Hey fellas, my 02 DS650 Baja won't start. I started it to take it out, it fired up just fine, but after that I accidentally hit the throttle while taking my helmet off the handle bars. After reving up for a second the bike died and will not restart. The battery is fine and I replaced the plugs but that didn't help! Any ideas? Thanks

 

make sure the gas tank is completly full and the valve on and cheak to see if you have spark.

 

do you have a aftermarket cdi and if so try the stock one

 

The carb is getting fuel, and I'm getting spark. I'm thinking it's my CDI or rectumfier. I'll have to buy some spares to check them out.

CDI

 

I've got another stocker CDI on the way as well as a rectifier, so I'll let y'all know what the outcome is.

 

How could a cdi or rectifier malfunction in such a way that allows you to still have spark but not fire? ( I guess it would be possible for the cdi to send spark at the wrong time...i.e. when a valve was open so there was no compression at the time)

Has this bike been running fine and suddenly won't start? Has this bike been sitting for a long time and this was the first time it was started for awhile?

I would look in your pilot jet and make sure a piece of debris did not plug it. Is it new fuel?

After that I would check valve clearance and compression......assuming the pilot jet is not plugged and your new electrical components don't solve anything.

One other thing......smell your oil in the tank. If it has a strong gasoline smell you might have floats that aren't shutting the fuel off entirely so you are too flooded to start. This will show itself by fuel in your oil. you also might see traces of this at the headpipe.

Just a few other things to think about.... [img]i/expressions/face-icon-small-smile.gif[/img]

 

The bike was running just fine prior to this happening. I bought a Big Gun CDI recently, but was sent the wrong year. So I pulled the pins and connected them to he factory pin outs but I could never get it to start, but every time I plugged the stocker back in it would fire right up. If the new CDI or rectifier doesn't solve my problem, I will pull the carb off and clean it (I need to rejet it anyway). It has fresh gas as well. It will be next week before I can check everything out though. Thanks for the help!

 

Ya, check the carb... it mite be restricted. It show fire although, but just not run well
