i have a 400ex and the decompression device on the cam is causing the exhaust valve to stay open. does anyone know what would happen if i removed it? does anyone else have this problem?

 

Most everyone removes the decompressor when installing a new cam. It won't hurt a thing.

 

I don't believe it will hurt anything, but it will put a bit more stress on the starter motor. All that devide does is releases the cylinder compression for the first few strokes just to make it spin up to speed faster.

 

..Umm i dont think you can just take it off?I beleve there are some oil holes in the cam that need to be pluged off?..Thanks
