Where would I get a used BMW R-series engine?

A mate's after a good, s/h 800/900/1000cc lump. No gearbox or clutch reqd.
1983-1990ish.
Any preferred breakers for these?
Cash waiting
Cheers,

wrong sort of "breaker". But you knew that.

 

Tried the usual suspects, ie Motobins and Motorworks?

 

Passed on the info. Thanks to all.

I have a bmw lump here awaiting a new owner, M reg r80 rt. Email me
for details. Reading area.

 

Thanks for the info. I've forwarded your post onto the bloke who's after the
lump (for a sodding *microlight* would you believe!!!).

Cheers,
JB

I believe.

But I'm fucked if I'd fly behind (or in front of) a twenty year old lump
of unknown provenance.

 

From a BMW, ffs.

 

Quite. Possibly the most complex suicide plan I've ever heard of.

To email me, neal at my domain should work.

 

I was just about to write that they are getting hard to find because of
fucking cunts in microlights. **** them all right in the eyes.

 

Fair comment.

I was a bit amazed when I heard this but it seems to be a common conversion.
Apparently he's replacing a ~900cc Rotax 2-stroke twin with the R100 lump in
order to improve 'mpg' (hours in the air).

That's been going on basically since those engines were current...

 

They fit twin plugs and have redundant ignition systems and one piece valves
making them about the most reliable power plant imaginable.

 

more feedlines'r'us? so early in the day?

 

Are the 1-piece valves readily available and suitable for road use?

I only ask as the 50,000 mile service is likely to happen in the next
few months.

 

The two piece valve works very well. It has good heat transport properties
and other advantages. They are a service item though, just on an extended
cycle!! If I had the heads off at 50k I'd replace them and lap the seats.

One piece SS valves are available, usually for tuned engines, but they have
their own issues. The OE stem and guide are very resilient together.
