Title: Spark plug re-theading .. can anyone recommend a decent repair kit?
Post by: AshimotoK0 on November 08, 2019, 04:05:26 PM
Can anyone recommend a spark plug repair kit for 14mm plugs? Some very cheap ones on eBay but not sure how good they will be. I have got a really nice CB250K0 cylinder head but one plug thread is stripped.

Now nearly 2 1/2 years on and still OK, but must admit its not had much use this year due to new hip.

I used the Vorlux kit but the US PRO looks to be exactly the same kit.

I used a vorlux kit on a Kohler lawnmower engine last summer, only issue, if you dont centre punch the insert or similar to retain it the insert comes out on the plug - mildly annoying if you aren't paying attention.  Actually came with 4 inserts of varying length so potential  for 4 plug threads repaired depending on length required. Otherwise a nice quick cheap and easy repair.

I put a drop of stud lock on mine and it's never moved. Between head and insert not between plug and insert.
