Illegal modification to crankcase breather?!?!?!

Seams pretty harsh to me. I'm not sure how much a damn breather hose is going to help a machine make more power. I don't know...

PENALTIES ASSESSED FOLLOWING AMA SUPERBIKE CHAMPIONSHIP FINALE


PICKERINGTON, Ohio (September 20, 2007) – AMA Racing has announced that riders Martin Cardenas, Jake Holden, Morgan Murphy, Shaun Summers and Aaron Yates have been penalized following the season-ending AMA Superbike Championship event from Mazda Raceway Laguna Seca on Sept. 16, 2007.


In pre-race technical inspection, the motorcycles of Murphy and Summers were found to be using engines that were not homologated for the class. In post-race technical inspection, the motorcycles of Cardenas, Holden and Yates were found to have illegal modifications to the crankcase breather tube(s).


Murphy and Summers were disqualified from the event and received six month suspensions. Cardenas, Holden and Yates have been fined $2,000 and will forfeit 20 points. Cardenas, Holden and Yates will retain their finishing positions from the event.
As noted on page 30, section 3.1 Homologation, a, of the 2007 AMA Superbike rulebook (www.amaproracing.com/rulebook), Only homologated motorcycles may be used in Supersport and Superstock competition.


Also, as noted on page 31, section 3.5 Engines, b, Except as noted, all internal and external engine parts must remain stock with no modifications….
(end quote)


Not homologated for the class!
Nobody could figure that out before the race????

Ilegal modifications to crankcase breather tubes!

Murphy's GSX-R600 had been built using GSX-R750 engine internal parts to boost displacement, and Summers' GSX-R600 had been fitted with a complete GSX-R750 engine.

Cardenas, Holden and Yates were using the breather mod.

Ah ha! That's fucked up. They should be able to open that up for racing.

How about bikes that have the california smog kit installed? Are they going to make every racer put one of those on now when they race in California? LOL!!!!

The Murphy and Summers bikes were found to be illegal pre race ("In pre-race technical inspection") Apparently one of them had a 750 motor, the other had 750 parts in their 600 motor.

Now the Jordon/Emgo stuff is a crock, given that they've been approved with that breather arrangement previously (over a couple of years time).

Edit: Damnit! Was looking for the WERA breather discussion for a couple minutes and you guys scooped me!

Part of the AMA rulebook allows for removal of some emissions stuff - http://www.roadracingworld.com/news/...?article=30320
"...The current routing system does use OEM parts, and does adhere to Section 1.21c, as well as Section 3.11 (Emissions Equipment), which provides that certain "emissions equipment may be removed"."

It's good for about 1-3 horse on the dyno on some bikes they wany it routed to the airbox so it chokes the motor instead out the exhaust blowing back at everybody else.
