I just swapped belts on my 900 motor, and it is turning over but not wanting to fire. it sounds like im off a tooth but all the marks appear to me to be lined up. i have done this before and not encountered this problem. pics for a sanity check before i break out the compression tester.....




anyone see anything amiss?

Everything looks slightly off, but by about the same and in the same direction.

I wouldn't think that's the issue.

Crazy question, if you pulled your plugs to turn the motor, are they back in and wires hooked back up?
Every time I meet a new group of your friends that understand you and your weird sense of humor I'm a little more amazed that there are other people in the world like you that lived through childhood - My loving girlfriend

Do you have plenty of fuel ?  Try taking out the plugs and squirting some into the cylinders.

If the layshaft mark lines up it can't be off.

How long since last start?  Seems like there's been a lot of fuel delivery problems lately.

From what you have shown us your timing is correct.  Going on the assumption that the bike was running well before the belt change and having nothing to go on besides your compression figures (a little off, particularly the 110 cylinder) and the test was done properly (throttles open, 4 revolutions) I'm going to guess you flooded the engine and the spark plugs are not happy.  Try some new plugs and see what happens.

Did you maybe pinch a fuel hose when you lowered the tank after the belt change?

...but the bowls shouldn't empty in the time it takes to change belts...it should at least start and run.

howie's suggestion of a plug issue is more likely, or if it sat a long time since you last ran...it bad ethanol fuel.
