hey adam,
so what is the ride like before you do all the goodies to her?
i'll never forget my first tiki on a beemer.
i don't remember the 70's model it was,rode it very early 80's.
loved it.

sweet ride, very gutless. very comfy.
considering its age very impressive. sits happy at 75/80 mph. 170 miles to a tank not including reserve.
looking a lot better already, got the big grooming today. + pipes off, polished and leaks on joins sealed. also replaced the trim around the windshield.
heads off at the moment getting re-sprayed but need to do the valves before they go back on tomorrow night.

The engine holds 2.5 litres with a filter change, or 2.25 without. The forks hold 320ml each, BMW reccomend a 5 or 10w oil.
The driveshaft holds 260ml.
I have the book here if you have any other questions.
Edit, the tappett clearance isint in this book, its just an owners handbook, i have a couple of haynes manuals at work for these, but i set my race bike tappetts to 4 thou on the inlet & 6 on the exhaust.

[Winston001]

Inlet - 0.1mm (4 thou)

Exhaust 0.2mm (8 thou)

ATF(plain non new improved stuff) for forks if you're into budget motorcycling. Gearbox oil for the final which funnily enough the same a as the oil in the gear box. The 80-90 weight stuff.

[MaxB]

Hypoid 80W90 gear oil.

Gearbox needs 800cc. Driveshaft needs 150cc and the bevel housing about 350cc. 2 x 1 litre packs should see you through.

I use Motul 5wt fork oil for the er.. forks

Don't forget the driveshaft splines!

Special pixie grease required.

once again a huge thanks to all who are helping.
got the valve clearances done tonight after work, plus cleaned the air filter, repaired a small tear in seat and a small crack in dash.
also put the freshly painted rocker covers back on.
had a friend round for dinner and their mouth dropped when i told them it was a 1987 bike. it is starting to look great.

i did not ever know that the gearbox, shaft and spline needed to be oiled independently so Bonez and MaxB i cannot thank you enough. needless to say there will always be a beer etc in Paparoa for you.

think i am all set to do the spline,shaft,gearbox.
need to do the fork seals with the fork oil and i know nothing about it???
also engine oil. not sure what kind of filter i need?

thanks again and if any can help further i will be stoked, i am already stoked so i guess even more so.

will post some pics when i finish the cosmetic stuff ( not much left to do, just a bit of touch-up on the stone chips etc and cleaning the wheels )

the only other issue is a squeaky kind of noise from the upper engine i think, but i do not plan to worry about it till the basics are done as it may go away anyway. and i suppose i need to strip and clean the carbs but that should not be a biggie.

Workshop manual link is in the manuals sticky if you needum.

had a look at the spline lube method, .looks sweet

[hospitalfood]

ok, the rear hub/ ( bevel drive? ) looks easy enough to lube.
think i need to drain gear box then pull to do spline lube with the molly grease ( what the fuck is that ) the re-attach gear box then fill box with lube. so far so good.
i can see where to drain the drive shaft but no idea where to re-fill with lube.
also have no idea where the engine oil filter is kept.....


fun fun fun.

Look for a trianular shape cover held by three allen screws lower right front of the engine just above the sump gasket. May have oil cooler lines attached.
