Frame Alignment
 
I'm pulling my R100GSPD to pieces following a prang. Nothing too major, just a crash bar bent, broken screen, mirror and indicator - front wheel washed out and dropped it. I notice when looking down on the engine (with tank and seat removed), the centre line of the top of the engine doesn't line up with the centreline of the top frame tube. I can't see any obvious damage- bent frame, forks etc but wonder if the engine is offset or tilted to the right ie: assymetric. I really don't want a bent frame. Anyone assist?

The engine is tilted slightly to the right.

...beemer frames get bent when crashbar is being used...

You do probably not need to do anything about it - but you will most likely notice that you can not let go of the handlebars anymore whilst driving ...

Seen (photos/homesites) some good frameworks done down-under - ask around. You will find guys who can help you double-check the condition of your frame, and help you improve on the poor Bavairan "bambo-fence" design. (My japanese bikes frames were far superior to the beemer ...).

If you look at the right side of the timing case cover you can see that the cover is "modified" because the engine is tilted to the right.

Timing case cover is #6: RealOEM.com � BMW 47E3 R 80 GS PROTECTING COVER - CHAIN COVER

There are four spacers used to center/tilt the engine. The spacers are not equal and if you mix them you will get strange results.
