The previous owner suggested changing the drive shaft fluid. I have not picked up a book yet. What fluid am I going to use? 90 weight, 5w40? I prefer synthetics.

I don't know what drive shaft fluid is, but, I'll assume you meant rear drive fluid. Most folks use a synthetic in the 75-90 range.
When changing this fluid be mindful of all the holes/plugs. The top chrome thingy is the vent, leave it alone. There is a 'bolt' about half way up the drive, thats the level plug. There is a lower drain plug. The rear end holds 5.1 US ounces, or just enough for it to come out of the level plug while the bike is level upright.

I assume you mean rear end oil, as the driveshaft has no oil.

Use a GL-5 rated oil. 

Synthetic is my choice, but dino is OK.

On a side note, be extremely careful when tightening the final drive drain plug filler bolt cap, I've had one pop clean off when gently snugging it up. This happened even after having done at least 10 Valk changes over the years.

Remember, there's a link to download the book/service manual on the Norway site for guidance.

I like this stuff available at Wally World for a little over $5 a quart. Ichange out the final lube annually.



You might wanto also download a copy of the service manual at the link given below. Pay attention to the torque specs as mentioned above.

Dear friend

I quick look into Honda's service manual lists the final drive oil as "Hypoid gear oil, SEA #80" and the torque to be applied to the oil filler cap as 12 N.m (1.2 kgf.m, 9lbf.ft) and for the oil drain bolt as 20 N.m (2.0 Kgf.m, 14 lbf.ft).

You can order Honda OEM oil from amazon:

News Flash!!!  Honda does not make oil of any kind.  They take oils, slap a Honda label on it and charge you triple.

Lucas makes a very good Hypoid gear oil..........better than OEM

Any good quality synthetic HYPOID gear oil near the specified weight....like 75W-90 or so will be as good or better than the Honda stuff they sell in the small bottle for a huge price.

Also be careful with the gear oil filler bolt. I cracked one where the threads meet the cap by over tightening. Just snug cooldude

Chris, how did you determine that Lucas gear oil is better than the Honda OEM stuff?

A quality synthetic beats non synthetic every time.  Plus...I used the OEM stuff and I saw what it looks like after 10,000 miles.  After using the Lucas oil and it looks brand new after 10,000 miles, hands down, no contest.

Chris

Thanks for sharing the tip, I was able to find the same brand with the SAE 80W-90 spec (and the fact that is made in USA is a plus):
http://www.amazon.com/dp/B0007ZFTOA/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=PG06LGULZZOX&coliid=I15Z5WXLSQCMLT

Just curious, but what is the frequency you change the shaft oil?


Best regards

As long as that oil is GL-5 hypoid rated, then it sounds great....I change the oil everytime I lube the splines, which is at least every tire change (20,000 miles) or 10,000 miles which is half a tire.  Sometimes I get motivated and do a mid tire service

I am using the Lucas oil that Chrisj is showing here. I do a driveline inspection and maintenance every spring so I change rear end fluid each time. The rear end uses so little lubricant it doesn't hurt the bank to change it yearly. IMHO.

Yup, I sit corrected. My original response should refer to the filler bolt/cap. Those puppies are soft...  Undecided

Mobil One or preferably Red Line 75w/140 that I add a moly additive to and it works great. Its gears folks nothing to get that concerned about.

Bad news about the Lucas oil its not a synthetic unless it specifically says synthetic on the label. The stuff on ebay not the stuff Chris uses, is a blend of oils and additives with a fiber additive. I dont like the Lucas oil, personally. Also as said before the Honda stuff is not synthetic not made by Honda so like said any synthetic will do better than Honda stuff.
