The plug diagnostics might not be worth much after just 1,000 - 1,500 km.
TPS still ok. The only two/three other engine sensors (old tech) ambient temp, barometric pressure and engine temp were functioning well (BTW: for those who ever wondered... the dash temp from the sump reads equal to the engine temp from the head)
Leak down test done yesterday:
cold test good 15 - 20% vertical, but ~70%
on the horizontal. (Don't get so excited just yet)
Warm up to 120 degrees Celsius..... just over 100 degrees there's smoke gushing out of the air box
Ok, so it was actually steam. We got rid of most of it (and later drained the oil). The air box was full of water from the two wet autumn months (when I didn't ride at all) and water came into the horizontal intake - maybe causing rust here and there.
Warm test good on both cylinders.
I'm glad that no serious and expensive damages were found, but I expect the bike to still under-perform. I won't know until spring. The only thing I have 'fixed' is the squashed plug washer and it's hard to know if that was the only thing wrong. What I don't like is that I'm now without a clue about what's next...
Injectors? We have very clean fuel here, so ..... (230,000 km old)
False air tested with Kent One Shot made for that purpose (and cleaning intake parts/ports)
Fuel filter? (150,000 km old)
The ECU map is good (if it was good on the Dyno it can't change by itself)
Coils? (230,000 km old)
Thoughts, ideas, suggestions?
