Rocker arms - sorry guys something to worry about

Ok so here are the 'improved' New New Norton rockers and shafts. Looks like a slightly better surface finish and now has the rocker fitment cast into the top. Mould lines look very similar but not identical and still same configuration of bushes. Can't tell if any step in the rockers to retain the bushes. The end of the shafts have a part number and REV3 stamped into them. Interesting to compare to the Theil modded original rockers as above. Hope to fit in the next week or two - just polishing indents out of the posts then need to measure end float and decide on shimming.

Hi Clive , Good looking set of rockers and I like the LE left exhaust stamping etc. The shim sides of the rockers look nice and flat , and that should give you a good fit. Just as heads up , the rockers towers hold down bolts are different length intake side vs exhaust side . Don't mix them up , the longer bolts can break through into the exhaust ports these should be 5mm shorter. These are not the rocker shaft hold down bolts but rather the Rocker Tower to head mounting.

Thanks - much appreciated. I usually just want to get the thing all together and try it as quickly as I can, but I am purposely taking my time and not making any (expensive) mistakes!

Interesting - my bike is a late 2017 Euro4.... Ever seen any of these rockers on any other bikes? This would suggest a design change around this time and I was lucky to get mine from the bottom of the dodgy rocker parts barrel.
