Had my longest one day ride on the Henderson last weekend. Rode 400km`s on single lane country roads, including two mountain passes.

The first pass is kind of different from most mountain passes over here, as the climb is done by two very long straight hills, which the old De-luxe did easily in third (I thought). Having stopped at the top of the mountain for a while I found the exhaust valve on the rear cyl had frozen in open position when I was to continue my ride.
I had my 8" long home made valve plug wrenchlong with me, the one that I used to tighten the plugs after my renovation. I couldnt move the plug to get access to the valve, no chance. Had to ride to a nearby tractor workshop (on a three cyl Henderson) where we ended up using a 50" long arm on a power socket, using a hammer on the socket top to shock the threads.
When I finally got the plug removed the threads was OK and I could easily turn the plug back in by hand????
I dont understand why the plug was so hard to get out? I had used Never-Seez high temp compound on the threads before assembling.
Plugs where bought from Bill at St. Louis Henderson parts, great parts I think.
Anyone experienced the same problem??
Now I am seriously worried about the remaining exhaust valve plugs.

Kind regards
