Movistar Yamaha's Maverick Vinales showed signs of frustration after the final day of MotoGP testing at Buriram and admitted he hasn't felt good on the YZR-M1 for six months or more.
The Spaniard finished eight-tenths of a second off the pace today after competing 71 laps and is half a second slower than Dani Pedrosa on the overall sheets.
"Honestly, it has been very difficult, the same as Malaysia, we haven't figured out what is the problem but anyway we are trying to work hard and we are going to continue trying to find where we have the problem. The most we have is on the braking, so we will see," said Vinales, speaking at the track.
"We have to improve all areas, the rivals have made a step. It's difficult to make the top ten when things didn't go in a good direction. From yesterday I think we improve nothing.
"It's six months I haven't felt well on the bike, many races we have the same problem ans we haven't found out yet. As a rider I cannot give my best and you can't be satisfied. For sure I am worried as the race days are coming fast and we only have three days in Qatar.
"I don't know the solution, I am not the technician. For sure I will continue working and when the bike is ready, I will push."
