That plug looks bad Roo never seen anything as bad as that even with a loose plug - has the tip melted as well?

Yup, the lot. It must have been hanging on for its dear life until it finally let go! One chance to fix it tmrw!

I’m conscious I’ve hijacked the thread somewhat, apologies…..

Start a new one Roo.

Quite a few VFR enthusiasts on here.

Mine was an 800Fi-1 (Y Plate). My first “modern” bike.

98 800 FI in Red. Wish I’d never sold it. Took me on multiple euro tours and only one reg/rect failure. Mint.

Loads of grease on the tap before use Roo, and spin the motor over before fitting new plug to blow any shite out

Crikey Roo. Just catching up with this. What a bummer.  And down to somebody else doing a crap job. Good luck with it mate...
One day I'll have the time to restore it, not just talk and dream....

Agree with Steve, could you put it over on another thread Roo ? We all like to yak about something like this  :)

Don't want to disturb too much the thread about John's eating exploits around the country  ;D

Though if that plug came out of the head like that, then I doubt there's much there to tap into  :o

Surprisingly there’s a fair bit but where all the kilter shite has gone in I just can’t get anything to start in there. It’ll have to be a new thread if not salvageable. Twitchy bum moment doing this but up for the challenge.

Worst plug I’ve ever seen tbh!

Old engineering method, in face of having bugger all correct tools....cut a U shaped V in a plug thread from one end to other. Leaving the sides vertical where they meet the thread top peak. De-burr the thread grooves with small file....you've now a "tapping" plug to use.

Put it in the hole, wind backward until you feel the thread lead drop into engagement with old thread (so you're not out of step on the threads) then start to wind it in slowly to clean out any threads that are there.

Use grease as Bryan says.

I’ll do it, but not from my phone. Back at a PC later.

I hope I never pull anything like that from any of my bikes Roo! Running lean? Looks like some one has attacked it with an acetylene torch. You definately win worst plug of the year! 😂
