Enjoy.

I follwed your steps but when replacing w/ a new plug I can only turn w/ fingers a few turns. It appeared to start properly but I had to use a socket to get it to turn further.

I immediately found your post, read it and tried it again. I can only turn the plug a few turns before it gets hard to turn unless using a socket. I checked the threads on the original plug as well as the new plug after removal and the threads look clean so I seriously doubt any kind of striping of the threads. Can I use some WD-40 on the threads?

Thanks!

Re: Change the sparkplug

Yes,you can use some WD-40 on the threads.Did the old plug come out easily? If so there may be some carbon on the threads.

Re: Change the sparkplug

The head threads will strip or cross thread before the plug.

WD 40, oil, or anti seize will work.

Re: Change the sparkplug

Thanks for the replies! I used WD-40 and it did thread a bit easier.... Tightened it w/ the socket and good to go...

Unfortunately my starting problem is more battery related that plug but the plug was due for a change anyway....

Thanks again for the great resource!

Re: Change the sparkplug

I thought the spark plug wrench was 18mm. This post says 17mm. Can anyone straighten me out on this?

Keep in mind I don't think just any 18mm socket will do it because the plug is pretty tight in there. I've not heard of anyone being able to use anything other than the Sukuki tool.

18mm thin wall socket will fit.That's all I ever used. :) :cool:

Re: Change the sparkplug

Great tip ! Me personally STRONGLY advise using a dab of antisieze on the plug threads. My personal rule of thumb "almost" any bolt that comes out and I observe the imfamous "white powder" on the threads gets antisiezed. The only bolts I don't antisieze are sprocket bolts and brake caliper bolts, those get Loctited ! :2tup:
