American rider John Hopkins failed to meet his own expectations at Oulton Park with a ninth place finish his sole result from the Bank Holiday meeting.

Hopkins was a retirement in race one in the closing stages due to a misfire caused by a faulty sensor and scraped into the top ten in the second race on the Tyco Suzuki on a disappointing day for the Northern Ireland team.

"Unfortunately I can't say it's been a great weekend. I came in here with a lot higher expectations, as it is a track that I've always enjoyed," Hopkins said.

"I do have good memories from Oulton Park, but throughout the course of the weekend it never quite came together for us and I was never able to get into a rhythm.

"We had a few small mechanicals but I never really settled myself. This is a track that requires you to connect the dots and if you mess up one corner, you mess up the whole lap time."

The former MotoGP rider said he became frustrated after starting to lose ground on the lead group, which only served to compound his problems.

"When we got behind a bit I was getting frustrated with myself and I was trying to attack the track and this is not a place to attack as you make too many mistakes," he said.

"This can be one of the most physically demanding tracks or it can be one of the most enjoyable. Unfortunately this weekend it was physically demanding."

Australian Josh Waters finished 13th in both races and the Tyco Suzuki team will now be hoping for better results at the upcoming international road races at the North West 200 and Isle of Man TT, with Guy Martin and William Dunlop leading the line on the GSX-R machines.
