sat my Category A (DAS) practical bike test today...

and passed first time! :D

to celebrate my pass, i went to my dads house to play on my bike which has sat there for 2 months waiting for a test date with good weather... and its broken.

i guess i'll have to wait just a tad longer, but ah well, its in the local garage now.

just thought i'd share

Ben :D
 
Congrats, shame about the bike though, whats wrong with it?

i have no idea - i'm fairly good with engines and electronics, but i believe this is a carb issue, which is beyond me, so i've left it to a pro.

sucks, i've been waiting so long for this, i'm not known for my patience either!
 
Well done mate :)

Can't believe the bike is ****ed though, why didn't you check before?!!?

Please fully star any swearing.
 
i had been starting the bike and warming it up to keep the life in it every weekend since i got it, it stopped playing ball towards christmas and i've been trying to fix it ever since :(


thanks for the congratulations, i'm chuffed :D

Grats mate. But you've only got yourself to blame for not getting to ride it yet 'aint ya :D:p
 
I think we may have found the problem on my bike...

you could say i may have found half of the problem!

got a replacement for the blown transistor package on its way, should be here tuesday/wednesday with any luck!

rather pay £1.50 for a transistor on the off chance that replacing that will work, than pay £80 for a new CDI.
 
That surely isn't the OEM CDI module is it? It certainly doesn't look like it's built to normal automotive standards.

Looking at the circuit that transistor is part of the high voltage generator, do the white and black/yellow wires go to the primary of a center tapped transformer? Unless you have found some obvious reason for the failure (e.g. chafed insulation causing a short) it's possible you have a shorted turn in the transformer, which will cause the same failure to occur again.

NO it isnt the OEM unit, its a derestricted unit (probably from hong kong or china)

it produces a 12v high CURRENT, not high voltage (its a transistor)

there are two transistors in the CDI unit, one for each primary coil on the two coils.

i'm going to test the coils before i put the CDI back in. as well as check the wiring to the coils for nicks and being trapped.
 
Fixed the CDI (hopefully)
