After struggling with MMPs thinnest sabot in my tight Triumph's bore, I took Grouse's advice and polished the bore 100 strokes with JB Paste and flushed it with boiling water before and afterwards. But after running clean patches thru the bore with light oil, I cannot get the patches to come out clean looking - they're always still dirty.
When I used Triple 7 in my MK85, I would suction pull the hot soapy water up and down in the bore and afterwards, the final patches came out reasonably clean. Is this just the nature of steel barrels or am I still not getting it perfectly clean? Thanks.
