Misfire After Valve Clearances Adjusted?

[unfazed]

Interesting point about the slack in the front of the chain, I did pull it as tight as possible....perhaps if I got someone to hold the crank on the timing mark I could try and pull it tighter.....

the thought of taking it apart in the street a fourth time does make me want to shoot myself, hopefully it will be ok.

Do you think slightly off timing could cause an intermittent misfire? I keep thinking that if the timing a set at a point why would it cause a misfire that doesn't occur at any particular point in the revs or throttle position.

The timing off one tooth on the fazer like yours is will have little or no effect and will not do any harm and definitely not cause a misfire.

It is common enough to put it back one tooth out as the exhaust cam rotates slightly as you put it back in. What you do is lift out the inlet cam then lift the exhaust cam  then lift the chain off the exhaust cam sprocket or rotate it back one tooth on the chain then put it all back together.

Chain replacement is not that big a job since split chain chains are available.
You were half way there when you had the cams out.
