Im running much the same with sito plus and home cut standard crank (11mm off leading face) 24 carb with your exact other jets
Jetting around 122 to start and then drop down
Be careful those kits do about 25kms to the piston
double check bore clerarance. Outa the box mine was 2thou (should be 4thou)and you will see all the drama in my posts recently
the exhaust timing was only 140 (opend at 106 and closed at 246
Id be interested in your numbers to see if I got one of the mythical "Old batches" before they were "revised"
