Need help quick!! 400ex ?

[ELewandowski]

I am going riding this weekend and now i cant get my 400ex started. I had it running 2 days ago, but yesterday it just wouldn't start. I checked for a spark and I'm not getting one, I replaced the plug and still no spark. Anyone have this problem before?

TIA

Is your killswitch on the "run" position? Is your key on? Check the stupid stuff first, cause thats usually what it is.

May be something electical. I would clean everything up nicely and see if it works. If you still have no luck, start checking for bad connections, or check for voltage. It is possible that your CDI or something along those lines has crapped out. Happened to my RM 250, but I get occasional on/off spark.

yep, checked all that, I dont have a kill switch, just a teather.

I'll try that, i'll clean everything up and see if it helps.

thanks chevyz, you called it. I pulled my 2 15amp fuses and they were encrusted in mud and sand. Cleaned it out and put everything back on, and is fired right up.

Thanks
