Racer Chuck Chouinard, who was stripped of his second-place finish in the Loudon AMA 750cc Supersport race over allegedly modified valves he says were only cleaned using Scotch-Brite, has now been suspended by AMA Pro Racing.

The suspension continues a crack-down on rider behavior by AMA Pro Racing, which fined Mat Mladin $5000 and one championship point for remarks Mladin allegedly made during a press conference at Loudon. Comparing an AMA press release on the fine and point deduction to a tape recording of Mladin’s remarks shows that the AMA release grossly misrepresented what Mladin said and how he said it. That case is headed for the courts, insiders say, while AMA officials are maintaining a hard line and have privately said that Mladin can go race someplace else if he doesn’t like it.

According to Chouinard associates, Chouinard has been suspended for one year for his conduct following his disqualification at Loudon, when he allegedly spit at an official, threatened to ram the second-place trophy (which he had been ordered to return) up an official’s ass, and came close to hitting an uninvolved grid marshall with his pit bike while leaving the tech area in a rage.

Chouinard and his team have denied all charges and said that he did not spit at an official, did not hit a grid marshall with a pit bike or intentionally even come close to the walking official, and did not threaten to ram a trophy up an official’s ass.

Meanwhile, Roadracing World today took possession of two valves from the involved engine and while preliminary examination showed no metal removal, detailed measurements and photos of the valves and stock valves using a microscope will be taken, and the results will be posted on roadracingworld.com.
