Found two of the contingency items I think I'll need. These are the centre gearshift fork P/N 24212-MN5-000 and swingarm gearshift P/N 24213-MN5-000 out of New Zealand. Delivery is 3 to 6 weeks, works well with the schedule. From what I have read, and recommendations from members, have decided that this is a good idea considering the shifting issues that could ensue later on as I put more kilometres on the bike. Haven't been able to source the front gearshift fork P/N 24211-MN5-000. Will keep looking.
There is a damper "Plate B" in the clutch P/N 22322-MN5-000. I changed the one in my 1200 just after I bought it. The 1200 had towed a trailer, and had some 115K Kms on it. This plate consists of a spring sandwiched between two steel plates. The steel plates are riveted together with brass rivets. These rivets wear over time and have been known to fail. This item is also on my contingency list. Have found it in Europe.
I noticed that there are 10 friction disks in the clutch set I bought and that this seems to be common in other sets. The fiche indicates that there is a friction disk clutch "B" P/N 22202-MT8-000. I'm thinking that using one of the other friction plates in place of this one. Comments on this would be appreciated.
Noticing that parts seem to disappear quickly for whatever reason. Something like shopping at Costco, if there is something you think you might need/want, and intend to come back, might not be there.
Reading more forum threads on the 1500 engine, and it is interesting that the primary fix for a transmission issue is to purchase a used engine. Understand this as the cost to do a rebuild, gaskets, dowels, o-rings and the likes combined with labour can be considerable for a $100.00 part. Something like changing the air filter on an 1800, $25.00 part and approximately four hours labour.
If I wasn't doing the wrenching, I'd ride it until the engine failed, then assess my options.
