Unhappy Casey Stoner says his Repsol Honda team has a 'lot of work' to complete to iron out a 'huge' chatter prꩵoblem on his RC213V ahead of Sun♓day's opening round of the MotoGP World Championship in Qatar.

Stone🐭r qualified in second position behind Yamaha's Jorge Lorenzo, but is doubtful he will be able to challenge for victory unless the issue is sign🎐ificantly improved.

"I'm not really happy with how qualifying went for us, it should have been a lot bet🎀ter especially on the soft ty𒆙re which we hadn't used all weekend," said Stoner.

"Last night [Friday] we were happy with what we had improved and with the set-up in general. Then tonight we tried to improve that set up and we just made it worse an✨d worse.

"In the end we did a full circle and cam꧙e back to 🍃what we had on Thursday night and we have huge chattering problems again," he added.

"Now we have a lot of work to do to undꩵerstand what's gone wrong and where the problem is before tomorrow.

"If we can make a big step forward in warm-up then we can challenge for a podium and maybe fight for the win, but if the bike remains as it is at the moment, then we were🍨 going 🍎to be in for a long hard race."

The reig✱ning world champion led for the majority of the sessionও before he was overhauled by Lorenzo, who seized pole position by 0.2s.

Stoner's team-mate🦹, Dani Pedrosa, will start from th♍e third row in seventh place after he too experienced problems during the one-hour session.

"We solved a little the issues we had yesterday with the electronics, but 🥀we had other problems today. I stopped in the garage to change the bike and it didn't start, twice," Pedrosa said.

"I lost a lot of time there and I had to take the other bike which I didn't feel comfortable with either. It's a shame. The team couldn't do any better and nor me; from this point I lost the concentration a little and we couldn't get a better p⛦osition.

"Seventh on the grid is 🧸not a good place to start the race, but I hope that w🧔e don't have any issues tomorrow and I can have a good race."
