Hello Everyone! I'm a proud italian owner of a R65 build in 1981 purchased in this early summer. I need a small advice about the lubrication:
the user book advice to add oil for the rear transmission into an inlet which does not exist on my bike , please see the attacched image.
I got point 1,2,3 no poblem with them but the book shows another inlet for lubrication ( in red in the picture ).
I guess the oiol for the rear transmission should go into point 1 in my pic but I'd like to be sure.
Anyone can please give a better advice?
Many thanks to all you.

Greetings cromocefalo and welcome to the forum. There is no filler point on an R65 at the red location.
Number 2 is the filler and breather plug for the Bevel drive and number 1 is the oil level plug for the Bevel drive. ie. when oil comes out of 1 after putting it in 2 you have normally put too much in! Best not to overfill here. :-[
Number 3 is the filler plug for the driveshaft.
Don't forget to use GL-5 spec gear oil in these areas.
Good luck
Will

Welcome to our site, I'd like to add that plug number 1 is prone to stripping out the aluminum case if over torqued, just a word of caution, as who knows how it's been treated by previous owners.

The older "smooth" final drives had the fill hole in the location you point out and the later "ribbed" ones have the filler at position 1. Possibly you have an owners manual for a 1979? I think they had the "smooth" final...
You have been warned to go at it with a light touch! ;)

Think Justin meant to say the filler was position 2 ;)
Position 1 is the overflow hole and as mentioned is easy to strip. I prefer to just leave it alone and pour a measured quantity of 350 cc into the final drive. Once you have a measuring cup it is easy and less messy to measure for gearbox, driveshaft and final drive.

Cromocefalo, I don't know if you have had the rear tire replaced recently and have mounting lube coming out , but there are streaks on the side wall of your rear tire, that look like you may have an oil leak on the rear drive. May want to investigate this before the brake shoes get gear lube on them.
-
Chris, I always thought that #1 was the "fill hole" and #2 was the breather vent. I do conceed, however, that some folks use the breather hole to pour in a pre-measured amount of lube so they don't run the risk of stripping threads...
-
First of all let me say thanks to all you for the quick and so detailed replies. I'm really impressed and at the same time I'm really proud to be now member of this community...I feel so much safe now :D
Ok as I supposed the point 2 is the main inlet for the lubrication so I will go on it. The streaks on the tire are due to an excess of oil I dropped into the lubrication for the rear driving shaft (you know is the inlet hided by the damper in my pic...) so it dropped out and it got on the tire. I will go carefully on the exhaust 1 as you adviced it's only that the inlet 2 seems really hard to open i tryed with my 17mm 'beta' spanner but it's a kind of blocked. I guess the previous owner of my R65 had the same trouble with it and maybe he was feeding oil trough the point 1 but I will investigate further.
Again many thanks to all of you for your so detailed answers. Herebelow my R65 on the way to Rome this summer ;)
Cheers. Michele.

...and a fresh crush washer! (get a torque wrench!)

<sigh>
I miss Italy. Tuscany was a wonderful place: Sienna, Gubio, everywhere you go a hilltop town. Not a bad bottle of wine or cappuchino anywhere.... 8-)

Chris is correct, the breather vent is also the filler (as indicated in the owners manual) on late models. I have always used hole #1 to fill through as it needs to be open for the level verification anyway.
-
I'm with you, Justin, but I am thinking that I may switch to using the breather hole for filling (if I can get that thing off
without stripping something - I don't think that mine has come off in a long while). It is easier than putting
oil into the rear horizontal opening with a big syringe...
:-?
-
I'm undecided. I find it is pretty easy to squirt grease through the little hole if you fill it from a new jug with the plastic tip trimmed to the right size. This plug is functional on all of our bikes but I suppose once I strip one out (probably the next change) my tune will change...
