With the BTV mc fully assembled then pull the ram all of the way out until it stops. Measure. Then push ram all the way in until it stops. Measure again. Subtract last measure from first measure and that will be the travel.

My personal opinion at this time is to forget about any DOUBLE outlet mc.
Add not any more complication to the this R&D project. The dual can come later. OR let me put it another way:
Suppose the BTV had NEVER become the controversy that it IS. THEN, we would all be driving around happier than a pig walllowing in shit with confident BTV's as a SINGLE outlet cylinder.

On ANY of the BTV mc's that u encounter be sure to put a magnet to the MC ram to determine if it is stainless steel or regular steel.

NOTE THAT some SS IS magnetic. I have no idea as to wheather or not the reproduction rams that are SS is magnetic or not. NEVER tried one. VERY high grade SS is NOT magnetic at all. Low grade is somewhat magnetic but not as magnetic as a similar piece of regular steel. I don't know what your experience level is with metalls relative to making such a determination of SS v regualar steel. But what i have explained above is the best i can do to explain it.
