My fuel cap is making a lot of noise when I stop the bike, Had this before on a Ducati 848 and on the 848 there is a problem with breathing and they suck the tank in Does this happen to the blade and is there anything I can do to vent the tank properly?
I think I understand what you're saying...mine does the same though I wouldn't call it noise from the fuel cap...it seems to come from under the tank Not really concerned me to be honest. I think it's been mentioned on here before and the general consensus of opinion was that it is normal.
It is sucking air in. While it is doing it, if you open the cap you hear a rush of air go in. As if the breather is not working
Have a read at this thread...is it the same sound? I've the same bike as you and mine does it... https://www.1000rr.co.uk/threads/moaning-sound-from-fuel-filler-cap.31566/
yes that it it on the ducati 848 it sucked the tank in and ruined it , even on my little outboard engine if I do not open the vent hole it sucks the tank in. surely this is a breather fault may be another fault Honda will not admit
