Engine Repair

George,

Just thought I'd give you a report of my recent engine repair. I had to replace the stator, which on a 1200 Wing involves pulling the engine. Since I had the engine out and had some coolant problems, I also did the head gaskets at the same time. On removing the rear engine case I found no sludge what so ever. The only thing was a light brown film on the inside of the case which wiped right off. While replacing the stator, friends suggested it would be a good time to replace the clutch friction plates.

I purchased an aftermarket clutch pack and proceeded to remove the old ones.
I was quite happy to find the old plates still well within the Honda specs for continued use. The wear limit is .126 ". The old plates were still at .140", and still had plenty of material left before reaching the wear limit. Imagine my surprise when I measured the new plates and found them to be only .139" thick. I went ahead and changed them anyway, just to have something for show and tell. I'll bring them down next time I can make a meeting.

Also, when I removed the heads, I found just a light carbon build up on the heads and very light carbon at the ring turn area. I use PI on a regular basis as this helps eliminate a backfire problem on the 1200's with the afterburn valves getting stuck from build-up. Also, the cylinder walls had all the factory cross hatching from the original honing. My compression readings have been within about 5 lbs. of factory new specs.

All in all, not bad for a motor with 186,000 miles and 25,000 mile oil changes!!
