Edward Kennett has been suspended and Coventry have seen their win over Lakeside Hammers overturned after the Bees skipper used an invalid silencer.
The match at Purfleet on Saturday ended in a shock 48-42 win for Coventry over Lakeside, with Kennett top-scoring with a perfect 15-point maximum.
However, both clubs confirmed after the meeting that appeals had been launched after issues over a number of silencers were raised.
But now the Speedway Control Bureau have confirmed that Kennett was found guilty of using an illegal silencer, and as such his points were removed from the meeting, along with three from reserve Nick Morris – who borrowed the bike in one race reports Sky Sports.
The means the actual score in the match was Lakeside 42 Coventry 30, and means The Hammers are now five points clear in fifth.
The SCB statement said: “The Speedway Control Bureau have issued an amended result for the Lakeside v Coventry Elite League fixture at Purfleet on Saturday.
“A protest was made to the Referee by the Lakeside Team Manager during the Meeting and another similar one was made by the Coventry Team Manager at the conclusion of the Meeting.
“These Protests concerned the validity of Silencers being used during that Meeting.
“At the conclusion of the Meeting, six silencers were handed into the custody of a nominated SCB Official, who on Sunday morning, in the presence of a representative of both Lakeside and Coventry had these examined by David King, the manufacturer of King Silencers.
“One silencer, that belonging to Edward Kennett was found to have been tampered with and therefore used illegally.
“The points scored by Mr Kennett (15pts) and those scored by Nick Morris (3pts) when using Mr Kennett’s motorbike in Heat 12 are deducted from the final score.
“Mr Kennett has been charged with non-compliance of the 2011 Speedway Regulations and a date for a Disciplinary Court Hearing is being arranged.
“In accordance with the 2011 Speedway Regulations, Mr Kennett’s SCB Registration is suspended for a period of seven days.”
