Hi. This is my first post, except from the introduction...

I have an issue with the bike (2007).

The bike did not have any of the tank breather - drain hoses when I bought her.
I've installed the hoses and route them to the original place, next to the gear selector...

The issue is that if I park the bike in the sun, the breather hose drips fuel. Now when I say drips, it's very little. Let say one drop every 20-30 minutes, but it doesn't stop until I put her under shadow, and then It stops...

Bare in mind that I removed the cap and clean it thoroughly.
If i blow air from the breather hose to the tank, it hissing from the small hole in the cap (see pictures).
If i remove the tank and close the hole on the tank and blow air it does not lose pressure...

Is this normal???
I did not have this issue with any of my previous bikes...

Sorry, if this was answered before but I couldn't find the exact problem...

PS. The pictures show how much fuel was down after 4 hours under the sun https://uploads.tapatalk-cdn.com/20190419/7b4d1264e130763eff6f59141e6f3fe7.jpghttps://uploads.tapatalk-cdn.com/20190419/7887d1a2957eb824fa025ce00b9e8e69.jpghttps://uploads.tapatalk-cdn.com/20190419/85c2ff632283947c63ef1c5cf62aec51.jpghttps://uploads.tapatalk-cdn.com/20190419/11e56033c3c39617b703ec0830481424.jpg
