    What is involved in replacing these push rod tubes on a air head ( R80 ). I have a haynes manual but it doesnt really tell you much unless you want to do a total strip down . And I cant even see what goes on there as the previous owner has “fitted” 1/2 a tube of good old roof and gutter sealant to each side . These things are leaking overnight enough to leave a puddle on the floor

    Thankyou for those contacts Steve B. Apollogies for not introducing myself properly  but I dont think I will hang around ( Ive only just got here and already I have offended 1/2 the world ! ).I only bought the R80 because it was cheap, known to me  and it goes. Im not really a BMW person .My rides are a 97 900SS, a 906 Paso  and a 74 guzzi 850T ,all of which are either in storage or waiting to be fixed.and after a bad crash ( 900 SS ) a bit over a year ago I decided that seeing has how Im now shot of the wheelchair , it was time to get back on a bike  and as a friend had just bought a Buell and had the BM for sale , I grabbed it and got on with my life. Ill fix the bm up a bit and by then the guzzi crank assy will have been ballanced ( $$$ ) ………….. life will go on ( nearly blimmin didn't !)regards  Hamish

    Welcome to the forum Homer. None of us are BMW people either. We just ride them because we like the bikes :-). Heck, I don't even like boxer shorts. This forum is paid for by the members of the BMWOR, so we have a responsibility to them as far as content goes. It shouldn't be too hard to keep it family friendly.Changing the push-rod seals is not hard, takes probably about two hours per side. Just make sure you read up on the procedure and have all the parts handy. You'll need to take the heads off and the barrels. It's a good time to get rid of any carbon accumulation in there as well. All the parts are readily available and can be bought locally or if you want to save a little, from overseas.

    Thanks Kokopelli, I was kinda hoping  that I wouldnt need to get to serious in the dissassembly dept but ……..time to get a gasket set, and peruse that airhead website. I agree , haveing all the parts on hand and a bit of an idea of whats involved makes life easy.Ha ha ,I dont like boxers either, although they were easier to pull up over external fixators ( the metal framework screwed to the pelvis , femur etc ) than briefs

    They aint that bad. There is a bit of hysteria about cam belts,  and the desmo valves need checking regularly . I do mine at 5000k's ,if I dont flog it I can get 15000+km's with out changing a shim or a valve collett , having said that I dont want a 4 valve duke, well maybe an early 916 .  I guess they are like everything else in that if you use them hard  you have to put the maintainance ( and good oil ) in  or  they will blow up
