Stripped plug thread

[Moorey]

Last Thursday night I went over to Squires in Sherburn in Elmet [old bike night] on my CD175 for a change and thrashed the nuts of it there and back. About 1ml from home it blew the left plug out of the head completely stripping the thread out of the head. I ordered VORLUX SPARK PLUG THREAD REPAIR KIT M12 X 1.25 B5838  of Ebay £6.90 it arrived this morning and I decided to do the repair without stripping the engine.
I removed the exhaust and turned the engine until the exhaust valve was open. I put a air line into the exhaust and did the job with air constantly blowing out past the well greased tap. Every piece of swarf was immediately blown out. Anyone else using this method make sure you wear goggles or glasses. From start to finish and having the engine running again just over 1/2 hour. I wouldn't hesitate to use this method again.

That's useful to know, good of you to share your success story.  Any chance of a photo of the tool?

That's really cheap compared to the other kits.  Worth having one tucked away in the toolbox 'just in case' at that price!  Thanks for sharing.

I did just short of 200mls on the CD175 yesterday and all was good.

Do you tap directly into the old thread and how is the insert secured so as not to wind out with the plug?

[Moorey]

There was no old thread left and the tap started quite easily without any drilling. I put studlock on the outer thread of the insert and tightened it in with the plug. I have had the plug out since and all is good.
