<{POST_SNAPBACK}><div class='quotemain'>When has it been a problem this year. Today was just a mistake by Rossi which he has admitted and earlier season problems largely due to michelin tyres rather than cooling problems in the bike.
I think the tech 3 both had a problem with the dunlop tyre not being able to withstand the heat today.
It was a problem on 990 but with new chassis for 800 would think it has been sorted.
Its a problem
Yamaha rider Valentino Rossi struggled with rising water temperatures before falling on lap six while trying desperately to get into clear air.
Team boss Davide Brivio said Yamaha were aware of the temperature issue.
"Overheating is a problem we know we need to work on," Brivio told Italia1 television.
"Our engineers know about it, so we hope to find some solutions. We have some ideas on how to solve it, so we hope to be able to implement them.
