Engine A –       1100 currently fitted to the sidecar.
Came from a written off ’99 LT with less than 90,000km, I thought it would be a good one but after purchase I found the wrecker/someone had been doing burnouts on the bike (badly flat spotted brand new tyre).  I had to replace 13 of the 16 valve buckets to make the clearances correct, that plus me running it up to temp before refilling the oil(my mistake) and it’s continual overheating (in stop/start traffic at any ambient temp) gives me little confidence in the long term future health of this engine.  Plus lots of vibes and it’s a generally noisy engine anyway.
(The previous engine (8V) used to cook too, I’ve now come to the conclusion that the cause is a blocked radiator(3 row) restricting water flow, there is nothing else left. I do have a good 1100 radiator to go in as well as a new fan)

Engine B1-       1100 from Jamie, 81,000kms. He badly over-revved it by changing down too many gears to overtake (never had a big bike before).  The result was a knock at idle in the upper rear of the engine.  I was given this after helping rebuild his bike with running gear from another bike. Thank you Jamie

Engine B2-       Jamies replacement(NOT in my possession), when replacing the running gear in Jamies bike we found various damaged bits, mostly caused by a ham-fisted mechanic.  The engine that came out(B1) supplied those bits: Timing cover stripped thread/pulled helicoil, Cam cover (gravel rash, ground through), one camshaft bearing cap (stripped thread).

Engine C-         A spare 1100 from Floyd that he’d stripped down to get some parts from for a project. Condition is unknown, 
Thank you Floyd.

Engine D-         An 8v engine with noisy main bearings, good runner otherwise.
 
B1 is the engine I intend to reuse. I’ve checked the valve clearances and everything on this one is 100%. It should be a good one once everything is sorted.

To put together a good replacement I’ve now taken:
·         Spring washer and starter gear from Engine D to Engine B1, a tab on the spring was broken, that was the cause of the knocking
·         Timing cover, cam cover and cam bearing cap from Engine C
·         Looks like D is going to supply some of the bits to locate the Hall Effect Sensor (missing from Jamies) and the water and oil pressure sensors at the water pump due to damaged wiring on engine.


Hopefully I’ll have it fitted and running in two weeks’ time, the sidecar needs to be on the road and reliable for a trip to Mungerannie for the 2nd weekend of August(the biennial Off Centre Run) and possibly returning via the Birdsville track. My leave was only approved a week and a bit ago, that's why the concerted effort to get it done. The outfit itself is also getting its fair share of attention, new sidecar swingarm bearings, new rear car tyre and new sidecar tyre, added 20l of fuel capacity, additions to the sidecar hood for the dogs comfort in case we strike bad weather. The list goes on.

Lots of planning.

Al

I have 2 good 1100 engine blocks with pistins and cranks
Either is yours for the asking and I could pack them up and send fairly quickly. They don't owe me a cracker as I never let anything go out as you have probably figured.
One is absolute bare block and the other has the sump as well. Both are fairly low Ks

What year did the 12 rivet start?  The 8v with bad mains has a very quiet output shaft, no knock whatsoever at idle.  It's an 87 I think.

pretty sure the 12 rivet started with the 16 valve type motors production dates ..but just a feeling rather than an documented knowledge al

Any 8V after may 90 will most likely have a 12 rivet shaft.

ETK shows a supercession from part 11211460903 to part 11211461499 on Sept. 27, 1989 so any 4 cylinder engine manufactured in Oct. 89 or later probably has the 12 rivet output shaft.

My 11/86 RS has a 12 rivet output...

I have been under the impression/assumption that they stopped using the 6 rivet about early '86 model production. No?

http://hrsbstaff.ednet.ns.ca/bvogel/K100/K100.htm

I can honestly say that I don't know what the first owner of my bike, a BMW tech, did to it, as far as major reco goes, in the first 76,000 kilometres of its life, but replacing the OS would seem drastic.

I guess I only have to remove the sump plate to find out.  I will check for you Charlie.

cheers al
bit of a procedure none the less .. appreciate your efforts and thoughts mate

having a bit of a read around the place ...seems I might be kinda right ...the 16 valve versions started production in 89 ? which coincides with ducks comment as well ...;


so it figures that the production part shifted to 12 rivet about then ?  

cheers from up here

My RT is a 10/88 model and had the 6 rivet shaft, so later than that. It now has a 12.
