Just Curious (Yamaha Tech Q)
What are the ID and OD of Yamaha YBB-641 INNER slide tubes? What about the OUTER tubes? (Making a comparison of stuff I use compared with Yamaha parts.) I am curious about the 641 bore and the wall thicknesses of the two tubes. I have heard that the inners are of thinner-walled material than the other tubes.
