1994 Kawasaki KLF400 - Wont Start

[texaskaw]

fighting this thing for a month now.No spark at plug.

New ignition coil,pick up coil,stator,reg/rectifier,all new wiring.Started it up today rode for an hour shut it off.Tried to start later wont start.pulled plug wire it firing a blue spark while starter button is pressed.Tried new plug no change. It stared a couple times an ran for few seconds then died.Will CDI act this way? The reg/rectifier get pretty hot is this normal?

the cdi might act that way, but before going out and buying a new one, check the valves for timing first, it might be as simple as that. do you think the valves have been adjusted before?

[texaskaw]

checked valve clearance they are right. A blue spark jumps all over electrode but it is real small.I cant figure out how it was running fine cut it off now it wont start. Bout ready to throw a match on it..

[texaskaw]

Its fixed and running.......bad ground connection

[texaskaw]

well I was wrong.its dead again,

Even though parts are new it doesn't always mean they are good. I suggest you use an ohm meter to check the resistance on the ignition coil primary and secondary and any other parts including switches if all ohms out as good then I would suspect the cdi to be going bad or already gone bad. You really need the repair manual to test all these parts to make sure their in the correct ranges!

Now that I thought about if all these parts are in the correct resistant values and your still getting a spark I would look into whether are not your getting fuel to the cylinder?

CDI is bad. You can get them cheap now.
