Thanks guys!
To be clear: my auto-decomp was not removed, and is not disabled - at least not intentionally! In my musings, I was wondering aloud about whether it was now not working at all after the dealer repair, considering how much harder it is to move it through compression with the kick lever. Also, it's dead quiet; the noise of the engine idle never changes now, even in the cold.
The engine will start and run with the decompressor permanently engaged.
I believe that's what mine was doing before the repair. For more detail, read this post:
http://www.enfieldmotorcycles.com/forum/index.php/topic,20143.msg221717.html#msg221717I can do a compression test - it's easy, after all! Singhg5 did one on video, and as I recall, Ducatti Scotty did it too, about the same time, and posted his results to compare with Singh's. Could be useful.
Gremlin, thanks for the sensor suggestion. I think it's too late in the season for me to effectively attempt such a test, but I'll keep it in mind for the spring.
AussieDave - thanks for the clarification about the filter chamber.
Ace - the dealer isn't the ideal option any more... 4 hours away, and now out of warranty. For the last two problems I went in with, they couldn't see/hear/feel/detect one, and determined the other was normal ops. I'll be researching how to check the timing...
Looking ahead: If I
do end up pulling the head, there's two valve cover gaskets and the head gasket... can they be re-used, or should they be renewed?
