Shakedown ride shook the spark

[guest1406]

Hi there,

After two years of building the project, I finally insured and took it for its first ride!! Exciting, believe me!
Yet it broke down ..

After riding nicely about a mile or so it suddenly backfired and stalled. I pulled over and tried to start it again it but nothing. So a push to a friends house (Including two bloody hills!!) it was.

On inspection I checked the plug and spark, no spark. So I changed the coil for a brand new one, exactly the same -  still no spark. There's power to both terminals on the coil. That's as far as my electrical knowledge spreads.

Any suggestions?

When you say you checked the spark plug, was it wet with fuel? If its an NGK, they do not like getting wet with fuel,I had experience of this happening,was the choke still being used?  Was the engine warmed up and off the choke?                         Suggest  using another new spark plug. Just thought,  I would throw a few clues in. Good luck.

Power to both terminals on the coil? Shouldn't it be just one terminal? The other being earth?

Plug was brand new, and then cleaned before trying for spark. At the moment I'm just trying to get a spark.

Pick up came yday, it was switched over and still no spark, thankfully an original coil was delivered today and I'll try that.

 Yeah , in my experience  spark plug was brand new, and cleaning it makes no difference, I assume its an NGK?Just try  another plug, before looking too deep.

Plugs were changed over to see if it was the plug as soon as i realized there was no spark.

Coil came, still no spark!!

On intense wire inspection i came across a very warped and melted CDI. So thinking that may be problem another one has been ordered. Serves me right for buying moody Chinese parts!

Cheers! Hopefully it does work - if so i have the chance to be a rider for an Italian Vogue Magazine shoot!!

I'll let you know how the cdi goes when its here!

Sounds interesting, what is it you,ve built? Must be something nice if vogue want it gracing their pages. Can you post some photos? Always interested in seeing specials.  Regards Michael

Sounds and looks interesting , certainly different. (No bad thing in my book) sounds like you,ve put a lot of time, effort and most likely money into it?  How did the vogue shoot come about, do you have links with the publication or did they just spot your blog and pick it up from there? Either way hope it all pans out well for you in the end and I,ll have a look on your blog spot as I,d like to see the bike in it,s finished form.  Keep us posted of developments.  Regards Michael

Cheers Michael! A fair bit of money yes! But honestly the way I see is, two years ago at the start of the build I knew nothing about bikes, and now I'm half confident around a bike and its opened so many doorways!!

The vogue shoot came about through a friend (blackskullslondon.co.uk) who's wife knew someone who wanted a few young bikers for a video a shoot. Its something for the young London bike scene and few of us fit the bill!

I'm in process of updating and re-picturing the blog at the moment.

Also new CDI comes tomorrow so I'll update the topic soon!

Young motorcyclists you say, that,d count me out then. DOH.  Still good to see "young" lads (girls?) getting their fingers dirty and then hopefully enjoying the fruits of their labour. Keep up the good work we need more young guns getting into bikes and we need more special one off builds. Regards Michael

[guest1406]

Haha cheers Michael!

Well yesterday I fitted the new CDI!

She started! A test drive around the block she was fine! Did a quick compression too and got 151 which is surprising

Another test ride .. . Happened again. A backfire, loss of power and no spark. Curse of the CDI

Im beyond CDIs and electrical components, but it was getting really hot when attempting to start and very rarely it would throw a spark out.

Any suggestions? I'll be ringing the wiring guy tomorrow and see what he says

Sorry mate but sparks are defo not something I,m that good with so anything I might suggest might just put you back further still. I,m feeling for ya, soul destroying stuff but keep at it, it WILL be worth it in the end. Keep me posted.  Regards Michael
