Thanks Tim
I will get back on the sizes in the diameter.
It seems like someone in some cases have changed out the intake threaded nipples to a larger size or I really have a set of 30's standard scout heads. The cylinders still have nickle and was thinking they were from the late 20's and that somewhere along the way someone had followed the old blueprint for tuning your scout 45" 101 Indian for performance as dated in the year 30' or 31'. In the drawing it points out that the intake nipples are to be machined to accept the larger chief intake nipples. I have also heard rumors that there were rare cases that getting the larger carb setup was an option back then.
I'll keep searching, but I think I am closing in on what is going on.
I have been getting every nipple size that Indian made to have a better record. I have two more sizes to show up and think I will have a better answer. We shall see.
Thanks
Ryan
