Unhappy Casey S𝓀toner says his Repsol Honda team has a 'lot of work' to complete to iron out a 'huge' chatter problem on his RC213V ahead of Sunday's opening round of the Mo𝔍toGP World Championship in Qatar.

Stoner qualified in second position behind Yamaha's Jorge Lorenzo, but is doubtful h🌟e will be able to challenge for victory unless the issue is significantly improved.

"I'm not really happy with how qualifying went for us, it should have been a lot better especially on the soft tyre which we hadn't used all week❀end," 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 and worse.

"In the end we did a full circle and came back to what we had on Thursday night 𒈔and we have huge chattering problems again," he adde⛦d.

"Now we have a lot of work to do t🀅o understand what's gone wrong an🀅d 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 reigning world champion led for the majority of the session before he was overhauled by Lorenz🅰o, who seized pole position by 0.2s.

Stoner's team-mate, Dani Pedrosa, will start from the third row in se𓄧venth place after he too experienced problems during t♕he one-hour session.

"We solved a little the i♎ssues we had yesterday with the electronics, but we had other problems today. I stoppe𓆏d 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 teaℱm couldn't do any better and nor me; from this point I lost the concentration a little and we couldn't get a better position.

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