I like Amals .
When set up correctly , they perform well .
OK , they wear fast , but with rubber manifolds you can double their life .
over 300 000 km , they gave me very few problems , like f.ex. twice a piece of slide broke off , but the engine 'ate' it without further damage .
What I particularly like about them , is how they handle changing altitude .
Even at 10000 ft up , they will pull trough the rev range ,idle well and still start first kick .
By comparison , my brother's modern Bonneville (carb version) in std setting , will loose massive power above 6500 ft and refuses to rev over 5000 rpm .
( But I'm shure the knowledge that his keihins where cast from the right stuff was a real comfort ..)
I also get much better milage : 60 mpg (imp) .
Sleeved a few slides , using anti aircraft shells , but swiched to anodised as soon as they became available .
I would consider Jseng's flat slides if I where shure they can perform over a range of 10000 ft without rejetting .
My next set will most likely be Premiers .
Wish they would make them a little lighter though ..
