Care to explain or expand this?the throttle off a trimendious amount of vaccuum is created in the cylinders more vaccuum that at any other time
I used to drive expedited freight to the Honda plant, north of Toronto. My last trip to Canada was a nightmare. I was driving a leased pickup with a topper on it, no company name on the truck. I appeared to be a "Traveler" (modern day gypsy) to the border agents. I was sent to Immigration for interrogation. I was called a liar, over and over by the Interrogator, this was not a short ordeal. It was not a good experience, this was pre-911. I refused every trip in to Canada after that, even with a passport.

While the engine may run with only 85 psi, it will not produce the torque or HP that it could if the engine internals were in better condition. After a top end re-build, a few years ago, my dry compression readings were in the 140 to 145 psi area.Cool!
People may recall that Daniel Black got readings of about 85 psi dry on Stella - and she runs great and he rides her all the time, so it doesn't seem like these things are all that critical. As we all know, these old XSs are pretty tough.

Daniel: from what I have read, it is very unlikely that anything in the bottom end (crank, big ends etc.) will need any work at all. These things seem to have been built like a battleship down there with everything running on balls and rollers.

The discussion about Stella was a tangent from the OP. Apologies for the confusion.Bob, no objections to your theory. Also no conclusions. I believe, if it is in fact gas fouling the engine oil will show gas contamination. (hoping) I also have no conclusive info that DB's rings are ok.. actually there is stated history of high mileage wear and low compression.. I suppose exhaust smoke would be a great indicater and would like more info on that ? Anyway, I just hope my own example of carb behavior can help DB determine cause.. doesn't matter to me to be right or wrong.. Thanks for your help as well ! -RT
