How easy does one of the old plugs screw in? That way you know if it's just the new spark plug.
Worst thing I had happen to me unexpectedly on a TL1000: Spark plug broke off the metal part you screw in. Just twisted off and I slowly screwed it in with the wrench, no force required, just like I did with the other one before until I torqued one down.
thanks moto joe, So drop engine is less /complicated/work than just remove head? I would have thought not but by your reply I guess I am wrong. If I drop engine, will I hafta completely seperate rest of bike from engine in order to perform work or can I do it by just lowering engine to floor? This is a major undertaking fo rme and I hate to be doing that kinda invasive work on my baby as I really dont know a whole lot and I'm afraid of something else going wrong in process, but I dont have the income means to just up and take it to shop... I bet thatd be expensive job. What? ballpark 500 bucks?... I dont have that . thi ssucks
Dropping engine is far easier than pulling head. Yes. And the head can't.be pulled engine in the bike anyway (no room) so dropping it then pulling the head is the natural progression regardless
Always thread the plugs by hand and I always turn the plug counterclockwise about a turn and a half until I feel the plug drop into the threads correctly .
Op did you try putting one of the old plugs back in ? Could be the new spark plug has bunged up threads to start with .
you dont need to remove anything at this point i would try putting back in one of the original plugs to rule out a odd thread on the new plug, also srart up the engine on the three cylinders give it a good revvv to blow the hole out clean then c if the old plug scews in. if it doesnt go and buy a intermediate tap at trade tool shop just give them the plug to match in might cost 8 or 10 bucks, and buy a bolt and weld it to the tap so you can wind it in a couple of turns thats all you need then just start it up give it a revvv and well its fixed

Starting the engine with a plug out is a terrible idea. It is just as likely to.suck something in as blow out.
And tapping the threads with the head on is a terrible idea as well. Metal shavings on the motor is not good.
Although I'm with the others on dropping the engine and removing the head to fix the threads . You can get a Tap and put some axle grease on it so that the tap catches the metal bits . It's not 100 % though in catching everything .
will this cut new threads thus produce lots of metal shavings or will it just fix the damaged threads, and just folllow the existing threads to bottom? ? I ordered this today and gonna try it. will this work?
Inspect the plug for damage or cross threading first. Get a new plug if that one has any signs of cross threading. Use your fingers or the rubber tube. Insert the plug and slowly rotate it backwards listening for the click as the beginning of the thread on plug drops over the beginning of the thread in the head. Gently turn it the right way and see if the thread catches. Be real nice and gentle...if it helps put a tube on other plugs too so you can see the proper angle easier.

yeah man ive tried. it refuses to go in. the other three went in no problems at all. gonna try the chaser. the very top is what is damaged, it didnt even turn really, just wont thread in true before acting like it wants to cross thread as soon as i start to turn it. and i have tried and tried to find the "sweet spot" its just not there.

I have don this several times on crossed plug threads, grease up the tap with some reel heavy grease and start the tap into the hole 2-3 turns and remove, clean the tap and regrease, continue till yer all the way thru.. worked for me..
Luck.
