Hi Jason here! New to the forum and excited to learn and 'talk' to all of ya'll. I live on the Central Coast of CA and ride a 1995 KX 250 2stroke. I ride Pismo Dunes, our local forest (Pozo), Hollister hills, and the Mojave desert a couple of times a year. Looking to upgrade to a 4stroke and will be soliciting advise as to what sort size and brand used bike I should look for...
Thanks for having me!

... ok, so not so unbiased but a light hearted debate on good vs bad on what you're thinking of getting. That is where/what you ride now HOW do you ride? Advanced, Intermediate, beginner...some of that will be directed at what size of bike you might consider... 

Welcome. I am far from giving advice, so good luck with the others on here. They have a lot of wisdom and some sick skills in the MX and Off-road world.
... I called it !
. Glutten for punishment you might call it!
