CB500/550 / Re: Stripped bowl threads on carbs Helicoil guidance needed.
« on: July 23, 2024, 09:55:03 PM »
I have used a helicoil kit for 8-32 screws, repairing 7 of the 12 screw holes on my 77 550k. Also repaired a couple of holes on the S&S superleaker (Super E) on my harley. The kit had everything execpt the required drill bit to ready the hole for tapping. I believe it was an 11/64 inch drill required (apologies to metric folks). Only problem i had was breaking the tang in blind holes. Repairs seem to be holding.
