Does a LT500R have a power valve. My dads recently blew up and when we took it apart we had to disconnect a arm that was connected to a valve. I was wondering was this a powervalve he said it was a exaust dump. I think its a powervalve. what is it. there is a small window and the arm that is connected to this thing is behind the window.

 

Exhaust valve

 

THAT would be the suzuki power valve

 

Yeah I think that both the LT250 and LT500 both had power valves.

 

exhaust valve powervalve its all the same thing it a valve that closes at 4,000rpm and opens at 4500rpms

 

Yes that is the exhaust valve! You need it. Dont forget the way it was before. It gives you low end plus top end.
