Hi all - a while back I posted a query regarding the acuracy of the 'inbuilt' timing scale inside the primary chaincase on Commandos. I decided to recheck the timing on my 920 using a dial guage etc. I retimed the ignition (Tri-Spark) based on my 'findings' - result - first time staring every time hot or cold (the first start was after standing for five months) - the bike runs better than it ever has --. I checked the timing based on the inbuilt scale and found that it was 4 degress out. This goes to show that I've been timing the bike incorrectly ever since I've had the bike (22 years).
