Sanity check
Hi guys, having researched the subject and while I’ve got the carbs off I thought id check the valve clearances. I’ve used the screwdriver pushing down on the closing rocker to measure the closing clearance as per the Ducati Tech video.
Would someone be so kind to sanity check my findings.
Valve clearances. 1993 900
Vertical cylinder
In opener 0.14mm. 0.02 over spec
In closer 0.29mm
Difference 0.15mm. 0.10 over spec
Ex opener 0.13mm. Within tolerance
Ex closer 0.18mm
Difference 0.05mm. Within tolerance
Horizontal cylinder
In opener 0.13mm. 0.01 over spec
In closer 0.13mm
Difference 0.00mm. Too tight, needs to be 0.03 - 0.05
Ex opener 0.15mm. Within tolerance
Ex closer 0.21mm
Difference 0.06mm. 0.01 over spec
