What Could The Problem Be?

[matthewmckay231]

hello, i have had a strabge problem with my bike.. The other day it was working fine would kick start first or 2nd kick. Went to start it today and it wont fire up. so i took the plug out and tested for spark and the spark plug is only randomly getting a good spark going to it. I have tried to spark plugs but still only randomly getting good spark. I know this must be electrical so any help would be appreciated. Could It Be The Cdi??? thanks Matt

I had the same problem when i put a irk in to my motor. I would get spark on and off at different times, i found out that it was the the spark pick up near the flywheel it must of had a broken wire in the line. See if you can get someones coil to try but my guess is it has something to do with the stator plate.

2 things
has ur chain recently come off?
have u got a spare cdi u can test

hey thanks 4 the replies... my chain snapped a fair while ago but the bike has been running fine since the new chain was put on.. the old one snapped ages ago. And no i dont have a spare cdi unfortuantly is there anyway of testing them? also i took the cdi off and when i shake it, it sounds like there is dirt inside or sumthing?? is this normal?

hmm i would pull ur flywheel cover and make sure that ur pickup is intact
ive seen them crack from bikes merely falling over

but a new cdi will cost u $5 or $10 and it will probably be ur problem
because of the wet weather lately alot of bikes have come into work with buggered cdi's

ok thanks for that mate.. i will go grab a new cdi from the bike shop and see how i go.
