R100S Tug Tuning / Trip Prep.

Spent the afternoon working on the R100S Tug engine. Pulled the valve covers and checked the valve clearances. Left side was right on....right side was a bit tight on the exhaust valve.
Installed a new set of points which ended up being faulty. Could not get any "spark" to the plugs after installing them. Checked the wire lead and everything appeared to be fine, but nothing I did would get them to function. I took a points file to the points I removed and cleaned them up as the contacts were still decent with no pitting. The rubbing block showed a bit of wear but not bad.
After reinstalling the old points, The bike fired up instantly...I ran a short ride. Once home I pulled the front cover again and I reset the timing. Initially tried to static time the engine but was getting some odd results. Hooked up my timing light and found the timing quite a bit advanced. The ignition / points plate needed to be turned quite a bit to retard the timing...nearly out of travel on the adjustment slots, but that is what was needed to get the timing set. Upon getting the timing in tolerance, I hooked up my "Twin Max" electronic carb balancing meter. Played with it for a while and got the carbs synched and working equally.
Went through the spare parts bin I carry in the sidecar. Added a pair of ignition coils to the "extras" box. Probably carrying way more spares than needed but better to be prepared, not only for myself but for other biker travelers in need.
 Spares on board:
2 ignition coils
2 alternator rotors
2 diode boards
2 extra ignition condensors
1 set of usable (used) points
3 extra carb floats
1 extra carb float bowl
2 40mm Bing diaphragms
2 32mm Bing diaphragms
Assortment of Bing Carb Jets / needles
3 clutch cables ( 1 new....2 used)
Extra Cable nipples for controls
2 containers with spare nuts / bolts
18" & 19" spare tubes
1 extra quart oil
Plus a lot of misc. small items. (zip ties, wire, tire valves, assorted o-rings, specialty tools)
During all the work performed today, I used  only my tools from the bikes tool set, other than timing light / Twin Max. Only used a couple tools from the "shop" tool box for convenience. I don't carry a socket set with me when traveling, but haven't had instances where they would be required. Performing necessary maintenance using only the on board tool kit is a good practice....if something extra is needed, it is added to the bikes' tool set. Obviously I carry a large assortment of tools, but all fit into the BMW tool roll which is stored in the Heinrich tank tool box.
An extra 1.25 gallon fuel can will be carried on the upcoming trip.
Next will be to start preparing / sorting through the camping gear and planning for "on the road" meals.
Hopefully our new tent will arrive tomorrow....I see by the tracking information that it was held up due to incliment weather for 2 days.

Wow! That is a lot of spares. Is all of I carried in the trailer now? My spares are limited to clutch cable, bulbs, tubes, fuses, wire, connectors and engine oil. Have you lost a carb bowl before?

Hopefully I don't have anymore alternator issues.

I used to work on the bike with just the factory toolkit but need to add a bunch of large wrenches when the sidecar was added. I haven't done that yet.

Never lost a carb bowl...but have seen it happen to someone else, then it was run over by traffic and smashed.
I have a plastic storage bin in the sidecar trunk (actually the seat back lifts out) with all the extra "stuff" jammed into it.
Also carry a small scissor jack in the trunk.
