Ok, went out and bought the Full Synthetic Mobil 1 5w-30, and the KN-147 K&N Oil Filter. Gonna go with this for the 500 mile oil change.
Wonder why Yamaha recommends semi-synthetic oil instead of full synthetic??
my take would be for seating the rings..

I have not run anything but full synthetic in EVERYTHING I own for maybe 20 yrs now....
Semi synthetic in this monster engine, not for me.
Well, gonna go with the full synthetic Mobil 1 5w-30 going forward from here too. Thanks for the recommendation.

I think it says in manual to run semi doesnt it? Makes no sense to me.
Break in is fine, but for life? I wouldnt.

We changed the oil and filter @ the recommended 500 miles while on our trip in the UP on 3 sleds. The original semi synthetic that came out was awful dirty, with white sludge and very thin like water on all 3 machines. We put in mobil 1 5w-30 full synthetic with a K&N filter, feel much better now. We managed without making to much of a mess but, we will be removing the lower panel rivets and replacing with rivnuts like Dan has shown as well.

Fyi Snoden, the parts for the lower panel mod are ordered. Thanks for the idea Rockerdan.We changed the oil and filter @ the recommended 500 miles while on our trip in the UP on 3 sleds.

Thank you Spaceman....your the best! We should probably check with NAPA, KB and Spanky, most likely they will want to get in on this as well. Did you order for RDW as well?
