We (dad, stepmom, girlfriend and I) rode to a BMW rally in Paonia, CO this past weekend. 

I spent the entire week every night last week preparing the bike... pulled the head, dremel'd the piston heads and cylinder heads and valves, removed the points and added dyna s, changed the rear tire, set the tappet clearance, set the timing and above all else... removed every stinkin' bit of grime.

On the ride there I realized that the guys that I had change the rear tire for 15 bucks per my removal of the wheel mounted it incorrectly and balanced it incorrectly.  The line that runs parallel to the rim was not parallel at all and when the BMW of Denver shop made adjustments the line was perfect and they simply removed 50 grams of balancing weights that the previous shop had installed.  how did i figure this all out... oh, the constant skipping of the rear wheel on the pavement for 300 miles and me mounted on a cafe seat w/ virtually no cushioning!

Once they fixed it, it rode superbly... after i advanced the timing a bit more.

We really didn't do any riding while we were there.  We just hung out w/ the 800+ other (mostly Beemer) riders and camped on a school lawn.  It really was a lot of fun to chat and make new friends that most of which we'll never see again.

Yesterday morning we headed out first for the gas station.  We filled up and I noticed a small leak from the fuel line.  I hoped that the leak would slow down as the carbs started using that fuel.  A mile or so down the road I looked down and the left sidecover was dripping w/ gas.  I pulled everyone over to fix the problem w/ emergency tape only to find the most horrendous oil leak I've seen.  Two bolts that run on the outside of the cylinders had sprung leaks at the o-rings at the base. 

We headed back to basecamp instead of further across Colorado.  BMW of Denver was generous enough to throw her in the back of their truck next to a new little Beemer dirt bike.  So, she sits in some dark corner at this point feeling very out of place surrounded by none of her own kind.  I'll go pick her up tomorrow or next.

Elizabeth and I rode back 2up on her 88 ex500 that we brought back to life earlier this year... So, let that be testament, Baby still has life in her and she's coming back apart... this time for all the goodies.  The head gasket was just a fix but, there is obvious rebuilding to do... who knows how long she'll be under the knife but, I promise you, she'll come out the other side feeling A-OK.

Here's a few pix to commemorate the little bike that could and cried when she had to go home...

If you're talking about what I think you're talking about, those aren't bolts.  Those seals do go South after a while.  You don't need an engine rebuild- just replace (all) the seals.
Dude- your 8 layers are showing!

i know the fact that the seals went out doesn't mean i need a rebuild but, other factors that i know of suggest that a rebuild is necessary.

i haven't looked at the schematics... if they are not cylinder studs then what are they?

man... you'd think there might be some interest in this thread considering how much i wrote and pictures i posted... oh well, guess i'm not very popular  :P :D

but, going rate seems to be one person posts per 30 views of threads these days.  tis ok... i had fun w/o anyone's reinforcement  ;)

Hey Heff!  Sorry to hear about the problems, but I'm glad she at least made it there.  How did Elizabeth feel about riding on the back?  Or did she put you on the back? ;D ;D

Hey Heff, sorry to hear of your break down. I've never experienced those "bolts" leaking,
can you post a close up picture of those bolts so I can eyeball mine?
Hope baby is well soon!

Heffay,  I know your pain.  Came in on 3 after 25 miles on new plugs.  I couldn't just rebuild the motor, I had to powdercoat everything, etc.  Anyway my "baby" is running great, other than a leak at the tach cable seal.  I actually enjoyed the rebuild,  but don't think I could stand much time without it again.

Those pictures are absolutely great.  I keep thinking to trailer out to see my cousin in the Springs, but it's just too damn far from Alabama.  Good luck with your rebuild.

i do believe it is a cylinder stud.  here's a pic of my spare motor as i haven't been able to pick the bike up from being transported back to the beemer shop.

there is probably an o-ring at the base that blew and i think one blew on one of the back ones too... i've just not looked at the schematic or been that far into the motor yet.

time to get my hands dirty.

i suppose you're partially right though ernie... it won't be a full rebuild but, camchain parts and all seals like you said.  i'll of course be measuring tolerances though and if i don't like them... well, that'll just have to change.

she's due for some new paint though.  my buddy just got a powder coater so that should be fun too.

i think i'm at the point where i can get started on the 400f too.  could just do them simultaneously and they can be reborn together  :)

Are you sure it's from the bottom?  I had a hellacious leak from the top of one of those cylinder studs after a rebuild.  It was hard to isolate the leak with the amount of oil pouring out.  There's a rubber "donut" that seals it up on top.  Re-torquing the head took care of it in my case.  Good luck.

Heff,

Sorry to hear about your bike. Guess there's worse things than riding behind Elizabeth. If you need a hand loading, etc give me a shout.

John,

Come on out to the Springs. Weather is nicer, sky is bluer, mountains are better. I'm sure your cousin would like to see you again and I'd love to ride with you.

yea... but, she did ride on the back... thank god or else i'd probably go crazy after 300 miles.

thanks tsfl... i'm not exactly sure so, i will keep that in mind.  i do have a stripped bolt in the rear that i must work on too.  and, perhaps, another one that is getting ready to go. 

thanks for the offer rx... just got it hauled back from the beemer dealer today.
