I am replacing the cam chains so I have the heads off the machine. I look through the intake and exhaust side and can see the valves are not seated. I can see lots of day light in between valve seat and valve. Is this normal? Bike is an 07 outlander 650
If you have the heads off. Lap the valves, then reinstall the valves back in heads. Pour water in the top side of valve and see if they leak. A valve is a plug of sorts and when it is closed it should not leak air or water/gas. do a Google search on valve lapping there is lots to learn.
