Ignition Timing

I have a 1999 VFR800 and am having some troubles with the firing timing. The camshafts line up at there correct mark yet at the F mark on timing gear, the bike doesn't fire at that point. I checked with a timing light. I have tried different coils and didn't seem to change much.

Any suggestions and/or help would be greatly appreciated.

 

Does the crank positioning sensor test OK?

Have the cams been removed and reinstalled recently?

 

How do I preform that test? And yes I have removed them to fix valve clearance but reinstalled them correctly following the manuals instructions.

 

just how far off the F mark is it ? does the bike run ? does the timing advance correctly to the MAX mark ?

 

it fires at idle on the cam timing mark and yes it runs. after revving to about 5 thou it makes its way to the max mark.

 

thats normal, AOK.

 

Thank you for the help kind squirrelman
