Occasionally I have heard rumors of problems with early AVL engines. One rumor was to the effect that pre 2002 AVLs had "lots of problems". The other was that the early ones had aluminum tappets which tended to bend. Sometime later the AVL was upgraded with new alloy tappets. I will soon have two of the AVL bikes on hand, one a used 2003, the other a new 2002. I am wondering what teething problems there were and what was done to upgrade them. Also when were these changes, if any, made?
The two engines will be in the 350 class but I imagine similar issues occurred with the 500s. Maybe, though, these problems had been worked out by the time CMW started to import them.
Thanks for any help.
