Good morning all.


I have found that many engines have some valves that require adjusting more than others. Especially earlier in the engine's life. There's not necessarily anything wrong. I think it's a case of the various components bedding in differently.
SV's seem to vary considerably. In around 50% of the bikes I service, some bikes need valves need shimming at 15k. Whereas others that haven't ever had the clearances checked don't require any adjustment at as much as 40k.

My own 900 Diversion, that has covered a whopping 172k. All of the clearances have been adjusted several times. Except for one exhaust valve, that was adjusted once at 15k. Since then, it has had a consistent clearance of 7 thou (.178mm to you youngsters).


Cheers.
