Great place for Airhead work

It could be the engine breather. My 78 R100 was misting at the seams and occasionally making a chuffing noise. I've just fitted the later breather valve - no more noises or misting. Well worth the £10 for the breather.

Thanks again ALL for your help, just looked at the manual to see where the valve is located does seem to be located around that spot. Should i put a drop of oil on the disc to stop it or will it go/be ok? At tickover it is ok but as the revs raise it starts, then drops off at about ( well i think about 2 or 3 thou revs ) as i still need a rev counter and speedo used the push bike Sigma for the test.
Tester said thats ok lots of old bikes have them

Pics on Sunday when i have chucked some water over her so she looks clean.
Lots of cleaning to do, pitted bars, head lamp unit ( refector ) needs mending with a new one too.

still need a rev counter and speedo

Problem is they just don't come up very often. It's like trying to find a mechanical clock with white numerals or lens glass with the white ring around the outside. However, you can still buy the rev counter and speedo new. Not cheap though.

Hi Will, what new from the stealer any idea how much?

Glasses are gone as are the bezzles and the rev counter needle is OWAL some place, as i do not have any spare instruments at all to try a needle swap i do not no if the rev counter works or not... but she sounds nice

Hey BuB

If I understand you correctly, you have the housing and the rev and speedo units, but (a) bezzles missing (b) glass missing and (c) rev counter needle missing so you don't know if it works.

Re (a), you can buy bezzles, cost £7 each and part number is 62 11 1 356 676 (or check here http://www.motorworks.co.uk/bmw/pro...ode=20&partcode=RA&source_code=BA_15_20_RA_70)

Re (b), you can't buy new glass as a separate item I'm afraid. So you have two choices. Either have new items made from glass or perspex or buy a new housing for £100 which will include the main case (but not the back) and the glass, part number is 62 11 1 356 664 (or check here http://www.motorworks.co.uk/bmw/pro...rtcode=RA&source_code=BA_15_20_RA_70&spPage=2)

Re (c), this is a bit more tricky. The needles often come off. To check if the rev counter is working, how about a needle stuck on the 'nub' with a bit of blue tack? That should show the operation. If it works, you just need to find a needle off pretty much any period rev counter or speedo. This wouldn't be difficult to do, as you could buy second hand from Motobins, Motorworks, etc. But you'd have to buy a complete second hand rev counter just for the needle.

If the rev counter doesn't work, it depends upon why not. If no movement at all, check the spring is in place/not broken just behind the face. If it works but swings wildly, then try white grease on the two white plastic cogs at the back of the rev counter (one cog on the end of the rev counter, the other cog in the housing). If it still doesn't work, you could either try to have fixed or buy a new rev counter unit, part number 62 11 1 356 660 (or buy here for £142 http://www.motorworks.co.uk/bmw/pro...ode=20&partcode=RA&source_code=BA_15_20_RA_35)

Good luck and let us know how you get on
