OOOOPS!!

They cost about 50 bucks.

If you use one, turn the bike upside down and blow the chips out with an air hose!! Or......make a very tiny vacuum attachment that will fit down the sparkplug hole. The chips might pass the exhaust valve without doing any damage but.................

Next time start threading the sparkplug in with your fingers and not the air wrench

The best way to start a plug is find a little piece of hose and stick it over it, so that it is tight enough to turn with it, but loose enough to slip if you start cross threading. You will never strip it then.

This is exactly what I do.

you can coat the threads with grease to catch the chips. worst case if you cross threaded it real bad you may need to install a timesert (better than helicoils) in the hole.
Baum tools makes the best back chaser, but very expensive.

My motorcycle mechanic showed me that little trick. I have only had to pull my plugs once since then, but it was so easy to get them back in right.

i'm a dumbass. that's what's BEEN happening.

it all started on my morning commute to work... left laners are going 50 in a 65 so i zip past them going 90..

all of a sudden my bike acts like it's needing to be switched to reserve, but worse.. it's sounded bad, like a little 250 "jake brake" LOL i pull over and am freezing. all the jerkwads i zipped past are now passing me looking at me like i'm an idiot. LOL

call my buddy, we ramp up on his truck, he takes me home, i cage to work.

after work i check out the airbox - fine, all applicable hoses - fine.. so i pull off the plastics and the tank - check the plugs cables, left is disconnected (duh), so i reconnected, and it's won't crank well..

so this morning i go get plugs and get home.. right is out, gap it and put in.. easy, they way i do it is finger tight, then 1/2 turn a wrench, don't even use a torque wrench because with the anti-seize crayon on it, it can throw off torque values by up to 30%. also, ngk specifically says to do this - all you need is to get to the crush washer.. also, kawasaki give you the best little sparkplug tool, you don't even need to take the tank off to use it.. it's specifically for this (has the little rubber in there that holds it..)

so next comes the left - i use the tool and it's already out!!! f### me!! i need to do my maintenance a little more often LOL also this plug is not even gapped!! so i don't know what happened when i lost power if the threads failed due to heat/carbon build up or it collasped and the piston bitch slapped it (i don't think it could go farther in, i don't think the head would let it go that far in).. maybe it knocked off the plug cable, too, i don't know..

so i gap and slowly use go counter clockwise a few times to feel the "notch" then go clockwise to start moving in, i'm using my hand (not knowing that the threads were at the level of FAIL of Mark Wilson).. after about 270degs, it just stops. i go backwards again, and remove the plug looking for shavings and/or carbon build up... nada, so i try again only using my hand.. i'm doing this back and forth stuff for about 20 mins to see if i can "clean" the threads.

then i get extra stupid.

the grease method is what i'm going to do

i'd go with a timesert over the helicoil as well..

my worst case scenario is to pull the head and take it to a machine shop..

i have seen some heads on ebay pretty cheap too, i may do that..

I crossthreaded a sparkplug hole in one of my Dads Austin Mini motors. I got to take the head off and fix it with him growling over my shoulder

the little ninja 250, daily commuter

NJL · #15 01-18-2009, 10:56 AM

well gonna go around town today and search for the tool.. what a drag..

Joe Gress · #16 01-18-2009, 02:51 PM

This is really funny coming form the guy that said he wanted to start throwing spark plugs at slow drivers windshields.

NJL · #17 01-18-2009, 02:56 PM

Obviously I know how to destruct things with spark plugs especially engine heads. LOL hahaha

Joe Gress · #18 01-18-2009, 03:05 PM

So did ya find one?

Pilgrim · #19 01-18-2009, 03:24 PM

I'd say that if you use anti-sieze on the plug, you don't need grease. I had trouble following the description, but it sounds like the threads may have been compromised before this plug came out.

It also sounds like - if you're passing people at 90 when they're doing 50 - someone is highly likely to change lanes as you're passing and cause you a LOT of pain. Moderation would be a good thing.

NJL · #20 01-18-2009, 05:20 PM

the grease is to capture the thread shavings on the use of a backtap or timesert (with the timesert, i'd have to take the head off anyway)

as to the passing people
