I have been collecting parts to upgrade one of my 50's with the Malossi big bore kit and I watched the Robot video a couple times. In it he says that (Vespa?) recommends checking the valve clearances at the first service (600 mi)? Maybe it is just his recommendation based on a lot of experience?
I want to independently verify this but I do not see that in my manuals that I downloaded. I have the LX50 workshop manual and the Owners manual.
In fact I am not seeing any mention of checking valve clearances anywhere! DOH!
Is it called something else?
