Just picked up a 2012 KLX250s, wanted a smaller single track bike, smaller then my KLR. Anyways, it's been setting a week. Went out and drove it around the block a time or two today. After I shut it down and restarted after a dew.minutes it wouldn't stay running. I pull the choke, start it, push choke in, pull clutch lever, shift into 1st, KABLAMOBAM! Dies, did it a few more times then I left. Any ideas?

Also what spring mods should I do in the front to stop the dicing when I stop. P.O. installed progressive springs on the KLR, they worked good.
thanks!

 

racetech.com website is a good starting point for springs

 

Maybe the side stand switch
