Hello! May I raise an acute technical question/problem which I believe many motorcyclists have come across sometime?
This problem is a scored cylinder barrel on a 1924 Indian Big Chief, resulting from a piston pin coming out to one side. The pin has machined 2 shallow and neat channels in the cylinder wall of an otherwise little worn cylinder which also has little worn cast iron piston. I am reluctant to sleeve this cylinder and am considering 2 options; 1st -- to silver braze/ fill these 2 channels and then scrape/re-machine and Flex-Hone the cylinder, 2nd -- to use flame spraying with special bronze powder (35 Rockwell hardness) to fill the 2 channels, then re-machine and hone. I am more inclined towards the 2nd method as it usually does not produce bubbles or pores (it requires no flux) and provides a harder surface than silver.
If anyone has previous experience and "been there" I would kindly like to hear from you about possible amount of distortion (I am going to use Vermiculite powder for slow cooling).
