Reigning MotoGP world champion Casey Stoner has being working to prevent a repeat of the arm-pump problem which cost him victory at the series opening round in Qatar by using the same methods he employed after Silverstone in 2010.

The Repsol Honda man won't give away what he is doing but it is believed to be dietary as he isn't going down the usual rider route of having surgery to release the the pressure caused by compartment syndrome, to give its proper title.

Since Qatar I've been working on the arm pump issue I experienced in the race and it's definitely feeling better. We've treated it the same way as when I had it in 2010 at Silverstone, so I'm hoping it won't be a problem for us this weekend," said the Aussie.

“After a difficult race in Qatar, I'm looking forward to Jerez. We had a very good pre-season test there; it's a track that hasn't been so good for me in the past so the fact we were able to hold a good pace there in testing has given us a lot of confidence. We still have some issues that we really need to resolve with the bike, especially the chattering in the entrance and exit of the corner. When we solve these we believe we will have a very competitive package."
