Hi all, I just finished checking the valve clearance Friday on my 2003 Silverwing and thought I'd post it for general information on the wear.
First inspection was at 7-19-2014 at 17,399 miles and the results are below.
Left intake---.007 and .007
Left exhaust-.010 and .009
Right intake-.007 and .007
Right exhaust-.009 and .009
This inspection: 6-19-2021 at 37,000 miles.
Left intake---.007 and .007 (same as 2014)
Left exhaust..010 and .010 (.001 greater clearance in one valve)
Right intake-.007 and .007 (Same as 2014)
Right exhaust-.010 and .010 (.001 greater clearance in both valves)
All readings are within spec. What it does show is that at least on my scooter, the exhaust valve components have opened up by .001 while the intake valve clearances remained the same.
Note: "Left" is the cylinder on the left side while sitting on the seat which is the #1 cylinder
I'll be rechecking these again somewhere around 60,000 miles.
I hope this info is helpful to some..Dickie
