I appreciate your responses, and it appears the nays may rule the yays. I've searched the internet for comments and it seemed many of the negatives were posted in 2010 and earlier. I hope that may be an indication of better quality components being marketed now. The seller of the unit I recently bought said early on there were leak issues but improvements have been made in recent years.
jaydee,
Earlier this summer I did install a larger master cylinder which did increase slave cylinder extension. Moved from a 3/4" bore to a 1" bore, but the increase in pedal pressure was unacceptable.
I returned to the 3/4" master cylinder, moved some of the mechanicals around and eventually did get more clutch fork travel. But the means to achieve the end wasn't some of my best work. I expected it may not be the answer to long term reliability, so I'll give the HTOB a shot.
I'm still interested in more feedback!
Thank you,
David
