I would suggest to send it out. I know it can seem expensive, but the results are well worth the money. I have tuned bikes in the past with fairly good results, but after having mine professionally done, I have a strong respect for the professionals, at least, the pros who know their stuff. Not all do, I have heard some riders with troubles.
Myself, I ride an 01 RM250, a bike with a reputation as needing fork work. I had it set up with suspension by Shocknut, a professional tuner who frequents this site, and I cannot say enough good things about his work. In the woods, it is SO versatile, it is almost amazing! I haven't yet been able to get it on the moto track for the final verdict, but I highly suspect it will work well there as well. :)
