Laugh now and get it over with


When i bought my bike the previous owner (a motorbike mechanic) said tht on some odd occasios both cylinders wuldnt fire up but by takin the spark plug out, giving it a wipe and it would fire up the cylinder tht wasnt fired. (This happened when we was there viewin the bike and it did indeed work)


Went to go out today and bike wasnt starting.. hmmm wasnt turnin over even with choke.

Jst the electircal start motor could be heard soo though hmm ill check the plugs!


Heres where i hit the problem.. on takin it off i obviously dont know my own strngth but it snapped :/


With the bit under the screw nut still in the hole :cry: :crybaby:


How the heck do i get this out without getting anything in the cylinder? :(


Any help appreciated

I don't understand where it's broken!


Can you show a pic?


if the hexagonal part that you normally turn is still there, just undo as normal.

 

i cnt get a picture as dad has camera at work and phone cable is at the girlfriends lol.

Everything under the hex-part is still in.. on the picture~(link above) its the left hand pic, the bigger one.

Literally the whole thread coil bit!

can you get mole grips or similar on the bit that's left?

don't chew it up though!

 

dnt think so there isnt enough showing out of the hole for grip. where the hole starts thts where its snapped.


Screw extractor? but the i may risk debris goin into ylinder which i think is a very bad thing?


maybe even somehow slide ascrewdriver down the hole? slightly bigger than the hole and try screw it out?


i rlly dno i jst wanna get rid of this bike ! nothing but hassle!

use small chisel or similar and hammer, tap bit that's left outside, see if whole lot will turn.

you don't really want to drill right through it, as you said, debris in cylinder.

you could try drilling down, without going right through, see if you can get extractor in.


could weld nut to it but i suppose there's no access


good luck! :lol:

you might be better off taking of the head, and removing it from the other side?


are you sure you were loosening it, these things shouldn't be that tight..


lefty loosey, righty tighty..


sorry, something i was taught a long long time ago..

i don't think drilling will work as these things have internals copper core, porceline shell (white bit) and then the threaded casing.. so even if you could make a hole, you would smash the porceline when using an extractor

I was debating that how difficult would it be to take the head off?

i even tried both ways to make sure


was debating wheter to check the other one but dnt wanna do the same ;/

looking on the web, the concus is this..


soak the area with something like WD40 or better..


try a stud extractor,


if this doesn't work, heat the area for 10-15 seconds then try the extractor whilst the area is still hot/warm,


repeat as necessary..


then i would get the hoover out, poke it at the spark plug hole using a nozle adapter and suck out any fillings that may have fallen inside..


or use a telescopic magnet wand thingy

Jsh, Try removing the other one, if it breaks then remove the head, it would be easier than fixing one and then finding the other one breaks also.


Google

spark plug extractor


for more ideas

still think the head's gotta come off, speak to your old man, see what his advice is, and see if you can find a 2nd hand head from a scrapper.. just in case

which way did you turn the plug?


clockwise or anti clockwise?


if you snapped it by turning clockwise, the thread should be relatively free (hopefully you realised that clockwise was the wrong way! i.e. clockwise tightens the plug) WD40 and gentle tapping in an anti clockwise direction should ease it out without too much trouble.


if it snapped when you turned it anti clockwise, then the thread is seized and you'll be lucky to get it out without taking the head off.


best of luck...

Josh smother the damn thing in WD40, give it while to try and pentrate in.


Then get a screw driver with the widest flat head you can find and see if you can get any grip on the burrs left on the metal.


Those plugs must have been hard and fast in there for you to snap them like that, and clearly they must have come out alot in their life i'd have thought they'd be really easy to get out. How old are the plugs?

If the bit that's left in is not too tight, insert a screwdriver, and tap it into the plug with a hammer (gently), then try unscrewing it. I did a similar thing on an old car and the remains of the plug just unscrewed with the screwdriver :cheers:

get a haynes manual and drop the top (head removal), you'll learn loads, and if you bugger it up, well its in no better condition than when you started, plus in its current state you wouldn't get much for it..


look on it as anything learnt now will come in handy later.. it's how i started with a busted gp100

give yourself a day to do it then you're not rushing, and youre only looking at taking of the top, the exhaust mounting and camshaft gubbins, not the pistons etc.. so should be easy enough
