which I thought was strange and unusual but didn't give any more thought
A couple of days ago I was on a long run 150km and during that time I suffered from fuel starvation - open full throttle and it started to hesitate for a short time tank was about 1/5 full, I filled her up with fuel as normal and didn't have this happen again on the return ride back home, doesn't mean it won't happen again and shouldn't have happened in the first place.
Does anyone know how this vent system actually works inside the tank - could I have damaged something by not removing my little blocking pipe - could there be fuel in there blocking the vent because I didn't remove it and rode the bike a short distance.
So basically how does this vent work - I know something had changed since it didn't drip fuel the last time I removed the tank (before the long ride)
How does this vent thing work ?, is there a pressure/one way valve that I may have been damaged by not removing my little blocking pipe and going for a short ride, I know there is an overfill at the top of the tank beside the filler but that is something entirely different
Anyone know how this vent actually works and what it is connected to inside the tank
