It was suggested to me to do a compression test!
You do understand that you only have two cylinders and each cylinder has 2 sparkplugs.I'm sorry for the misunderstanding. Practically everything I've read, or video I've watched always made reference to "all" of the cylinders; they're never spoken of as "the other" cylinder, or both cylinders. So I assumed, wrongly as it turns out, that all meant all four. It is a learning experience, and one that I am extremely grateful for. I will see how high the oil brings it up in the morning.
It has been my experience that if you replace the core with a standard tire core the compression tester will not work properly. Did you use a core designed for a compression tester?Big discrepancy! I changed the valve core on the compression tester and it is now showing 110 psi's on the front cyclinder(s) and 115 on the rear two.
That's a four cylinder bike he testing, not a V-twin.I appreciate your thread and needless to say I hope you are correct and that I am complicating matters. Nothing would please me more than to learn that it is far less serious than I am imagining. However, I have changed the filter several times. I am on my third since the initial breakdown.
There is no longer any question in my mind whatsoever in regards to the proper method of testing for compression. But the idea that all 4 spark plug holes are to be tested did not originate with me, I got it from you tube. Here's an example: youtu.be/bwYkz5S4QCI How to test a motorcycle engine for compression.
In any event, thanks again for your uplifting thoughts!
