Working on my own motorcycles is always rewarding and although what I've done is by no means an exceptional feat, I am still well chuffed with the result (more testing will follow):
Apologies for the ugly mirror, but it was necessary for the MOT, which it passed with ease.
Notice the Holy Mountain in the background, the photo above was taken after I came up, over and down it, making for a proper shake down ride that revealed that everything is functioning as it should.
Carburation is responding in a predictable fashion now, and I will be able to adjust as needed once the breaking-in period is over. More on this to follow, as I can say that I have learned a lot about tuning Amals from this experience.
There is but one minor leak from the number 2 exhaust valve cover, all it needs is the cover itself sanded down and perhaps just a dab of sealant on the lower half of the gasket.
Otherwise, the Commando is now a real pleasure to ride, as opposed to how it was before.
