Lakeside Hammers captain Lee Richardson has slammed his team's performance in Tuesday's 65-30 defeat by King's Lynn.
The Essex side were out performed in almost every department against the Elite League newcomers.
And 31-year-old Richardson, who had mechanical problems on the night, pulled no punches in his assessment of the trip to the Norfolk Arena.
"It was a disaster for everyone, those sort of performances are unacceptable for our team," he told BBC Essex.
"I've been suffering mechanical gremlins since the start of the season, hopefully we can sort them out fairly quick and crack on with our league campaign."
The Hammers hit the road once more when they go to Birmingham on Thursday, looking for their third win of the Elite League season after two victories on their home track.
And Richardson, along with co-promoters Jon Cook and Stuart Douglas, is hoping to move on from the King's Lynn display.
"We've got to put it behind us, I spoke to Jon and Stuart and apologised for the meeting, everyone has bad days," he said.
"We've got to move on quickly and I think we can do that as a team, we've got good riders.
"I think we've got to go and get something at Birmingham, I think the best remedy is to ride straight away.
"Sometimes sitting there thinking about it isn't the way to go to and we need to hit back extremely quickly and try and take some points from Birmingham."
