Spark plug issue.. thread playing up:::: FIXED:::

[darrsi]

I[size=1em] had a similar plug issue once in 2009.[/size]

[size=1em]I unscrewed the offside plug, which came out fine, but I noticed a copper washer on the bottom of it (as well as the usual spark plug washer).  Apart from the bike's first service, I've done every one, and I haven't added an extra copper washer. [/size]

[size=1em]In any event I couldn't get the new plug back in the hole, it just locked up almost straight away. [/size]

[size=1em]I decided to re-cut the plug threads using an old plug that I cut grooves in with a dremil. [/size]

[size=1em]After much piss-malling about, I finally got another spark plug in the hole.[/size]
[size=1em]I used Iridium tipped plugs and I haven't changed them since. [/size]

[size=1em]The bike had done around 50000 miles when I changed them in 2009[/size]
[size=1em]And it's now done over 80000.[/size]

[size=1em]I reckon if I ever had to change that plug....that would probably be it..... because I have feeling that whilst I will be able to get the plug out, I don't reckon I'd get another one in. [/size]

However until now, I've never come across anyone that has experienced a similar problem.

Another good advert for spending a couple of quid more for Iridium plugs.
