Speed fight 2 2009 No Spark

Will take photos tomorrow, I have ever panel of and cannot locate another CDI, the bike isn't a immobiliser one I have checked that already.

Will upload them first thing in the morning

 

Hello guys,

Partners has just got out hospitals so I can get the pictures today.

Just a update:

The bike has a wicked blue spark, I have tried to kick the bike over and every single kick I do smoke comes out of the exhaust,

If I keep trying to kick it the bike will back fire, I haven't managed to get it started as of it

What Iv Changed

HT Lead
Coil
Piston and barrel
Stator and pick up


Thanks

 

check the reeds and fuel quality

 

Brand new fuel inside and reeds have been cleaned too

 

hmmmm....
did you follow my advice about the choke curcuit? im out of ideas if its not that, possibly a blocked exhaust or crank seals.... but try with the carb/choke clean first, and maybe change the auto choke too

 

Crank seals or weak mixture is my guess. A weak mix will cause a backfire, a blocked exhaust just makes more noise.

 

Thanks for all your help lads...

My friend had a speed fight engine, so swap my piston and barrel also the stator, swapped it all over gave it a kick and what do you know it started

 

Must have been compression or a faulty stator then. Were the old barrel and piston scored at all?

 

I used the same piston and barrel and the same stator, so must have been the woodruff key or crank, or compression

 

or crank seals...

 

I see what you did there...
