650/X-2 Spark--fuel--150psi copression---"won't start"

[JETSKIHORDER18]

I have a 1987 kaw 650 bought it not running. It had no spark, replaced the coil pack and now it has great spark with the plugs out.(laying on the head) turns over great and when i check the plugs there wet. But no start, any idea's.

Flooded? Check your reeds? pull the timing cover and check the flywheel and stator. Possibly the stator has moved and is not in time.
Seems like you have all the things required, compression, fuel, spark. But it's gotta spark at the right time too.

I'd definitely check reeds, then pull front cover and flywheel and check those parts out.

hummor me and add an extra ground wire from the ebox to the motor or preferably the battery. then be concerned with internals from there..

 

[JETSKIHORDER18]

How can i check to see if it's in time??

How wet are the plugs when you pull them?

 

[JETSKIHORDER18]

real wet, you can smell the gas

 

[JETSKIHORDER18]

I pulled the carb the reeds look fine, also pulled the pulse line and blew the gas out from the base, it was flooded.

I had the same issue, I sprayed carb cleaner in the carbs and it started right up. THis happened to me twice, both times carb cleaner sprayed in the carbs brought my motor to life. Just for grins Ide try this first.

 

[JETSKIHORDER18]

Will try the carb cleaner in the am, but if the timing is off how would i check it????

 

[JETSKIHORDER18]

No luck with carb cleaner, so i pulled the head. All looks good inside and the cylinders were all wet. So its getting fuel i'm sure. I think the timing is off, so whats the best way to check or change the timing???

front cylinder will be at almost tdc when you align the timing mark with the pointer in the timing cover hole. At TDC you should be at .065 advanced static.

Wow, thanks for the info but one problem, your talking to a newbie. Where is the timing cover hole and were do you take your measurement from.

 

[madscientist]

he is talking about the removable cap the looks like an oil filler.

 

[JETSKIHORDER18]

I have the cover off, so the markings are on the flywheel??

 

[madscientist]

with a dial indicator you can determine if your flywheel is in time, but if the stator behind the wheel has come loose it will not tell you anything about when you are getting spark. you may be looking at a fault stator.. let me see if i can dig up the stator values for testing.. you will need and know how to use a multi-meter for this.

 

[JETSKIHORDER18]

Have one and know how to use it. The guy i bought it off of said the coils on the stator were replaced.

 

[madscientist]

still looking for the values... if they were not replaced properly ie the anodized coating on the wire removed before a connection was made they will not work properly..

 

[JETSKIHORDER18]

He used butt-splices on the stator, looks like it is still in the factory spot (screws are still in the middle of the grove)

thanks jordan

 

[madscientist]

use a razor blade to remove the coating. you may or may not be able to solder. i would suggest an unshielded but connector ad self sealing heat shrink.
