Art708 Posted January 26, 2011 Author Share #9 Posted January 26, 2011 Thanks guys.... I would think that there's not much difference in 75-90 and 80-90 so I'll use it since I have it. Link to comment Share on other sites More sharing options...
KiteSquid Posted January 27, 2011 Share #10 Posted January 27, 2011 (edited) Is Castrol 75-90 synthetic oil good for the rearend on my RSV? I don't have an owner's manual but I think that it should work ok.....?? Thanks........ You can download the owners manual for your bike at starmotorcycles.com, once you register your bike. you can download the service manual for FREE by clicking some links on the left hand side of EVERY page here at the forum. On page 3-43 of the service manual Yamaha calls for SAE 80 hypoid gear oil graded GL4, GL5 or GL6 or multi-purpose SAE 80W 90 hypoid gear oil for the final drive on the 2nd gen bikes. In my bikes I also add a little Honda Moly60 to get some Molybdenum disulphide (moly) in there too. a pea sized ball is all you need. I would like to find a synthetic gear oil that has moly in it, but I have to buy a 50 LB pail which is a lifetime supply for may bikers....
