Brush Research GBD40024 FLEX-HONE, 4 (101mm) Diameter, 240 Grit, Silicon Carbide Abrasive (Pack of 1)

Exactly what I needed.

I was worried about the size as the 3.78 inch bore of the 5.3 is on the edge of the range listed for this product. It did a great job and I was very happy with the results. I used motor oil as lubricant and did about 10 in out passes. Make sure to go slow on rpm and fast on the in out to try to get the 45 degree cross hatch.

I have a 2005 Honda CRV that was burning one quart of oil per tank of gas. YES you did read that correctly. Car was abused before I got it, but now I have to fix it. Pulled the engine apart and found scoring on the #4 cylinder wall and a damaged piston. Replaced all 4 pistons, rings, and rod bearings. Took this hone to all the cylinder walls with a little extra in #4. All the bores came out factory perfect, except #4 which I would give a 8 out of 10. You could still see some vertical lines but it was 95% better than before. Hondas stance is do not hone, just install rings, and if you can catch a scratch with your fingernail, the block needs replacement. Well I wasnt replacing my block, so this was the next best thing. Put it all back together and the engine runs perfect. Car does not burn a drop of oil and the oil is still golden. It would be black from blowby within 500 miles before. Very pleased! and highly recommended.

Used it to clean up cylinder bores 80cui evo harley

awesome---cleaned up a 7 inch bore cylinder 10 feet long and shows little wear---highly recommend

Used the 89mm size hone for my 84mm cylinders in my 52 motor and seemed to work good. Just lubed it up with some motor oil and followed instruction and the cross hatching seemed to come out really good, gotta speed it up on the last few strokes or else your cross hatches will not be close to 45 degrees which I found out quick enough.

Worked as expected

worked good, good quality, good price

Works great. Did a nice cross hatch pattern.

We needed this tool for rebuilding motors. Worked great.
