Today I tested the lifted Y-
I raised the Y-
When I mounted the set on my track bike it turnout to be +/-
Her is the bike ready for its firsts runs with lifted Y-
The runs where pretty constant between 25,2 and 25,5HP
Here you have four runs
To give a better view, here is one off the best runs
25,5HP at 11043rpm
Here you have two runs
