Has anyone done a slip-on and intake? If so, what jetting did you do? Did you see much performance gains? My daughter would like a little more power for sand and I won't buy her a z400 until she gets a little older and has more experience.

I can't seem to find any info on this. Any help is appreciated.

Nevermind. I decided I'm going to sell it and get her a Raptor 350. That'll suit her needs for the next 1-2 years until she's ready for a 400.

good choice! i was going to suggest a 300ex, but the raptor 350 goes just fine as well. those 250z's arent exactly "competitive" in the power market.

Ya. The sand really kills 'em too.
