I've already got wide shovel trees, but I know from history I need more rake with over 6! I'll work it out!Or take 3 degree wide glides and those special cups in the neck for some extra degrees?
Pete,this shows what you basically should have & how they work, these are big twin Yokes,
Servicars I believe only have one cross mount hole on the bottom YOKE, where as big twins have the 2 to choose from, & by reversing the fork tube to plug which is cross drilled off centre to give another 2 choices of rake,
i believe big twins have 2 holes through the bottom yoke so you get more choices,
I'm not sure about any slot that can go from 0-40 degrees without a stop, could someone have joined the two cross holes by machining them giving you a slot ?...
pics would help a lot when you can get them,
there must be a way to put them together & be safe without welding or the factory wouldnt have made & sold them, unless someone has beenplaying with them trying to reinvent the wheel,...
all i can think of is View attachment 273505
if the bottom Yoke has been altered already for some reason, but going through many pictures of adustable Harley yokes I havent found any with a slot anywhere...
the big twin versions are as joe posted earlier with a 'two location' slotting so you can increase trail or reduce. Mine are like that sketch less one hole. So just a single pivot, but there's not way to lock in the rake. I'm not sure how they do it.. but would you rely on a castle nut and split pin to hold it together if it came loose?
I'll do my best not to weld them.. but I've paid a small fortune for something I want to run!
