Engine alignment in frame

[Texer]

Hello again. I have been getting ready to replace the timing chain, tensioner, spring and I guess the crank sprocket and bearing on my early number 1970 SWB r75/5. All numbers match.
Today's question (trying not let the Super Bowl distract me) is about the motor in the frame. It looks like is is about 5mm closer to the right hand frame loop than than the left. In fact it is as I measure it. Is this out of scope? I've ridden the bike 5 years in ignorance of this. There are spacers at each mount point as well as punched steel flanges on the forward mounts so I theeeeeenk everything is there. I've been playing with string to check the frame and it looks good. No crumple marks anywhere. I had of planned to remove the engine since I did transmission work a few ears ago already.

Thanks for any insight.

TLDR: engine is mounted closer to frame on right side. Normal? Issue?

I would guess that you didn't first use Google. http://w6rec.com/duane/bmw/frame/

Does it track straight? Does it have neutral steering?

If you still have questions, ask again.

So is mine and the engines never been out of the frame. It's normal and I suspect it was done to help provide rear tire clearance by pushing the drive shaft out a little to the right.

Thanks Duane and Barry,

As to tracking, it always seemed ok, but the head bearings needed replacing so I am not sure. By the time I noticed the engine offset the forks etc were off so I will have to rely on memory.
It's good to know that yours is similar, Barry.

If you read my article, then you would know that they vary a lot. Basically, no two are alike.

Duly noted. I pick up more detail in my re-reads for sure.
