Why wont it start?

[Ghetto_styles]

Okay, I finished rewiring my bike, cdi on, all earthed. But.....no bang?

It just wont ignite.

Any ideas?

Going to try a new spark plug if mum decides to come home with the tool anytim today.

I just went to take my spark plug out and it snapped off. So, it's off to the mechanics, let some other poor bastard worry.

When in doubt...........take it to a mechanic

Yeah and in future use a bit of oil or copper grease on the threads and just NIP the 10 mm plugs up to a good "feel" ... no need to swing off the spanner ... The least amount of tension necessary to do the job is the best ...

id be more worried taking things to a mechanic...theyll let the apprentice near it

and developing a "feel" for torques is a bit of an art...not that many tradesmen are much cop either

did you break the ceramic or the whole thread? you might be able to pull out the thread if you wedge something into the hole... happened to my mates xr100. try a screwdriver with a fairly wide blade thats wedge shaped, or a bit of hardwood.

then scream....BLOODY GORILLAS

Another reason WHY you should only NIP small plugs up is because they can "twist" as in torsionally flex ... that in turn starts a crack in the porcelain insulator ... I've come across heaps of NGK C7HSA plugs that were cracked deep inside with the result that the spark was jumping across inside the threaded section shrouded away from the charge ... They can start up and run OK the first time , then the bike won't start after it cools down ... porcelain under tension will crack as it cools after being heated ...

Yes , I don't trust most "mechanics" ... they're known as fitters a**hole* in the fitting/machining and engineering trades ...

Dads mate has a tool for getting it out. Sort of just goes inside and grabs onto something and I just twist 'er out.

The mechanic I know I trust due to growing up with the man and the only apprentice is his son who has been riding since before he could talk.

ah, the mighty ezi-out use a coarse tapered left hand thread...and are useless if you say, snap the pedals on your BMX...

pfft, why buy/borrow a tool when ingenuity is so much more satisfying? we are meant to be aussies
yeah, not all mechanics are lousy, just a hell of a lot of bad apples...
