F4 Engine trouble, odd compression
In the fall my 2000 CBR F4 was running badly, smoke out the back, rough, then died. Layed it up for winter and now I'm getting to work on it again.
Step 1, check compression:
Cyl 4: 100 PSIg
Cyl 3: 0 PSIg (completely nothing).
Cyl 2: 130 PSIg
Cyl 1: 60 PSIg
Keep in mid that this is with a stone cold engine from the winter, it's about 15°C for the test.
I will do a leak down test next, but what in the world is causing 0 PSIg?
The bike has about 35000km (22000mi), no other noises (ie metal bike flying around in the cylinder) that I can hear. engine turns over fine.
