Can anyone help with the valve lash specs for my 2004 kodiak 400,I am having a hard time finding or just not sure where to look.Have covers off and looks like someone used wrong wrench and started to strip nut so I want to make sure they got it right.Thanks in advance any help would be appreciated

Thank you for your help,I have now done that and it sounded better but still a rattle when running.I pulled left cover with water pump and found the oil pump shaft has sheered off on the end where it meshes with the water pump shaft.Not only that but there is a snap ring holding the plastic gear which runs the oil pump and it had slid to the left of the motor.I re-installed the plastic gear and cover and restarted the motor.noise quieted down but I need to replace that shaft in order for the water pump to work.I guess my question would be are these motors hard to split the case or do I have to in order to replace oil pump shaft and do you think if I use a heavier weight oil the motor might be ok.again thank you for your response.hope to hear from someone soon,Paul.
