Airhead in distress...

MikeO · 07-05-2004, 07:13 PM

I'm in Whistler, BC, and have just been approached by Molly...

...who has just ridden up from Seattle on her 93 R100R...

...and has lost a bolt from the left barrel of her engine...

It looks the same calibre as a spark plug - could a sparkplug be used as a 'get you home' solution - any suggestions?

She's also had her tent stolen - probably not her best week...

Find someone to garage her bike and let her ride with you.

A fix for her bike would be a good ice-breaker...

It's a prety standard metric bolt. Try threading a spark plug but make certain that the threads are the same. Oh and put some copper anti-seize on it before you put it in...the bolt that is...

Check the opposite side and mak sure that it's tight too....Good I crack myself up....there I go again!

I think the bolt thread is the same as the final drive drain plug....I've got one in my garage....oh never mind, you figure it out!

Cheers,

Go to an auto parts store and find a sump plug that fits and remember to lock tight it. Suggest that it might be appropriate that you follow her around for a while to make sure the bike doesnt break down

. She is a babe!

Isnt that for the secondary scavenging system used on later R's? I dont remember them doing away with it once it was in use. If they didnt do away with it, there is a whole lotta stuff missing.

At any rate, try metric sump plugs as has been suggested. If nothing fits, I bet you can epoxy a quarter over it. Or a loonie, as I guess the case may be. I could be wrong, but I dont think a whole assload of pressure goes through that hole.

It does, combustion pressure, it's open to the combustion chamber. When that plug falls out...and they, are known to do that, it makes a nasty racket.
Once the clean air system parts are jetissoned this hole is usually capped with a final drive drain plug.

According to the parts list it looks like a 16 mm thread .. possibly a 1, 1.5 or 2 mm pitch (16 mm come in all three pitches, sorry) . Oh it has a copper gasket.

The final drive plug (for that bike) is a 14 mm with a 1.5 mm pitch.

You might be best removing the one in the other cyclinder to get the right size from a specialist bolt supplier. If it comes out easily. If not then the filler plug on the bevel drive is 14mm with a 1.5 pitch, if that fits fine, use a plastic bottle cap - should fill the filler hole to stop most of the leak. Use some sliastic to stop most all the leak. If it is too small then it is probably the 16mm size, check the pitch to see if it matches the 1.5 mm of the plug.

Ah so. I stand corrected. You should be able to find the plug readily. I bet a similarly sized plug is found on other BMWs, Guzzis, Urals and japanese or european cars.

Mike-
It is 16mm X 1.5 pitch. I still have the clean air plumbing parts that I removed from my 92 GS and I measured. As Frank suggested though, remove the other one and take it with you for a depth check. You're going to want to Loctite it anyway- Red Loctite.

The clean air systems are removed because all they do is burn up exhaust valves.

And of course, more pics. Molly's a beauty.

Be sure to come away with her address so you can send her an ADVrider shirt.

Eurobiker · 07-05-2004, 10:49 PM

Better still, bring her to Ouray.

walkingbear · 07-05-2004, 11:11 PM

that is where the emission air tubes were located.
I will find out the pitch in the morning

Plug is an M16x1, 5 standard thread - hint - an Oilhead drain plug BMW #07-11-9-919-117

Did this on my old R65 and R100RT courtesy of the IBMWR tech pages.

Mike, give the supreme sacrifice, your own drain plug and maybe you will get lucky
