90-hour service 200 XC-W

My (recently acquired) '15  200 XC-W 2-stroke is coming up for it's 90-hour service.  I could take it to the dealer, but want to try the service myself.

What should be done or checked?  Is an oil change necessary?  Any other suggestions on what to check or clean?  I saw the thread on servicing the electric starter, but not sure which grease to use after it's been cleaned.

Thanks guys  :thumleft:
