DIY R65 Maintenance and critical point check

[CAMPOA]

Hi All!!

As, around me, i don't have any good mechanics and as a matter of fact i like to spend time with my bike, i ask for advice in terms of maintenance and critical point check ups.

What should i do and how often?
Engine Oil change? how, witch oil, how often?
Other oils?
Filters? What filters, where, how
Carbs? should i use any carb cleaning product? should i dismount them and look for what?
Lubrification points? where are they and how should i do it?
Valves, spark plugs?
Clutch, how to i tune it apart from the lever?

Overall help anticipating problems.

If you can help me with answers and tutorial videos it would be awesome!

Thank you

Engine oil minimum once a year or every 6000 miles

BMW would say the same for Gearbox and final drive oils but frankly it's out of step with general automotive practice and there is no need as long as they don't get contaminated with water. For example I consider it quite unnecessary for a 3000 miles per year rider to change the transmission oils every year and do mine every other year.

Oil filter every 6000 miles but not necessarily every oil change for low mileage use.

Air filter every 30,000 miles

Carbs if unknown maintenance should be stripped and cleaned once then a balance check done every annual service. They have a tendency for the space around the emulsion tubes to get blocked up and that should be checked every service by removing the main jet and holder.

Greasing points to do at every service are the gear lever pivot, the clutch operating arm and the swinging arm bearings. Longer interval for the head stock bearings and wheel bearings.

Valve clearances annually or every 6000 miles.

See attached service sheet for guidance although personally I ignore the item about re- torquing the cylinder heads as there is more risk than benefit in doing it.

WOO! Thanks!

Brilliant.

So i have to ask you,

Is it easy for you to pass me some video of all of the parts of the maintenance or, even1 or some?

Some "How to" guide.

Thanks!

[Barry]

For how to guides all the basics are covered in the riders handbook which is very good. If you don't have one I can post a PDF version.

You can search on you tube for videos or take a look here http:// http://bmwmotorcycletech.info/technical-articles-list.htm

Have a look at this guy on YouTube.

Once you get this video up there'll be a heap of links to other tutorials that he's done. It's all relative to stuff you might need to do on an R65. The only difference is that he's usually working on older BMW boxer engines (or airheads). The principal should be the same.

I've seen many of this guys movies; specifically this one, synchronising Bing CV carburettors, and fork rebuilding to name a few. Lots of other topics of interest too.

Engine oil change is to be done whilst still at normal operating temperature every 7,500 km (5,000 miles) or every 6 months. If the bike is ridden only for short distances, or outside temperatures are below 0 degrees Celsius (32 degrees Fahrenheit), change oil every 3 months or after not more than 3000 km (2000 miles).

If the oil filter has to be changed, remove it before draining the oil. Filter to be changed at 7,500 km.

DO NOT FILL HIGHER THAN THE TOP MARK ON THE DIPSTICK!!!

Total Oil Content for my 1985 R65 is 2.24 litres (4.0 Imp. pints, 2.4 US quarts) plus 0.25 litres (0.44 Imp. pints, 0.26 US quarts) if the filter is replaced.

Inspect gearbox oil level every 7,500 km (5,000 miles). Change the gearbox oil whilst still at normal operating temperature every 15,000 km (10,000 miles)

Oil content for the gearbox is approximately 0.8 litres (1.4 Imp. pints, 0.85 US quarts) Fill to the lowest turn of thread in the filler orifice.

The last time I kitted out both carburettors so they were all new inside, they lasted 12 years before the diaphragms began to leak again. Not sure how many miles that was, but I know the bike was ridden around Australia prior to that. I cleaned them with petrol. No special cleaner needed because I replaced all of the jets. Assuming that the engine is running reasonably well, the main thing I check out in the carbs are the diaphragms. They tend to get very thin around the top edges and therefore begin to split. I just bought a complete carburettor kit for my R65 and it cost about $350.00 AUD from BMW. You might get the kit cheaper from Bing. The cost is insignificant to me because I know I'll get another 12 years before they need doing again. Although expensive it's best to do the entire kit. You won't need to open them up for a long time.

To sync the carburettors when you get them back on the bike, see Chris Harris`s tutorial on YouTube.  

That'll do for starters. If I keep going I'll be here for hours.

Brilliant!

this makes me want to quit my job and spend all week in the workshop.

but i wont.

in terms of the manual and a pdf version, i would appreciate hugely!

Thanks again!

Awesome help!

I tried to post the riders manual PDF but at 5MB it exceeds the forum limit of 3MB for attachments so it won't work.

PM me with your e-mail address and I'll try sending it that way.

Barry, let me see if I can up your attachment limit for this...

Thanks Justin but it's OK,

I've e-mailed the handbook to our new friend in Mozambique and he has received it.
