-  * The timing marks have been revised ​on all 1980 and later 1000cc (crankcase number 780-108-001 and up) and 1340cc models to enable ​the timing to be set electronically at the factory. This step will reduce ​the number of timing adjustments required during pre-delivery and set-up. The procedure used to set the timing is exactly the same.  +1965-1966 XLH had a 12v coil mounted ​on a two holed boss under the seat casting on the right side of the bike with an angled plate (31727-65) holding ​the coil on\\ 
-  * Only the timing marks have changed. The front cylinder advance timing mark has changed from a straight line to a 1/8" dot and the rear cylinder advanced timing mark now represented by a lazy eight. +Bracket (51526-52A) bolted ​to top of the seat casting over the plunger holes with an angled plate (31727-65holding ​the coil on.
