Compression is now 60 lb both cyl. Going to do the top end, what should the compression be when done? Also anyone know what the carb slide opening should be at idle. This sled is rode at 9000' altitude. Thanks :dunno:

Compression after rebuild should be around 120-130 psi a side. Not sure about the slide height but on my 400's the slide is around a quarter or half an inch off of the bottom of the carb.
