4 of 5 7900 piston and cylinder kit July 10, 2024
Reviewer: Travis  
Overall quality of cylinder is great. The piston has a defect on a spot of the top outer edge. Still usable but I'd prefer a different piston

5 of 5 New top end- second BB kit April 19, 2020
Reviewer: Anonymous Person from Windham, ME United States  
I have had 3 7900's, and I am down to 2 at this point.  After running them stock for about 4 seasons, I normally swap into the BB kit.  Always been good, this price is the best I have seen.  Last one was Bailey's, looking forward to seeing how this one holds up.  Went together fine, and the ring seems a bit better than the last one I had from Bailey's.  Casting seems fine, connecting rod holder-clips-nightmares are without ears (preferred), I have had the other AF type fail.  Overall happy, and have run my full tank at idle through it already, and it's going to work tomorrow.
