How about you concentrate on getting it running right...

Oh, hm, yes... However it is us not him, who keep on diverging :)

On returning to the other issues, try to remove the fuel rail once again and see, if you have spray coming out of all the three injectors, whilst cranking the bike... Also do the starter fluid spray test and if in the slightest doubt, remove the throttle bodies and check for tears in the rubber above the throttle bodies and the manifolds beneath. The rubber interconnections are cheap enough, so I would replace them, if I were you, the manifolds are costlier, so you might want try your heat shrink method. Also make sure you have spark at every plug, probably cranking for a couple of revolutions. However you should not overdo it, otherwise you will permanently close the starting relay... What else, yeah, fuel pressure - if you can borrow the same gauge, you used for the compression test maybe? I am not sure, if that particular one is good for fluids too though...

Hi, yes, I just explained my plan on the rubber bits. I’m not sure on the pressure gauge either.

Yes, I suppose we were replying at the same time :)

You can save a ton, if not using BMW branded but equally good quality stuff, but we have discussed that before...

tbh, I’m trying to find other stuff at the moment... not much going on in England. I blame brexit...

Ok.
Had the throttle bodies off today to check all the air intakes and boots,etc.
Good news on them. All fine,no splits or cracks.
Throttle bodies were caked in crud,so they are all cleaned up now.
Will endeavour to put it all back together tommorow.
One thing I noticed...the two little rubber 'vacuum ' caps(?).One was split,so I'm guessing that would be drawing air in,maybe?
Pipes all look ok,but I will replace those while I'm at it.( non BMW parts though).
When I bolt the boots back onto the top of the engine...good idea to use a little liquid gasket?
Thanks.

I think the bushings below the throttle bodies seal to the cylinder head with o-rings.  I would suggest that you get some before you reassemble them.  BMW doesn't list those o-rings as a separate part, but if you take them to a bearing/seal shop, they should be able to match them up.

And yes, those vacuum caps are critical to a good running engine.  Get new ones.

Cool, yes I did thought that they may need replacing. I shall see what I can find tommorow at our local trading estate.
Thank you.

Whilst having the throttle assembly on the bench,  you might want to check,  if the throttle linkage is unmolested,  eg silver screws still covered in blue paint.  Even if paint is still present,  I would check,  if the butterflies open at the very same time and by the same amount...  Saves you hassle down  the road,  when you'll get to sync the throttle bodies

Yes,all open the same gap,at the same time. Choke operates at the same rates,too. In fact,the choke is a very minimal opening,very slight,but it is even other all 3 bodies.

And apparently,there’s no ‘O’ rings for it. I just made sure every surface was spotless then used heat proof copper loctite sealant.
See what that does.
I have ordered a new ‘Z’ pipe for the crankcase, also 2 more vacuum pipe covers.

There appears to be O rings for the K100’s, but not the k75.

Ah yes. The piece broken off doesn’t go through to the other side. I see what u mean.
I am wondering if I could possibly repair it with a mastic based sealer, perhaps?

The damage isn’t all the way through, so I’m thinking is take the air thing back off, put a tiny bit of sealer on the stub of the box and push it back on,and put the jubilee clip back on, pushed up as far as it will go. Let it dry. Should be air tight then. What do you think?

Hi, I would just replace all three of them. It is a cheap part and takes the guessing out of the game, at least you will know, they are good and pliable for the years to come. Also get yourself some narrow hose clamps to tighten the stubs to the throttle bodies, rubber bushings to the throttle body and bushings to air collector box. You can get the BMW one use items, the fancy Suzuki stuff or just plain SS narrow clamps, which are a lot cheaper

bushings - 11611460755 around 4 quid each

that part no. 11611460755. Where do I put that into? If I tap it, it just comes up as a phone no.

That is a manufacturer part number, so just phone up the closest BMW parts retailer, and give them this number. Motoworks lists it, as 4GBP ex VAT - https://www.motorworks.co.uk/vlive/Shop/Parts.php?T=6&Q=FUA60755 , motobins' website does not like reference numbers, but they have them for 6GBP each, so motoworks is cheaper, james sherlocks wants the most, https://james-sherlock.co.uk/shop/k75-k100-k1100-k1200/fuel-injection-317/other-parts-322/airbox-to-throttle-body-rubber-sleeve-detail
